3The influence of observation environment on background noise level of gPhone gravimeter显示文摘Based on the observations of 36 gPhone gravimeters in 2015, the background noise levels in the seismic frequency band(200-600 s) and sub-seismic band(1-6 h) are calculated. The differences in the PSD(power spectrum density) of each band of gPhone gravimetric gauges in different surrounding environments were analyzed and compared with Peterson's NLNM(new low-noise model) which is derived from the envelope at the power spectrum density of 75 seismograph stations around the world. The results showed that: the influence of station type on the noise magnitude of gPhone gravimeter is very small; The seismic band noise magnitude(hereinafter referred to as SNM) and the sub-seismic band noise magnitude(hereinafter referred to as SSNM) in the coastal gPhone gravimeter are higher than those of inland stations. Although the local hydrological change has a great influence on the gravity observation, the rainfall is not directly relative to the noise magnitude of the instrument. Except 3 coastal stations, the eight stations which had the highest amplitudes in the SNM were located near the seismic belt. This indicates that the SNM of the gPhone Gravimeter may reflect some seismic information.Compared with the NLNM model, the PSD of the gPhone gravimeter is lower than the NLNM model in the long period band(<3×10^(-5)Hz), indicating that the gPhone gravimeter is more suitable for detecting long-period signals(>10 h) than the seismometer.Xiaotong Zhang Ying Jiang Kun Zhang Xinlin Zhang 2017Geodesy and Geodynamics2017,8,6:4
4Effects of Gaussian filter in processing GRACE data: Gravity rate of change at Lhasa,southern Tibet显示文摘In this paper, the spatial gravity distribution over Tibetan Plateau and the gravity rate of change at Lhasa for different Gaussian filter radii are computed using GRACE data. Results show that the estimate of the gravity rate of change is spatial radius-dependent of the Gaussian filter. The GRACE-estimated gravity rate of change agrees well with the surface measured one. In other words, the GRACE-estimated gravity rate of change has a limited value as that obtained by surface measurement when the spatial filter radius reaches zero. Then numerical simulations are made for different spatial radii of the Gaussian filter to investigate its behaviors when applied to surface signals. Results show that the estimate of a physical signal is filter-radius dependent. If the computing area is equal to or less than the mass area, especially for a uniformly distributed mass, the estimate gives an almost correct result, no matter what filter radius is used. The estimate has large error because of the signal leakage caused by harmonic truncation if the computing area is much bigger than the mass distribution (or inverse for a small mass anomaly). If a mass anomaly is too small, it is difficult to recover it from space observation unless the filter radius is extremely small. If the computing point (or area) is outside the mass distribution, the estimated result is almost zero, particularly for small filter radii. These properties of the Gaussian filter are helpful in applying GRACE data in different geophysical problems with different spatial position and geometrical size. We further discuss physical sources causing the scalar gravity change at Lhasa. Discussions indicate that the gravity rate of change at Lhasa is not caused by the present-day ice melting (PDIM) (or Little Ice Age, LIA) effect because no ice melting occurs in Lhasa city and nearby. The gravity rate of change is attributable mainly to tectonic deformation associated with the Indian Plate collision. Simultaneous surface displacement, surface denudation, and GIA effects are not negligible.SUN WenKe HASEGAWA Takashi ZHANG XinLin FUKUDA Yoichi SHUM C. K.

5Microstructure and mechanical properties at elevated temperature of Mg-Al-Ni alloys prepared through powder metallurgy显示文摘Mg-Al-Ni alloys were prepared by powder metallurgy, and their microstructure and elevated temperature mechanical properties were investigated. Results indicate that, in addition to α-Mg matrix, both coarse Al_3Ni_2 particles and fine Al Ni nano-particles exist in the Mg-Al-Ni alloys. The strength at 150?C is improved with the increase in Ni content. Mg-18.3Al-8Ni alloy possesses a compressive strength of234.7 MPa and a yield strength of 146.5 MPa. Plasticity is also improved with a low concentration of Ni. Mg-11.3Al-2Ni alloy possesses a compression ratio of 17.3%. The phases of Al_3Ni_2 and Al Ni in the alloys block the movements of grain boundaries and dislocations during the deformation at elevated temperature. The existence of Al Ni phase provides a non-basal slip system, leading to the improvement in plasticity. Finally, the formation mechanism of Al-Ni phases in the process is discussed with thermodynamics and kinetics.Legan Hou Bingcheng Li Ruizhi Wu Lin Cui Peng Ji Ruiying Long Jinghua Zhang Xinlin Li Anping Dong Baode Sun 2017Journal of Materials Science & Technology2017,33,9:4
6Inhibition of M-MuLV reverse transcriptase activity by fullerene derivatives显示文摘Influence of fullerene (C60) derivatives on M-MuLV reverse transcriptase activity is investi- gated. Two water-soluble fullerene derivatives, fullerol (C60(OH)23-24) and trimalonic acid C60 (TMA C60, C63(COOH)6) are used in the experiments and their effects on in vitro reverse transcription-polymerase chain reaction (RT-PCR) of β-actin mRNA in HeLa cells are determined. PCR products are detected by agarose gel electrophoresis. It is found that the amounts of PCR products decrease with addition of either of two fullerene derivatives to RT reaction mixture. The inhibition of fullerene derivatives is dose-dependent, and IC50 values of fullerol and TMA C60 are 0.089 and 0.039 mmol/L, respectively. The amount of PCR products obtained by direct addition of fullerol or TMA C60 to PCR are greater than those obtained by addition of the equivalent amount of fullerol or TMA C60 to RT, indicating an inhibitory ef- fect of fullerol or TMA C60 on RT. The compensative experiment of M-MuLV reverse transcriptase shows that increasing enzyme amounts can antagonize the activity of fullerol or TMA C60. These results imply that fullerenes can inhibit M-MuLV reverse transcriptase activity, with the inhibition of TMA C60 slightly stronger than fullerol, and that their potential in treatment of diseases induced by RNA viruses such as leukemia virus needs further investigation.MENG Xianmei CHEN Zhe LI Bo ZHANG Yufei ZHAO Dongxu YANG Xinlin 2006Chinese Science Bulletin2006,51,20:4
7Effects of rapid quenching on structure and cycle stability of La-Mg-Ni-Co type hydrogen storage alloy显示文摘In order to improve the cycle stability of La-Mg-Ni-Co type alloy electrode, rapid quenching technology was employed. The effects of rapid quenching on the microstructure and cycle stability of the alloy were investigated. The obtained results show that the La2Mg(Ni0.85Co0.15)9M0.1 (M=B, Cr) alloy electrodes are composed of (La, Mg)Ni3 phase, LaNi5 phase and a small amount of the LaNi2 phase. A trace of the Ni2B phase exists in the as-cast MB alloy, and the Ni2B phase in the alloy nearly disappears after rapid quenching. Rapid quenching technology can slightly improve the cycling life of the alloy. When the quenching rate increases from 0 m·s-1 (As-cast is defined as quenching rate of 0 m·s-1) to 30 m·s-1, the cycle lives of the MB, MCr alloys enhance from 86 and 87 cycles to 106 and 119 cycles, respectively. On the other hand, the average capacity decay rates of the MB, MCr alloys decrease from 1.7172 and 1.7178 mAh·g-1·cycle-1 to 1.5751 and 1.3060 mAh·g-1·cycle-1 after 86 charge-discharges cycling, respectively.DONG Xiaoping Lü Fanxiu ZHANG Yanghuan YANG Liying FENG Meng WANG Xinlin 2006Rare Metals2006,25,z1:4
8Martensitic Transformation and Magnetic-Field-Induced Strain in Magnetic Shape Memory Alloy NiMnGa Melt-Spun Ribbon显示文摘A magnetic shape memory alloy with nonstoichiometric Ni5oMn27Ga23 was prepared by using melt-spinning technology. The martensitic transformation and the magnetic-field-induced strain (MFIS) of the polycrystalline melt-spun ribbon were investigated. The experimental results showed that the melt-spun ribbons underwent thermal-elastic martensitic transformation and reverse transformation in cooling and heating process and exhibited typical thermoelastic shape memory effect. However the start temperature for martensitic transformation decreased from 286 K for as-cast alloy to 254 K for as-quenched ribbon and Curie temperature remains approximately constant. A particular internal stress induced by melt-spinning resulted in the formation of a texture structure in the ribbons, which made the ribbons obtain larger martensitic transformation strain and MFIS. The internal stress was released substantially after annealing, which resulted in a decrease of MFIS of the ribbons.Shihai GUO, Yanghuan ZHANG, Jianliang LI, Baiyun QUAN, Yan QI and Xinlin WANG Department of Functional Material Research, Central Iron and Steel Research Institute, Beijing 100081, China 2005Journal of Materials Science & Technology2005,21,2:3
9Progress in Severe Convective Weather Forecasting in China since the 1950s显示文摘Located in the Asian monsoon region, China frequently experiences severe convective weather(SCW), such as short-duration heavy rainfall(SDHR), thunderstorm high winds, hails, and occasional tornadoes. Progress in SCW forecasting in China is closely related to the construction and development of meteorological observation networks,especially weather radar and meteorological satellite networks. In the late 1950 s, some county-level meteorological bureaus began to conduct empirical hail forecasting based on observations of clouds and surface meteorological variables. It took over half a century to develop a modern comprehensive operational monitoring and warning system for SCW forecast nationwide since the setup of the first weather radar in 1959. The operational SCW forecasting, including real-time monitoring, warnings valid for tens of minutes, watches valid for several hours, and outlooks covering lead times of up to three days, was established in 2009. Operational monitoring and forecasting of thunderstorms,SDHR, thunderstorm high winds, and hails have been carried out. The performance of operational SCW forecasting will be continually improved in the future with the development of convection-resolving numerical models(CRNMs), the upgrade of weather radar networks, the launch of new-generation meteorological satellites, better understanding of meso-γ and microscale SCW systems, and further application of artificial intelligence technology and CRNM predictions.Xiaoling ZHANG Jianhua SUN Yongguang ZHENG Yuanchun ZHANG Ruoyun MA Xinlin YANG Kanghui ZHOU Xuqing HAN 2020Journal of Meteorological Research2020,34,4:3
10Effects of substituting Ni with M (M=Cu, Al and Mn) on microstructures and electrochemical characteristics of La-Mg-Ni system (PuNi_3-type) electrode alloys显示文摘In order to improve the electrochemical cycle stability of La-Mg-Ni system (PuNi3-type) hydrogen storage alloy, Ni in the alloys was partially substituted by M (M=Cu, Al, Mn). A new La-Mg-Ni system electrode alloys La0.7Mg0.3Ni2.55-xCo0.45Mx (M=Cu, Al, Mn; x=0, 0.1) were prepared by casting and rapid quenching. The effects of element substitution and rapid quenching on the microstructures and electrochemical performances of the alloys were investigated. The results by XRD, SEM and TEM show that the alloys have a multiphase structure, including the (La, Mg)Ni3 phase, the LaNi5 phase and the LaNi2 phase. The rapid quenching and element substitution have an imperceptible influence on the phase compositions of the alloys, but both change the phase abundance of the alloys. The rapid quenching significantly improves the composition homogeneity of the alloys and markedly decreases the grain size of the alloys. The Cu substitution promotes the formation of an amorphous phase in the as-quenched alloy, and a reversal result by the Al substitution. The electrochemical measurement indicates that the element substitution decreases the discharge capacity of the alloys, whereas it obviously improves the cycle stability of the alloys. The positive influence of element substitution on the cycle life of the alloys is in sequence Al>Cu>Mn, and negative influence on the discharge capacity is in sequence Al>Mn>Cu. The rapid quenching significantly enhances the cycle stability of the alloys, but it leads to a different extent decrease of the discharge capacity of the alloys.ZHANG Yanghuan ZHAO Dongliang DONG Xiaoping REN Huiping GUO Shihai WANG Xinlin 2006Rare Metals2006,25,z1:2
11Effect of tetramethylpyrazine on the spatial learning and memory function of rats after focal cerebral ischemia显示文摘BACKGROUND: Tetramethylpyrazine (TMP) presents the effect of anti-platelet aggregation, reduces arterial resistance, increases cerebral blood flow, and improves microcirculation. OBJECTIVE: To observe the effects of TMP on the learning and memory abilities and the number of neurons in cortex and hippocampus after focal cerebral ischemia in rats DESIGN: A randomized controlled trial. SETTING: Department of Human Anatomy and Histological Embryology, School of Medicine, Xi’an Jiaotong University. MATERIALS: Fifty adult male Sprague-Dawley rats, weighing 250-300 g were supplied by the Experimental Animal Center, School of Medicine, Xi’an Jiaotong University. TMP was purchased from Wuxi Seventh Pharmaceutical Co.Ltd (Lot Number: 2004051106, Specification: 2 mL/piece). METHODS: The experiments were carried out in School of Medicine of Xi’an Jiaotong University from June 2004 to May 2005. The 50 rats were randomly divided into five groups according to the random number table method: sham-operated group, cerebral ischemia control group, low-dose TMP group, middle-dose TMP group and high-dose TMP group, 10 rats in each group. Rats in the TMP groups were immediately treated with intraperitoneal injection of TMP of 40, 80 and 120 mg/kg respectively, and those in the sham-operated group and cerebral ischemia control group were injected intraperitoneally by isovolume saline, once a day for 14 days successively. On the 15th day, the spatial learning and memory abilities of the rats were assessed with the Morris water maze test, and then the changes of neuron numbers in cortex and hippocampus were observed by Nissl staining of brain sections. MAIN OUTCOME MEASURES: The results of Morris water maze test and the changes of neuron numbers in cortex and hippocampus by Nissl staining of brain sections were observed. RESULTS: Finally 39 rats were involved in the analysis of results, and the other 11 died of excessive anesthesia or failure in model establishment. ① The rats in the cerebral ischemia control group manifested obvious spatial cognitive deficits in the place navigation trial and spatial probe trial. The mean values of escape latency in the sham-operated group, low, middle and high-dose TMP groups were obviously shorter than that in the cerebral ischemia control group [(23.92±2.21), (41.84±3.74), (39.50±3.80), (31.38±3.72), (61.60±3.61) s, P < 0.05-0.01]. In the spatial probe trial, significant differences in the percentage of time spending in the former platform quadrant and frequency of crossing the former platform site in the sham-operated group, lose, middle and high-dose TMP groups were obviously higher or more than those in the cerebral ischemia control group [(36.27±3.42) %, (35.84±2.54)%, (38.43±3.08)%, (36.51±1.96)%, (22.24±3.46)%; (11±1), (10±1), (8±1), (8±1), (4±1) times, P < 0.01]. ② In the morphological observation, the numbers of neurons in ipsilateral (left) parietal cortex in the sham-operated group, low, middle and high-dose TMP groups were obviously more than that in the cerebral ischemia control group [(98±8), (65±5), (53±6), (57±6), (37±6)/0.625 mm2, P < 0.01], but the number of neurons in left hippocampus had no obvious differences among the groups (P > 0.05). CONCLUSION: TMP can improve obviously the spatial learning and memory function after permanent focal cerebral ischemia in rats, and the neuroprotective role of the drug in cortex may be involved in its mechanism.Jianjun Zhao Yong Liu Xinlin Chen Jianxin Liu Yingfang Tian Pengbo Zhang Qianyan Kang Fen Qiu 2006Neural Regeneration Research2006,1,2:2
12ALK gene expression status in pleural effusion predicts tumor responsiveness to crizotinib in Chinese patients with lung adenocarcinoma显示文摘Objective: The relationship between anaplastic lymphoma kinase(ALK) expression in malignant pleural effusion(MPE) samples detected only by Ventana immunohistochemistry(IHC) ALK(D5F3) and the efficacy of ALKtyrosine kinase inhibitor therapy is uncertain.Methods: Ventana anti-ALK(D5F3) rabbit monoclonal primary antibody testing was performed on 313 cell blocks of MPE samples from Chinese patients with advanced lung adenocarcinoma, and fluorescence in situ hybridization(FISH) was used to verify the ALK gene status in Ventana IHC ALK(D5F3)-positive samples. The follow-up clinical data on patients who received crizotinib treatment were recorded.Results: Of the 313 MPE samples, 27(8.6%) were confirmed as ALK expression-positive, and the Ventana IHC ALK(D5F3)-positive rate was 17.3%(27/156) in wild-type epidermal growth factor receptor(EGFR) MPE samples. Twenty-three of the 27 IHC ALK(D5F3)-positive samples were positive by FISH. Of the 11 Ventana IHC ALK(D5F3)-positive patients who received crizotinib therapy, 2 patients had complete response(CR), 5 had partial response(PR) and 3 had stable disease(SD).Conclusions: The ALK gene expression status detected by the Ventana IHC ALK(D5F3) platform in MPE samples may predict tumor responsiveness to crizotinib in Chinese patients with advanced lung adenocarcinoma.Zheng Wang Xiaonan Wu Xiaohong Han Gang Cheng Xinlin Mu Yuhui Zhang Di Cui Chang Liu Dongge Liu Yuankai Shi 2016Chinese Journal of Cancer Research2016,28,6:1

18Terrestrial water storage variation in Hebei plain area of China,based on ground surface gravimetry显示文摘Variation of terrestrial water storage in the Hebei plain area from March 2010 to June 2014 was studied using ground gravimetry combined with vertical displacement data from the Global Navigation Satellite System.Results show that observed gravity variation in this area increased continuously,basically reflecting a trend toward land subsidence.With the effect of this subsidence removed,a dominantnegative change in gravity variation was evident,reflecting an average rate of decrease in terrestrial water in this area of 0.10±0.053 m/y,and this is equivalent to a volume of 81.5±43.2×108 m^(3)and is consistent with the spatial distribution of groundwater change from measured hydrologic data.These results can be an essential reference and supplement for the study of terrestrial water variation in the Hebei plain area,and indicate that ground surface gravimetry can be used as an important mean for studying changes in terrestrial water.Hongtao Hao Hongliang Liu Xinlin Zhang Jin Wei Bin Zhao Minzhang Hu 2021Geodesy and Geodynamics2021,12,3:1
