| 1 | Research on solar aided coal-fired power generation system and performance analysis显示文摘Integrating solar power utilization systems with coal-fired power units, the solar aided coal-fired power generation (SACPG) shows a significant prospect for the large-scale utilization of solar energy and energy saving of thermal power units. The methods and mechanism of system integration were studied. The parabolic trough solar collectors were used to collect solar energy and the integration scheme of SACPG system was determined considering the matching of working fluid flows and energy flows. The thermodynamic characteristics of solar thermal power generation and their effects on the performance of thermal power units were studied, and based on this the integration and optimization model of system structure and parameters were built up. The integration rules and coupling mecha- nism of SACPG systems were summarized in accordance with simulation results. The economic analysis of this SACPG system showed that the solar LEC of a typical SACPG system, considering CO2 avoidance, is 0.098 $/kW·h, lower than that of SEGS, 0.14 $/kW·h. | YANG YongPing CUI YingHong HOU HongJuan GUO XiYan YANG ZhiPing WANG NinLing | 2008 | Science China(Technological Sciences)2008，51，8： | 30 |

| 3 | Preparation and luminescence characteristics of Sr_3SiO_5:Eu^(2+) phosphor for white LED显示文摘The Sr3SiO5:Eu2+ phosphor was synthesized by high temperature solid-state reaction. The emission spectrum of Sr3SiO5:Eu2+ shows two bands centered at 487 and 575 nm, which well agree with the theoretic values of emission spectrum. The excitation spectrum for 575 nm emission center has several excitation bands at 365, 418, 458 and 473 nm. And the results show that the emission spectrum of Sr3SiO5:Eu2+ is influenced by the Eu2+ concentration. The relative emission spectra of the white-emitting InGaN-based YAG:Ce3+ LED and Sr3SiO5:Eu2+ LED were investigated. The results show that the color development of InGaN-based Sr3SiO5:Eu2+ is better than that of InGaN-based YAG:Ce3+, and the CIE chromaticity of InGaN-based Sr3SiO5:Eu2+ is (x=0.348, y=0.326). | LI PanLai YANG ZhiPing WANG ZhiJun GUO QingLin LI Xu | 2008 | Chinese Science Bulletin2008，53，7： | 16 |
| 4 | Fouling corrosion in aluminum heat exchangers显示文摘Fouling deposits on aluminum heat exchanger reduce the heat transfer efficiency and cause corrosion to the apparatus.This study focuses on the corrosive behavior of aluminum coupons covered with a layer of artificial fouling in a humid atmosphere by their weight loss,Tafel plots,electrochemical impedance spectroscopy(EIS),and scanning electron microscope(SEM)observations.The results reveal that chloride is one of the major elements found in the fouling which damages the passive film and initiates corrosion.The galvanic corrosion between the metal and the adjacent carbon particles accelerates the corrosive process.Furthermore,the black carbon favors the moisture uptake,and gives the dissolved oxygen greater chance to migrate through the fouling layer and form a continuous diffusive path.The corrosion rate decreasing over time is conformed to electrochemistry measurements and can be verified by Faraday’s law.The EIS results indicate that the mechanism of corrosion can be interpreted by the pitting corrosion evolution mechanism,and that pitting was observed on the coupons by SEM after corrosive exposure. | Su Jingxin Ma Minyu Wang Tianjing Guo Xiaomei Hou Liguo Wang Zhiping | 2015 | Chinese Journal of Aeronautics2015，28，3： | 5 |
| 5 | Post-fledging dispersal and habitat use of a reintroduced population of the Crested Ibis (Nipponia nippon)显示文摘Background: Knowledge of dispersal movement of birds and their habitat preference during the post-fledging period is fundamental to the understanding of their ecological and evolutionary processes. The Crested Ibis is now being reintroduced to protected sites within its historical range, with the goal of establishing a self-sustaining population that may eventually qualify the species for delisting.Methods: We carried out an ecological study of post-fledging dispersal and habitat use of a reintroduced population of the Crested Ibis(Nipponia nippon) from 2008 to 2012 in Ningshan County, China, by using banding and radio-telemetry methods.Results: In about two weeks(an average of 14.3 days) after fledging, the activities of the fledglings were concentrated in a range of about 100 m around their natal sites, such as the oak-pine forest patches at the edge of open habitats.During this period, fledglings were still partially dependent upon parental care and fed typically on a daily basis.Siblings increasingly became independent by mid-August and then gradually moved away from their natal sites to post-fledging dispersal locations. During the period of the post-fledging dispersal process, most juveniles moving southwest were concentrated at the mean direction(μ = 254.6°, ? = 70.5°) with a mean dispersal distance of 5.1 km.It took an average of 56.4 days to disperse from the natal territory to the first wintering area. Also, forging habitats for juvenile ibis varied with time and local conditions. For example, paddy fields were used most frequently among all habitat types, while shallow rivers just from August to October. Masson pine(Pinus massoniana) was often regarded as the roosting tree species preferred by the Crested Ibis, with the highest utilization rate among all the roosting habitat types. The juveniles of the wild population dispersed four times as far as that of the reintroduced population, but the overall pattern of post-fledging dispersal is similar for the reintroduced and wild populations.Conclusions: Our results are very useful for us to predict the distance and direction of dispersal under various landscape conditions in other released sites. The project is a good example for reintroducing endangered species to their former ranges, and will be valuable for the protection of reintroduced populations of this critically and other endangered species. | Zhiping Huo Junfeng Guo Xia Li Xiaoping Yu | 2014 | Chinese Birds2014，，1： | 4 |
| 6 | Spatial learning and memory deficits in young adult mice exposed to a brief intense noise at postnatal age显示文摘Noise pollution is a major hazardous factor to human health and is likely harmful for vulnerable groups such as pre-term infants under lifesupport system in an intensive care unit. Previous studies have suggested that noise exposure impairs children's learning ability and cognitive performance and cognitive functions in animal models in which the effect is mainly attributed to the oxidant stress of noise on the cognitive brain. The potential role of noise induced hearing loss(NIHL), rather than the oxidant stress, has also been indicated by a depression of neurogenesis in the hippocampus long after a brief noise exposure, which produces only a tentative oxidant stress. It is not clear if noise exposure and NIHL during early development exerts a long term impact on cognitive function and neurogenesis towards adulthood. In the present study, a brief noise exposure at high sound level was performed in neonatal C57BL/6J mice(15 days after birth) to produce a significant amount of permanent hearing loss as proved 2 months after the noise. At this age, the noise-exposed animals showed deteriorated spatial learning and memory abilities and a reduction of hippocampal neurogenesis as compared with the control. The averaged hearing threshold was found to be strongly correlated with the scores for spatial learning and memory. We consider the effects observed are largely due to the loss of hearing sensitivity, rather than the oxidant stress, due to the long interval between noise exposure and the observations. | Shan Tao Lijie Liu Lijuan Shi Xiaowei Li Pei Shen Qingying Xun Xiaojing Guo Zhiping Yu Jian Wang | 2015 | Journal of Otology2015，10，1： | 3 |
| 7 | A bone-targeted engineered exosome platform delivering siRNA to treat osteoporosis显示文摘The complex pathogenesis of osteoporosis includes excessive bone resorption,insufficient bone formation and inadequate vascularization,a combination which is difficult to completely address with conventional therapies.Engineered exosomes carrying curative molecules show promise as alternative osteoporosis therapies,but depend on specifically-functionalized vesicles and appropriate engineering strategies.Here,we developed an exosome delivery system based on exosomes secreted by mesenchymal stem cells(MSCs)derived from human induced pluripotent stem cells(iPSCs).The engineered exosomes BT-Exo-siShn3,took advantage of the intrinsic anti-osteoporosis function of these special MSC-derived exosomes and collaborated with the loaded siRNA of the Shn3 gene to enhance the therapeutic effects.Modification of a bone-targeting peptide endowed the BT-Exo-siShn3 an ability to deliver siRNA to osteoblasts specifically.Silencing of the osteoblastic Shn3 gene enhanced osteogenic differentiation,decreased autologous RANKL expression and thereby inhibited osteoclast formation.Furthermore,Shn3 gene silencing increased production of SLIT3 and consequently facilitated vascularization,especially formation of type H vessels.Our study demonstrated that BT-Exo-siShn3 could serve as a promising therapy to kill three birds with one stone and implement comprehensive anti-osteoporosis effects. | Yongzhi Cui Yuanyuan Guo Li Kong Jingyu Shi Ping Liu Rui Li Yongtao Geng Weihang Gao Zhiping Zhang Dehao Fu | 2022 | Bioactive Materials2022，7，4： | 3 |
| 8 | Grid Model for High-accuracy Coordinate Transformation of China Geodetic Coordinate System 2000显示文摘After implementing CGCS2000,establishing grid models for high-accuracy coordinate transformation which are mainly used to transform border lines and coordinate grids of topographic maps becomes an important issue in mapping applications.Consequently,a grid model for high-accuracy coordinate transformation of CGCS2000 is proposed.Specifically,we firstly analyze a minimum curvature equation of coordinate transformation,which possesses the characteristics of both the global and local smoothness,achieving better consistency with the consecutive smoothness for the coordinate transformation of map’s linear feature.Then an iterative calculation method of grid nodes and an approach for establishing regional grid models based on collocation by two-step minimization are proposed.Meanwhile,a data structure of grid model is constructed.Finally we give the optimized grid interval and transformation accuracy in China corresponding to the proposed grid model.Using 48 433 points of 2000 National Geodetic Control Network of China,we take the proposed model into practice by constructing grid models for coordinate transformation from BJS54 and XAS80 to CGCS2000,and the external positional accuracies for both models are 0.26 m and 0.03 m respectively. | Zhiping LU Ziqing WEI Jun LI Chong GUO | 2019 | Journal of Geodesy and Geoinformation Science2019，2，1： | 3 |
| 9 | Wind Tunnel Experiments and Numerical Study on Performance Characteristics of an H-type Vertical Axis Wind Turbine in the Spanwise Direction显示文摘The aerodynamic forces and vortex characteristics of an H-type Vertical Axis Wind Turbine(VAWT)become complicated because of dynamic stall,particularly in the three-dimensional impact on the blade spanwise direction.This study focused on the evaluation of the aerodynamic performance and vortex characteristics of an H-type VAWT in the spanwise direction by numerical simulations and wind tunnel experiments.Pressure acting on the blade surface was obtained from multiport pressure measurement devices by wind tunnel.Meanwhile,the vortex field around different blade sections was investigated through numerical simulations.The stall behavior was analysed by comparing the results of numerical simulations and experiments.As a result,the tangential force of single blade was mainly contributed at the chordwise position of x/c≤0.4 c and the power of single blade was mainly contributed at the azimuthal angle range of 60°≤θ≤150°in the blade section position region of 0≤z/(H/2)≤0.7.At the section position of z/(H/2)=0.5,the initial flow separation was found at the suction side and progressed forward to the leading edge.With the increase of the tip speed ratios,the decreasing position of the averaged local power coefficient of each section was closer to the middle section of z/(H/2)=0,and the attenuation speed became faster.The power coefficient reductions at the blade section position of z/(H/2)=0.9 were 38.29%,46.78%and 56.42%when the tip speed ratios were 1.38,2.19 and 2.58,respectively.The results of this study provided a better understanding of the development of the performance characteristics and vortex characteristics of H-type VAWT. | ZHANG Yanfeng LI Qing’an ZHU Xinyu SONG Xiaowen CAI Chang GUO Zhiping | 2021 | Journal of Thermal Science2021，30，3： | 2 |

| 12 | Preparation of enzymatically cross-linked sulfated chitosan hydrogel and its potential application in thick tissue engineering显示文摘For the requirement of preliminary vascularization,the scaffolds for thick tissue engineering should have not only good cell affinity,but also anticoagulant ability.In this paper,enzymatically cross-linked hydrogel scaffolds based on sulfated chitosan(SCTS)were prepared.Firstly,sulfated chitosan-hydroxyphenylpionic acid(SCTS-HPA)conjugate was synthesized,and the structure of SCTS-HPA was identified by FITR and1H NMR.And then the enzymatically cross-linked hydrogels were prepared in presence of horseradish peroxidase(HRP)and hydrogen peroxide(H2O2).The gelation time,mechanical property,morphology and cytotoxicity to human umbilical vein endothelial cells(HUVECs)of the hydrogel were evaluated in vitro,the tissue compatibility of SCTS-HPA scaffold was studied in vivo.The results showed that the gelation time,mechanical property,morphology of the dehydrated hydrogel could be controlled by the the concentration of HRP and H2O2.The cytotoxicity test showed that the hydrogel extracts have no cytotoxicity to HUVECs.The in vivo assay indicated that SCTS-HPA scaffold have good tissue compatibility with no thrombus formation.All these results indicated that the SCTS-HPA scaffold could be used as a thick tissue engineering scaffold. | CHEN ZhiPing WANG Wei GUO Lei YU YanYan YUAN Zhi | 2013 | Science China Chemistry2013，56，12： | 2 |
| 13 | Visible Raman and Brillouin lasers from a microresonator/ZBLAN-fiber hybrid system显示文摘Raman and Brillouin lasers based on a high-quality(high-Q) whispering gallery mode microresonator(WGMR)are usually achieved by employing a tunable single-frequency laser as a pump source. Here, we experimentally demonstrate visible Raman and Brillouin lasers using a compact microresonator/ZrF4-BaF2-LaF3-AlF3-NaF(ZBLAN)-fiber hybrid system by incorporating a WGMR with a fiber-compatible distributed Bragg reflector/fiber Bragg grating to form a Fabry–Perot(F-P) fiber cavity and using a piece of Pr:ZBLAN fiber as gain medium.The high-Q silica-microsphere not only offers a Rayleigh-scattering-induced backreflection to form the ~635 nm red laser oscillation in the F-P fiber cavity, but also provides a nonlinear gain in the WGMR itself to generate either stimulated Raman scattering or stimulated Brillouin scattering. Up to six-order cascaded Raman lasers at0.65 μm, 0.67 μm, 0.69 μm, 0.71 μm, 0.73 μm, and 0.76 μm are achieved, respectively. Moreover, a Brillouin laser at 635.54 nm is clearly observed. This is, to the best of our knowledge, the first demonstration of visible microresonator-based lasers created by combining a Pr:ZBLAN fiber. This structure can effectively extend the laser wavelength in the WGMR to the visible waveband and may find potential applications in underwater communication, biomedical diagnosis, microwave generation, and spectroscopy. | SHUISEN JIANG CHANGLEI GUO KAIJUN CHE ZHENGQIAN LUO TUANJIE DU HONGYAN FU HUIYING XU ZHIPING CAI | 2019 | Photonics Research2019，7，5： | 1 |

| 17 | Impact analysis of human factors on power system operation reliability显示文摘Along with the improvement of electrical equipment reliability,people’s unsafe behaviors and human errors have become one of main sources of risks in power systems.However,there is no comprehensive study on human factors and human reliability analysis in power systems.In allusion to this situation,this paper attempts to analyze the impact of human factors on power system reliability.First,this paper introduces current situation of human factors in power systems and the latest research progress in this field.Several analysis methods are proposed according to specified situations,and these methods are verified by some power system practical cases.On this base,this paper illustrates how human factors affect power system operation reliability from 2 typical aspects:imperfect maintenance caused by human errors,and impact of human factors on emergency dispatch operation and power system cascading failure.Finally,based on information decision and action in crew(IDAC),a novel dispatcher training evaluation simulation system(DTESS)is established,which can incorporate all influencing factors.Once fully developed,DTESS can be used to simulate dispatchers’response when encountering an initial event,and improve power system dispatching reliability. | Yingkai BAO Chuangxin GUO Jinjiang ZHANG Jiaxin WU Suhong PANG Zhiping ZHANG | 2018 | Journal of Modern Power Systems and Clean Energy2018，6，1： | 1 |
