| 1 | Dynamic Performance of High Speed Solenoid Valve with Parallel Coils显示文摘The methods of improving the dynamic performance of high speed on/off solenoid valve include increasing the magnetic force of armature and the slew rate of coil current, decreasing the mass and stroke of moving parts. The increase of magnetic force usually leads to the decrease of current slew rate, which could increase the delay time of the dynamic response of solenoid valve. Using a high voltage to drive coil can solve this contradiction, but a high driving voltage can also lead to more cost and a decrease of safety and reliability. In this paper, a new scheme of parallel coils is investigated, in which the single coil of solenoid is replaced by parallel coils with same ampere turns. Based on the mathematic model of high speed solenoid valve, the theoretical formula for the delay time of solenoid valve is deduced. Both the theoretical analysis and the dynamic simulation show that the effect of dividing a single coil into N parallel sub-coils is close to that of driving the single coil with N times of the original driving voltage as far as the delay time of solenoid valve is concerned. A specific test bench is designed to measure the dynamic performance of high speed on/off solenoid valve. The experimental results also prove that both the delay time and switching time of the solenoid valves can be decreased greatly by adopting the parallel coil scheme. This research presents a simple and practical method to improve the dynamic performance of high speed on/off solenoid valve. | KONG Xiaowu LI Shizhen | 2014 | Chinese Journal of Mechanical Engineering2014，27，4： | 13 |
| 2 | Improved Brassica rapa reference genome by single-molecule sequencing and chromosome conformation capture technologies显示文摘Brassica rapa comprises several important cultivated vegetables and oil crops.Current reference genome assemblies of Brassica rapa are quite fragmented and not highly contiguous,thereby limiting extensive genetic and genomic analyses.Here,we report an improved assembly of the B.rapa genome(v3.0)using single-molecule sequencing,optical mapping,and chromosome conformation capture technologies(Hi-C).Relative to the previous reference genomes,our assembly features a contig N50 size of 1.45 Mb,representing a~30-fold improvement.We also identified a new event that occurred in the B.rapa genome~1.2 million years ago,when a long terminal repeat retrotransposon(LTR-RT)expanded.Further analysis refined the relationship of genome blocks and accurately located the centromeres in the B.rapa genome.The B.rapa genome v3.0 will serve as an important community resource for future genetic and genomic studies in B.rapa.This resource will facilitate breeding efforts in B.rapa,as well as comparative genomic analysis with other Brassica species. | Lei Zhang Xu Cai Jian Wu Min Liu Stefan Grob Feng Cheng Jianli Liang Chengcheng Cai Zhiyuan Liu Bo Liu Fan Wang Song Li Fuyan Liu Xuming Li Lin Cheng Wencai Yang Mai-he Li Ueli Grossniklaus Hongkun Zheng Xiaowu Wang | 2018 | Horticulture Research2018，5，1： | 10 |
| 3 | A de novo Genome of a Chinese Radish Cultivar显示文摘Here, we report a high-quality draft genome of a Chinese radish(Raphanus sativus) cultivar.

By comparative analyses of the radish genome against 10 other plant genomes, 2 275 genes in 780 gene families were found unique to R. sativus. This genome is a good reference for genomic study and of great value for genetic improvement of radish. | ZHANG Xiaohui YUE Zhen MEI Shiyong QIU Yang YANG Xinhua CHEN Xiaohua CHENG Feng WU Zhangyan SUN Yuyan JING Yi LIU Bo SHEN Di WANG Haiping CUI Na DUAN Yundan WU Jian WANG Jinglei GAN Caixia WANG Jun WANG Xiaowu LI Xixiang | 2015 | Horticultural Plant Journal2015，1，3： | 10 |
| 4 | Identification of QTLs and Validation of qCd-2 Associated with Grain Cadmium Concentrations in Rice显示文摘Cadmium(Cd) is one of heavy metals harmful to human health. As rice is the main staple food in Asia and Cd is easily contaminated in rice, the molecular regulation of Cd accumulation should be explored. In this study, a recombinant inbred population derived from Xiang 743/Katy was grown in Cd-polluted fields and used to map the quantitative trait loci(QTLs) for Cd accumulation in rice grains. We identified seven QTLs distributed on chromosomes 2, 3, 6, 7, 8 and 10. These QTLs displayed phenotypic variances of 58.50% and 40.59% in 2014 and 2015, respectively. Two QTLs, qCd-2 and qCd-7, were identified in both the two years. qCd-2 was detected on the interval of RM250–RM207 on chromosome 2, with an LOD of 2.51 and a phenotypic contribution of 13.75% in 2014, and an LOD of 3.35 and a phenotypic contribution of 14.16% in 2015. qCd-7 co-localized with the cloned qCdT7 on chromosome 7 and may represent the correct candidate. The other five QTLs were detected only in one year. To further confirm the effects of qCd-2, a residual heterozygous line designated as RHL945, with a heterozygous interval of RM263–RM207 on chromosome 2, was selected from the recombinant inbred population and used to develop an F2 population consisting of 155 individual plants. By incorporating further simple sequence repeat markers into the segmental linkage map of the target region, qCd-2 was delimited in the interval of RM5404–RM3774, with an LOD value of 4.38 and a phenotypic contribution of 15.52%. These results reflected the genetic regulation of grain Cd in rice and paved the way for the future cloning of qCd-2. | LIU Wenqiang PAN Xiaowu LI Yongchao DUAN Yonghong MIN Jun LIU Sanxiong LIU Licheng SHENG Xinnian LI Xiaoxiang | 2019 | Rice science2019，26，1： | 6 |

| 6 | Video motion stitching using trajectory and position similarities显示文摘Stitching motions in multiple videos into a single video scene is a challenging task in current video fusion and mosaicing research and film production. In this paper, we present a novel method of video motion stitching based on the similarities of trajectory and position of foreground objects. First, multiple video sequences are registered in a common reference frame, whereby we estimate the static and dynamic backgrounds, with the former responsible for distinguishing the foreground from the background and the static region from the dynamic region, and the latter functioning in mosaicing the warped input video sequences into a panoramic video. Accordingly, the motion similarity is calculated by reference to trajectory and position similarity, whereby the corresponding motion parts are extracted from multiple video sequences. Finally, using the corresponding motion parts, the foregrounds of different videos and dynamic backgrounds are fused into a single video scene through Poisson editing, with the motions involved being stitched together. Our major contributions are a framework of multiple video mosaicing based on motion similarity and a method of calculating motion similarity from the trajectory similarity and the position similarity. Experiments on everyday videos show that the agreement of trajectory and position similarities with the real motion similarity plays a decisive role in determining whether two motions can be stitched. We acquire satisfactory results for motion stitching and video mosaicing. | CHEN XiaoWu LI Qing LI Xin ZHAO QinPing | 2012 | Science China(Information Sciences)2012，55，3： | 4 |
| 7 | Microstructure evolution of directionally solidifi ed Sn-16%Sb hyperperitectic alloy显示文摘The directionally solidifi ed microstructure of Sn-16%Sb hyperperitectic alloy has been investigated at various solidifi cation rates using a high-thermal gradient directional solidif ication apparatus. The results indicate that the solidifi cation microstructure consists of hard primary intermetallic SnSb phase embedded in a matrix of soft peritectic β-Sn phase. The primary SnSb phase exhibits faceted growth with tetragonal or trigonal shapes. At the same time, the primary SnSb phase is ref ined with an increase in the solidif ication rate and dispersed more uniformly in the matrix of β-Sn phase. The volume fraction of the SnSb phase fi rstly decreases and then increases when the solidif ication rate increases in directional solidif ication of Sn-16%Sb hyperperitectic alloy. | Hu Xiaowu Li Shuangming Liu Lin Fu Hengzhi | 2008 | China Foundry2008，5，3： | 4 |
| 8 | Selective recovery of lithium from simulated brine using different organic synergist显示文摘The organic synergists, including Octanol, ethyl acetate(EA), butyl acetate(BA), methyl isobutyl ketone(MIBK),diisobutyl ketone(DIBK), N,N-bis(2-ethylhexyl) acetamide(N523) and 8-hydroxylquiolate, were added to the TBP–FeCl_3 extraction system to extract lithium from brine. The effects of concentration of organic synergist and total organic extractant, molar ratio of Fe/Li, phase ratio, counter-current extraction and the acidity of stripping agent on lithium extraction were investigated to optimize the extraction conditions. Under the optimize conditions, the results of counter-current extraction showed the mixed extraction system was the preponderance on the lithium extraction. Especially the separation of lithium in organic phase and aqueous phase and the separation mass ratio of Mg/Li increased greatly. An extraction mechanism was proposed based on the analysis of FT-IR spectra and Raman spectra. | Huifang Li Lijuan Li Xiaowu Peng Lianmin Ji Wu Li | 2019 | Chinese Journal of Chemical Engineering2019，27，2： | 4 |

| 11 | Large piezoelectric response in a family of metal-free perovskite ferroelectric compounds from first-principles calculations显示文摘Metal-free organic perovskite ferroelectric materials have been shown recently to have a number of attractive properties,including high spontaneous polarization and piezoelectric coefficients.In particular,slow evaporation of solutions containing organic amines,inorganic ammoniums,and dilute hydrohalogen acid has been shown to produce several attractive materials in the MDABCO-NH_(4)-I_(3) family(MDABCO is N-methyl-N’-diazabicyclo[2,2,2]octonium).In the present work,we study by first-principles calculations the origin of polarizaiton,electronic density of state,piezoelectric response,and elastic properties of MDABCO-NH_(4)-X_(3)(X=Cl,Br,I).We find that the dipole moments of the MDABCO and NH_(4) groups are negligible,and the large spontaneous polarization of MDABCONH_(4)-I_(3) mainly results from MDABCO and NH_(4) being off-center relative to I ions.Although the piezoelectric response of organic materials is usually very weak,we observe large piezoelectric strain components,d_(x4) and d_(x5);the calculated d_(x5) is 119 pC/N for MDABCO-NH_(4)-Cl_(3),248 pC/N for MDABCO-NH_(4)-Br_(3) and 178 pC/N for MDABCO-NH_(4)-I_(3).The large value of dx5 is found to be closely related with the large value of elastic compliance tensor,s44.These results show that MDABCO-NH_(4)-X_(3) metal-free organic perovskites have large piezoelectric response with soft elastic properties. | Hui Wang Huihui Liu Zeyu Zhang Zihan Liu Zhenlong Lv Tongwei Li Weiwei Ju Haisheng Li Xiaowu Cai Han Han | 2019 | npj Computational Materials2019，，1： | 3 |
| 12 | Microstructural Characterization and Hardness Behavior of a Biological Saxidomus purpuratus Shell显示文摘The microstructures of the Saxidomus purpuratus shell were observed.It was found that the inner and middle layers of the shell are composed of crossed lamellae,while the outer layer exhibits porous structures.With the characteristic structure of each layer,the hardness of inner layer with narrow domains in crossed lamellar structure is the highest,and that of middle layer with wide domains is lower,while the outer layer has the lowest hardness.The damage morphologies of the indentations change a lot,depending not only upon the magnitude of the indentation load,but also upon the orientation between the indentation direction and the crossed lamellae in the microstructure of the shell,which illustrates the anisotropy in mechanical properties of such shells. | Wen Yang Guangping Zhang Huasai Liu Xiaowu Li | 2011 | Journal of Materials Science & Technology2011，27，2： | 3 |

| 15 | Effect of sample diameter on primary and secondary dendrite arm spacings during directional solidification of Pb-26wt.%Bi hypo-peritectic alloy显示文摘The microstructure scales of dendrites,such as primary and secondary dendrite arm spacings,control the segregation profiles and the formation of secondary phases within interdendritic regions,which determine the properties of solidified structures.Investigations on primary and secondary dendrite arm spacings of primary α-phase during directionally solidified Pb-26wt%Bi hypo-peritectic alloy were carried out in this research,and systematic studies were conducted using cylindrical samples with different diameters(Φ = 1.8 and 7.0 mm) in order to analyze the effects of sample diameter on the primary and secondary dendrite arm spacings.In this work,the dependence of dendrite arm spacings on growth velocity was established.In addition,the experimental data concerning the primary and secondary dendrite arm spacings were compared with the main predictive dendritic models from the literatures.A comparison between experimental results for dendrite arm spacings of the 1.8-mm-diameter sample and 7.0-mm-diameter sample was also conducted. | HU Xiaowu YAN Hong CHEN Wenjing LI Shuangming FU Hengzhi | 2011 | Rare Metals2011，30，4： | 2 |

| 17 | Optimization of Grain Boundary Character Distribution in Fe-18Cr-18Mn-0.63N High-Nitrogen Austenitic Stainless Steel显示文摘Grain boundary engineering(GBE)is a practice of improving resistance to grain boundary failure of the material through increasing the proportion of low Σ coincidence site lattice(CSL)grain boundaries(special grain boundaries)in the grain boundary character distribution(GBCD).The GBCD in a cold rolled and annealed Fe-18Cr-18Mn-0.63N high-nitrogen austenitic stainless steel was analyzed by electron back scatter difraction(EBSD).The results show that the optimization process of GBE in the conventional austenitic stainless steel cannot be well applied to this high-nitrogen austenitic stainless steel.The percentage of lowΣCSL grain boundaries could increase from 47.3%for the solid solution treated high-nitrogen austenitic stainless steel specimen to 82.0%for the specimen after 5%cold rolling reduction and then annealing at 1423 K for 10 min.These special boundaries of high proportion efectively interrupt the connectivity of conventional high angle grain boundary network and thus achieve the GBCD optimization for the high-nitrogen austenitic stainless steel. | Feng SHI Xiaowu LI Yutong HU Chuan SU Chunming LIU | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，5： | 2 |

| 20 | Single-event burnout hardening of planar power MOSFET with partially widened trench source显示文摘We present a single-event burnout(SEB) hardened planar power MOSFET with partially widened trench sources by three-dimensional(3 D) numerical simulation. The advantage of the proposed structure is that the work of the parasitic bipolar transistor inherited in the power MOSFET is suppressed effectively due to the elimination of the most sensitive region(P-well region below the N+ source). The simulation result shows that the proposed structure can enhance the SEB survivability significantly. The critical value of linear energy transfer(LET),which indicates the maximum deposited energy on the device without SEB behavior, increases from 0.06 to0.7 p C/μm. The SEB threshold voltage increases to 120 V, which is 80% of the rated breakdown voltage. Meanwhile, the main parameter characteristics of the proposed structure remain similar with those of the conventional planar structure. Therefore, this structure offers a potential optimization path to planar power MOSFET with high SEB survivability for space and atmospheric applications. | Jiang Lu Hainan Liu Xiaowu Cai Jiajun Luo Bo Li Binhong Li Lixin Wang Zhengsheng Han | 2018 | Journal of Semiconductors2018，39，3： | 1 |
