| 1 | From concept to reality-A review to the primary test stand and its preliminary application in high energy density physics显示文摘Pulsed power technology,whereas the electrical energy stored in a relative long period is released in much shorter timescale,is an efficient method to create high energy density physics(HEDP)conditions in laboratory.Around the beginning of this century,China Academy of Engineering Physics(CAEP)began to build some experimental facilities for HEDP investigations,among which the Primary Test Stand(PTS),a multi-module pulsed power facility with a nominal current of 10 MA and a current rising time~90 ns,is an important achievement on the roadmap of the electro-magnetically driven inertial confinement fusion(ICF)researches.PTS is the first pulsed power facility beyond 10 TW in China.Therefore,all the technologies have to be demonstrated,and all the engineering issues have to be overcome.In this article,the research outline,key technologies and the preliminary HEDP experiments are reviewed.Prospects on HEDP research on PTS and pulsed power development for the next step are also discussed. | Jianjun Deng Weiping Xie Shuping Feng Meng Wang Hongtao Li Shengyi Song Minghe Xia Ji Ce An He Qing Tian Yuanchao Gu Yongchao Guan Bin Wei Xianbin Huang Xiaodong Ren Jiakun Dan Jing Li Shaotong Zhou Hongchun Cai Siqun Zhang Kunlun Wang Qiang Xu Yujuan Wang Zhaohui Zhang Guilin Wang Shuai Guo Yi He Yiwei Zhou Zhanji Zhang Libing Yang Wenkang Zou | 2016 | Matter and Radiation at Extremes2016，1，1： | 19 |
| 2 | Mutation of the PHYTOENE DESATURASE 3 gene causes yellowish-white petals in Brassica napus显示文摘Oilseed rape (Brassica napus) with yellow flowers is an attractive ornamental landscape plant during the flowering period,and the development of different petal colors has become a breeding objective.Although yellowish flower color is a common variant observed in field-grown oilseed rape,the genetics behind this variation remains unclear.We obtained a yellowish-white flower (ywf) mutant from Zhongshuang 9 (ZS9) by ethyl methanesulfonate mutagenesis (EMS) treatment.Compared with ZS9,ywf exhibited a lower carotenoid content with a reduced and defective chromoplast ultrastructure in the petals.Genetic analysis revealed that the yellowish-white trait was controlled by a single recessive gene.Using bulked-segregant analysis sequencing (BSA-seq) and kompetitive allele-specific PCR(KASP),we performed map-based cloning of the ywf locus on chromosome A08 and found that ywf harbored a C-to-T substitution in the coding region,resulting in a premature translation termination.YWF,encoding phytoene desaturase 3 (PDS3),was highly expressed in oilseed rape petals and involved in carotenoid biosynthesis.Pathway enrichment analysis of the transcriptome profiles from ZS9 and ywf indicated the carotenoid biosynthesis pathway to be highly enriched.Further analyses of differentially expressed genes and carotenoid components revealed that the truncated Bna A08.PDS3 resulted in decreased carotenoid biosynthesis in the mutant.These results contribute to an understanding of the carotenoid biosynthesis pathway and manipulation of flower-color variation in B.napus. | Chuanji Zhao Luqman Bin Safdar Meili Xie Meijuan Shi Zhixue Dong Li Yang Xiaohui Cheng Yueying Liu Zetao Bai Yang Xiang Chaobo Tong Junyan Huang Lijiang Liu Shengyi Liu | 2021 | The Crop Journal2021，9，5： | 3 |
| 3 | Stitching algorithm for ion beam figuring of optical mirrors显示文摘A novel stitching machining method for ion beam figuring of optical mirrors is presented in this paper. Problems that should be dealt with in the stitching process such as shaping principle,algorithm for dwell time calculation,parameter identification and compensation for positioning errors are discussed. Based on Computer Controlled Optical Surfacing(CCOS)principle,the finite field nonlinear model is deduced from the stitching shaping mechanism;with the superposition property in the model,a modified Richardson-Lucy iterative algorithm is presented to deconvolute the dwell time for the stitching process;the effect of the positioning errors and the removal rate on the machining accuracy and shape is modeled and then the identification and compensation algorithm for these parameters is proposed based on this model.With these studies,shaping theory and algorithm are constructed,and then the stitching process for ion beam figuring comes into being.Figuring experiments are made on planar samples;the process convergence ratio is 10,which is similar to that in full aperture figuring.Theo- retical and experimental studies indicate that the stitching theory and algorithm in the ion beam figuring process presented in this paper are a novel method for fabrication of precision mirrors with lower cost. | ShengYi Li ChangJun Jiao XuHui Xie Lin Zhou | 2009 | Science China(Technological Sciences)2009，52，12： | 3 |
| 4 | Achyranthes bidentata polysaccharide can safely prevent NSCLC metastasis via targeting EGFR and EMT显示文摘Dear Editor,Cancer metastasis,dissemination of cancer cells from primary tumors to distant sites,attributes to 90%cancer-related death.1 Although the targeted therapies,bio-nanomaterial-based target delivery,and the consequent adoption of the so-called personalized medicine have obtained notable achievements in some cancers,significant problems still exist with these approaches.2 There are hardly any cancer therapeutic agents that can interfere with metastasized cancer.In recent times,we proposed a novel concept,namely cancer metastasis chemoprevention,which is different from the existing cancer chemotherapy and cancer chemoprevention.Cancer metastasis chemoprevention aims at safely preventing circulating tumor cells(CTCs)and related molecules from gemmating into the metastatic tissues.The strategy does not intend to kill cancer cells as cancer chemotherapy does,nor to aimlessly prevent cancers from carcinogenesis as cancer chemoprevention does. | Chunlian Zhong Jingyi Yang Yusheng Lu Huanzhang Xie Shengyi Zhai Chen Zhang Zhiying Luo Xuanchen Chen Xuanmo Fang Lee Jia | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 3 |
| 5 | Frequency-domain analysis of computer-controlled optical surfacing processes显示文摘Mid-high spatial frequency errors are often induced on optical surfaces polished by computer-controlled optical surfacing (CCOS) processes. In order to efficiently remove these errors, which would degrade the performances of optical systems, the ability of a CCOS process to correct the errors have been investigated based on the convolution integral model in view of the availability of material removal. To quantify the ability, some conceptions, such as figure correcting ability and material removal availability (MRA), have been proposed. The research result reveals that the MRA of the CCOS process to correct a single spatial frequency error is determined by its tool removal function (TRF), and it equals the normalized amplitude spectrum of the Fourier transform of its TRF. Finally, three sine surfaces were etched using ion beam figuring (IBF), which is a typical CCOS process. The experimental results have verified the theoretical analysis. The employed method and the conclusions of this work provide a useful mathematical basis to analyze and optimize CCOS processes. | ZHOU Lin DAI YiFan XIE XuHui LI ShengYi | 2009 | Science China(Technological Sciences)2009，52，7： | 2 |
| 6 | Design and Characterization of a Novel Z-axis Quartz Cross-fork Micromachined Gyroscope显示文摘The existing researches on quartz gyroscope mainly focus on the structure design of the tuning fork, which aim at obtaining a better vibration characterization. However, the fabrication of complicated structure is a challenge for present processes, and the imperfect fabrication process seriously affects the performances of the sensors. In this paper, a novel quartz cross-fork structure micromachined gyroscope is proposed. The sensor has a simple structure in x-y plane of quartz crystal. Unlike other quartz gyroscopes, the proposed gyroscope is based on shear stress detection to sense Coriolis' force rather than normal stress detection. This feature can simplify the sensing electrode patterns and miniaturize the structure easily. Then the mechanical analysis of the structure is discussed. In order to obtain high sensitivities and uniform characteristics between different structures, the sensing beam is designed to be tapered, and the taper should be appreciably greater than 1°. This scheme is validated by finite element analysis software. The dynamic characteristic of the structure is analyzed by lumped parameter model. The dynamic stress in the beam and the detection sensitivity are deduced to optimize the structure parameter of gyroscope. Finally, the gyroscope is fabricated by quartz anisotropic wet etching. The prototype is characterized as follows. The drive mode frequency is 13.38 kHz, and the quality factor is about 900 in air. The scale factor is 1.45 mV/((°) s -1 ) and the nonlinearity is 3.6% in the dynamic range of ±200°/s. Process and test results show that the proposed quartz gyroscope can achieve a high performance at atmosphere pressure. The research can simplify the fabrication of the quartz gyroscope, and is taken as a novel method for the design of quartz gyroscope. | XIE Liqiang WU Xuezhong LI Shengyi WANG Haoxu TAO Yi DONG Peitao | 2011 | Chinese Journal of Mechanical Engineering2011，24，1： | 2 |
