| 1 | Design and test of soft-pot-tray automatic embedding system for light-economical pot seedling nursery machine显示文摘Most of the commercially-available pot seedling nursery machines are incompatible with soft-pot-trays and are labor-intensive and low in productivity.A soft-pot-tray automatic embedding system was developed in this study to achieve automatic embedding of the soft pot tray into the hard tray following sowing and covering with soil.A control system was constructed using the Arduino program development environment.An embedded-hard-tray automatic lowering mechanism and conveyor-belt-based pot-tray embedding system were designed.Dynamics analysis was conducted to derive an equation to describe the embedding process of the soft pot tray into the embedded hard tray.A prototype of the soft-pot-tray automatic embedding system was manufactured and tested.The analytical equation suggested that a minimum linear velocity of 0.86 m/s was required for a complete embedding process.The experimental results showed that the embedded-hard-tray automatic lowering mechanism was reliable and stable as the tray placement success rate was greater than 99%.The successful tray embedding rate was 100%and the seed exposure rate was less than 1%with a linear velocity of the conveyor belt of 0.92 m/s.The experiment findings agreed well with the analytical results.The proposed soft-pot-tray automatic embedding system satisfied the technical specifications for a light-economical pot seedling nursery machine. | Lintao Chen Xu Ma Cong Wang Hongwei Li Zehua Li Xueshen Chen Tao Chen | 2020 | International Journal of Agricultural and Biological Engineering2020,13,1: | 4 |

| 11 | Performance calculation and improved model research of direct-drive permanent magnet generator based on FEM显示文摘In some control strategies of the direct-rive permanent magnet generator(DDPMG),the mathematics model is excessively simplified and some complex nonlinear characteristics,such as core saturation and cross-saturation,are generally neglected.To solve this problem,this paper utilizes the frozen element permeability method to compute the armature self-and mutual-inductance,permanent magnet d-and q-axis flux varying with d-axis and q-axis current,then an improved model is presented in which the core saturation and cross-saturation between d-axis and q-axis are considered effectively.Based on this model,the method for computing the performance of the generators is also proposed.Taking a 1.5-MW DDPMG as an example,the time-stepping finite element method(T-S FEM) is adopted to analyze the performance with no-load and loaded conditions,the results show a good agreement with the ones obtained by the improved model.Compared with the simplified model,it is demonstrated that the presented model has the high efficiency and reliability and can provide a good reference for optimization design of DDPMG and other PM motors. | ZHANG Jian LI HeMing LUO YingLi DOU Na CUI XueShen | 2012 | Science China(Technological Sciences)2012,55,8: | 1 |

| 13 | Active coherent control of nanoscale light confinement:Modulation of plasmonic modes and position of hotspots for surface-enhanced Raman scattering detection显示文摘Multistep plasmonic nanostructures can induce the deep modulation ofelectromagnetic-field interactions on the nanoscale for positioning hotspots,and this generation of enhanced fields is important in many optical applications.In this article, a new strategy is proposed for fabricating a plasmonic double-stacked nanocone (DSC) nanostructure. In the DSC structure, a tunable plasmonichybrid mode proceeds from the strong coupling of the plasmonic resonance ofa fundamental cavity mode with a localized surface plasmon gap mode. In thenanostructure, the far-field response is deeply modulated and the hottest spotscan be effectively positioned on the top surface of the DSC nanostructure. Acontrollable and cost-effective mask-reconfiguration technique for manufacturingthe multiscale nanostructure is developed, which guarantees the generation ofthe introduced crucial stage on the DSC nanostructure. To evaluate the features ofthe plasmonic resonance, the DSC nanostructure is used as a surface-enhancedRaman scattering (SERS) substrate for detecting 4-mercaptopyridine moleculesunder specific excitation conditions. Its good performance, with an averagemeasured SERS enhancement factor as high as 108, | Zhendong Zhu Qixia Wang Fa Zeng Oubo You Sitian Gao Benfeng Bai Qiaofeng Tan Guofan Jin Qunqing Li Shoushan Fan Wei Li Yushu Shi Xueshen Wang | 2017 | Nano Research2017,10,9: | 0 |
| 14 | Application of the Stress Evolutionary Model in Hebei Province,North China显示文摘Coulomb stress changes associated with strong earthquakes occurring since 1484 in Hebei Province,China are investigated. The North China block has had many large historical earthquakes and some damaging earthquakes in the past century,including the 1976 Tangshan earthquake (M =7.8) . The study area and the adjacent areas of the province comprise the most active seismic fault zones and suffer from both strong and frequent events. The North China Block,which includes the Ordos plateau and the North China plain,is part of the Archean Sino-Lorean craton and one of the most active seismic regions in the world. Its movement is accommodated on major strike-slip intraplate fault zones that strike in the E-W direction. The faults in the study area contribute to the complexity of the stress field. Seismic hazard assessment in this region is attempted by calculating the change of the Coulomb failure function ( ΔCFF) arising from both the coseismic slip of strong events (MS≥6.5) and the stress built up by continuous tectonic loading on major regional faults. At every step of the stress evolutionary model an examination of possible triggering of each next strong event is made and the model finally puts in evidence that the fault segments that are apt to fail in an impending strong event,thus providing future seismic hazard evaluation. In this paper,the results of ΔCFF for Zhangjiakou fault, Xiadian fault and Langfang fault have been shown as examples to express the possiblity of generating future seismic hazard. | Zhang He Karakostas V.

| 18 | Synthetic Model for Prediction Seismic Risk in About 10 Years显示文摘In this paper, the relation that strong earthquakes and seismo-geological conditions bear with precursory phenomena has been analyzed. The information content concerning the long-term (i.e., a decade) seismic risk that various precursors can provide has been estimated by using the quantitative judgment method. On such a basis, a synthetic probability model for predicting the strong earthquake risk in about 10 years has been suggested. With the northern part of North China used as the test region, the feasibility of the model which is used for medium-term to long-term prediction has been proved. | Jin Xueshen, Dai Yinghua, and Liu Yunqing Seismologicai Bureau of Hebei Province, Shijiazhuang 050021, China | 1996 | Earthquake Research in China1996,10,2: | 0 |
| 19 | Analysis of the b-value and Seismic Deformation in the North of China显示文摘The accuracy of b-value is limited by the uncertainty of the magnitude.In order to improvethe accuracy of the b-value,a statistic methodology was used to estimate the number of eventsbased on that there are several magnitude values for one historical event by several methods toestimate the magnitude.The b-value and seismic strain rates were calculated for the threeregions in the North of China.The method proved to be valid for all the regions,especiallyfor the data with large fluctuation.In order to study the stress state,the strain rate tensorand the principal axes of tension and compression were calculated for each of three regions bythe data of the focal mechanism,finally the stress state in each region was discussed. | Qin Changyuan Jin Xueshen Shao Huicheng | 2000 | Earthquake Research in China2000,14,3: | 0 |
