Modeling of laser adjustment for large diameter tubes using robotic kinematic theories

引用

Advances in Manufacturing 2018年第4期6卷 401-408页

作者： pin Li Jun-Tong xi School of Mechanical Engineering Shanghai Jiao Tong University Shanghai 200240 People's Republic of China School of Mechanical Engineering Jiangsu University Zhenjiang 212013 Jiangsu Province People's Republic of China

Laser adjustment is a new technique that employs laser forming processes to align components along specific directions. To develop a laser adjustment solution with a minimal number of bends, herein, a new modeling and calculation method that uses robotic kinematic theories is introduced. A numerical example and the corresponding laser adjustment solution are presented. The simulation results suggest that a straight tube with a flange connector can be adjusted to match the corresponding connector with three bends. Finally, the simulation results were verified using experiments. The maximum deviation was approximately 0.4 mm and the deviation of the flange connector was smaller, showing that a good adjustment quality could be achieved using the specific adjustment solution.

Ginkgo leave, a naturally abundant resource, has been successfully employed as the raw material to prepare ni- trogen doped porous carbon （NDPC） materials. The preparation of the porous carbon does not involve assistance of any activation or template technique. The as-obtained NDPC shows favorable features for electrochemical energy storage, which can not only provide multiple sites for the storage and insertion of Li ions, but also facilitate rapid mass transport of electrons and Li ions. As a result, the NDPC when evaluated as an anode material for lithium ion batteries delivers high reversible capacity （505 mAh·g-1 at 0.1 C）, excellent rate capability （190 mAh·g-1 at 10 C）. These favorable properties suggest that the NDPC can be a promising anode material for lithium ion batteries （LIBs）.

Annealing Effects on Properties of Bi—Substituted Garnet Films with Perpendicular Anisotropy Prepared by a Sol—Gel Method

引用

Chinese Physics Letters 2003年第5期20卷 746-748页

作者： ZHANGYue-pin WANGxian-Ying RuanHao SHENDe-Fang GANFu-xi ShanghaiInstituteofOpticsandFineMechanics ChineseAcademyofSciencesShanghai201800

Bi-substituted garnet films with perpendicular anisotropy have been prepared by a sol-gel method. Annealing effects on magneto-optical properties and structures of the films are studied. The results indicate that the Kerr hysteresis loops of garnet films have good squareness at annealing temperatures above 650°C, the coercive force Hc of these films increases from 1070 to 1570 Oe with the increasing temperature from 650°C to 700°C. The Kerr rotation of the films was changed with the increasing annealing temperature, and there is a maximum value (0.82°) at 675°C. It was found that the structure of the films is a single phase of garnet without preferring orientation when the annealing temperature is about 650°C, but a new phase (Bi2Al4O9) can be formed when the annealing temperature reaches 675°C, another new phase (Bi2Fe4O9) appears when the annealing temperature is about 700°C.

To study the effect ofαphase morphology(equiaxedα(αE)/lamellarα(αL))on the in situ tensile behavior of TC21 alloy,the slip band,dislocation,crack initiation,and propagation were analyzed by scanning electron microscopy(SEM)with in situ tensile stage and transmission electron microscopy(TEM).The results show that the slip bands first concentrate in theαE phases and easily truncate at theα/βphase boundaries,whereas the slip bands move across theαlamellae in theαL *** are easily generated inαE orα/βphase boundaries with large plastic *** the quantity ofαL is more thanαE,the crack tip is more easily deflected atαphases orαclusters with different orientations,making the main crack propagation path more *** the volume fraction ratio ofαE toαL is~3:4,i.e.,the volume fraction ofαE is close to that ofαL,TC21 alloy exhibits better strength and slower crack propagation rate.

The equal-efficiency-proving of fluorescence quenching and enhancement equation

引用

Chinese Science Bulletin 2005年第22期50卷 2571-2574页

作者： YANG Manman xi xiaoli YANG pin College of Chemistry and Chemical Engineering Institute of Molecular Science Key Laboratory of Chemical Biology and Molecular Engineering of Ministry of Education Shanxi University Taiyuan 030006 China

Through the fluorescence and ultraviolet- visible spectrophotometry we have studied the action of ce- foperazone sodium and worfloxacin, two kinds of medicine with albumin, and examined the equal efficiency quality of fluorescence enhancement and fluorescence quenching equa- tion. The result shows the equal efficiency of calculating dis- sociation constant. In this article, we obtain the dissociation constants of the action of the two kinds of medicine with bo- vine serum albumin, energy- transfer efficiency, the distance of donor-acceptor and quenching constants. The above shows that the action is not caused by dynamic collision but by the binding of medicine and albumin. This article specially points out that the [Mt]/[Pt], which is the ratio of the maxi- mum mol concentration of the quenching agent (medicine) to fluorescent (albumin) mol concentration when the quenching ends, is very important because it is the maximum binding number of quenching agent molecule to a fluorescent mole- cule. There is no more quenching after adding more quench- ing agent beyond this quantity to fluorescent solution. This quantity is determined directly and strictly by experiment, so is also of important significance when discussing quenching efficiency and binding situation of donor-acceptor.

A new species of the genus Macrobiotus(Tardigrada:Macrobiotidae) from Southeastern China

引用

动物分类学报 2014年第2期39卷 224-228页

作者： pin Zhang xi-Zhai Sun College of Life Sciences Shaanxi Normal University Department of Life Sciences Heze University

A new species Macrobiotus wuyishanensis sp. nov. （Tardigrada： Macrobiotidae） is described from Mt. Wuyi, Southeastern China. It is most similar to Macrobiotus spectabilis Thulin, 1928, but differs by lacking fine punctuation on the distal half of the projections on the egg, a ring of polygons that circle the base of each projection, and punctation between the projections on the egg shell. It is also similar to M. grandis Richters, 1911, but differs by smaller body size, lacking polygons and punctations between the projections on egg shell.
