本文叙述了压缩机连杆轴承内的间隙大小对油膜厚度的影响之试验研究结果。活塞式压缩机的使用年限决定于机器内摩擦付的使用期限。保证滑动轴承寿命长的必要条件是:在轴颈与轴承瓦之间应有油膜存在。因为既定尺寸和既定工作规范下滑动轴承内的液体摩擦,只有在一定的摩擦面间间隙范围内才能存在,所以这个间隙范围的确定,使

Idiopath.c h.pereosinoph.lic syndrome (Ih.S) is a disorder ch.racterized by increased eosinoph.l count (eosinoph.lia) along with.organ dysfunction secondary to organ infiltration of eosinoph.ls and release of inflammatory markers [1-4], with.no obvious cause for eosinoph.lia. Th. onset of symptoms is insidious in most of th. cases and eosinoph.lia is detected incidentally. h.wever, in oth.rs, th. initial manifestations are severe and life-th.eatening due to th. rapid evolution of cardiac or neurologic complications [5]. Renal involvement is rarely reported [6] in Ih.S. h.rein we reported a case of Ih.S with.predominant renal involvement as neph.otic syndrome with.focal necrotizing IgA neph.opath..

研究步态分类的一种新方法

东北工学院学报 1993年第5期14卷 445-448页

作者：柳洪义闻邦椿 h.斯欧格东北大学斯图加特大学

提出一种研究步态分类的新方法——“事件矩阵法”。在给出事件矩阵和有关步态分类研究中的一些定义的基础上,应用事件矩阵对步态分类问题进行了讨论,表明“事件矩阵法”比采用步态矩阵研究步态分类问题更简单、更有效。

Kernel-driven model was ch.sen to calculate global albedo in th. project of multiangular remote sensor MODIS. Th. best kernels were selected by th. venerable 'least square' meth.d. Th. result of th.s meth.d was very unstable wh.n only a small amount of angular observations is available. A new criterion h.s been estalish.d, called 'least variance' for th. kernel’s selection. It takes into consideration th. effects of model and measurement based on th. information inverse th.ory. Several tests sh.wed th.t 'least variance' h.s many advantages. First, it is less sensitive to noises. Second, it operates well in small sample size. Th.rd, it depends less on th. sampling position.

Th. effect of grain size(in th. range from 4 μm to 12 μm) on th. h.drogen embrittlement(h.) of 304 austenitic stainless steel(ASS) was studied. h. susceptibility result sh.ws th.t h. resistance increases with.grain refinement. Electron backscattered diffraction kernel average misorientation(EBSD-KAM)mapping sh.ws th.t th. strain localization can be mitigated by grain refinement. h.nce, strain localization sites wh.ch.act as h.gh.ays for h.drogen diffusion and preferred crack initiation sites can be reduced along with.grain refinement, leading to a h.gh.h. resistance. Meanwh.le, grain size sh.ws no influence on th. strain induced martensite(SIM) transformation during th. h.drogen ch.rging slow strain tensile test(SSRT). h.nce, th. SIM formed during h.drogen ch.rging SSRT is not responsible for th. different h. resistance of 304 ASSs with.various grain sizes. h.drogen diffusion is supposed to be controlled by a competition between sh.rt-circuit diffusion along random grain boundary(RGB) and h.drogen trapping at dislocations, leading to a maximum h.drogen diffusion coefficient in th. 304 ASS with.an average grain size of 8 μm.

Neural Regeneration Research 2015年第1期10卷 22-24页

作者： Th.mas h.Tung Center for Nerve Injury and Paralysis Microsurgical ReconstructionDivision of Plastic and Reconstructive SurgeryWashington University School of Medicine

Th. slow rate of nerve regeneration after injury or recon- struction remains a clinical problem because it proh.bits th. timely reinnervation of distant target muscles be- fore th. irreversible degeneration of th. neuromuscular junction and breakdown of muscle tissue. As such. h.gh.（proximal） nerve injuries result in th. incomplete recovery of motor function and poor functional outcomes despite current and timely surgical management. Experimentally, several strategies h.ve been sh.wn to enh.nce nerve regen- eration and improve functional recovery in animal models but translation to clinical practice h.s not been realized. Two potential treatments, tacrolimus （immunosuppres- sant） and electrical stimulation are commonly used for oth.r reconstructive indications and as such. are both.read- ily available clinically. Th.re is some evidence, wh.ch.will be reviewed in subsequent sections, th.t th.se approach.s may also be useful in enh.ncing neuronal regeneration.
