Though the primary stimulator of 1H is not clear, it is related to physical, cell and body fluid IH is a chronic process involving multiple faction injury and blood flowing abnormal are revamped as the main reason, the proliferation level depend on the length and width of the injure of vessel large amount research illustrate injury cause many growth factor infolded in IH, for example: template derived growth factor, fibroblast growth factor, transmission growth factor , endothelin (ET-1) et al, some early responsive gene such as c-fos、c-jun c-myc also take part in SMC proliferation after vessel injury.

虽然IH的确切起始刺激因子并未阐明，但已知与物理、细胞和体液因子有关。IH是一个多因素参与的慢性过程，损伤和血液动力学异常一真被认为是IH的主要因素。内膜增殖的程度有赖于血管损伤的长度和深度。近年来大量的实验研究结果表明，损伤等刺激引起的众多的生长因子样物质在IH中起关键作用。如血小板源性生长因子、碱性纤维母细胞生长因子、转化生长因子β、内皮素-1（ET-1）等诸如C-fos、C-jun、C-myc等早期应答基因也参与了血管损伤后SMC的增殖。

In view of the short duration in the test of a fuze's self-destruction time,we discussed the possible factors such as fuze structure and processing quality,the angle of fire,weather and barrel conditions.Meanwhile,we used the method of variance analysis to process significance test for different barrel conditions on the malfunctioning of fuze self-destruction.After eliminating some other possibilities,we retrieved the fired shell which has abnormal band with fin,and finally found the real cause of the problem mentioned above.

由一带离心自毁机构引信自毁时间出现偏短的试验结果出发，从引信结构参数和加工质量、射角、气象条件、身管状态等方面入手，着重用方差分析法对身管状态进行显著性检验，探讨引起引信自毁时间异常的因素，在逐一排除了其他因素后，通过射击回收的方法发现弹带有异常飞边，找出了问题的原因。

Although the etiology and pathophysiology of LBP during pregnancy are poorly understood, one plausible hypothesis is that causes of LBP in pregnancy are multifactorial (i.e., biomechanical stress on ligaments and joints, muscle fatigue, and the effect of the hormone relaxin on joint laxity), with ≥1 factors dominating in an indiidual case.

尽管对孕期LBP的病因学及病理生理学了解甚少，有一个似乎可信的假说宣称：孕期LBP是多因素引起的（施加在韧带和关节的生物力学上的应力、肌肉疲劳及松弛肽的关节松弛作用），对单个对象来说，有不止一个因素交互作用。

Jewish Immigrant Problem was the result of the political,economic and historical development in the USSR; Soviet government's restrictive policies to Jewish immigration led to the emergence of a new,special political gr oup-the Refuseniks, which set the aim of their activities at emigrating abroad ; the emigrating will and the activities of the Refuseniks attracted the attention of the West,especially Americans,and became an important factor influencing the economic and trade relations between the USA ...

苏联犹太移民问题是苏联历史和政治、经济发展的产物。由于受多种因素的影响，苏联对犹太移民的意愿采取限制性的政策，由此产生了苏联政治生活中移民申请被拒绝者这一特殊的政治群体，他们以移居苏联国外为其主要的政治目标。苏联犹太人的移民意愿及移民申请被拒绝者的活动引起西方社会尤其是美国的关注，并在一段时期内成为影响美苏经济贸易关系的一项重要因素。戈尔巴乔夫实行的改革开放政策在一定程度上缓解了这一问题，此后苏联的解体使这一问题的性质和重要性均有所转变。

In this dissertation,three principal factors which are responsible for thedistortions of MnO6 octahedra were investigated,these factors are the Jahn-Tellereffects,the size mismatch between A-and B-site cations,and the vacancies on A-and/or B-site,respectively.

本论文就是考察引起MnO6八面体畸变的三大因素及其对性能的影响。这三大因素是：Jahn-Teller效应，A位和B位离子半径的不匹配，A位和B位空位。

The study examined the influences of imagery environmental factors such as lighting voltages in a flue-cured tobacco leaf image capture lamp box, digital camera brands, focusing distances and resolutions on the result of image recognition.

研究灯箱中采集烟叶图像时照明电压、不同品牌数码相机、聚焦距离及相机分辨率等成像环境因素对图像识别结果的影响，用相对颜色法对因成像环境因素影响而引起的烟叶图像颜色变异进行实时校正。
