Amur tigers had a copulatory pattem with no lock,thrusting, multiple intromission,and single ejaculation,which belonged to copulatory pattern No.11 in Dewsbury\'s copulatory-patterned system.5 The behaviors that accounted for most of the total time budget during the parturition period were grooming,lying and licking kittens,26.90%,26.23%and 23.83%,respectively.

东北虎的交配模式属于Dewsbury分类系统中的第11种，即无锁结、有抽动、单次插入、多次射精。5在分娩过程中，雌虎的梳理、卧息和舔仔行为时间最长，分别为26.90%、26.23%和23.83%；梳理、努责和舔仔行为发生频率较高，分别是37.95%、18.75%和12.50%。6在育幼过程中，雌虎室外期与室内期哺乳和亲仔行为的时间差异极显著(P＜0.01)，离开行为的时间差异显著(P＜0.05)。

Reference between CST and CSGC is a little difficult, but it is possible only the characteristic be hold, data possessed, representative be had in mind, and queried inturn.

发生分类和系统分类之间的参比有一定的困难，但只要把握特点、占有资料、着眼典型、依次检索还是可行的。

Then the reconstructed data are analyzed by multiple statistical indexes such as T2 or SPE to determine if the supervised process exceeds the normal control limits. If fault occurs, then the supervising program will alarm to prompt that the process has abnormal states. Because it is hard to get the inverse mapping from the kernel space to the original space after the original data are nonlinear mapped by the KPCA method, hence it is difficult to diagnose how the fault happened.

该方法首先构造系统正常时的核主元模型，然后将新的数据映射到该核主元模型，对数据进行重构，重构的数据用多元统计指标T2或SPE判断监测过程是否超出了正常的控制限，若有故障发生，则监测程序将给于警告，提示过程出现了异常操作状况。

This ionizer could either be used independently or act as a function module controlled by the master controller in professional air purifiers.

本机既可独立使用，也可作为专业空气净化系统中受上位处理器控制的负离子发生模块。

In the past century, people have devoted themselves to the worldwide problem——cancer, which does harm to people's health. Of late years, much research has been found that spindle checkpoint, which is a highly conservative mitotic watch system in the kinetochore of chromosome, has close correlations with chromosome instability and tumorigenesis.

近一个多世纪，人们一直在致力于攻克癌症这个危害全球健康的难题，近年来，大量的研究结果表明位于染色体动点上的一个高度保守的有丝分裂监督系统——纺锤体检验点，与染色体不稳定性及肿瘤的发生密切相关。

With the establishment and development of a socialist market economy system building enterprise production patterns, labor system has undergone great changes, triggered by conflicts in labor relations labour dispute cases and mass incidents have noticeably increased.

Even when the distance between the welding torch muzzle and the surface of the work piece changes, this control system will keep the stability of arc length, so as to achieve a stable welding process.

该系统能够在焊枪喷嘴和工件表面的距离发生变化时，保持电弧弧长一定，从而保证焊接过程的稳定。

The results showed that there were two kinds of grains in the cells,one was large and had low electron density,Gl for short,while the other was small and had high electron density,Gh for short.The latter ones had a circle around it which can be seen through the microscope.During the aroma releasing period,the shape of the two grains changed distinctly,which led to the inference that Gl was the leucoplast,the store-room of aroma precursors or energe substances,and that the Gh was probably the lysosome which is related to the enzyme system?s aroma producing.The circle around Gh is the formed fragrant constituents and the aroma forming is the result of the interaction of Gh and Gl .

结果发现，茉莉花瓣细胞中存在电子密度较低、体积较大的颗粒和电子密度较高、体积较小的颗粒（分别简称为Gl和Gh颗粒），并在Gh颗粒周围存在清晰的晕圈；在茉莉花释香过程中，两种颗粒在形态上均发生明显的变化，推测Gl颗粒可能是白色体，是茉莉花香气前体物或能量物质的贮存器，Gh颗粒可能为溶酶体，与香气形成的酶系统有关，Gh颗粒周围存在的晕圈可能是香气物质，香气物质的形成是Gl和Gh颗粒相互作用的结果。
