Evolutionally, the amount of Dicer in organism decreases, but its functions become multiple and ex-tremely important.

不同生物体具有不同数量的Dicer，各Dicer既有功能上各自独立的特点，同时又有功能的冗余和交叉，而在进化过程中， Dicer的数量逐渐减少，功能却逐步整合从而表现出多功能的特点。

With this approach, a mathematical model of ASVG is developed. The method is simple and can be used to analyze the detailed internal properties of an ASVG. It overcomes the disadvantages of the two methods generally used, one is a method for modeling an ASVG by getting differential equations according to the topology of the ASVG circuit, which is very complicated and it is difficult to get a unified model expression of an ASVG; the other is a method for modeling an ASVG by considering the whole ASVG as a voltage source, which is too simple to analyze the detailed internal properties of ASVG.

该方法既克服了根据ASVG装置拓扑结构列写微分方程组的建模方法过于复杂且不易获得统一模型表达式的缺点，同时又克服了将ASVG装置等效为电压源的建模方法太简单而无法用于分析ASVG装置内部性质的缺点，具有建模简单又能分析ASVG装置的内部性质的优点。

Thus on the basis of MLFM Chinese-English codeswitching can be grouped as three types of inter-sentential codeswitching, intra-sentential codeswitching and diglossia codeswitching with sub-branches under each of them.This study also indicates that Chinese-English codeswitching in ads of Chinas mass media on the one hand shares some of its common motivations as in conversational analysis, and on the other hand as an advertising strategy it also shows the features of advertisement stylistics.

研究表明，中国媒体广告中出现的中―英语码转换的功能与作用既兼有语码转换的一般性特点，同时又因为广告文体的特殊性而具有广告语言的独特性。

Some physicochemical therapy as well as nake hepatocytes transplantation can't correct metabolic disarrangement because of severe hepatic diseases, ALF is characteristic of more complications and easily resulting in multiple organs dysfunction , and even multiple organs failure as well as higher mortality. transplant technique of encapsulated hepatocytes can inhibit immune rejection, and quarantee hepatocytes survival, the technique provides a new therapeutic method for ALF.

由于肝脏功能较复杂，一些利用物理、化学方法及裸肝细胞移植来代替肝脏解毒功能，但不足以纠正严重的肝病所致的代谢紊乱，易致多脏器功能障碍甚至衰竭，并发症多，死亡率高；而微囊化肝细胞移植技术，既可阻断受体的免疫排斥反应，又保证移植的肝细胞在体内长期存活，为急性肝衰治疗提供新的治疗方法。

In this study, we find that there are two problems when applying the techniques of discretization to obtain an approximated probability density function of the project completion time in stochastic activity networks. Namely, first, there exists neither exact data structure nor systematic scheme for the computer programming when applying the techniques of discretization; and second, error may arise from assuming independency between sub-paths in the activity network.

本研究发现在运用文献中的散式计算技术，求算随机性专案完成时间的机分配函时，存在个问题：第一，文献中既未提供明确的资结构也没有系统化的架构，足以将其转为计算机程式；第二，因为文献中的散式计算技术，皆假设随机性专案网中的各条子径彼此独，而造成明显的误差。

They neither ask questions nor answer them, opening their mouth only to disgorge lessons memorized by rote. Like Confucian scholars who lived only for passing the civil service exam, modern Chinese youth live with only one aim in life-- college.

他们既不提问题也不回答问题，只是为了背诵熟记的课文才开口，就像单单为了通过科举而生活的儒生那样，现代中国青年活着只有—个人生目的——进大学。

The author claimed that one of the norms of science, disinterestedness, is not to be equal with altruism, nor with that scientists should not be in pursuit of the material gain. Moreover it does not mean,"Scientific knowledge is actually interest-free".

本文认为作为科学家的行为规范"祛利性"既不是指科学家只应"为科学而科学，不追求科学的功利价值"，也不是指科学家只能"利他"、不应"利己"，甚至不是指"科学知识实际上与利益无涉"。

A disk controller,on the other hand,sends and receives data and sends status information.

而磁盘控制器既要发送和接收数据，又要发送状态信息。

This is the only way to dispel existing distrust and misconception and to build trust and confidence.

这是消除既存的误解与相互不信任而建立信任与信心的唯一途径。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.
