In this paper, tolerance analysis mainly relates to three methods, viz."Extremum Method","Statistics Method" and "method of Monte Carlo". The character of the "Extremum Method" is to calculate the limit dimension of the close loop according to every limit dimension of the composing loop in order to ensure an entire frogging character, and get the tolerance of close loop.

极值法"的特点从保证完全互换着眼，由各组成环的极限值计算出封闭环的极限尺寸，从而求得封闭环公差；"统计法的特点是从保证大数互换着眼，根据各组成环的实际尺寸在其公差带内的分布情况，按某一置信概率求得封闭环尺寸实际分布范围，由此决定封闭环公差。

From this point of view this article on the above analysis and the

由此本文对以上观点进行分析与阐述

Chen's portraits are accentuated factual and recording. They show his respective counterpart in clinical frontality and thereby recall over-dimensioned passport-photos.

他们对各自的绘画对象作出像医疗卡上的照片一样的描绘，由此或许也能让人想起是放大了的护照照片。

The results show that extract from fugu ovary has different effects on different linkage of the immunologic system.

由此推测该提取物对免疫系统的不同环节，作用不同。

In part one (chapter 2-3), two new methods and systems of optical parallel logic operation are studied. Triple-in Double-out shadow-casting logic operation system is proposed and realized for the first time. Based on this, optical full adder and 3-bit decoder array logic have been obtained. It is the first time to use coding pattern and different reading-writing model to realize BSO-PROM optical parallel logic operation where the time-order operation is avoided, so that the computing speed of optical parallel logic gate which uses this kind of spatial light modulator is increased, and it is successfully used in optical symbolic substitution .

在第一部分，对两种新的并行光学布尔逻辑运算方法及系统进行了研究：首次提出并实现了三输入、双输出铸影光学逻辑运算系统及其由此得到的光学全加器，并提出一种以此为基础的3-比特译码器阵列逻辑，首次利用图形编码和不同的读写模式实现了无时序操作的BSO-PROM光并行逻辑运算，大大提高了这种空间光调制器用作光并行逻辑门的运算速度，使之成功地用于光学符号代换之中。

Teacher-student relation focuses on functionality and ignored the existence of teachers and students,the relation become functional relationship.

师生关系注重功能性而疏忽了师生作为人的存在方面，师生关系由此体现为功能性关系。

Of socialist market economy build and perfect, diversification trend makes evolution of structure of our country working-class interior become different estate, cannot deny the advanced sex that decides the working class from this, chinese the working class is the fundamental strength that drives advanced productivity from beginning to end.

社会主义市场经济的建立和完善，多样化趋势促使我国工人阶级内部结构演化成不同的阶层，由此不能否定工人阶级的先进性，中国工人阶级始终是推动先进生产力的基本力量。

While there have been a number of promising developments, all such theories suffer from the problem that the fundamental physical constants are unconstrained.
