The structural function and its implement of TIDS System developed in the AutoCAD package are introduced in this paper. In this system, so long as a basic size and tolerance code are inputted by users at a time, the deviation can be searched and printed or dimensioned in the drawing directly. Thus, automation is completely realized to indicate tolerance in the CAD System.

本文介绍了作者在AutoCAD软件中开发的子系统TIDS的功能及其结构和功能实现等，该系统能根据用户一次输入的基本尺寸和公差带代号检索出极限偏差数值并作打印或自动标注，从而在CAD中完全实现了尺寸公差标注的自动化。

We find that the scattering process of the charge and lattice defect is different under different strengths of electric field and the interchain coupling interactions.(1) The results of the dynamics of oppositely charged polarons in polymer chains show that:①At a weak field (.1 mV/A), they finally scatter into an entity, which will be dissociated as a pair of neutral solitons after their first collision and separation.

1聚合物中极化子对的非弹性散射对电场强度的依赖关系表明：在弱场(小于0.1mV/A)时，电荷由于量子隧穿相互抵消，但不改变符号，极化子晶格碰撞后带着剩余的电荷返回，但是它们不能分得很远，在电场作用下，可进行第二次碰撞，结合成一个整体，然后又分成一对中性的孤子对。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
