当添加晶须与裂纹面法向形成角度θ时，随角度θ的增加，裂纹尖端拉应力增加。当添加角度较大时，晶须根部基体承受了较大的应力，易遭到破坏性崩裂。同时，晶须内部主应力与晶须轴向之间的角度也随角度θ的增加而增加，造成晶须折断，致使造成晶须拨出的体积分数φap减小，降低了增韧效果。

E. , the formative process and final goal of MD from the angle of formative analysis, and a series of conclusions have been drawn as follows: The cross-the-border of governmental intervention and the shrivelling of market consist of the logical and historical prerequisites of MD. MD is proved to be able to promote economic efficiency and therefore boost economic development. According to theoretic analysis the final goal of MD is to reach the reasonable function border between government and market. As to the MD of RTE, its objective-orienting can be divided into three both independent and joint processes, and they are shrinking governmental intervention, expanding market function, and turning RTE into principal part of market.

文章第一部分从规范分析的角度论述了市场深化的目标取向，即市场深化的规范过程和终极目标，我们认为，政府越界和市场萎缩构成了市场深化的逻辑和历史前提，市场深化被证明可以带来资源配置效率的增长和促进经济的发展，而市场深化的限度就是政府和市场之间的合理的功能边界；乡镇企业市场深化的目标取向可分解为三个既彼此独立、又相互联动的子过程，即政府归位、市场扩张和企业的市场主体地位的确定。
