In chapter 5,we persue the ctiticality and complexity of thecritical sets.We describe carefully the Whitney's example in 1935.Meantime,we introduce some rsults about the critical sets and thecritical value sets,in particular,on W-sets and C-sets.And usingthe Lebesgue density theorem and the Vitali covering lemma weprove a rank zero theorem with Hausdorff measures.Finally wegive some examples to prove our results are sharp in the sense thatthe numbers k,m,n,s,〓,etc.,in the hypothesescan not be improved.

第五章研究临界点集的临界性和复杂性，并详细地描绘了Whit-ney在1935年的例子，同时也介绍了关于临界点集和临界值集的一些结果，尤其是W-集和C-集的一些结果，并利用Lebesgue密度定理和Vitali覆盖引理证明了一个与Hausdorff测度相关的秩零定理，最后举例证明我们的结果在定理的假设中的那些数字如k，m，n，s，a，r+/等不能被改进的情况下是最佳的。

In this paper, we mainly disscuss derivable mappings at zero point, Jordan derivations and 2-local derivations on some operator algebras. The details as following:In chapter 1, some notations, definitions are introduced and some theorems are given.

本文主要对几类算子代数上的在零点可导映射和Jordan导子以及2-局部导子进行了研究，具体内容如下：第一章主要介绍了本文中要用到的一些符号，定义以及本文要用到的一些已知结论和定理。

Current, in a few Party members, it is especially in cadre of leader of a few Party members, the good convention of criticism and self-criticism more and more by desalt.

当前，在一些党员中，特别是在一些党员领导干部中，批评与自我批评的优良传统越来越被淡化了。

In fact, it is almost inexplicable, but at a certain moment an emotion falls upon an artist and for some artists this feeling arrives in a descriptive form, while for others in a world of color.

事实上，这几乎令人费解，但在某一时刻，某一种特殊的情感降落再一个艺术家，对于一些艺术家这种感觉，以描述的形式到达，而其他一些是在色彩方面的。

Some of it deserved, but some of it not so deserved.

这会吸引一些人，也会受到一些人的不满。

However, some broods possess a few snails of the opposing hand, and in predominantly sinistral broods, the incidence of dextrality is surprisingly high.

一些窝中会有一些相反旋向的蜗牛，而780。且在主要是左旋的窝种，781。出现右旋的几率是令人惊奇的高。

However, some broods possess a few snails of the opposing hand, and in predominantly sinistral broods, the incidence of dextrality is surpri singly high.

可是，一些窝中会有一些相反旋向的蜗牛，而且在主要是左旋的窝种，出现右旋的几率是令人惊奇的高。

However, some broods possess a few snails of the opposing hand, and inpredominantly sinistral broods, the incidence of dextrality is surprisingly

可是，一些窝中会有一些相反旋向的蜗牛，而且在主要是左旋的窝种，出现右旋的几率是令人惊奇的高。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
