求翻译：此外，本文在参阅文献资料的基础上，对其期望方差、可加性、与指数分布之间的关系、渐进正态性等性质进行归纳总结，并给出较为合理的证明过程。是什么意思？

In addition, refer to the literature on the basis of the nature of the expected variance, the relationship between the additive, and exponential distribution, asymptotic normality and other summarized, and gives a more reasonable proof process.

In addition, this article on literature, on the basis of their expected variance, the exponential distribution, and the relationship between normal and incremental nature of such a summary, and to a more reasonable certification process.

In addition, this article in the reference literature material foundation, to its expectation nature and so on variance, additivity, with exponential distribution between relations, evolution normality carries on the induction to summarize, and gives the more reasonable proof process.

In addition, refer to documents on the basis of this article, its expected variance, additive, and the relationship between the exponential distribution, asymptotic normality of nature, such as sum, and gives more reasonable proof of the process.
