By using the estimate for trigonometric sums and the esitimate for general Kloostermann sums, we study the asymptotic properties of N, and give a sharper asymptotic formula.

本文的主要目的是利用三角和估计及广义Kloostermann和估计研究了N的渐近性质，并得到一个较精确的渐近公式。

This paper introduced the odd sieve sequence, the methods of character, estimate and triangle sum are used to study the mean value of the divisor function. An asymptotic formula of the divisor function is gave in the odd sieve sequence set to through the analytical method.

引入了奇筛数序列，主要利用特征和估计及三角和方法，研究了除数函数的均值性质，并通过解析方法给出了除数函数在奇筛数序列集合中的一个的渐近公式。

The prospects of PSD′s application in optical trigonometry, automatic check and highprecision measurement are discussed.

最后对PSD在光学三角法测量、自动检测以及高精度测量中的应用作了进一步的讨论与展望。

In chapter three, we deal with the other equivalent propositions of the octahedral axiom and applications.

在第三章，我们讨论三角范畴定义中八面体公理的其它等价命题及应用。
