Applying the De Caen"s inequality of sum of the squares of the degree and Cauchy"s inequality, we obtain a strict lower bound and a strict upper bound of the largest Laplace eigenvalues only in terms of vertex number of a unicycle graph. Applying the Laplace matrix theorem of trees, we obtain an upper bound of the second smallest Laplace eigenvalues of a unicycle. Extremal graph whose second smallest Laplace eigenvalues reach the obtained upper bound is determined. We also obtain an upper bound of the second largest Laplace eigenvalues in terms of vertex number of the largest connected branch of unicycle graph, and obtain a theoretical method to calculate the second largest Laplace eigenvalues of unicycle graph. We obtain an upper bound of any Laplace eigenvalues in terms of vertex number of a unicycle graph. We also obtain the distribution of Laplace eigenvalues in the inter [0,n] in terms of the matching number.

本文得到了以下几个方面的结果： 1、利用图度平方和的De Caen不等式和Cauchy不等式给出单圈图的最大Laplace特征值仅依赖于顶点数的严格的上下界；利用树的Laplace理论给出了单圈图次小Laplace特征值的一个上界，并刻画了达到该上界的极图；利用子图的连通分支的顶点个数给出了单圈图次大Laplace特征值的一个上界，并给出了单圈图次大Laplace特征值一个理论上的一个求法；利用单圈图的阶数给出了其一般Laplace特征值的一个上界；利用单圈图的匹配数给出其Laplace矩阵谱在区间[0，n]上的分布情况。

In order to improve the accuracy, an idea raised on the interview is how the monthly increasing numbers of the customer impact the traffic of incoming call to the center. Collecting the monthly data from the Ministry of Communication, data covering the period of May 2000 through December 2001. Originally constructed the forecasting model with transfer function, the cross correlation function technique is demonstrated to the customer-traffic relationship, with particular focus on the customer lag structure. The result shown that the numbers of the customer in the third month will significantly effect upon the present call volume .

为了增加预测的精确度，从访谈得一假设在过去1、2个月新成长的客户数将对当月的话务量变化造成影响，所以从交通部统计处搜集TCC客户成长月资料，资料区间从民国八十九年五月至九十年十二月，欲建立电信公司的用户数成长数与服务电话的话务量变化之转换函数模式，但是以交叉相关函数方法显示的结果却是未来三个月预期的客户成长数将会对当月份的话务量变化造成显著的影响，以此作为本研究的发现。
