为了适应学校的信息化建设，提高工作效率，减轻教务人员的工作压力，开发了这套证书统计分析系统。利用该系统可以轻松地统计和分析各种证书的获取情况。在实现各种功能时，为了提高自动化程度，需要大量使用拼接字符串。由于字符串的不可变性，造成了系统性能极其低下。本文以该系统为例，提出了一种可行的字符串拼接的优化技术，大大提高系统的性能。

In order to adapt to the information construction of the school, improve the work efficiency, reduce the pressure on academic staff, we developed this certificate statistical analyzing system. By using this system, we can easily access statistics and analysis of various certificates. In the realization of various functions, in order to improve the degree of automation, we have to use a lot of string concatenation. Because of the string’s no variability, it causes the system to funtion in very low efficiency. In this paper, by taking the system as an example, the author puts forward feasible optimization technique of string concatenation. It can greatly improve the performance of the system.
