The main problem of existing static vulnerability detection methods based source code analysis is their high false positive and false negative rates.

现有的采用基于源代码分析的漏洞静态检测方法中存在的主要问题是误报率和漏报率较高。

Unfortunately, they also have a relatively high false positive rate -- enough that I need to manually examine some of the spam folders from time to time.

遗憾的是，这些过滤器的“误承认”的发生率比较高 — 以至于我不时地需要手工来检查垃圾邮件文件夹中的 某些邮件。
