作者编写了一个统计程序来获取指纹验证的统计结果，但发现所有验证结果均为零。经过排查，发现问题是由于保存指纹数据的数据库大小为零。更新数据库后，问题得到解决。

I wrote a statistic program to get the statistic result of verifing finger print. It had runned for about 44 hours. This morning I get the result. But I am so amazed at the statstic result that all verified result is zero.

I began to find out the reason. Afer testing, I am sure that the statistic program is correct, the root is the database to save all finger print data, its size if zero. I updated the database, run the little program again. The statstic result is right.

I have to make a statistic again!
