The traditional method the confidenceinterval is not the shortest, so it is not the best one in this sence. Obtained the shortest confidenceinterval in theory.
用传统方法得到的两正态分布方差比的置信区间显然不是最短的，因而就此意义而言也不是最佳的。

The confidenceinterval of parameter of Gama distribution, obtained by using the traditional method, is obviously not the shortest. So it is not the best one in this sense.
