Dear All,

The following is the comments from Taiga of Shennan Circuits. Due to his mail sent to TGAsia was messed, so I resend his comments to you.

Hi Taiga, 

Thank you so much. We look forward to get your great help.

表示发生第I类错误（基本假设为真而被拒绝）的概率之大小。 

与之对应的概念是β误差，表示发生第II类错误（基本假设为假而被接受）的概率之大小。

在已知风险水平（指α误差/β误差)内，对基本假设是否可接受进行定量评定的方法。 

与 基本假设 相对应的概念是 对立假设 ，比如： 

基本假设 ：萨达姆无罪 

对立假设 ：萨达姆有罪 

 α误差 ： 萨达姆无罪却被判有罪的概率之大小（又叫厂家风险，表示合格产品被拒收的风险大小， 1－α表示系统将好的放行的能力） 

 β误差 ： 萨达姆有罪却被判无罪的概率之大小（又叫消费者风险，表示不合格产品被接受的风险大小，1－β表示系统将坏的检出的能力）
