摘要
本文提出了改变目前超声回弹法测点采用的母体范围，采用X2-分布拟和检验法检验混凝土强度的母体分布，混凝土强度标准值按其概率分布的0．05分位数确定。
This paper defies the scope of populahon of current ultrasonic-rehaund methed's measare points and employs X2-goodness-of-fit test for distribuhon to define the distribuhon of concret strength.Characteristic value of concrete shength is deduced according to 95% probability of concrete strength.
