中文摘要：无损检测方法很多,本文讨论的是其中的超声法,分析了超声波的基本特性、传播特点、检测中引起的误差及补偿,以及由此提高这一无损检测技术的准确度等。

外文摘要：As a usual method of testing concrete ,it may test and destruct a prototype only once, which can not define the position, scope of drawbacks of concrete, and can not demonstrate the extent of structure damaged by the method . nondestructive testing con abandon these shortcomings, so is valued and applied in the engineering practice. This article analyzes the ultrasonic-method, one of nondestructive testing methods. It illustrates the basic natures, spreading characters of ultrasonic wave, viewing errors by this method and remedies. Finally, it stresses the importance and measure of improving the technique.
