用超声波对测法对受糖心产精国品免费入口*完整版腐蚀的混凝土糖心产精国品免费入口*完整版进行了检测。结果表明，超声波在不同腐蚀程度的混凝土中的传播速度是不同的，传播速度与糖心产精国品免费入口*完整版的抗压糖心产精国品免费入口*完整版具有一定的回归关系。在分析实验数据的基础上，建立了超声声速与糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版之间的函数关系，为用超声波法检测糖心产精国品免费入口*完整版糖心产精国品免费入口*完整版提供了数学依据。

The strength of concrete attacked by sulfate was tested by ultrasonic technique. The test results show that ultrasonic velocity of the concrete varies in different deteriorated concrete in sulfate environment, and the velocity has a favorable regression relationship with the strength of attacked concrete. By recursively analyzing the test data, the functional equation between strength of attacked concrete and velocity of ultrasound was obtained, and the certain reference for testing the strength of attacked concrete by using ultrasonic test method is presented.
