摘要在最近十年，伴随着表面贴装印刷电路板生产自动化程度的飞速发展，对其相应的质量缺陷检查也提出了更高的要求，从简单的摄像系统到复杂的" 3 - d " x光检测系统，自动光学检测系统大量被各生产厂家采用。 - In order to detect the bottom thickness , cavity , leak and deformation of steel meshes in secondary lining of concrete in tunnel construction , the authors evaluate the wave character and the detected result in the second lining of the tunnel using surveying radar technology and conclude the wave character in the tunnel lining which has mass defect and tested the accuracy and reliability of this technique
摘要为检明隧道混凝土二次衬砌中的底界厚度、空洞、漏水、钢筋网变形等质量问题，利用探地雷达技术，通过对检测方法及工程检测实验的研究，进行隧道二次衬砌中雷达波形特征参数及检测结果评价，总结了隧道衬砌质量问题的雷达波形特征，验证检测方法的精度和可靠性。 - Specifically , to a test particle , its mass defect is am = m _ ( 0 ) - m , where mo and m are the mass of the particle when it is in the infinity and in the grav - itational field , respectively . to a spherical shell ( or a solid sphere ) , its mass defect is am = m _ ( 0 ) - m , where mo is the total mass of the matter scattering in the infinity and m is the mass of the gravitational spherical shell ( or the gravitational sphere ) combined by the matter scattering in the infinity
具体来说，对于试验粒子，当它由无穷远处运动到引力场中某点时，其质量由m _ 0变为m ，发生的质量亏损为m = m _ 0 - m ；对于球壳或固体球，当组成球壳或固体球的这些物质分散在无穷远处时，总质量为m _ 0 ，当这些分散在无穷远处的物质结合成球壳或固体球时，其质量变为m ，发生的质量亏损为m = m _ 0 - m 。
