平面位移 meaning in English
horizontal displacement
Examples
- The surface deformation monitoring of the side - wall by combination of the forward intersection method with the analytical trigonometric elevation measurement demonstrates that the plane deformation and vertical deformation of the side - wall are small , and the quality of dam filling and side - wall construction is satisfactory
用能够满足精度要求的前方交会法与解析三角高程测量法结合的方法对边墙表面变形进行监测，结果表明，边墙平面位移和垂直位移均较小，大坝填筑和边墙施工质量可靠。 - In order to study the thermal performance and residual stress of microelectronic subassembly , in this paper , a newly optical interferometry method for 3 - d displacement measurement is developed based on wavefront interference theory . in which the moire interferometry provide the in - plane displacement , but the system is different from the conventional interferometry , the system applies the double diffraction of the specimen grating , the in - plane displacement sensitivity is a factor of 2 higher than that of the conventional moire interferometer . twyman / green interferometry method for out - of - plane displacement measurement is adapted , the advantages of the optical set - up are structure novelty , and the fringe patterns of the displacement fields shown high contrast and spatial resolution
为了详细研究试件的热变形特征以及残余应力的影响作用，本文在波前干涉理论的基础上，设计了一新型三维光学测试系统，该系统的平面位移测试基于云纹干涉方法，但采用与普通云纹干涉不同的光路系统，利用试件光栅和平面反射镜组形成的两次衍射，使平面位移干涉条纹倍增，测量灵敏度是普通云纹干涉的2倍，系统的离面位移场测试采用泰曼格林干涉光路。
