1. In this paper, strong Moire-fringe density and direction are studied in noisy phase maps using a preprocessing method of automatic Moire-fringe analysis. 本文采用一种自动条纹分析的预外理方法,对噪音相位图中的莫尔条纹密度和方向的估计进行了分析研究。
2. This paper describes the use of phase shifting for automatic analysis of fringe patterns resulted from photoelasticity, the fringe pattern and all of the points stress can be get automatically. 本文采用相移法研究了光弹性条纹的自动分析技术,可以自动采集光弹条纹图像并求得全场应力数据。
3. ignition started at the area around the fuel spray fringe, and then high temperature area always distributed at the fuel vapor fringe. 着火首先发生在油束外缘区域,并且随着燃烧进行,高温区一直出现在燃油蒸汽的外层。
4. Cut the fringe section asymmetrically. Using the free hand technique, make a transition from the left fringe contour to the right side (chin length). 使用自由的修剪手法,制造从右耳朵的上面顶端的到颈区的中心连接。那里是现在颈区的中心点。
5. A graphic method based on principle of superposition and self-equilibrium of residual stress is used for discriminating the thermal stress fringe quantitatively from the frozen stress fringe in PMMA. 本文基于叠加原理和残余应力的自平衡特性,建立了一种将有机玻璃热应力条纹与冻结应力条纹进行定量分离的图解法。
