In photoelastic stress analysis, the accuracy of analysis can be improved by using fractional isochromatic fringes, so it is very important to study the approach for producing fractional fringes.

在光弹应力分析中，利用分数级条纹可以提高分析精度，于是，产生分数级条纹的方法研究就变得非常重要。

We use Finite Element Method to simulate the isoclinic and isochromatic patterns of photoelasic experiments and the fringes while the secondary principle stress varies along the path of light and the secondary principle direction fixed.

This moire effect is used in combination with photoelasticity to separate the principle stresses in the two-dimensional stress problem. The model was made by epoxy resin, its surface was covered with a printing film, which have 300 lines per inch.

以每时300道条纹的网格薄膜贴在环氧树脂模型上，采用光测法冻结技术把应力冻结下来，然后在偏振场中测取等差线，与标准网板重叠测取水平位移及垂直位移条纹图。

The additional optical path difference of Michelson interferometer without compensator is analyzed, and the equation of interference pattern is deduced.

通过分析缺失补偿板的迈克尔逊干涉仪中的附加光程差，推出干涉条纹满足的方程式，并用计算机模拟了动镜移动过程中变化的干涉条纹，与实验结果相一致。

The most common cause of moire is the interference between scanning lines and some other periodic structure such as a line pattern or dot pattern in the original scene, a mesh or dot pattern in the camera sensor, or the phosphor dots or other structure in a shadowmask picture tube.

引起莫尔条纹最常见因素是扫描线和某些其它周期性波纹之间的干扰，如原场景中的线或光点图形、摄象机传感器中的网纹或光点图形、遮蔽屏摄象管中的闪烁光点或其它波纹。

The new photoplasticity analysis theory was put forward by the research of the change from photoelasticity to photoplasticity.

在冻结应力的情况下，光塑性条纹与试件的应力成比例，是应力条纹。

M. The design of a time resolved flat-response x-ray imaging system has been accomplished, with the combination of Wolter x-ray microscope, x-ray streak camera, and a compound filter.

利用Wolter X光显微镜收光立体角大，而且在收光立体角截面上容易划分成不同区域的特点，用X条纹相机作为图象记录系统，完成了一套在0.1～1.5 keV能区对X光能量平响应的高时空分辨测量系统的设计。

In order to obtain the correct height reconstruction of a measured object through the traditional Fourier transform profilometry, the connecting-line between the exit pupil of the projecting lens and the entrance pupil of the imaging lens must be horizontal and set to parallel to the reference plane.

在拍摄过程中，采集完参考平面的光场后，只需要再采集一帧条纹图形，通过傅里叶变换、频谱滤波、逆傅里叶变换、相位展开等处理后就能得到物体的三维数据。采用传统的傅里叶变换轮廓术进行三维物体面型测量时，必需保证投影装置出射光瞳和成像装置入射光瞳的连线与参考面平行，并且它们的光轴应在同一平面上，才能得到较为准确的测量结果。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
