isochromatics等差线
1.The multi image arithmetic module isused for separation of isocinics,multiplication of isochromatics and phase shift in photoelastic image processing.该模块在光弹性图像处理中可实现等倾线的分离、等差线的倍增及相移技术
2.With the aid of two coherent light sources, the fringe orders of isochromatics have been determined through comparing the fractional quantities of the corresponding fringe patterns.分别采用波长为630nm和532nm的激光作光源,根据在不同光场下获得的等差线条纹光强变化,可实现等差线条纹的自动定级。
3)equidifferent line等差线
1.The method employd the equidifferent line of the main and / or the bour sections could easy separate the normal stress for any complex shapes of construction.在此基础上得到了只使用主要横截面及其附近的等差线，并且不管试件形状如何，能容易地分离主应力的方法。
2.In photoelasticity experiment,it is usually difficult to measure the series of equidifferent line precisely due to various factors.在光弹性试验中，由于各种不利因素的影响，往往不能精确测得等差线级数。
