DSR应力仪原理是测定因应力引起的玻璃折射率的变化。当一定入射角的光到达玻璃表面时，由于应力双折射的作用，光束会分成两股以不同的临界角反射，借助测微目镜测出二光束之间的距离，即可计算出应力值。G：SP应力仪将激光束导入玻璃表面，在表面附近的薄层中以平行玻璃表面的方向运行一小段距离，应力双折射导致激光束发生干涉，测定干涉条纹的倾角就可计算出应力值。两种方法各有优缺点。DSR应力仪售价较低、可测定化学钢化玻璃，但操作要求较高、不易掌握、测量精度相对较低。衢州变量泵供应A10VSO71DFR1/31-P

一些小型石英石厂家还处于山寨模仿，占领市场，搅乱了石英石市场的原有次序。导致目前石英石销售市场质量良莠不齐，有些不良商家为利益化，在客户购买后进行掉包（使用位相似板材顶替）。对于石英石陌生的客户来说相似度达到7%的板材是很难分辨出来的，更何况在选购中并不可能完全记住板材的花色。
