speckle n. 斑点;斑纹〔常用 p. p.〕。 vt. 1.加斑点。 2.玷污。 3.点缀。 a speckled group [lot] 驳杂的人群。 speckled trout 斑鲑,斑鳟〔指各种鲑鱼,鳟鱼,因地而异〕。 dark hair speckled with gray 斑白的头发。
When the speckle interferometry or the electronic speckle pattern interferometry ( espi ) is applied to measure the continuous movement or deformation of an object , a temporal speckle interference field will occur 散斑干涉或电子散斑干涉( espi )计量应用于连续运动或变形物体时,就会产生一个时变的散斑干涉场。
Laser speckle interferometry was used as the experimental method to test the coefficient of thermal expansion ( cte ) of the metal composite leads used in the packaging structures and the thermal deformations of the entire packaging structures due to the change of temperature from room - temperature to 150oc 通过实验和数值模拟的方法对其热变形和热应力进行了研究。采用激光散斑干涉法测量了从室温到150oc的封装用金属复合引线的热膨胀系数和整个封装结构的热变形。
