单模的 meaning in Chinese

unimodal
unimodular

Abstract : a laser damage facilities , which has mm size spot and operates in tem00 mode ， were achieved . in order to know the reasons of laser damage , the laser energy density was controlled near the damage threshold of the oxide thin films . according to the examined near - threshold damage morphology , the damage mechanisms of the optical coatings can be divided into two types . one was caused by melting of the coating materials , another by exploding , induced with the inner stress of the film . the plasma generated was an important reason to expand the damage area
文摘:采用毫米量级大光斑的近单模的激光器，控制入射薄膜表面的激光能量，获得了几种常见单层膜和增透膜的损伤形貌，实验结果表明，薄膜的损伤可区分为熔化型和应力型两种，薄膜表面等离子体对损伤斑点的扩大有重要作用。
