我们用一块负透镜，它将使光线发散一些。 - We analyze the positive and negative lens effect caused by the hole theoretically and give the expression of normalized transmittance in this condition
本文从理论上分析了因孔洞而产生的正透镜或负透镜效应并给出了归一化透过率的表达式。 - In the retrofocus project , a retrofocus structure with two elements is used in the object lens to enlarge fov and back working distance , in the head of which the negative meniscus have the effect of balancing aberration and deviating rays like a prism . and a standard hyperhemisphere immersion lens with high refractive index is put behind the object lens to satisfy the receiving of a detector with smaller photosensitive
反远距设计方案中物镜采用二片式反远距结构,增大了视场和后工作距离,弯月型负透镜在前,具有平衡像差和棱镜的偏向作用;物镜后放置高折射率标准超半球型浸没透镜,满足小光敏面探测器接收。 - When the laser beam interacts with the plasma , the effect of plasma on laser beam welding is mainly embodied , for example : the reflection , the scatter , the absorption , and the heat lens effect of the plasma acting on the laser beam and so on
等离子体对激光焊接物理过程及其质量的影响主要体现在等离子体与激光束之间的一系列相互作用上，如：等离子体对入射激光的反射、散射，等离子体对入射激光的负透镜效应，等离子体对激光能量的吸收，等离子体的反冲力效应，等离子体热源效应等。
