The Stabilization Analysis of Automatically Adjustable Optical intensity System Using Iris Diaphragm;
采用可变光阑的自动调光系统的稳定性分析
In this method,light was adjusted by combining external trigger electronic shutter mainly and iris diaphragm assistantly.
该方法采用外触发电子快门和可变光阑相组合的方式进行调光,外触发电子快门调光为主,可变光阑调光为辅。
A Voronoi diagram accompanied with field nodes is produced, and a discrete model of a global stiff matrix is presented by means of stabilized smoothing nodal integration based on strain smoothing stabilization, and the displacement boundary conditions are enforced by a direct method.
生成了伴随于域节点的Voronoi图,利用基于应变光滑稳定方案的稳定相容节点积分得到了改进后的总体刚度矩阵离散化形式,并利用直接法施加位移边界条件。
