挡光 meaning in Chinese
be in the light; get in the light
◇挡光板 light barrier
Examples
- The equipment of " double light harrier " was developed and applied to measure object ' s velocity , which improved the precision of measuring impacting velocity
作者提出并完成研制的“双挡光片法”测速装置，成功地解决了冲击速度的精确测定问题。 - After measured the laser energy distribution of kunming slr station , the parameters of this non - gassian and non - spherical symmetric laser beam were deduced according to correlation definition . applying its laws and deduced laser beam parameters , the change of laser beam dirvergence angle was studied in detail when adjusts transmission system focus . moreover , calculation based on these measured data indicates that the laser shaded by the second mirror of telescope is amazingly up to 39 . 8 % , an optical element was designed for the settlement and it worked satisfactorily when put it into practice
之后测量了云南天文台激光的横向能量分布，根据相关定义确定了这束非高斯非球面激光的参数，应用它的传输变换规律和测量参数研究了调焦中激光发散角的变化，并根据测量数据计算出激光发射时副镜挡光比例达到惊人的39 . 8 ，研制出光劈解决这一问题，取得了很好的效果。 - In general , the thesis covers the following aspects : first , in accordance with the property of variable tuning optical attenuator ( voa ) , which is analyzed and discovered through diffraction theory , selected block plate and made attenuator , and achieved satisfactory effect by experiment in light transportation circuit
针对可调型机械挡光衰减器的挡光特点，从衍射理论的角度分析和发现该器件的衰减特征，并根据该特征选择挡光片，制作了衰减器。在传输光路上试用，获得了较好的效果。
