For experimental setup to calibrate spectral radiance by applying a diffuse plane, the measured spectral radiance can be obtained through integral of spectral radiation flux entering the spectrometer.

在利用漫反射板标定光谱辐亮度的实验装置中，标准灯完全可以近似为点光源。通过对进入光谱仪的辐射通量的数值积分，可以对应求出仪器的实测光谱辐亮度的计算公式。

Complete Principle of Measurement , as the basic literature of large calendar mathematics series Chongzhenlishu, was the beginning of the Western trigonometry, spherical astronomy and measurement into China, involving area, volume measurement, flat triangle, spherical trigonometry and spherical astronomy's theory as well as measuring instruments'applying. Complete Principle of Measurement embodies Chongzhenlishu's axiomatic mathematics and astronomy and makes a contribution to the further spread of the Western learning.

《测量全义》作为编撰大型历算丛书《崇祯历书》的基础文献，是西方三角学、球面天文学及测量术系统传入我国之始，涉及面积、体积测量，平面三角、球面三角和球面天文学的基本理论以及测量仪器的制造和使用等，是《崇祯历书》中公理化数学和天文学体系的体现，为西学的进一步传播做出了贡献。

Using of a coaxal shutter system, the camera has a rather simple structure, lighter wieght and smaller dimension than other 35mm high speed cameras.

由于它采用了一种同轴快门系统，使摄影机的结构大为简化，整机的尺寸、重量以及价格也较同类型高速摄影机大大减小，主机重量小于8公斤，是同类仪器的1/5～1/10；售价只及同类产品的1/3～1/5，因此它是各靶场旧设备更新的一种理想的高速摄影机。

This rather unimportant variety of ineffectualist can be recognized immediately by a sort of fetishistic worship of research instruments. They are as fascinated by the gleam of metal as the lark is with its own reflection in a mirror.

没有效率的科学家中，有一小类就是所谓的崇拜研究仪器的狂人，他们对金属的闪烁非常着迷，就像是夜鹰对它在镜里的反影着迷一样。

The specimen horizontally into two of the instrument, sample between the edge of the circular underpan between the minimum distance of not less than 50-mm, measurement should be gently 2 ~ 3 mm/min will activities on blank sample in order to avoid any impact, and make sure the piece and thickness measurement plane parallel.

将试样水平地放入仪器的两个平面之间，试样的边缘与圆形底盘边缘之间的最小距离不小于50mm，测量时应轻轻地以2～3mm/min的速度将活动平面压在试样上，以避免产生任何冲击作用，并保证试片与厚度仪测量平面的平行。

Condition Based Maintenance is schemed according to the results of various instruments and visitatorial records of personnel, on the basis of the analysis of technicians and the current status of Transformer.

状态检修则是根据各种仪器的监测结果和运行人员的巡查记录，经过运行技术人员的分析，按照设备运行的实际情况，实事求是地策划设备的检修行为。
