光学仪器

Densitometer: An optical instrument used to measure the intensity of transmitted or reflected light.

密度计：用来量度透射或反射光的强度的一种光学仪器。

The polarization light used to affect the accuracy of optical test instrument, optical sensor and the quality of optical communication system, the depolarizer can be used to decrease the affection. Different kinds of depolarizer have different applications, so we need select proper kind of depolarizer for special application.

偏振光会对光学仪器测量精度、光通信系统传输质量及传感器精度产生影响，通常可以采用退偏器来减小这种影响，但每种退偏器都有一定的应用范围，要根据不同的应用来设计选择相应的退偏器类型。

Bull; The solid angle under which the specimen is illuminated must be adjustable or more popularly expressed: it must be possible to vary the diffuseness of the illumination

为了获得最佳的成像效果，在设计光学仪器时就必须考虑在光路中加入一系列控制器件来实现对 illumination ray 和 image ray 的控制和处理。

The CLM approach provides an accurate, repeatable, objective, and fast method for IOL dioptric power measurement over the range from 0 D to greater than +-30 D under both dry and in-situ simulated conditions.

该方法为人工晶状体屈光度测量提供了一种精确、可重复、快速的客观途径，测量范围可达到0D到±30D，并且适用于干燥条件和模拟在体条件的测量。标签共焦显微医用光学仪器眼科人工晶状体单模光纤

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
