光源

FOG is one kind of laser gyroscopes. IT is based on the interferential theory of Sagnac. And its lamp-house is used with laser. A photic loop is made by fiber. There are clockwise and withershins sheaveses of lights transfer in the circle. With the turn of the circle ,the two lights introduce phasic difference ,so the angle velocity is measured.

Largely because of advances such as the development of new sources of x ray illumination.

这很大程度是因为例如X射线在新光源上的发展的结果。

The rules of photo bioactivities are: Without illumination, the tested xanthene derivatives showed almost the same level of inherent toxicity to the same organism, which showed the inherent toxicity of xanthene derivatives were primarily dependent on the structure of parent molecule. Upon illumination, the photosensitizers showed obvious phototoxicity to all organisms. The xanthene derivatives showed stronger phototoxicity to Gram-positive bacteria. With the increasing number of halogen substituents, the singlet oxygen yields increased and the phototoxic activity increased too.

呫吨类化合物的生物活性的变化规律为：未经光照的条件下，呫吨类化合物的对同种待测微生物的固有生物活性基本相同，说明固有毒性可能主要决定于化合物分子的母核结构，其卤素取代基团对其影响较小；经实验光源照射下，所测MLC值明显低于未经光照条件下的值，表明呫吨类化合物对三种微生物的光敏活性明显强于对其相应的固有活性；呫吨类化合物对革兰氏阳性菌能发挥较大的光敏活性。

Based on the extended Huygens-Fresnel principle and the quadratic approximation of phase structure function, we have derived the analyticl expression of the spatial degree of coherence for partially coherent flattened beams propagating through the slant turbulent atmosphere with the help of tensor integral, then analyzed the effects of different zenith angle, propagation distance, coherence of source and outer scale of turbulence on the spatial degree of coherence on the receiver.

This kind of bar codes can be divided into achromatous function ink business card printing and membership card making bar code and non-ferrous function ink business card printing and membership card to make a bar code, the former is commonly used fluorescent ink and thermochromic ink, cyclometalated ink special ink to cards and membership cards produced by the bar code, this invisible bar codes in the business card printing and membership card must be used in making specific illumination, bar code recognition must be enclosed in the sensitive light source, this kind of bar code originally adelomorphic, and on functional inks business card printing and membership cards produced by the bar code is commonly used variable ink to cards and membership cards.

这种条码可以分为无色功能油墨制卡和会员卡制作条码和有色功能油墨制卡和会员卡制作条码，对于前者一般是用荧光油墨，热致变色油墨，磷光油墨等特种油墨来制卡和会员卡制作的条形码，这种隐形条码在制卡和会员卡制作中必须用特定的光照，在条形码识别时必须用相应的敏感光源，这种条码原先是隐形的，而对有色功能油墨制卡和会员卡制作的条码一般是用变色油墨来制卡和会员卡制作的。
