The effect of components including tetracholrophthalic acid, phthalazine and antifoggant with tribromomethyl sulfone groups on photographic properties of FTG materials was investigated in different pH, using polyvinyl alcohol as a hydrophilic binder, in situ formed AgBr as light sensitive component.

本文以水性聚乙烯醇为粘合剂，原位法合成的AgBr作为光敏元，考察了组分四氯邻苯二甲酸、酞嗪以及三溴甲基砜类防灰雾剂在体系不同pH值时对PTG材料感光性能的影响。

Collotyp: A planographic process using gelatine as the sensitized plate coating onto which the image is exposed photographically and without a screen.

珂版：是一种平版印刷。它用明胶作感光版面，不需网片就可以在它上面曝光，造成印纹。这个印刷方法

珂版：是一种平版印刷。它用明胶作感光版面，不需网片就可以在它上面曝光，造成印纹。这个印刷方法一想到即将去西藏考察，他们都感到极度兴奋。

These findings have suggested the development stages at which to transplant cells--for instance, photoreceptor cells need to be relatively more mature than stem cells, according to Thomas Reh, who studies retinal development at the University of Washington.

在华盛顿大学从事视网膜发育研究的Thomas Reh表示，这些发现提示，进行细胞移植--比如感光细胞的移植时，被移植细胞的发育阶段应比干细胞要相对成熟一些。

Photoreceptors in the retina containing lightsensitive pigments capable of initiating the process of scotopic vision.

视网膜中的光感受器，含有能够主导明视觉过程的感光色素。

Purpose To establish a screen film system sensitometric method of X ray scale exposure by changing the distance between focus and film.

目的建立以焦点胶片距离的改变，取得X线阶段曝光的屏片体系感光测定方法。

The newly publish ed ISO Standard for determining the speed of medical X-ray films specifies the u se of X-ray beam for the exposure of the films during their sensitometric tests; though this method is precise,it requires the use of sophisticated equipment an d time consuming operations.

新颁布的测定医用X线胶片感光度的国际标准规定，用X-射线作为感光测定曝光时的光源，此法精确，但所需设备复杂，操作耗时。

It also has steadying air pressure and storing air function that can ensure pneumatic parts steady and reliable performance.

CCD感光技术能抵消堆积在光幕上的粉末，能自动调节工作状态，保证计数的精确性。

There were still debris of disc membrane of rod OS in the subretinal space and there were no synapse terminals in the OPL.

二、供体视网膜感光细胞的早期发育和分化不需要与RPE细胞直接接触。

Automatic control of exposure time, vacuum degree, plate cleaning time and temperature en sures quality of plate dev.of resin plate .It is especially applicable in high resolution sensitizat ion resin printing.

自动控制曝光时间及真空度、洗版时间、烘干时间及温度，从而可以保证树脂的晒版质量，特别适用于制作高网线的感光树脂版印刷版。
