Finally, display quality affected by the factors of brightness, contrast, ambient illuminance, screen glass transmission and black matrix of CRT are studied with the SQRI method.

最后，用SQRI法研究了亮度、对比度、环境光、屏玻透过率以及彩色CRT的黑底对显示质量的影响。

Adjust the brightness of the display screen, the brightness should be 3—4 times as bright as the room; then adjust the clair-obscure, the characters on the salt screen should be 5—10 times brighter than grounding.

调整显示器的明亮度，为整个房间照明的3—4倍；接著调整明亮对比，萤光屏上的字应比底色亮上5—10倍。

The synchrotron radiation light source used in LIGA technique for deep lithography is becoming more and more important because of its unique qualities-(1) high brightness, usually being 10〓~10〓 times of common X-ray light source;(2) good collimate, the angle of divergence of synchrotron radiation light source could be compared with that of laser light source.

由于同步辐射光源具有（1）亮度高，比一般X射线源高10〓~10〓倍，（2）准直性好，辐射张角可以与激光相比的特点，因而，利用同步辐射光源作为LIGA技术中深度光刻光源正日益受到重视。

One blade masks the pulldown while the other blade causes an additional light interruption increasing the flicker frequency to 48 cycles per second - a level that is not objectionable to the viewer at the recommended screen brightness of 16 footlamberts (55 candelas per square meter).

一旦一翼遮住光源，另一翼多产生一次光源中断，使光闪烁频率增加到每秒48次。在银幕亮度为16footlamberts(55烛光/平方米)时，观察者觉察不到光闪烁。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
