4.Monitoring the rim chan-ges with flicker method and monitoring RNFLD with routine method werc compared. For changes of localized damage, 28 cases with rim loss were disco-vered with flicker method, in whom 12 cases were not accompanied by RNFLD changes, while, 17 cascs with RNFLD changes were discovered by routine me-thod, of,whom only did 1 case do not accompanied by rim loss.
用闪烁法对盘沿的监测与常规法对RNFLD监测的比较，对于局限性改变，采用闪烁法有盘沿丢失28例，其中12例不伴RNFLD的改变，而采用常规法有RNFLD改变者的17例，其中仅1例不伴有盘沿丢失。
5.Flicker free drawing (2) - This is a small class that makes it easy to create windows that are updated flicker-free.
这是一个很小的类，可用来方便地创建最新式的无闪烁的窗口。

7.The present study examined the critical flicker fusion (CFF) of spectrallights and white light at different luminance levels. Flicker was produced byintercepting a beam of light with a sector disk driven by a variable speedmotor. Six wavelengths were used, i. e. 440, 460, 540, 560, 640 and 660 nm.
本实验研究了不同亮度级的光谱色光(440,460,540,560,640,660nm)和白光的CFF。
8.She is read by the flicker light of the candle.
她借著闪烁的烛光读书。
9.But the constant value in the Allan variance formula due to flicker phase noise given in some literatures is quite different.
但对闪烁相位噪声所引起的Allan方差公式中的常数,许多文献给出的数值相差很大。
10.In computer graphics, an undesirable pulsation of a display image on a cathode ray tube that usually occurs when the refresh rate is low. Note: for typical displays, flicker occurs at a refresh rate of40 Hz or less.
在计算机制图技术中，阴极射线管显示图象中不希望出现的波动，通常在刷新率较低时出现。注：典型的显示器出现闪烁现象是在刷新率为40赫兹或更低时。
