If your CRT monitor has a refresh rate of 72 Hertz (Hz), then it cycles through all the pixels from top to bottom 72 times a second. Refresh rates are very important because they control flicker, and you want the refresh rate as high as possible. Too few cycles per second and you will notice a flickering, which can lead to headaches and eye strain. 在基于显像管技术的监视器的刷新率是上显示的图像绘制的每秒的次数。如果您的 CRT 显示器的 72 赫兹 (Hz) 刷新率，然后它循环通过的所有像素都从顶部到底部每秒 72 次。刷新率是非常重要的因为他们控制闪烁，并且您希望尽可能高的刷新率。每秒，你太少周期将通知闪烁，从而导致头痛和眼睛疲劳。Televisions have a lower refresh rate than most computer monitors. To help adjust for the lower rate, they use a method called interlacing. This means that the electron gun in the televisions CRT will scan through all the odd rows from top to bottom, then start again with the even rows. The phosphors hold the light long enough that your eyes are tricked into thinking that all the lines are being drawn together. 电视有比大多数计算机显示器的刷新率低。为了帮助调整率低，他们使用一种称为隔行扫描的方法。这意味着在电视显像管电子枪将扫描所有奇数行从顶部到底部，然后再次开始偶数行。荧光粉持有光线足够长的时间你
