With electronic controllers used occasionally on normal flourescent lights and usually on one-piece CFL's, extra circuitry is included which converts the 240V AC into DC, then back into AC but at a frequency of around 20 to 30 kHz (20,000 to 30,000 cycles per second), which usually eliminates any perceivable flicker.

在普通荧光灯中安装电子控制器，一般情况下通常在单管节能灯中安装这种电子控制器，并设计专门的电路用来将240V交流电转换为直流电，然后再转换成工频大约为20--30kHz（每秒钟20000到30000周期变化）的交流电。通常情况下，这种电灯能消除所有可视见的闪烁。

Since things fit in such categories typically in degrees, a family-resemblance model may in the final analysis be much more informative, as long as one recognizes that variation in any of the ecological parameters amounts more or less to changing the value of a variable in an algebraic formula and yielding a different language variety as output.

由于这种东西适合于各类典型度家庭模式可在形似归根到底更为翔实、只要承认一个生态参数变化的任何数额或多或少地改变价值变了，产生了代数公式输出为多种不同语言。
