　　在电场中任一点处，取一块面积元，与该点场强的方向相垂直，我们把场强大小与面积元之乘积，称为穿过该面积元的电通量，用表示，即=根据电力线数目和电场强度之间的关系：这样，我们把穿过电场中任一个给定面积S的电通量就可以用通过该面积的电场线条数来表述。　　电动机输出功率很低时，所消耗的有功功率，但是所需要的无功功率基本不变，所以无功功率所占比例增大，电动机的COS￠就更低，甚至低于0.5。因此，对于发电厂来说，就必须在输出有功功率的同时，也输出无功功率，在输出的总功率中，有功功率和无功功率各占多少，不是决定于发电机，而是取决于负荷的需要，即取决于负荷的功率因数。　　最小负载电流（单位：mA）：固态继电器执行规定工作所必须的最小负载电流。它一般与最大负载电流一并作为“工作电流范围”列出。最大负载电流（单位：A）：在规定的环境温度下，固态继电器的最大稳态负载电流能力，它还受散热器和环境温度条件的散热限制。

　　 造成非辐射复合(产生热量)，从而降低LED的内量子效率,温度升高导致芯片的蓝光波峰向长波方向偏移，使芯片的发射波长和荧光粉的激发波长不匹配，也会造成白光LED外部光提取效率的降低,同时随着温度上升，荧光粉量子效率降低。

　　2．电气性能校验及：a.动作电压：在70％额定电压下冲击地加电压于继电器线圈，此时继电器应可靠地动作，若动作电压过高，应检查塔形弹簧弹力是否过强，唧子在黄铜管内是否较大，瞬动动合触点压力是否过大，应瞬动触点压力，以便达到动作电压。

 　　根据线圈中电流的大小而接通和断开电路的继电器称为电流继电器。使用时电流继电器的线圈与负载串联，其线圈的匝数少而线径粗。常用的有欠电流继电器和过电流继电器两种。欠电流继电器：电路正常工作时，欠电流继电器吸合，当电路电流减小到某一整定值以下时(10％～20％IN)，欠电流继电器释放，对电路实现欠电流保护。　　交流器工作原理：当电磁线圈接受指令信 得电后，铁心被磁化为电磁铁，产生电磁吸力，当克服弹簧的反弹力时使动铁心吸合，带动触头动作，即常闭触头分开、常开触头闭合；当线圈失电后，电磁铁失磁，电磁吸力消失，在弹簧的作用下触头复位。
