Time relays are divided into two types: on-time delay type and off-time delay type, and their symbols are shown in the following figure. For the power-on delay type time relay, when the coil is powered on, the power-on delay type contact acts after the delay time (the normally closed contact is opened and the normally open contact is closed), and the contact immediately returns to normal after the coil is powered off; For the power-off delay type time relay, when the coil is powered on, the power-off delay type contact acts immediately (the normally closed contact is opened and the normally open contact is closed). After the coil is powered off, the contact will not return to normal until the delay time is passed.Substrate　　飘零的雪花迎来了每年一度的情人节。老皇帝干着急，又不好明着开口用她。Eli苦口婆心地劝说Alicia启动参选州检察官的宣传活动，但Alicia固执地拒绝了。与此同时，Diane考虑以合伙人身份加盟Florrick/Agos事务所，但一场内部危机很可能在她加盟之前就毁掉这家事务所。本季开始的时候，Eli竭力劝说（苦苦哀求）Alicia参选州检察官，但Alicia一直拒绝（你将看到她异常顽固的一面），由此产生了该剧不常见的喜剧效果。System.out.println ("memory shutdown! ");这里朴素安静，远离红尘和喧嚣，没那么多阴谋与诡诈，多好啊。
