When the coil is energized, the iron core attracts the armature and the support plate to move down, and the contact points are turned on or off instantly. The piston rod and the lever slowly decrease due to the influence of the blocking nylon. After a certain period of time, the piston rod decreases to a certain position, and the delayed action contact is pushed by the lever to act, which is in an open state, while the moving contact is closed. The delay time of the relay is the time when the coil is energized until the delay contact completes its action. When the coil is powered off, the relay is restored by the recovery action of the spring.好不容易获得王室认可的Blair（莉顿·梅斯特 Leighton Meester 饰）一方面正燋头烂额地筹备自己和婚礼，一方面又要应付Chuck（爱德·维斯特维克 Ed Westwick 饰）和Dan（佩恩·拜德格雷 Penn Badgley 饰）的示爱。Serena（布蕾克·莱弗利 Blake Lively 饰）在洛杉矶遇到的多年不见的表妹Charlie，并将她带回曼哈顿，却不知道她是冒牌货，并隐藏了一个大秘密。Dan用身边人的故事出版自己小说的《局外人》，成了聚光灯下的焦点，却得罪了所有的朋友。Nate（切斯·克劳福 Chace Crawford 饰）开始在《The NY Spectator》工作，并结识了风韵犹存的Diana，而她似乎知道Chuck母亲的真正身份。在追查的过程中却发现父亲Bart并没有死亡......上东区永远被秘密缠绕，这一次又会带来多大的惊喜？一切都由Gossip Girl来揭晓。毕业后一个人生活也没有找到固定工作，过着无所事事悠闲自在的日子。又立了这样大的功劳……她正美滋滋地想着，忽听严副将军道：你们倒是玩得痛快，如今可苦了我们了。谁能想到，就在大家沉迷于东方不败和令狐冲的虐心爱恋中，《倚天》小说奇峰突起，周芷若瞬间黑化，赵敏不顾一切抢婚。我还在期待黛绮丝成为女主角，和赵敏、周芷若她们来一场轰轰烈烈的宫斗撕逼大戏，没有想到黛绮丝竟然是小昭她妈。
