(to be continued)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.Common language: From company strategy to business strategy to functional strategy, using the same thinking tool and adopting a unified thinking model, everyone has a common strategy description language.　　五个子女个个都有一本难念的生活经。西安的大儿子马建国50岁离异，生活窘迫；上海的二女儿马建春下岗搞传销，家庭生活淡漠无情；重庆的三儿子马建华生活富裕，可是只顾着赚钱，失去了家庭亲情；四女儿马建秋有了外遇；最小的儿子马晓建却因一时误会，误认为自己感染上艾滋…… 　The ICalculator in the figure provides the agreed method,　　尼山书院是享誉江南的士族子弟求学入仕的好地方。杭州太守之子马文才，太原王氏子弟王蓝田等也来到了这里。马文才风流倜傥，学识一流，加上一身出色的骑射功夫，在书院中雄冠群英。他仗着时任太守的父亲和自己的各种优越条件，在学友中聚集一班纨绔子弟，屡与梁山伯、祝英台作对。当山伯品状排名超过他时，竞对山伯痛下杀手；当窥探到英台为女且已爱上梁
