模拟时钟从0开始，时间单位为0.1秒。人和电梯的各种动作均要消耗一定的时间单位（简记为t），比如：有人进出时，电梯每隔40t测试一次，若无人进出，则关门；关门和开门各需要20t；每个人进出电梯均需要25t；如果电梯在某层静止时间超过300t，则驶回1层侯命。-Analog clock, starting at 0 time of 0.1 seconds. And lift a variety of actions have to consume a certain unit of time (denoted t), For example: someone out of the elevator every 40t test time, the absence of people in and out, and then closed　close and open the door each 20t　each individuals out of the elevator 25t　if the elevator is in a layer of stationary time more than 300t, then drove back a layer Hou life.
