the substitution of a common non-fire-insulation tempered glass with water film for the fireproof glass or overhead door has been proven workable.
其最终目的就是让一般强化玻璃本身能够和防火玻璃一样具有阻热性以及防焰性。
the overhead door is formed by connecting a suspension box, a vehicle door and a drive system.
它由悬挂箱、车门、传动系统三部分连接而成。
this paper sets up the mathematic model of control system according to the analysis of lifting process of overhead door and puts forward a stability stralegy improving control system.
