求翻译：提出了一种基于摩擦片的纯机械高楼缓降逃生器，该逃生器不需要外在动力，实现了一种简单、实用、可靠，下降速度稳定、造价较低的救生装置。本高楼逃生器使用摩擦片造成摩擦力来控制缆绳轮转动速度，以此作为逃生器缓降的阻尼系统主要结构，帮助逃生人员从高处平稳下降、安全地到达地面。是什么意思？

Presents a film based on the purely mechanical friction slow down high-rise escape device, the escape does not require external power, to achieve a simple, practical, reliable, down speed and stability, low cost life-saving device. The escape tower uses friction plates to control the cable caused by

A friction-based high-rise slowed down the purely mechanical devices, to escape the escape server do not need to be the driving force, and a simple, practical, reliable, low cost rate of decline has stabilized, the life-saving devices. If you use the high-rise escape caused friction friction wheel s

Proposed one kind escapes based on the friction disk pure mechanical tall building parachute approach, should escape does not need the external power, realized one kind simply, has been practical, is reliable, rate of descent stable, construction cost low life-saving arrangement.This tall building e
