I once knew someone who spent a year in a plaster cast recovering from an operation on his back.

我曾了解到有人因背部手术而被打上石膏近一年时间。

Setting time of gypsum plaster is very short, usually only 6 ~ 30 min, and operation time is only 5-10 min, which cannot satisfy the practical plastering and construction of gypsum-based material.

半水石膏凝结硬化很快，其初终凝时间为6 ~ 30分钟，可操作时间只有5 ~ 10分钟，往往不能满足石膏基材料的成型与施工的需要。

Methods: Fixing treating the Colles Fracture with wrapping sides plaster, Function exercises at the early period after operation.

方法：用背侧卷边石膏固定治疗克雷氏骨折，术后早期行功能锻炼。

Sledge described the operation generously: the rooms teeming to the scrolled plaster ceilings with bud-heavy green stalks, the floor cabled with sprinklers, the walls lined with foil reflectors to maximize the ripening effects of the solar-spectrum lamps, the stereo chattering NPR talk radio to cover the drone of the daytime light banks, and classical music to give the plants a cultural heritage through the cool damp night.
