墙体包含聚苯乙烯和玻璃纤维的热隔离，并且在外部空间使用白色玻璃封闭起来。内部表层是一个双侧的石膏板。
The walls contain polystyrene and fiberglass thermal insulation and are sealed externally with white glass. The internal surface is a double layer of plasterboard.
将管道作为隔离体，在外载荷及前述中面应力的影响下，求位移、内力、内力矩。
Take the pipe as an isolator, under the effect of the external load and the mid-plane gravitation mentioned above, the displacement, the internal force and the internal moment can be worked out.
