该文研究了局部对称共形平坦空间中具有常数量曲率的紧致子流形，证明了这类子流形的某些内蕴刚性定理。
But for factory structures under great equipment loads, the space work is shown more or less especially when every horizontal frame is different in rigidity.
但是，对于承受一些特定的较大设备荷载的厂房结构，特别是各榀横向平面框架的刚度不同时，在竖向荷载作用下的空间作用有一定的体现。
In order to make reflectors of the space remote sensor keep both high rigidity of structure and fine stability of thermal dimension, a kind of flexible cone-shaped sheath is designed.
针对空间光学遥感器反射镜结构刚度高、热尺寸稳定性差的状况，设计了一种柔性锥套结构，它在保持结构刚度满足力学要求的同时，使反射镜具有良好的热尺寸稳定性。
This paper discusses the space-like submanifolds with constant mean curvature in a pseudo-Riemannian space form, and obtain an integrate inequality and a rigidity theorem.
