Easement curve was introduced, whereby curvature changes steadily form a straight line to the desired radius.
缓和曲线推出，即曲率变化，稳步形成一条直线，以达到预期的半径。

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.
本文研究了伪黎曼空间型中具有常平均曲率的类空子流形，得到了这类空子流形的一个积分不等式及刚性定理。

It also emphasises the calculating method for the radius curvature of the round ladder and discusses the problem of rectifying the form of round ladder in prefabrication.
