它也有一个几何曲率。

And also it has a geometric buckling.

由于几何曲率半径和平衡正压力所要求的半径有差别，气泡形状要缓慢地变化。

The bubble shape is changed gently because of the difference between radius of geometric curvature and radius required to equalize normal stress.

有一个术语要在这介绍，称为几何曲率，那与我们在这定义，的材料曲率是类似的。

And there's a term that's introduced here called the geometric buckling which is analogous to the material buckling that we defined there.
