toroidal

1.Firstly, there are two types of winding patterns for toroidal vessel: spiral winding along toroidal vessel geodesics and analogous sine placement along the external surface of toroidal vessel.

首先，环形容器缠绕要有两种类：沿稳定测地螺旋缠绕和类似正弦外包罗铺放。

2.In this paper by applying the poloidal-toroidal decomposition of a velocity field, Oberbeck-Boussinesq equations are transformed into a new equivalent system.

本文利用速度场poloidal-toroidal分解，把Oberbeck-Boussinesq方程组转化为一个等价方程组。
