Dr Perelman proved Poincaré's conjecture by taking an equation normally used to model heat dissipation in three-dimensional objects, known as Ricci flow.
佩雷尔曼博士利用广为人知的“瑞奇流（Ricci flow）”这样一个热方程来证明了庞加莱猜想。
The equation smoothes out the irregularities of an object, transforming it mathematically into something that looks like a uniform three-dimensional sphere.
这个方程能消除物体间的差异，并能把物件精确的变形为一个统一的三维球体。
At the same time, based on the result, it is concluded that the upwind finite difference scheme for solving the one dimensional heat transfer equation for SG is stable.
同时，根据这个结果分析得到了求解蒸汽发生器一维传热方程的逆风有限差分格式是稳定的。
