重力感应，三个方向，x，y，z 不同方向不同值-Gravity sensing, three directions, x, y, z different values ​ ​ in different directions

reduces to a standard Hamilton-Jacobi equation. There are several major advantages to this formulation. The rst is that (x y t) always remains a function as long as F is smooth. As the surface  evolves, the curve C may break, merge, and chan
