If the change of step-size is controlled by the value of curvature of integral curve, the result can avoid such an error accumulation.
定步长的缺点在于不管是积分曲线的各个点的曲率如何都取一样的步长,这样肯定会在曲率大的一些点带来比较严重的误差,这种误差将在每一步的计算中积累。

The weakness of fixed step-size is that step-size is not variable regardless the curvature of each point of the integral curve change or not, which will affirmatively bring serious error in these points that the value of curvature is bigger. And, this kind of error will accumulate in calculating process.

In this paper we will mainly study the gauge fixing Yang-Mills heat flow of a principal bundleFor a principle bundle with a compact seme-simple Lie group as its structure group over a compact Riemannian manifold without boundary, the evolutions of the curvature and its higher derivatives under the flow above will be derived, and the energy inequality and the Bochner type estimates will be obtained. Then, the monotonicity formula and the small action regularity theorem can be proved. We will give the locally uniform estimates for the higher derivatives of the curvature.
