In this paper I have strictly derived these formulae about Landau Diamagnetism by using the theory of statistical mechanics of ideal Fermi system and Laplace transformation.

The paper gives disperse pattern of Laplace functor under in-uniform grid, which fulfills acceptance character and error minimum theory, extremes value principle.
在一个不规则网络上离散拉普拉斯算子的差分格式，不但能满足相容性及极值原理，而且还具有误差极小性质。

In traditional theory of signal and system, the relationship between single side Laplace transformation and Fourier transformation exists faults. The theory from this paper overcomes these faults.
