速度势

In this paper, the theoretical model of CQI is described in an atom-diatom system in the condition of the molecular beam, based on the first-Born approximation of time dependent perturbation theory, taking into accounts the anisotropic Lennard-Jones interaction potentials. The method of observing and measuring correctly the differential interference angle is presented. The relation between differential and parameter, velocity is obtained. The relation of the integral interference angle and temperature is discussed.

The method uses an implicit iterative scheme with a hyperbolic sine transformation for the matrix potential, takes the advancing front self-adaptive grid, and resolves problem of too much account in calculation to dry earth's surface by fixed grid method. Results indicate that calculation speed is increased greatly and errors are less than by fixed grid method.

该方法使用了水土势双曲正弦变换的隐式差分格式，并采取了自动向下搜索的空间网格形式，解决了干燥地表固定网格计算量过大的问题，同时计算速度大大提高，计算误差小于固定网格法的误差值。

Nowadays, the process and speed of the human industrialization are booming faster and taster, while shortage of resources, labefaction of environment and other ecological problems are becoming worse and worse, at the same time, the conflicts between the economic growth and the ecological labefaction are becoming more and more piercing, while industrial ecology is the key and effective way to resolve them.
