Count

这是一个数组练习，程序的作用是查询一个一维数组（数值型数组）中每一个元素出现的次数，且元素出现的顺序不能改变(This is an array of exercises, the program' s role is to query a one-dimensional array (numeric array) in the number of occurrences of each element, and the element can not be changed in order of appearance)

this source code is use to calculate resister capacitor and inductor

运用格子Boltzmann方法中的伪势模型，模拟胀大平面流道中的两相流动，左边幂律流，右边牛顿流体。得出流动过程中，各个瞬态的结果。(Using lattice Boltzmann method of pseudo potential model to simulate the swell plane channel flow, on the left side of the power-law fluid flow. On the right side of the Newtonian fluid. In the process of flowing, the result of each transient.)

说明：  摩擦力是抵抗固體表面，流體層和材料元件相對滑動的相對運動的力。有幾種類型的摩擦：幹摩擦是一種與之相反的力(friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the)
