工程技术上所谓的制冷,就是使某一系统(即空间或物体)的温度低于周围环境介质的温度,并维持这个低温的过程,这里所说的环境介质是指自然界的空气和水。制冷与空调设备以流体(气体与液体的总称)作为载能物质,实现热能与其它形式能量(主要为机械能)之间的转换或热能的转移。本章介绍流体的性质、热能与机械能之间的转换规律和热量的传递规律,这些知识是空调技术必不可少的理论基础。

This a full 3-tier dababase application which includes a activex dll project(business objects) and a standard exe(UI). Besides all the database techniques it demonstrates, it also shows how to make MSHFlexgrid a editable grid(with combobox, checkbox, datetimepicker) and how to merge a toolbar for multi forms.

This a very simple Yee algorithm 3D FDTD code in C implementing the free space form of Maxwell s equations on a Cartesian grid. There are no internal materials or geometry. The code as delivered simulates an idealized rectangular waveguide by treating the interior of the mesh as free space/air and enforcing PEC (Perfect Electric Conductor) conditions on the faces of the mesh.

LINEINTRGAL Line Integral in a 2D Vector Field. LINEINTRGAL(X,Y,U,V,C) computes the line integral along the lines given in cell array C. X and Y define the coordinates of a rectangular grid over which U and V are defined. X and Y must be monotonic and 2D plaid as % produced by MESHGRID. X, Y, U, and V must all be the same size.
