工程技術(shù)上所謂的制冷,就是使某一系統(tǒng)(即空間或物體)的溫度低于周圍環(huán)境介質(zhì)的溫度,并維持這個(gè)低溫的過(guò)程,這里所說(shuō)的環(huán)境介質(zhì)是指自然界的空氣和水。制冷與空調(diào)設(shè)備以流體(氣體與液體的總稱)作為載能物質(zhì),實(shí)現(xiàn)熱能與其它形式能量(主要為機(jī)械能)之間的轉(zhuǎn)換或熱能的轉(zhuǎn)移。本章介紹流體的性質(zhì)、熱能與機(jī)械能之間的轉(zhuǎn)換規(guī)律和熱量的傳遞規(guī)律,這些知識(shí)是空調(diào)技術(shù)必不可少的理論基礎(chǔ)。

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.
