The author makes a mathematics model by viscous hydrodynamics and so on theories of the flowing material a and b on the board , and deduces the formulas of the film thickness and perfusion measure . i also analyze the surface tension of liquid , in order to find out the best technical parameters and to control 作者利用粘性流体力学等理论建立了a 、 b混合料在太阳能电池板上流动的数学模型,从而推导出薄膜的厚度和灌注量的计算公式,并对所形成液面的表面张力进行分析,以找出最佳的技术参数,以便对其进行控制。
