解决物理学中非对称分布问题时的补偿迭加法

本文提出一种解决普通物理学中非对称分布问题的补偿迭加法,其要点是:对可能变为对称分布的非对称分布采取补偿的方法,使其呈对称分布,以便能够应用普通物理学的基本概念、基本定律和公式,然后再采取迭加的方法,使对称分布恢复到原问题所要求的非对称分布状态。这一方法可使较为复杂的求解过程得以简化。

Foam drainage wave coalescing and its energy evolution

Liquid foam is a dense packing of gas bubbles in a small amount of surfactant solution. Liquid drains out of foams until equilibrium is reached due to the compromise between gravity and capillarity, which greatly affects the stability of foam. Based on a series of work on foam structure and drainage we conducted previously, this paper reports the results on coalescence of an original forced drainage wave at a low flow rate with subsequent drainage waves with higher flow rates. The evolutions of viscous energy and surface energy during the process of coalescence are theoretically analyzed.     

The program structure designing and optimizing tests of GRAPES physics

According to the modularization and standardization of program structure in Global/Regional Assimilation and Prediction System （GRAPES）, the plug-compatible and transplantable regional meso-scale and global middle-range physics software package is established. The package＇s component integrality is comparative with the other advanced models physics. A three-level structure of connecting GRAPES physics and dynamic frame has been constructed. The friendly interface is designed for users to plug in their own physics packages. Phenomenon of grid-point storm rainfall in numerical prediction is analyzed with the numerical tests. The scheme of air vertical velocity calculation is improved. Opti- mizing tests of physics schemes are performed with the correlative parameters adjusting. The results show that the false grid-point storm rainfall is removed by precipitation scheme improving. Then the score of precipitation forecast is enhanced.
