For 9.6μ band of ozone, theory and experimental results show that the pressure-correction (p/p0)K for optical length ?of absorbing gas is a function of p and u. The pressure-correction f(u, p) = (p/p0)K is determined from experimental results. The mean slab absorptivity Af(u'} and d Af(u'}/du of this band is computed.When u is small, weak line approximation is valid, f(a, p) = 1. The pressure-correction for du' in calculating radiative divergence dFz/du' should be unity, and dAf(u'}/du' approaches a constant...

计算大气中的长波辐射时,吸收气体的光学厚度要作气压订正,一般取气压订正后的光学厚度u′=(p/p_0)~K,对于O_3的9.6μ带,理论分析和实验都表明K是u和p的函数,气压订正可取 u′=(p/p_0)~(K(u,p))=uf(u,p). 我们以Walshaw的实验为基础,求出f(u,p)的囹形,并求出辐射通量及辐射通量散度的计算表。 当u很小时,弱线近似成立。漫射辐射的吸收率A_f=1-exp(-2su/d),K→0。在u→0时,dA_f/du=s2/d为一常量。

This paper presents a finite difference numerical method for calculating view factors of diffuse radiant heat transfer. The method is written as a standard computer program by programming language Fortran.The technology can calculate three-demensional arbitrarily oriented surface-to-surface view factors, including the effects of shading by interfering surfaces and it was assumed that all the surfaces would be quadric surfaces.The accuracy of view factors obtained by the method is about±2 percent, it mainly depends on chosen dependent variable (projected plan) and the size of grid points. In order to show the accuracy, four examples are presented in this paper.

本文提出了漫射辐射换热角系数的有限差分数值计算方法,并用FORTRAN算法语言编写出通用计算机程序。 本方法可计算三维空间任意两个二次曲面之间,具有第三个二次曲面遮挡干扰的平均角系数。 本方法的准确度为±2%以内,主要取决于因变量(投影平面)的选取和格子点大小的确定,为验证本方法的准确度,文中举出了四个例子。

Observations made in 1982-1983 in Beijing indicate that tree and plant planting around the dormitory buildings would reduce direct radia-fion, diffused radiation, general radiation and radiation balance on the earth s surface in summer season. A coverage less than 0.7 is considered; to be appropriate in the residential quarters, thus the total daily solar radiation may be decreased by one third, and radiation balance dropped half as much on the surface ground,
