This paper consists of two parts,namely,the method of expressing the zonal climaticdata of 500mb height in terms of several parameters and some characteristics of the zonalindex for the Northern Hemisphere obtained by a three-parameter representation.Finally,the results are discussed.

通过对实际资料的分析,作者发现,在0—70°N 地区北半球500mb 气候平均位势高度沿纬圈的平均值,不论冬夏,都可以很准确地用四参数来表示,其误差小于10位势米.对用三参数和二参数表示的情况也作了此较.最后还用三参数计算了逐月的气候平均情况和个别月份逐日的情况,并指出了某些特征.

The horizontal variation of temperature lapse rate being taken into consideration, the author proposes a three-parametric model for weather numerical forecasting.

我们在文献[1]中设计了一套五个参数的变分波函数用来计算了周期表中前面十个原子的能量,所得结果比过去一些作者用四参数波函数所算得的结果为好。我们在过去计算经验的基础上,另外找到了一套特别简单的解析波函数,其形式为 1s电子: φ_1(r)=N_1e~(-μar), 2s电子: φ_2(r)=N_2[(μr)e~(-μr)-Ne(-μar)], 2p电子: φ_3(r)=N_3(μr)cosθe~(-μr), φ_4(r)=N_4(μr)sinθe~(-i-μr), φ_5(r)=N_5(μr)sinθe~(-i-μr),式中的α与μ为变分参数;N_1,N_2,N_3,N_4,N_5为归一化因子;N为正交化系数。μ可用解析法来决定,因而只有一个参数α要由数值法来决定。我们用这样的波函数算出了第二周期元素的正常态原子和离子(共有八十几个原子态)的各电子的各种能量积分值及总能量值,并确定了波函数的最佳参数值。其结果与五参数波函数的计算结果相比,一般相差在万分之一至千分之一的范围内,并比最近有些作者用一种三参数波函数所算的结果还好。根据这些结果,我们还讨论了Slater近似计算法的可靠程度和适用范围。
