The horizontal variation of temperature lapse rate being taken into consideration, the author proposes a three-parametric model for weather numerical forecasting. The three parameters are the height of the mean iso baric surface (near 500 mb surface), the temperature of the same surface, and the temperature of 1000 mb surface.

This paper consists of four parts as follows: 1. the flood routing of outflow for basin, 2. the genetic unit-hydrograph, 3. the relation between the three assumptions on unithydrograph and the genetic unit-hydrograph and 4. the calculation of unit-hydrodraph for basin which Iacks data. In this paper the study of the genetic unit-hydrograph is based upon the genetic formulat of runoff founded by M. A. velikanoff and with the help of Muskingum channel storage equation. The calculation of unit-hydrographs by this method only needs three parameters and it is possible to find out the unit-hydrograph without records of hydrometrie observation of river discharge.

本文包括如下四个方面的问题:(一) 流域出流洪水演算,(二) 流域成因单位线,(三) 成因单位线与单位线基本假定的关系,(四) 无资料地区单位綫的推求。四个问题结成一体,以成因单位线为核心。文中成因单位綫公式的推导系以維虽康诺夫的逕流成因公式为基礎,并借用了馬斯京貢(Mnskingum)槽蓄曲线方程式。使用上述公式計算单位线时只需要三个参数,可无需实测流量記录。上述公式又可用來推求无资料地区的单位綫。

In 1955, Hsu Kwang-hsien, Tan Tseng-chen and Wang Chih-pu proposed a new type of trial function—displaced two center molecular orbital for the hydrogen molecule which gives a binding energy of 3.580 ev. for α=1.188 and Rac=Rbd=0.047au. In the present investigation, the configuration interaction of this type of molecular orbital has been used to treat the ground state of H_2. The trial function may be expressed as ψ=[x_c(1)+x_d(1)][x_c(2)+x_d(2)]+k[x_c(1)-x_d(1)][x_c(2)-x_d(2)] x_c(1)=α~/π~(1/2)e~(-αr)cl etc....

This trial function only contains three parameters, namely, the distance Rac=Rbd, the scale factor α and the combination coefficient k. It gives a maximum binding energy of 4.08 ev for α=1.200, Rac=0.035 a. u. and k=-0.61215.
