The retation between the potential and the actual rate of infiltration through the soil in a basin has been approached. And an initial try at transforming one's infiltration volumes into another' s has been made by a mathematical hyperbolic model. It has been indicated obviously that in general case such transformed potential infiltration volume of the rainstormdropping on water sheds varies usually relatively to the covering condition of water basins,the durations of rainfalls or the antecedent precipitation...

The retation between the potential and the actual rate of infiltration through the soil in a basin has been approached. And an initial try at transforming one's infiltration volumes into another' s has been made by a mathematical hyperbolic model. It has been indicated obviously that in general case such transformed potential infiltration volume of the rainstormdropping on water sheds varies usually relatively to the covering condition of water basins,the durations of rainfalls or the antecedent precipitation indexes. The features of this relation are similar or even perfectly same to that of the formulas established on the theory of soil moisture dynamics. This proves that such hyperbolic model is effectual for computation of yield-water, and provides a good condition for generalization of its parameters.

本文探讨了流域土壤入渗能力与实际入渗率之间的关系。同时,以双曲模型为数学工具,进行了将实际的入渗量与可能的入渗量互相转换的初步尝试。结果表明,经过这样的转换所获得一般河流的流域上各次暴雨的可能入渗量,与流域的下垫面条件、降雨历时或表征雨前土壤初始含水量的前期降雨指数,关系相当明显;而且这种关系的特征与建立在土壤水动力学理论基础上的一些计算公式的特征,几乎完全一致。这就证明双曲模型用之于产流计算是可行的;并为产流参数的地区综合创造了条件。

But many facors should be considered when the method is used in field.This paper intends to...

In recent years, the response equation of quadratic surface is adopted to reflect the production function relationship between N, P fertilizer input and yeild in the research of proper application of fertilizers. The analysis from the results of muliple-spot experiments indicated that all the quadratic equations could objectively reflect the actual situation of each spot and the degree of imitative coincidence is good. But many facors should be considered when the method is used in field.This paper intends to approach the following problems for the field experiment of winter wheat under the condition of similar weather and single soil type, the relationship between the linear entry in equations with the livel of the initial nutrient value in soil; the relationship between coefficients of linear and quadric entries in the response equation; the effect of soil nutrient N, P ratio on their interaction and application response; and yield estimate on the basis of soil productivity and cost of fertilizer application recommanded by the response equation.

In this paper, three influencing problems in the analysis of seismic settlement for clays and liquefaction hazard for sands, namely, the FEM mesh division of structure with strip foundation, the initial modulus of soils and the different combination of static and dynamic stresses are discussed. It is pointed out, finally, that although there must be some errors in the testing and calculation process due to various assumptions these unreasonable factors are all compensated in some extent because of the use of...

In this paper, three influencing problems in the analysis of seismic settlement for clays and liquefaction hazard for sands, namely, the FEM mesh division of structure with strip foundation, the initial modulus of soils and the different combination of static and dynamic stresses are discussed. It is pointed out, finally, that although there must be some errors in the testing and calculation process due to various assumptions these unreasonable factors are all compensated in some extent because of the use of modification coefficients.
