Visualization interface program of the model is developed, which can reflect visually the whole adjustment process of irrigation rate, and obtain rational results through convenient interaction between the user and computer.

When the power-law constitutive model is used, even though the flow rate is rather high, the computation can be finished and yield rational results only after finite times of iteration.

The numerical examples indicate that, for the pressure dependent plasticity, the influence of the various stress measures as the argument in the definition of yield criterion is significant, and the formulation in terms of Cauchy stresses leads to the rational results.

It is shown that this method renders convenient calculation,rational results,high prediction precision,and its outcome can provide reference for groundwater exploitation in irrigation area.

2, The contrastive analysis of the calculated results got by in-situ tests and conventional methods proves that FLAC numerical calculated method which produces more rational results is feasible in the designing of double-row piles retaining.

Fuzzy data are usually obtained according to the experience of limited experts,therefore, how to use these limited fuzzy dada to obtain rational results in fuzzy reliability analysis is a problem that should be solved.

The eventual goal is to lift the rational results of Burghelea-Fiedorowicz on the relation of the space of homotopy equivalences modulo homeomorphisms ofM and hermitianK-theory to 1/2-local ones.

By assumption that a circular sliding surface occurs under earthquake, a general computational method for earth pressure is proposed in this paper. Two sets of general formulas for computer use are deduced for the first time, which capable of checking automatically.It is convenient to consider the influence of various factors by these formulas.

By assumption that a circular sliding surface occurs under earthquake, a general computational method for earth pressure is proposed in this paper. Two sets of general formulas for computer use are deduced for the first time, which capable of checking automatically.It is convenient to consider the influence of various factors by these formulas. The static and circular arc assumption adopted in this paper absorbed the rational result of dynamic study, as a result, the distribution of the active earth pressure is closer to the dynamic analysis result obtained by the finite element method.By means of computation of the earth pressure under different intensity of earthquake, the earth pressure of cohesive soil and lines of the resultant under arc and plane assumption have been compared. Finally, a preliminary conclusion is given in this paper.

In this paper,on the basis of the fundamental principle of slice method, a new method for stability analysis is presented,by considering the equilib- rium of moment acting on the slices,and assumptions that the shear strength in the failed sliding faces reached to the limit,and the normal stresses acting on the faces perpendicular to resultant forces distributed in linearity. Some formulas are derived in order to find the values,directions and action points of forces which act on the demarcation faces and bottom...

In this paper,on the basis of the fundamental principle of slice method, a new method for stability analysis is presented,by considering the equilib- rium of moment acting on the slices,and assumptions that the shear strength in the failed sliding faces reached to the limit,and the normal stresses acting on the faces perpendicular to resultant forces distributed in linearity. Some formulas are derived in order to find the values,directions and action points of forces which act on the demarcation faces and bottom sliding faces of slices.In analysis,if the shear stress in these sides is over the limit strength,a proposed method in this paper is used to regulate and redistribute these forces.Through repeated computations,the rational results and the safety factor of stability against sliding can be obtained. An actual example explains the applicability of this method and shows the possiblity of apptication in Engineering design.

Two-year's experiment data using 40 parents of upland cotton (G. hir-sutum L. ) with 14 measured characters demonstrated that the phenotypic mean correlation (Rp) matrix can be used to replace the Rg matrix as the foundation of the distance estimation of the paraents. The former had a good stablity in two years, which character standardizing was rational and was always positive definite matrix. The character can be used in the analysis of phenotypic distance (Dp2) absolutely sameness.During two years,...

Two-year's experiment data using 40 parents of upland cotton (G. hir-sutum L. ) with 14 measured characters demonstrated that the phenotypic mean correlation (Rp) matrix can be used to replace the Rg matrix as the foundation of the distance estimation of the paraents. The former had a good stablity in two years, which character standardizing was rational and was always positive definite matrix. The character can be used in the analysis of phenotypic distance (Dp2) absolutely sameness.During two years, using the Rp had higher similarity of Dp2 and cluster results than the Rg. Compared to the different methods of cluster analysis, the longest distance method had a larger range of the cluster, higher sensitivity, rational result of the cluster and higher using value on the cotton breeding. The authers suggested that using phenotypic correlation matrix (P) -principal components transformation(C)-Euclidean distance(E)-the longest distance method of clustering(L), i. e. PCEL method be the best way for the distance estimation and cluster analysis of the cotton paraents.
