  numerical
The essential dimension is a numerical invariant of the group; it is often equal to the minimal number of independent parameters required to describe all algebraic objects of a certain type.
      
We do this in a setting that closely resembles the numerical analysis setting of Mallat and Zhong and that seems to capture something of the essence of their (practical) reconstruction method.

This paper presents a numerical method to solve plane elasticity problems.By considering the prototype as a lattice plate, approximate relations between the displacements of nodal points and the average strains of lattice lines may be established, and thereby approximate forms for the fundamental equations of elasticity obtained. So as to make the method applicable, the various parameters of reactions, stresses and displacements are provided. Finally, a relaxation technique for the force-distribution method...

This paper presents a numerical method to solve plane elasticity problems.By considering the prototype as a lattice plate, approximate relations between the displacements of nodal points and the average strains of lattice lines may be established, and thereby approximate forms for the fundamental equations of elasticity obtained. So as to make the method applicable, the various parameters of reactions, stresses and displacements are provided. Finally, a relaxation technique for the force-distribution method is proposed and an illustrated numerable example is given.

本文提出了一种弹性理论的近似数值解法。把一个平面弹性体当作网格板,可以近似地推求网格結点变位和网格线平均应变之間的关系。因而可以近似地来表达弹性理论的基本方程。为此,文中給出了反作用力系数、应力系数和位移系数;提出了一个松弛解法——力分配法,并附有算例。

The proposed method presented here is for calculating the hydrodynamic pressures due to elastic vibration of structures. Numerical results so obtained compare favorably with the data of field observations and the current design criteria of many other countries. Design formulas for the computation of earthquake hydrodynamic pressures on gravity dams, arch dams and cylindrical intake towers are given.

本文主要讨论了建议采用弹性振动动水压的基本依据,并用此方法计算的结果与地震动水压的实测资料及现行的各国规范作了比较,论证了方法的合理性,给出了计算重力坝、拱坝和国柱形进水塔建筑物地震动水压力的公式。

In this paper, according to variational principle, eqs.(19)and (20) are proposed to compute head distribution and seepage discharge by the finite element method, which satisfy the general definite solution problem eq. (1) for unconfined three-dimensional unsteady seepage of Darcy's law. It is verified that they are an available numerical approach for analyzing three-dimensional unsteady seepage flow problem with free surface through the computation of a pumping well of unconfined unsteady seepage.

本文根据变分原理,对适合达西定律的无压地下水三向非稳定渗流的一般定解问题式(1)提出了用有限元法计算水头分布和渗流量的公式,即式(19)和式(20)。并通过抽水井算例,证明它们对求解有自由面的三向非稳定渗流问题,是一种可行的数值方法。
