The quantitative interpretation of D. C. electric sounding curve is usually accomplished by curve fitting method. The fitting of D.C.sounding curve is nonlinear; therefore, the theory of linearizing the nonlinear subject may be used, and the true value can be approached by iteration method. The procedure is as follows. First, the kernel function of observed apparent resistivity is computed; then, the transformed kernel function of theoretical apparent resistivity is obtained using recursion formula; finally, the summation of the squares of difference between the transformed kernel function and the kernel function is minimi that is to say, we make zero the partial derivative of the summationzed with respect to the electric and geometric parameters of a model. Given the initial model, we can obtain a satisfactory result after the iterations for 1 to 7 times. The example is given of how the automatic interpretation of D. C. sounding curve is made using PC-1500 microcomputer.

直流电测深曲线的定量解释工作通常是用曲线拟合的方法实现的。由于直流电测深曲线拟合问题本身是非线性的,因此,拟合时采用非线性问题线性化的理论,用迭代法逐步逼近其真值。其具体作法是先求出实测视电阻率的核函数,再用递推公式求出理论视电阻率的转换核函数,然后使其二者差的平方和达到最小,即,使得二者平方差的和对模型电性和几何参数的偏导数为零。给定初始模型后,一般在迭代1—7次之后就能达到满意的结果。文中列举了用PC-1500微型机进行直流电测曲线自动解释的实例。

The multiplicative complexity of the two-dimensional discrete Hartley trans(?)m of size 2~n×2~n, where (?) is a positive integer, is determined. Although the transform kernel cas[2π(kp+iq)/2~n] of DHT(2~n;2), is not separable into the product of the transform kernel of 1D-DHT, unlike exp[-2πj(ki+lj)/2~n] of DFT(2~n;2), but DHT(2~n;2)can be transferred into one DHT(2~(n-1);2)and (3/2). 1D odd DHTs by linear congruences and ring structures. The computation of 1D odd DHT can be reduced to a direct sum of CHT's, the core of 1D-DHT. The minimal number of real multiplications necessary to compute a length of 2~n two dimensional discrete Harfley transform over the field Q of rational numbers is 2~(2n+1)-6(~n-1)28. Therefore, DHT(2~n;2) have the same multiplicative complexity as the corresponding real data DFT(2~n;2).

本文研究了长度为2~n×2~n(n为正整数)二维离散哈特莱(Hartley)变换的乘法复杂性。虽然DHT(2~n;2)的变换核cas[2π(kp+lq)/2~n]不象DFT(2~n,2)的变换核exp[—2πj(kp+lq)/2~n]那样可以分离成一维DHT变换核的乘积,但是DHT(2~n;2)可以利用线性同余组和环结构转换成1个DHT(2~(n-1);2)和(3/2)2~n个一维奇DHT.一维奇DHT可以简化为一维DHT的核CHT的直和,在有理数域Q上计算长度为2~n的二维离散DHT(2~n;2)所需的最少实乘次数为2~(2n+1)—6(n—1)2~n—8。所以二维DHT(2~n;2)和相应的实DFT(2~n;2)具有相同的乘法复杂性。

By making use of the Riemann-Hilbert (R-H) transforms, the symmetric transformations for the static axially symmetric SDYM fields are constructed. Relating to an appropriateform of the hroup generators of the R-H transform Kernel functions, the correspondingforms of the field transformations are obtained. It is shown that the model has the symme-tries of Kac-Moody and Virasoro groups and their semiproduct groups.

本文利用Riemann-Hilbert变换构造了静轴对称SDYM场的对称变换。对于R-H变换核函数的群元适当形式,得到了场变换的相应形式,证明了模型具有Kac-Moody群、Virasoro群及其半直积对称群的对称性。
