将接地长导线源沿导线方向分解成多个电偶极子源，对若干电偶极子源产生的响应进行叠加得到接地长导线源的Hz响应。计算结果表明接地长导线源的Hz响应与电阻率之间的关系也为单值关系。(Decompose the grounded long wire source along the wire direction with several electric dipole, and overlay the response which produced by the electric dipole as the grounded long wire source’s response. The result show that the relationship between the Hz component of ground long wire source and resistivity are also single valued.)

这是一个仿真移动通信信道幅频响应的matlab仿真程序。(This is a simulation of mobile communications channel amplitude frequency response of Matlab simulation program.)

The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform. For Haar transform, the transformation matrix H contains the Haar basis functions hk(x). They are defined on a continuous, closed interval, x -[0, 1] for k = 0,1,2 ...,N -1 where N = 2n.( The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform.
