In this paper, taking the downward continuation of potential field as an inverse problem of upward continuation, we obtain a convolution type linear integral equation for downward continuation. Making use of the orthogonal symmetry characteristic of Fourier transform matrix, and combining the principles of singular value decomposition of matrix and generalized inverse, we proposed a stable generalized inverse method for downward continuation of potential field, called wavenumber domain generalized inverse algorithm, which doesn't need the computation for inverse matrix. It resolves the instability of potential field downward continuation of large depth.

本文通过把位场向下延拓视为向上延拓的反问题，得到向下延拓的褶积型线性积分方程，再利用Fourier变换矩阵的正交对称特性，并结合矩阵的奇异值分解和广义逆原理，提出了一种稳定的不需要进行求逆运算的位场向下延拓广义逆方法——波数域广义逆算法，解决了位场大深度向下延拓的不稳定性问题。

Therefore has carried on the next experiment: For the proof slip of paper dry scope migration is but because of receives the earth's attraction the influence to concentrate toward the slip of paper lower part, we have carried on the next experiment, we cut the slip of paper the long strip, then changes the level laying aside, because whether there is can't such slip of paper both sides underneath the space cause the hydro energy downward to concentrate create the experimental result the difference, after the experiment discovered, after has removed this difference, the slip of paper both sides dry need the time is nearly same, but according to above experiment, we arrived following conclusion, the slip of paper dry scope is downward moved from on downward migration because of the slip of paper in moisture content by the attraction attraction, causes under the slip of paperAbove the hydraulic modulus also must be many, above the natural slip of paper falls very quickly on the few water on the evaporation, but under many moisture content need more time can evaporate, causes the slip of paper dry scope most above downward to increase slowly from the slip of paper.

急！！！物理翻译中翻英请帮帮忙於是进行了下一个实验：为了证明纸片〈paper sheet〉乾燥范围的移动〈boundary of drying〉是因为受到地心引力的影响而往纸片下部集中，我们又进行了下一个实验，我们把纸片剪成长条状，然后改为水平放置，这样纸片两端就不会因下方有无空间使水能往下集中而造成实验结果的差异，实验后发现，去除了这个差异后，纸片两端乾燥所需的时间几乎相同，根据以上的实验，我们的到了以下的结论，纸片乾燥范围从上往下移动是因为纸片中的水分被引力吸引而往下移动，使得纸片下面的水比上面还要多，自然纸片上面就少量的水很快就蒸发掉，而下面较多的水分需要更多的时间才能蒸发完，使得纸片乾燥的范围从纸片最上面慢慢往下增加。

In this paper, an iterative approach to potential field continuation from curved surface to plane is proposed. The continuation of potential field data from a curved surface to a plane can be viewed as an inverse problem of upward continuation of plane potential field data, getting a linear integral equation. Through viewing the potential field data on the curved surface as the data on the average elevation plane of the curved surface, then using the wavenumber domain generalized inverse algorithm to downward continue the data from the average elevation plane to a given plane, and a topography correction based on the change of curved surface relative to its average elevation is implemented to the downward continued data on the given plane, finally the downward continued data plane is upward continued to the curved surface.

本文提出一种位场数据曲化平的迭代方法，即通过把位场数据曲化平视为平面位场数据向上延拓的反问题，得到曲化平的线性积分方程，再把曲面上位场数据视为曲面平均高程面上的位场数据，利用向下延拓的波数域广义逆算法把平均高程面上的位场数据向下延拓到设定平面上，再根据曲面和其平均高程面的相对起伏对设定平面上的向下延拓数据进行起伏校正，最后再把所得平面上的位场数据向上延拓得到曲面上的位场数据，并进行迭代。
