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。

The calculated NICS values show that nucleus-independent chemical shifts values of roof-shaped isomers for Sb42-, Bi42-, and22- species are all negative, consequently indicating that these roof-shaped isomers possess aromaticities. NICS values for the planar ring isomers are all positive, suggesting that these three planar ring isomers have antiaromatic characters.

A reverse measurement system about the data collecting of 2-D object edge based on machine vision is discussed,in order to realize digital data input of the dimensions of 2-D object complex edge. This system realized calibration in large scene by virtual grid calibration method, and advanced the precision of system by using double CCD cameras. It realized data mergence by setting up referencer of regular shape. Some methods were put forward to realize graphics vectorization such as using eight-chain code difference to search for the turning points, and using change-length subjunctive beeline to distinguish linetype. The output data use the general DXF document format to connect the software of CAD. Research indicated that this system can be applied in reverse measurement to the dimensions of 2-D object complex edge.
