摘要：
A plurality of magnetic flux measurement data corresponding to two dimensional grids are obtained, then the magnetic flux measurement data are convoluted to sampling unit functions in x-direction and y-direction to obtain an interpolation function. Magnetic field is illustrated by isomagnetic contour lines based on magnetic flux measurement data and interpolation values which are obtained based on the interpolation function. One of the sampling unit functions is replaced with a differential function thereof to obtain partial differential values of arbitrary points.
