The radial distributions of plasma parameters are very important in plasma physics. If the plasma distribution is axial symmetrical and optically thin

the radial distribution of some physical parameters are obtainded by using Abel inversion from measured integral value along radial direction. The inverted Abel transform is necessarily used to compute the X-ray emission radial distribution and measure the electronic temperature and density through multichannel method in laser produced plasma expeirments. Using the cubic spline function method

the inverted Abel transform is numerically calculated from two typical distribution that are gaussian and off-axial distribution. The simulated results show that this algorithm is high accurate

convenient to compute and easy to program.
