Abstract

The limitation of the one dimensional master equation with the mass number of projectlike fragment as the variable is discussed. A twodimensional master equation with neutron and proton numbers of the projectlike fragment as variables is set up， and solved numerically by means of a two step difference scheme to obtain fusion probability. The new equation is suitable for studying fusion reactions with any projectiletarget combination， and can better fit the experimental data， so that it can provide a large probability to choose the reaction system for synthesizing a certain superheavy nucleus. The influence of projectiletarget combinations with different isospins on the crosssections of compound nuclei is studied.
