This paper carefully introduce specific numerical method in studing bifurcation and chaos of differential equations. These methods: method of directly observing orbit, stroboscopic sampling method, Poincare section mothod, power spectral analysis method. we give some calculating results and show main strengths and weaknesses of the methods. Though the method is for what said above on the e(?)ample of the forced Brusselater, It's universal.
