The major results were as follows. The classical Gear scheme can provide an accurate solution and it is easy for programming by a computer automatically. The sparse matrix Gear type scheme can also provide an accurate solution but much faster than classical Gear scheme. QSSA,EBI and hybrid schemes can run with much longer time step without sacrificing of accuracy, therefore, much efficiently. If analytical solution is obtained by EBI scheme the accuracy and efficiency are much better.展开更多
