The modules of the engine system are calculated iteratively in a predetermined sequence,and a modified Newton method is used to find the unknown variables of the system. 该方法按照预定的计算顺序，对发动机系统的各个模块进行迭代计算，并采用拟牛顿法求解系统可调变量。
The designer quickly becomes adept in relating changes in the Laplace domain to behavior in the time domain without actually having to solve the system equations. 设计人员可以很快就熟练地将拉氏域的变化与时域的行为相联系，而不须求解系统方程。
