The simulative design solves the problems that one must test many times and the optimal design can not be done in empirical design. 模拟式设计方法可解决经验式设计必须多次试验和不能进行最优化设计的问题。
The second type of these models is an empirical rate expression, which rate constants and reaction orders are determined by dealing the experimental results with linear regression. 第二类模式是一种速率的经验式，其中速率常数及反应顺序取决于对实验结果的线性回归的讨论。
