two-sided exponential

When the pesticides were applied with rice-hull carrier the dynamics of residual degradation exprespse as two exponential equation reaction.

For the generalized Eady model, two cases were discussed according to the prescribed reference-state density function are constant function and exponential function, respectively. Both nonlinear stability theorem and the condition of the linear criterion coincide with the nonlinear one are obtained.

对于广义的Eady模型，讨论了密度函数是常数函数与指数函数两种情形，分别得到了非线性稳定性定理及线性稳定与非线性稳定一致的条件。

The main contents are as follows: 1. The exponential stability for two classes of criteria Lurie indirect control systems with time-delay are studied in the thesis.

主要研究内容包括以下的几个方面：1.研究了两类具有时滞的区间Lurie间接控制系统的指数稳定性问题。

We deduce the maximum likelihood and Bayes estimates of these parameters when the joint survival function obeys the two dimentions exponential distribution, while in Bayes approach, it is assumed that the unknown parameters have Gammar prior distributions.

在Bayes估计中，我们假定未知参数的先验分布为伽马分布，两章都通过数据模拟对极大似然估计和Bayes估计这两种方法进行了比较。
