Using state observers theory, the drive and response systems are constructed, and then synchronization control of a new piecewise-linear chaotic system is achieved. 利用状态观测器思想构造驱动和响应系统，实现了一个新近提出的分段线性混沌系统的同步控制，并且推导了两个不同初值的系统实现同步的充分条件。
However, we find that the best piecewise-linear-threshold contract is significantly superior to the best linear contract when the agent has a power utility function. 但是，我们还发现，在代理人的效用函数是幂函数的情况下最好的分段线性阈值合同明显优于线性合同。
