解：会处理普通实数字符串同样也要会处理科学记数法的，这里就是让我们干这个，很简单其实，前面用atof后面如果有e或者E用atoi，最后一组合就是答案

The stability of the linear periodic system is determined by it's characteristic exponent. This paper studies how to assign characteristic exponent for linear periodic system. In order to do this, the original system has to be converted to the block controllable form by rotating transform first.

摘要线性周期系统的稳定性完全由它的特征指数决定，该文研究如何配置线性周期系统的特征指数，为了配置特征指数，首先需要用旋转变换将原系统化简成块能控标准形。

The characteristic exponent based on a probabilistic dynamical system is calculated, which provides some useful information on unstable periodic orbits of the chaotic economic dynamical system. An effective controlling parameter is chosen by discussing the sign of the characteristic exponent. Furthermore, the control regions of the parameter variable are proposed. Therefore the controllable domain of chaos in the chaotic economic model can be obtained.
