安静闭眼状态，脑梗塞组关联维数和近似熵低于正常对照组（P<0.05）。
D2 and ApEn of reduced significantly the group of cerebral infraction as compared to the group of natural comparison under eyes closed state (P<0.05).
分别对单输出和多输出情况进行了分析，最后得到一个考虑相关的近似功耗估算公式，将熵与电路功耗结合起来能够比较精确地估算电路功耗。
A power estimation formula with correlation of outputs concerned is deduced. The formula sets up the relationship between entropy and power dissipation, and gives an accurate estimation of power.
采用近似熵理论分析得出随着运动负荷的增加，腓肠肌和比目鱼肌的肌声信号的近似熵值随负荷增加而增大。
Compared with gastrocnemius and soleus muscle, gastrocnemius muscle acoustic signal 'approximate entropy increases faster, but soleus muscle acoustic signal' approximate entropy increase more gently.
