In this paper, mutual information of sleep EEG sequence is estimated by the method of adaptive partition, and delay time is established by the rule of minimum mutual information. 本文以睡眠腦電序列為實(shí)驗對象，采用自適應單元分割法計算互信息，按互信息極小原則確定延遲時(shí)間。
Compared with runoff division method, the rainfall deduction method is characterized with simple calculation and a reasonable result but without additional NSP monitoring data. 與傳統的徑流分割法相比，降雨量差值法能利用現有水文水質(zhì)資料而無(wú)需增加監測項目，即可對流域非點(diǎn)源污染負荷作出估算，計算過(guò)程簡(jiǎn)單，結果合理。
