1.Later Professor Liu Wen studied the Shannon-McMillan theorem in information theorems[2]-[8] and deviation theorems of non-negative continuous random variables[10]-[11]by using the analytic technique and obtained some strong deviation theorems .
后来，刘文教授把分析方法用于信息论中Shannon-McMillan定理和连续型随机变量的偏差定理的研究，得到了若干强偏差定理。收藏指正
2.Methods 75 effort angina pectoris patients, 47 non-ST-segment elevation myocardial infarction patient and 55 healthy subjects underwent 24 hours Holter monitoring in normal life style . The mean QT intervals (QTm), the standard deviation of QT intervals(QTV), the mean HR intervals (HRm), the standard deviation of HR intervals(HRV), and QT variability index(QTVI) were calculated for every hour during the day and the night .
方法122例冠心病患者(75例劳累性心绞痛患者,47例非ST段抬高性心肌梗死患者)和55例正常对照组,在保持日常生活起居的情况下佩戴12导联动态心电图监测仪,计算机辅助下自动测量QT间期,计算相应时间段的QT间期均值(QTm)、QTV、HR间期均值(HRm)、HR间期变异(HRV)和QT变异指数(QTVI)。收藏指正
3.(5) As for a complex stock market, the standard deviation and the beta coefficient are not good risk measurements. Instead, the non-linear variable ,H exponent is a good replacement for risk measurement.
(5) 在复杂性的分析框架下，我们认为复杂资本市场的风险不能用标准差，贝塔系数衡量，非线性变量H指数是一个较好的代替。收藏指正
