加利福尼亚的研究组发现,住院的甲型H1N1病人的中值年龄是27岁,比季节性流感患者的中值年龄低很多。
The California research team found that the median age of hospitalized H1N1 patients was 27, much lower than the median age of seasonal-flu sufferers.
利用该模式函数对另一组NSCAT后向散射系数数据进行海面风场反演,采用最大似然估计确定多个风矢量解,并采用矢量中值滤波消除多解。
This model function is applied to NSCAT data to retrieve wind vectors, with the Maximum-Likelihood Estimator to get a set of ambiguous wind vectors and a vector filter technique to remove ambiguities.
讨论了积分中值定理中间点的单调性、连续性、可导性,给出了一组充分条件,并证明了三个相关定理。
The continuity and derivative of the intermediate point in the Taylor mean value theorem are discussed, and some of their sufficient conditions are presented.
中值滤波较通常的二维视速度滤波更能有效地突出波组特征,分离VSP波场的效果也较二维滤波优越。
Median filtering can highlight wave band better than 2-d velocity filtering does. It also causes a better VSP wave field separation.
