al Identity ll Problem of synchronic identity for persons: under what conditions are two simultaneous person-events events in the life of the same person? Problem of diachronic identity for persons under what conditions are two person-stages stages in the life of a single person. In particular, what makes a particular person-stage a continuation of me as I am right now? Background desiderata: an account of personal identity should allow for the possibility of anticipation and memory, i.e., of individual psychological connections between different person stages. It should also allow us to justify our practices of

I.什么是古典概率模型 如果试验E满足 (1)试验结果只有有限种, (2)每种结果发生的可能性相同。 则称这样的试验模型为等可能概率模型或 古典概率模型,简称为等可能概型或古典 概型

5.3实对称矩阵的相似矩阵 目的:对于实对称矩阵A(A=A),求正交矩阵Q(QQ=E), 使得QAQ=A.此时,称A正交相似于对角矩阵A 1.实对称矩阵的特征值与特征向量的性质 定理6a=A→∈R. 证设Ax=x(x≠0),x=(51,52,5n),则有

定义:对于An,若有B满足AB=BA=E,则称A为可逆矩阵, 且B为A的逆矩阵,记作A-1=B 定理1若A为可逆矩阵,则A的逆矩阵唯一 证设B与C都是A的逆矩阵,则有

概述 (一)药物动力学概念及其临床意义药物动力学(pharmacokinetics)亦称药动学,系应用动力学 (kinetics)原理与数学模式,定量地描述与概括药物通过各种途径(如静脉注射,静脉滴注,口服 给药等)进入体内的吸收(Absorption)、分布Absorptonistributo《letabo1sn))、代谢(Metabolism)和排泄 (Elimination),即A.D.M.E过程的“量时”划化或“血药浓度经时”变化的动态规律的一门 科学。药物动力学是一门较年青的新兴药学与数学间的边缘科学;是近20年来才获得的迅速发展的 药学新领域

Introduction Frequency-selective fading is a dominant impairment in mobile communications Fading reduces receive signal-to-noise ratio and degrades the bit-error-rate(BER) Frequency selectivity of the channel, i. e, delay spread, induces inter-symbol interference(ISI) To combat frequency-selective fading
