电介质(Dielectric),就是绝缘体一无自由电 荷,不导电。 本章讨论: 在电场作用下,电介质的电荷如何分布? 电介质如何影响电场? 如何计算有电介质存在时的电场分布? 请关注:电介质和导体在电学机制上的区 别

Epstein-Barr virus (EBV), is the herpesvirus that causes infectious mononucleosis and is associated with a number of cancers, particularly lymphomas in immunosuppressed persons including persons with AIDS EBV is a ubiquitous virus, so common that it has been difficult to determine whether it is the cause of certain diseases or whether it is simply there as an artifact

How p53 and Rb pathway function may be disrupted in cancer cells Components of the pathway which are found altered in human cancers are shown in red on the diagram above p53 and Rb themselves may be inactivated by gene mutation (loss of both copies or also as in familial retinoblastoma and Li-Fraumeni syndrome where there are inherited mutations in one copy of Rb or p53 gene respectively. Alternatively

一、公共政策的产生: 从“个体理性”到“集体理性” (一)个体行为的另一面是通过特定规则加总后呈现出来的统计学意义上的集体行动。集体理性是公共政策活动的机制 (二)亚里士多德说“人天生是一种政治动物”。社会学家把个体选择的社会化取向看作是个类似于自然现象的“社会发生”过程。 (三)以亚当·斯密等人为代表的古典经济学理论
