Untestable assumptions about the process through which data become missing is always made in the general statistical literature.

一般统计文献中对不完全数据的统计分析方法往往要对产生缺失数据的机制做出假设，比如常见的补值方法要求缺失机制是可以忽略的。

this paper discussed several untestable assumptions which were often used in epidemiologi-cal observational studies,and some paradoxical results that may arise under different assumptions were showed.simpson's paradox and lord's paradox were introduced.assumption of treatment assignment in causal inference of epidemiological studies,assumption of control group in evaluation of exposure ef-fects,and assumption of missing data mechanisms in incomplete data analysis were also discussed.

本文主要讨论流行病学观察性研究中几种常用的假定，介绍simpson's悖论和lord's悖论，逆回归问题，以及在不同假定下可能出现的相互矛盾的结果。探讨流行病学研究的因果推断中处理分配机制的假定，暴露作用评价中对照组的模型假定，以及不完全数据分析中缺失数据机制的假定。

For example, the delay and the unuse it widely are the problems. In this paper, a proxy certificates revocation mechanism is designed based on the Myproxy for grid, which adds the revocation of the proxy to the Myproxy. This mechanism can release the PC by manager of the revocation. When a PC was revoked all of the proxy of it will revoked.

指出了撤消机制存在的延时问题和不容易在网格中应用等问题，根据MyProxy系统设计了一种新的代理证书撤消机制，即在MyProxy系统中增加一个代理撤销层，这个系统允许网格管理系统撤消PC，当一个代理被撤消时，由这个代理所衍生的代理将会同时被撤消。
