假定

Proof of unbiasedness depends on our 4 assumptions – if any assumption fails, then OLS is not necessarily unbiased

无偏性的证明依赖于我们的四个假定--如果任何假定不成立，OLS未必是无偏的

On the basis of analysis on the dynamic frequency after power vacancy,the reason of unideal function of traditional device are dissected: it is set by using assumed load and power vacancy.The changed range of real load power and real power vacancy lead to big error.

在对电力系统出现功率缺额后的动态频率特性进行分析的基础上，剖析了传统低频减载装置动作效果不理想的原因：用假定的负荷和假定的功率缺额整定，由于实际负荷功率和实际的功率缺额变化幅度很大，而造成很大的误差。

This essay introduced the method and the empirical results of run test, Dickey-Fuller test and variance ratio test on the efficient market hypothesis. Furthermore, reviewed the volatility test method and empirical result on the EMH which relative to the tests based on stock market return.

摘 要：介绍了市场有效性假定的游程检验，DF检验以及方差比检验的方法和相关实证研究的结果，与以上基于股票市场收益的市场有效性检验相对应，对市场有效性假定的波动性检验方法以及实证结果进行了述评。

The efforts that have been made to explain optical phenomena by means of the hypothesis of a medium having the same physical character as an elastic solid body led in the first instance, to the understanding of a concrete example of a medium which can transmit transverse vibrations, and,at a later stage, to the definite conclusion that there is no aluminiferous medium having the physical character assumed in the hypothesis.

为了解释光学现象，人们曾经试图假定，有一种具有与弹性固体相同的物理性质的介质。这种尝试的结果，最初使人们了解到能传输横向振动的介质的具体实例。但后来却使人们得出了这样一个明确的结论：并不存在任何具有上述假定所认为的那种物理性质的发光介质。
