假设

These approaches have disadvantages that have too many assumptive conditions, low optimization ability, and don' t consider some questions such as reactive power compensation.

这种方法假设条件较多，寻优能力不强，且对一些问题如无功补偿未加考虑，受个人经验影响比较大。

It is, of course, very hard to assure oneself on the latter point, and if we make this assumption, it must be in the main because we have to admit our almost total ignorance of whether the relevant circumstances are likely to change, and if so, how.

假设后者成立，结论大体上就是这样。因为，我们必须承认，相关情况可能变化，我们却毫不知情。加之，变化一旦出现，我们又该如何？

The former researches on land price, usually treating spatial structure change as astatic one, often use Hedonic Model to depict the spatial variety of the whole studyarea. This research method hypothesized that the error items were dividedindependently and equally.

过去关于地价的研究主要视地价的空间结构变化为静态，多以特征价格方程等方法全域刻画地价空间变化，将误差项假设为独立与相等的分配，这样所得到。

The renowned astrophysicist has said in a Discovery Channel program that it was perfectly rational to assume aliens exist.

这位著名的天体物理学家在探索频道表示，假设外星人存在是十分合理的。

Assuming that the connect and infectious rate is a periodic function, we study the asymptotic behavior of the solution for this model.

在模型中，假设接触感染率为时间的周期函数，研究模型解的渐近行为，得到了疾病传播的阈值。

Describes general methods of hypothesis testing and optimality properties of tests: Neyman-Pearson theory, likelihood ratio tests, score and Wald tests, uniformly and locally most powerful tests, asymptotic relative efficiency of tests.

假设检验和经验的最有性质： Neyman-Pearson 理论，似然比率估计，score 和 Wald 经验，一致最大功效检验，局部最大功效检验，检验的渐进相对有效性。

Basing on this, the formal asymptotic expansion of solution for the original problem is obtained. Finally, under suitable conditions, existence and its uniform validity of asymptotic expansion of solution for the initial boundary value problem are proved,by using theory of differential inequalities.

在这基础上得到了原问题解的形式渐近展开式；最后，在适当的条件假设下，利用微分不等式理论，证明了原初边值问题解的存在性及其渐近展开式的一致有效性。

Under a given assumption, the author of this paper obtained the uniformly powerful asymptotic expansion of M order and made an estimation of the remainder in asymptotic series.

研究拟线性双曲型方程柯西问题，在一定假设下，得到解的M阶一致有效的渐近展开式，并作出余项估计

Under the assumption that the channel state information was available only at the receiver,the capacity of MIMO systems in Rayleigh fading channel was investigated on the basis of information theory. Three special expressions for the MIMO capacity over ergodic flat fading channel were derived.An asymptotic formula for MIMO systems with equal number of transmit and receive antennas in small SNR was also given. Simulation results show that this approximation is relatively accurate.

以信息论的观点为基础，在假设信道状态信息仅收端已知的情况下，采用等功率发射方案，研究了瑞利衰落信道下MIMO系统各态历经信道容量，推导了三种特殊MIMO信道的各态历经信道容量表达式，以及在小信噪比下等收发天线MIMO系统的容量近似公式，并通过仿真进行了验证，仿真结果表明该近似公式比较精确。

Five dimensional asymptotic modal system describing liquid nonlinear resonant sloshing is derived based on Narimanov-Moiseev third order asymptotic hypothesis.

首先利用Narimanov-Moiseev三阶渐近假设关系，推导出描述液体作非线性共振晃动的5维渐近模态系统。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
