假定

Stochastic volatility model assumes that the conditional distribution of returns is normal during most of the empirical applications.

SV模型在实际应用中大多都假定以潜在波动为条件的收益的分布是正态的，本文分析并比较了正态SV模型和具有厚尾分布，特别是t分布的SV模型。

All were enacted on the assumption that they would confer some immediate benefit on some special group.

因为这些政策的实施都是建立在可以给某些特殊群体带来即期利益的假定上。

A confidence interval is only as good as the underlying assumptions used to construct it.

我们构造的置信区间的质量由假定是否成立决定。

They presuppose that names have meaning and elementary propositions sense; and that is their connexion with the world.

它们假定名称具有指谓。基本命题具有意义，这就是它们同世界的联系。

When assumptions (15.4) and (15.5) hold, one can show that the IV estimator is consistent for b1, after applying the law of large numbers.

当假定(15.4)和(15.5)成立时，可以应用大数定律证明IV估计是b1的一致估计。

The first process is to optimize the geometric parameters of the press, on the assumption that the servomotor rotates at a constant angular velocity equal to that of the constant velocity motor. The second process is to optimize the displacement trajectory of the servomotor based on the results of the first process while keeping the geometric parameter unchangeable.

然后，建立了混合驱动压力机的优化设计模型，并将优化分为两步：第一步，假定伺服电机角速度与常规电机相同的条件下，优化设计出压力机的尺寸参数；第二步，在第一步优化结果的基础上，使机构的尺寸参数不变，优化设计伺服输入运动规律。

Secondly, to relax the hypothesis of constant return to scale and redefine the space of technique sets, the decomposition method of the growth of labor productivity has been improved. Using the corrected decomposition method of the labor productivity's growth, the paper analyzes the drivers of evolvements of regional disparity in labor productivity of manufacturing, perspective on the performance of growth.

其次，在放宽规模报酬不变的假定和重新定义技术集空间后，本文利用改进的增长分解方法，对制造业劳动生产率的增长进行了分解，从增长绩效角度剖析了地区差异演变成因。

In the paper,the theory of production frontiers and its non-parametric measurement ap～proaches are used to figure out the input compressing productivity index,Malmquist productivity index based on the input oriented non-parametric production frontiers .The technology efficiency and thedis～tance function and their nonparametric models anr introduced on the conditions of Constant Return to Scale and input strong disposability The Non-pparametric measurement approaces and the decomposition of Malmquist prisuctibity index are put forward

孙巍文采用生产前沿面理论及其非参数方法，对假定产出确定条件下投入压缩的生产率指数基于投入前沿面的Malmquist生产率指数进行了理论与测度方法研究，通过规模收益不变且要素自由，C，S，前沿面条件下的技术效率，距离函数及其非参数模型的分析，本文给出了基于非参数，C，S，投入前沿面的Malmquist生产率指数的非参数测度模型，并从技术变化和资源配置效率变化两个方面进行了分解

Taking the overall crop yields or overall net profits on the whole planned area to be maximum as the targets respectively, the paper gives calculating formulae of rational irrigation quota in accordance with that the constant term of Y=f is smaller or greater than zero and the water use coefficient of irriga...

分别以整个灌区上的总净收益和总产量最大为目标，在假定仅种植单一作物，且地力及其它因素一致的条件下，给出了与Y＝Y中的常数项a大于或小于零以及灌溉水利用系数随灌溉面积变化与否相对应的作物合理灌溉定额的计算式。

As far as we can find from research, the word Consubstantiation has absolutely no other usage other than to supposedly describe the Lutheran belief regarding the Eucharist.

据我们能够找到从科研，字consubstantiation已绝对没有其他的用途以外，以假定形容路德信仰有关圣体圣事。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
