无法研究的

We have found through the research that rentseeking problem can't be resolved by the noneconomic means only such as system, law, education, etc.

通过研究发现：单靠非经济手段无法完全解决政府采购中的寻租问题，只有通过经济手段和非经济手段双管齐下方能成功。

Don't have to, may be, but by golly you do, and are every bit as anxious about just acknowledgment of priority as the man next door, and just as obsessional and wrapped up in your work, too.

哈，不必竞争，也许是吧，但是无论如何你会竞争，当你得知隔壁那个男同事比你遥遥领先时你一样会焦虑，而且你的研究工作同样会占去你大部分精力和时间无法脱身。

In this paper, a method of weights selected rationally is presented, provided that objective priority level is impossible to be determined by the previous experience.

研究了目标优先级无法凭经验确定条件下多目标决策问题，提出了一种合理选择权重的方法。

As an often used physical model with good theoretical and practical values, StreeterPhelps model has been widely used to study water quality. However, in some special water areas the utilitization of StreeterPhelps model has some limitation as confirming reaeration coefficient often comes from tests in rivers with fast water flow speed with no consideration of wave effects. Furthermore, in practical research in Three Gorges Reservoir, the changing rule of COD appears abnormally. In some water areas far from pollution source, the value of COD changes with time, but does not follow the exponential attenuation rule. This phenomenon can not be explained by former modified StreeterPhelps model.

StreeterPhelps模型是目前进行河流水质研究常用的物理模型，具有良好的理论和实用价值，然而在某些特定水域，该模型的应用受到限制，主要原因是复氧系数的取定多在水流速度较大情况下得到的，而未考虑水面波动对复氧系数的影响，另外，在实际研究过程中发现三峡库区COD变化的规律出现异常：在离排污口相当远的水域，COD随时间变化趋势并不是指数衰减，而是在某个常值附近微小摆动，以往很多修正过的StreeterPhelps模型都无法解释这个现象。

Some troubles emerge when we use regression estimator in such a case:in a continuous survey research,when the prior sample and the present sample are independent and they have different elements,we can not compute the regression coefficient.

作连续调查研究抽样时经常用到回归估计。如果前后两个样本相互独立，并且它们所包含的元素不同，就无法直接计算出回归系数。

The empirical results show that the self-adjustment mechanism can not rectify the disequilibrium of balance of payments of china.

实证研究结果表明，自动调整机制无法纠正国际收支的失衡。

Because the TaAl alloy can't stand the high temperature (630℃) of thermal fusion bonding, this study carries out a low temperature (180℃) bonding method. The device fabricates successfully by using PDMS as the intermediate layer between two substrates.

在晶片制作过程中，因铝化钽合金无法承受热融合接合时的高温(约630℃)，然研究发现采用聚二甲基矽氧烷为中间层时，可成功於低温(约180℃)条件接合并制作出所需晶片。

"They have been no specific studies because you can't really teat it in a lab or field setting,"he told reuters.

他对路透社记者说："目前还没有这方面的专门研究，因为你无法在实验室里或实际环境中进行真正的誓言。"

But, since continuwhichley life part of - studies too is uncapable to conquer, what but lso can do?

但，既然连人生的一部份——研究也无法征服，还能做什么呢？

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
