使不能

However,it is difficult for polymer photovoltaics to realize commercialization resulting from the low efficiency.

然而，目前有机聚合物太阳电池的光电转换效率低下，使之不能商业化、实用化。

If you have injury caused by accidents, consult a physiotherapist so that he can come out with a program that will not worsen your injury.

如果您有意外造成的伤害，谘询的物理治疗，使他能出来的程序，将你的伤不会恶化。

For the problem that the suppression of co-channel interference and suppression of noise can't be balanced in signal-to-jamming and noise ratio maximization method for the linear precoding of multiuser multiple-input multiple-output downlink systems, an improved scheme that the term of noise variance is modified as a piecewise linear function is proposed, in which the balance between suppression of co-channel interference and suppression of noise can still be maintained even when the noise variance is a small value through piecewise modifying the term of noise variance, and thus the bit error rate and capacity of the systems are further improved.

针对多用户多输入多输出系统下行链路线性预编码的信干噪比最大化方法中，共信道干扰抑制和噪声抑制不能有效平衡的问题，提出将其中的噪声方差项修正为以噪声方差为变量的分段线性函数的改进方案。该方案通过对噪声方差项的分段修正，在噪声方差的值较小时依然能够保持共信道干扰抑制和噪声抑制间的平衡，从而使系统的误比特率性能和容量得到进一步提高。

However, the ocular of hydraulic systems working condition is bad. It is difficult to obtain the parameter of hydraulic system. The fault of hydraulic system has pilosity nature, uncertainty and disguise. The fault sign and the fault reason of hydraulic system have complex non-linear mapping relations, therefore it cannot use the simple functional relation to describe. This has brought the difficulty for the classics fault diagnosis technology. The intelligent diagnosis technology base on ANN and ES can solove the above problem well and the diagnosis result is more accurate and reliable.

但是，液压系统工作状况直观性差，参数不易获取，故障具有多发性、不确定性和隐蔽性；液压系统故障征兆与故障原因之间存在复杂的非线性映射关系，不能用简单的函数关系来描述，给经典故障诊断技术带来了困难，而基于神经网络和专家系统的智能诊断技术很好的解决了上述问题，使诊断结果更加准确可靠。

Is often missed because pinworm eggs in the anus of the mouth, stool investigation can not be found when the evidence of pinworm infection and make it large.

蛲虫病常被漏诊，因为蛲虫的卵产在肛门口，查大便时不能找到蛲虫感染的罪证而使其逍遥法外。

One class of contracts, in which the plighted faith of the contracting parties was the only material ingredient, they specifically denominated Contracts juris gentium, and though these contracts were undoubtedly the latest born into the Roman system, the expression employed implies, if a definite meaning be extracted from it, that they were more ancient than certain other forms of engagement treated of in Roman law, in which the neglect of a mere technical formality was as fatal to the obligation as misunderstanding or deceit.

喜爱研究的人们在目前所乐于从事的工作，以及答复我们祖先对社会状态起源所持纯理论的工作，是对现在存在和在我们眼前活动的社会进行分析；但是，由于缺少历史的帮助，这种分析就时常退化而成为一种徒然是好奇心的活动，并且特别容易使研究者不能理解和他所习见的有很大不同的社会状态。

LX3 is has too odd a shape, making it not pocketable at all.

LX3是有太多奇怪的形状，使它不能便携的。

The height and shape of funnel should be designed that the shoot blows from the exhaust pipes will not drop on the poop deck.

烟囱高度和形状设计应该考虑不能使排烟管烟灰落到尾楼甲板上。

He didn't make it posthumously to their halls of fame because his name would always remind them of their shame.

他不能在死后进入名人堂，因为达斯勒的名字会时刻会使他们想到自己的龌龊。

The theatrical foundation of this paper is option pricing model. This paper focuses on the Black-Scholes model, details the basic postulation, principle and pricing formula. And it is pointed out that the postulation that volatility is constant can't reflect the varying market volatility. Violation of this postulation will lead to biased pricing results.

期权定价模型是本文分析的理论基础，文中以Black-Scholes模型为主，分析了期权定价模型的基本假设、原理与定价公式，指出波动率为常数的假设不能反映市场波动率的变化状况，对该假设的违背将使定价结果产生偏差，因此，波动率在期权定价中有重要的作用。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
