For fans of Broadway and Sondheim, it's hard to imagine getting a better adaptation than this.

对于百老汇和桑德海姆球迷，很难想象得到一个比这更好的适应。

After analyzing the structure of sentences,Tarski found that, it was impossible to define the truth of the calculus of classes directly,but making use of the structure character of sentential functions could give us the approach to escape the dilemma:Firstly,we could defined the concept of satisfaction in sentential functions by means of recursive method;Then,we could regard sentences as a peculiar form of sentential functions;Finally,with the help of the concept of satisfaction,we could defined successfully the truth of the calculus of classes.

通过分析语句的结构，塔斯基发现很难直接定义出类演算语言的真概念，而语句函项所具有的可递归形成的结构性质可以使我们得到脱离困境的办法：先采用递归方法针对语句函项定义出满足概念，然后把语句作为语句函项的特殊形式，借助于满足概念最终可以得到类演算语言的真概念定义。

Eleven of the 15 patients had sufficient myocardial recovery to undergo explantation of the left ventricular assist device a mean of 320±186 days after implantation of the device. One patient died of intractable arrhythmias 24 hours after explantation; another died of carcinoma of the lung 27 months after explantation.

结果：植入左室辅助装置后经过平均320±186天的随访，15例病人中有11例心肌功能得到有效恢复。1例在植入后24小时死于难治性心律失常，另外1例在植入27个月后死于肺癌。

The run-up shot may be more difficult or impossible to get close to the flagstick, as the preferred shot should be rewarded, when possible.

低近球这一击或许更难接近果岭，因为首先的一击更可能得到奖励。

It is incredible that you should have wrung friendliness out of him.

很难相信，你会从他那里得到些友善的态度。

Especially it is not easy to be applied in the open environment where information is incomplete and inaccurate.

因此，很难在信息不完全和开放的实际环境下得到应用。

It also makes kernels huge, complex pieces of software that are hard to enhance without adding bugs.

它也使内核成为巨大而复杂的软件，这就很难做到不增加错误而得到升级。

In order to obtained the six-membered ring compound and a thorough assignment of the spectra, and further to prove that the six-membered ring compound was formed from the hydrogen transfer, the compound N-butyl-4-(N-methylphenylamino)-5-amino- 1, 8-naphthalimide 6 was designed to obtained with N-butyl-4-bromo-5-amino-1, 8-naphthalimide and N-methyl phenylamine as the starting material. However it was difficult to obtain the desired product as the different solvent giving the different products except the desired product.

为了能够得到六元环化合物作为定标的物质及其确切的谱图分析结果，并且为了进一步证明由五元环产物通过氢转移得到六元环产物的正确性，设计用N-丁基4-溴-5-氨基-1，8-萘酰亚胺与N-甲基苯胺反应生成N-丁基-4--5-氨基-1，8-萘酰亚胺6，结果发现这种方法很难实现，选择不同的溶剂会生成不同的产物，却都不是目标产物。

In order to research the degrading efficiency of the hard degradationg organism from coking wastewater by microbe. We used the superjacent sludge as cultivated object. Nutrient fluid was taken from a dining room. Then activated sludge was obtained by cultivation. And then, coking wastewater was used to go on cultivating and separating. The activated bacteria that could degrade coking wastewater were gained.

为了研究微生物对焦化废水中难降解有机物的降解效果，以池塘边上层污泥为培养对象，用米泔水作为营养液进行好氧培养，得到较多的活性较好的污泥复合菌，然后用焦化废水进行培养驯化，分离纯化得到较纯的可降解焦化废水的活性细菌。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
