Based on the hypothesis that constant returns to scale,this paper uses cyclic estimate method of frontier cost function to indirectly...

因此，通过提升技术效率，在要素投入水平不变的前提下，能大幅改善产出水平，这将是辽宁省完成节能降耗指标的主要途径。

The sequence specific assay established in the present study can be used for accurate quantitation of GH mRNA in cyprinid species, and contribute to a better understanding of the regulation of GH mRNA expression in teleosts.

这表明：性类固醇激素不能在转录水平上对生长激素基因表达进行调控，但能够加强促性腺激素释放激素类似物在刺激生长激素分泌及调控其基因转录水平方面的作用。

The results showed the serum IL-2 levels were significantly lower in the patients than that of the controls(P.05),indicated the imbalance of immune functions,The decreased IL-2 levels may decrease natural killer cells and lymphokine-activated killer cells activity,causing reduction of the virus infected target cytolysis may be one of the important reasons in the recurrence of the disease.

结果发现病人血清IL－2水平比对照组明显降低（P＜0.05），说明该病存在免疫功能失调。IL－2水平低下，导致由IL－2诱生的NK和LAK细胞活性降低，使它们溶解和破坏病毒感染靶细胞能力低下，此可能是该病不断复发的重要原因之一。

Does Darwinian selection take place at the level only of individuals, or of groups as well?

达尔文选择是只发生在个体水平上，还是整体水平上呢？

The results showed that the level of LIF mRNA expression of the decidua in abortion group was 0.512±0.219,significantly lower ...

结果发现对照组LIFmRNA表达水平为 1.314± 0 。45 7，病例组表达水平为 0 。5 12± 0 。2 19，两组相比较，差异有极显著性(P 。0 1)。

The next decile down saw roughly 25% growth, and the number of jobs in the lowest two deciles also increased.

接下来的十分位水平的工作大体上增加了25%，同样最低两个十分位水平的工作也增加了。

In this large, international, randomized trial, we found that intensive glucose control increased mortality among adults in the ICU: a blood glucose target of 180 mg or less per deciliter resulted in lower mortality than did a target of 81 to 108 mg per deciliter.

在这个大型的、国际化的、随机试验中，我们发现，强化血糖控制增加了ICU中成人的死亡率：与81-108mg/dL的水平相比，血糖控制在180mg/dL或略低的水平死亡率较低。

Results Punctiform erosion, hemorrhage were observed by nake eyes in each groups. Epithelium cellular necrosis, defluxion, neutrophil being dominant in propria lamina and intact glandular were observed with microscopy. The erosion became severe with the successive stimulate of ethanol. There is no difference between distillate spirit and sodium chloride rats in Guth in 7th day, but Guth in distillate spirit rats was higher than that in sodium chloride rats in 30th day. PGE2, TGF-α contents in gastric mucosa of treated group increased significangly compared with control group. PGE2 showed no difference between each group in 7th and 30th day; TGF-α in gastric mucosa of distillate spirit and sodium chloride rats decreased after 1 month.

结果 茅台组、乙醇组、生理盐水组胃黏膜均肉眼可见程度不同的点状糜烂、出血；光镜下黏膜部分上皮坏死脱落，固有层以中性粒细胞为主炎性细胞浸润，腺体结构基本完整，病变随时间延长有所加重，Guth积分1周茅台组与生理盐水组差异无统计学意义，1月两者相比差异有统计学意义；茅台组、乙醇组胃黏膜组织内PGE2水平与生理盐水组相比明显增高，同时TGF-α表达增强；但PGE2水平各组间1周与1月相比差异无统计学意义；TGF-α表达强度在茅台组、生理盐水组1月后逐渐降低，差异有统计学意义。

Each higher level has a clear and demonstrable function of holding together the level beneath it.

每个更高的水平有一个明确的和明显的功能，总共持有它下面的水平。

What should account for the result is too dense population in city zone, difficulty of employment, environment deterioration and so on.

而我国的城市化水平比较低，已经制约了工业化的发展，我国的城市化现状可以归结为以下几点：①城市化水平低。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
