查询词典 study group

Based on the molecular topological theory, a modified group dyeing indexL is introduced. It is used in the study of refractive index of the ketones and ethers. Relationship between the refractive index and molecular structure of 57 ketones and ethers is studied by using quantitative structure-property relationship technique. The reasonable molecular modeling equations are obtained by multiple regression for the prediction of the refractive index of ketones and ethers.

在分子拓扑理论的基础上，提出了一个修正的基团染色指数L，运用定量结构－性质相关技术研究了57种酮类和醚类化合物分子的折射率与分子结构间的定量关系；通过多元回归的方法建立了L与折射率的定量结构－性质相关模型。

In this paper the authors study proprieties of certain convolution operators on L and weighted BMO spaces,where G is a locally compact totally disconnected group with a suitable sequence of open compact subgroups.

本文主要讨论了定义在局部紧的全不连通群G上的一类卷积算子在加权L和BMO空间的性态。

In my study, the incidence of acute radiation tracheitis was 53.8% in CRT group, all of them were Ⅰor Ⅱgrade, it was obvious that conformal radiation technique was better and reduced the incidence of it.

本研究中，适形治疗组放射性气管炎的发生率为53.8%，且全部为Ⅰ、Ⅱ级，明显轻于其他两组，可见，适形治疗技术可以明显的降低急性放射性气管炎的发生。

In addition, the author is one of the Transect research group, so this paper regards the Transect as the main object to study Te.

并且作者也参加了该断面的工作，故本论文选择该断面作为研究Te的主要内容。

Therefore, it is necessary to study the load transferring mechanism and the design method of pile group foundations.

Planting density, yield components, agronomic traits, leaf area index and group leaf area duration were analyzed in the study, the results showed that Xundan 20 had long trimness in high density. The high value of leaf areas kept over 60 days, and the effective illumination hours（PAR_Avg≥300mmol/s/m2）were over 780 hours in the whole developing stage.

结果表明：浚单20在高密度条件下维持了较高的整齐度，叶面积高值持续期达60d以上，整个玉米生育期内PAR_Avg≥300mmol/s/m2的有效光照时数达780h以上。

The development speed of gynogenetic embryos was later than that of the control group, and aneuploids were found in this study. The obvious improved survival of trochophore larvae with a peak at 40s UV exposure suggested the presence of a Hertwig effect in the gynogenesis of A. pectinata. When sperms were irradiated for 40s, the cleavage rate was relatively high (51.2%), the developmental rate of D-larvae became zero, and the rate of haploid reached the highest (36.8%).

经紫外线照射的精子受精后所产生的单倍体胚胎发育速度慢于正常受精所产生的二倍体胚胎，各照射组均出现非整倍体。40s照射组中卵裂率达到51.2%，D型幼虫发生率为0，单倍体率最高，达到36.8%，出现"Hertwig效应"。

By Laurie Barclay, MDMarch 27, 2003 A marker for insulin resistance was lower in a group of adolescents that were born prematurely and randomized to an undernutrition cohort, according to the results of a study published in the March 29 issue of The Lancet . The investigators suggest that guidelines advocating nutrition to "normalize" growth in infancy may actually increase adult morbidity and therefore should be changed.

伦敦儿童健康研究院Alan Lucas博士表示，我们的研究结果是否能够普及到足月生产的婴儿仍然需要再做进一步的确认，我们承认早产婴儿与足月生产的婴儿在许多方面都有所差异，尤其是早产本身所引发的医疗问题，不过即使我们研究的结果无法适用於所有婴儿，也仍有大约6%的早产儿发生我们所说的这些状况。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.

其基本内涵可概括为：以确有疗效的中药复方为研究对象，以现代科学技术和传统中医药理论为技术支持，以该复方所治病证的药效响应为评价标准，以优化重组疗效更优的新复方为研究目的。
