查询词典 stem

BACKGROUND: Bone marrow mesenchymal stem cells of mice are different from human and rats. The difficulties of culture, sustaining impermanency activity of BMSCs after passage and short-term effect of stem cells tracking limited the study of mice.

背景：小鼠骨髓间充质干细胞培养不同于人及大鼠，培养扩展难度高，传代后干细胞活性保持时间短；又鉴于干细胞本身特点，使现有干细胞示踪方法作用时间短，这些因素均影响小鼠骨髓间充质干细胞的实验研究。

Stem : A stem is that part of the word-form which remains when all inflectional affixes have been removed.

词干是所有屈折词缀被去掉后所剩余的那部分

MRI was found to be a very useful diagnostic measure for brain stem infaction.It could not be diagnosed by CT,but brain stem hemorrhage might be excluded by CT.2.Interverient effect is more than that of non intervenient therapy.

（1）MRI是诊断脑干梗死最有意义的检查，CT不能确诊脑干梗死，但有助于排除脑干出血；（2）介入疗效优于非介入治疗。

The results showed that there were intraspecific differences in plant height and stem diameter of tolerant clones, and plant height and stem diameter of sensitive clones decreased significantly.

结果表明：(1)割手密耐性无性系株高和茎径对UV-B辐射响应具有明显的差异；敏感无性系的株高和茎径显著或极显著的下降。

In order to enhance its resistance to bacterial blightand lepidopteran such as leaffolder, striped stem borer and yellow stem borer etc, we intergessed Xa21 and Bt genes into the genetic background of 93-11 by backcross scheme, combining with molecular marker-assisted selection and phenotypic selection. Through three backcross and two self generations, eight families that have homozygous Xa21 and Bt genes were obtained in the BC3F3 families. Two families show higher recovery percentage of 93-11 even up to 90.59%.

为了进一步提高其对白叶枯病的抗性、同时增加其对水稻鳞翅目害虫（如稻纵卷叶螟、二化螟和三化螟等）抗性，利用常规回交育种方法和结合分子标记辅助选择将Xa21基因和Bt基因同时导入93-11中，在BC3F3家系中筛选到8个家系含纯合的Xa21基因和Bt基因，其中有两个家系与93-11比较其遗传背景的回复率很高，达到90.59%。

The result showed that the biomass of root, stem and leaves of Quercus virginiana were reduced with the increase of salinity and the decline of dry weight of stem and leaves was greater than that of root, which indicated that the aboveground of live oak was more sensitive to salt than the underground which lead to the increase of root-shoot ratio.

结果发现，在经过不同质量质量浓度NaCl处理21d后，随着NaCl质量质量浓度的增加，弗栎植株生长受到抑制，其中茎叶生物量减少的幅度较根系大，表明弗栎地上部生长比地下部对盐胁迫更加敏感，从而导致根冠比增加。

Look at my luffa seedling. Although the size is small, the stem is so thick, while this without 116 is taller, but the stem is thin without the ability to withstand the wind!

"大家看我这丝瓜苗，使用116肥的别看它个头小，你看那茎多粗，而没用的这边虽然个头高，但茎比较细，经不起风吹，风一吹就倒了！"

Take shortcomings,failures,and mockings of others as commonplace and a drive to complete oneself,hold your own opinion over the evalution and disscution divested from others,afterwards sink into the state of eliminate mistakes if any or encourge oneself being not being influenced by the sayinngs of others or having no ideas to do.
