查询词典 specific weight

Granted the weight and the specific gravity of a body, we can calculate its volume.

假设已知一个物体的重量和比重，我们就能算出它的体积。

This law is that,"the specific gravity of any substance is the weight of any volume of it, compared with an equal volume of water."

这条规律是："任何物质的比重，都是其单位体积重量与同等体积的水的重量之比。"

This law is that," the specific gravity of any substance is the weight of any volume of it, compared with an equal volume of water ."

The observation of SEM, EDAX and IR analysis showed that the conformation of MPPE was changed, the surface and section of MPPE were rough and accidented, the specific surface area of MPPE was increased, and magnetic powders, HAP and other additives were separated in polyethylene polymer. The removal rates of Phenol by using PPE and MPPE were 82％, 93％, the removal rates of TOC could reach 78％, 89％ respectively, when the phenol wastewater at 120mg/L concentration was treated with aerated process for 14 hours. The removal rates of Phenol were 85％, 90％, the removal rates of TOC reached 80％, 86％ respectively when the phenol wastewater at 350mg/L was treated for 35 hours. The weight of biofilm formation on MPPE was 64％ and 34％ higher than that on PPE at this two wastewaters.

质量浓度为120mg/L的含苯酚废水在好氧生物填料柱中处理14 h后，PPE和MPPE对苯酚去除率分别为82％和93％，TOC去除率分别为78％和89％；质量浓度为350mg/L的含苯酚废水处理35h后苯酚去除率分别为85％和90％，TOC去除率分别为80％和86％；两种不同质量浓度的含苯酚废水降解后MPPE上微生物挂膜量分别比PPE提高约64％和34％。

Our study designed two pairs of specific primers and cloned two molecular weight of 63ku from Schizaphis graminum, and Rhopalosiphum maize utilizing PCR technique and have done the prokaryotic expression, the main results are as follows:(1)Amplified the Buchnera groEL of Schizaphis graminum, and Rhopalosiphum maize Yangling Biotype at first time all over the world ,and sequenced the full lenghth gene.

本研究设计了特异性引物，利用PCR技术从玉米蚜和麦二叉蚜中克隆出蚜虫Buchnera groEL基因并进行原核表达研究，主要结果如下：(1)从杨凌生物型玉米蚜和麦二叉蚜中在国内外首先扩增出Buchnera groEL基因，测定了全长基因序列，并对相关的同源基因核苷酸进行了比较。

AFM images revealed that as the sputtering time was prolonged, the film thickness increased, the film became compacter, and the specific area of the film also increased, thus, the release rate of silver ions increased, which led to improved antibacterial properties. EDX test results indicated that increase in film thickness led to increase in silver weight percentage per unit surface, causing improved antibacterial properties. Moreover, when the film thickness was 1 nm, the inhibition percentage of Staphylococcus aureus and Escherichia coli were 100%.

结果表明：随着薄膜厚度的增大，样品抗菌性能提高；溅射时间延长，薄膜厚度增大，膜层的致密性改善，单位面积上的银含量增加，膜层表面积增大，银离子释放几率增大，是提高抗菌性能的主要原因；当纳米结构银薄膜厚度为1 nm时，对大肠杆菌和金黄色葡萄球菌的抑菌率均达到100%。

Asymmetric over-introgression of the indica alleles on chromosome 7 and many specific regions on other chromosomes in the japonica genetic background is consistent with the general trend observed in the RIL and F_2 populations of the same cross, suggesting a high genetic load in the japonica gene pool, and japonica genome experienced a very severe bottleneck by artificial domestication.2 Genetic background effect on QTL expression of grain weight and its related traitsGenetic background effect on main-effect QTL and digenic epistatic QTL mapping for GWT and its related traits including GL, GW and GT was dissected by a large set of reciprocal introgression lines and recombinant inbred lines derived from Lemont and Teqing in Beijing environment.

籼粳相互导入具有不对称性，粳稻向籼稻背景的平均导入频率与期望值相仿，相反籼稻向粳稻背景的平均导入频率大大高于理论预期，位于第7染色体和一些其它染色体的特殊区段存在籼稻等位基因的超导入现象，在来自相同亲本的重组自交系和F_2群体中也观察到同样的导入趋势，表明粳稻基因组具有较大的遗传负荷，粳稻品种在人工驯化过程中曾经历过一个非常剧烈的遗传瓶颈。2水稻籽粒相关性状的主效和互作QTL表达的遗传背景效应利用Lemont和特青培育的双向导入系和重组自交系群体，在北京环境下定位影响千粒重及其相关性状如粒长、粒宽和粒厚的主效和互作QTL，分别在特青背景导入系、Lemont背景导入系和重组自交系下检测到影响千粒重及其相关性状的主效QTL分别为33个、27个和13个，互作QTL分别为4个、8个和23个，其中仅有6个主效QTL(QGwt5，QGl1，QGl3b，QGl4，QGw7和QGw8)在籼粳两个不同背景下共同表达，3个主效QTL(QGwt5，QGwt7a和QGt5)在导入系和重组自交系中共同表达，分别占检测到影响这些性状QTL总数的11.1%和4.3%，未检测到在3个背景下相同表达的互作QTL。
