查询词典 singe fraction

Through comprehensive comparison,during the growth from 1 age-degree bamboo to 2 age-degree bamboo,density, mechanical strength(except maximum tensile strength etc.),fraction of bundle sheath,cell wall ratio,crystallinity,cellulose content and lignin content increase rate are the greatest.3age-degree bamboo has higher strength,strength and gravity ratio andcrystallinity are the biggest,fraction of parenchyma is small and insect-resistant.2 degree bamboo has the greatest mechanical strength,but its strength andgravity ratio is not the highest and its crystallinity is lower than 3 age-degreebamboo due to its greatest fraction of parenchyma,loss tangent value is thebiggest.Its creep character is not good and is easily eaten by moth.

通过综合比较，竹材从1度竹到2度竹生长过程中，密度、力学强度、纤维束比量、胞壁率、结晶度、纤维素含量、木质素含量等指标增加幅度是最大的。3度竹强度较高，强重比、结晶度最高，薄壁组织含量较小，相对抗虫蛀，材质最好，适合材用。4度竹结晶度下降引起强度的下降，但薄壁组织组织比量最小，相对最抗虫蛀。2度竹力学强度最大，但是强重比并不是最大，结晶度比3度竹低，由于薄壁组织组织比量最大，内耗值最大，蠕变性能较差，同时相对易遭虫蛀。

The invention relates to a continuous method for the intermediate separation of the oxirane produced by the reaction of a hydroperoxide with an organic compound, characterised in that the product mixture generated during the synthesis is separated in a partition-wall column into a low-, middle and high-boiling fraction and the oxirane is taken off with the middle-boiling fraction at the side tap point of the column and the hydroperoxide is taken off with the high-boiling fraction from the bottom of the column.

结果表明，表层沉积物中的Cd和Zn主要以可提取态（即弱酸溶解态、可还原态和可氧化态）存在，其中，Cd在弱酸溶解态、可还原态和可氧化态中的含量分别为35.0%、49.7%和12.9%；Zn在三者中的含量也分别达到了17.6%、16.6%和21.4%。

By taking the effects of Ge fraction and strain on the energy band structure and effective masses into account, the analytical model of the effective densities of states of the conduction and valence bands are proposed, and the temperature and Ge fraction dependence of the effective densities of states are also studied. Following this, the temperature and Ge fraction dependence of intrinsic carrier concentration in strained SiGe layers are analytically calculated. Furthermore, carder freezeout effect and the minority carrier trapping effect of the shallow-level compensated imputities in strained SiGe layers at low temperatures are investigated.
