二在上述情况中，有效的脂類為大豆磷脂、粗製雞卵璘脂及其不溶於酒精的部分、油脂酸鈉和油脂酸銨等；溶於酒精的雞卵磷脂和油脂酸鉀，並無作用。

The efficiency of mass transfer in 60% fraction of hole is higher than in 40% fraction of hole. When gas/liquid ratio is lower 10, the efficiency of mass transfer in new sieve baffle tray is higher than in traditional tray.A three-dimensional quasi-single phase computational fluid dynamics program with the RNG- turbulence model is presented for evaluating the performance of the new sieve baffle tray. The special feature of this model is taking into account the influence of heat transfer during the mass transfer and the influence of mass transfer in computing the flow field.

建立了以RNG模型为基础的三维拟单相流模型，该模型与其它研究者所建立的模型的最大进步是，前人在塔板流场的计算中没有考虑传质的影响，并且在传质过程中没有也没有考虑传热对传质产生的影响，实际上在传质过程中，抛开传热来计算和研究传质是不准确的，因为在传质过程中伴随着传热，并且传热和传质是互相影响、互相制约的，本文所建立的传热与传质模型，把传热和传质进行了有效的藕合。

And they end up predominantly in the fine particle fraction in the fly ash duringcombustion.When biomass sample is pretreated by using chemical fractionation method,the content of volatile alkali in fuels decreases clearly and large amount of available C1 andS is also leached.So,during combustion the vaporization amount of alkali reduces and theformation of fine particle fraction in the fly ash is limited.

而当样品在经水洗分离和酸洗分离的化学处理后，燃料中易气化部分的碱金属元素含量大幅减少，大量水溶态或酸溶态的S，Cl等非金属&催化性&元素同时也被分离脱除，从而导致燃料样品燃烧时的碱金属气化量下降，且在成灰过程中向细微颗粒转化的途径也受到较大的抑制。

In this paper we proposed a hypothesis of difference fiber volume fraction and presented expressions respectively. The fiber volume fraction of unit cell is not equal to that of each lamina, which need calculate eachly. The paper also advanced conception of weighted average of three cell's stiffness.

本文提出了差别纤维体积分数的假设，各个纤维束的纤维体积分数与单胞的纤维体积分数并不相等，需要分别进行计算，并分别给出了各纤维束的纤维体积分数计算式；还提出了三单胞弹性模量按比例叠加的思想，并给出了比例计算式，计算出了结果。

Unit fraction concepts: The description problems of language of halves are easier than the problem of symbol of 1/2. Students have the habit to deal with unit of things of all contents. When they face the problem of remaining to divide again, they would by oneself increase or reduce the thing of contents. And students were inclined toward each fraction appearing in the same contexts of assumption of ego to have the same deal of unit. When facing comparing problems could be influenced by intuition rules of Same A — Same B and solving problems incorrectly.

单位量概念的表现：一半语言叙述的问题的表现优於具二分之一符号的问题，较习惯用全部内容物当单位量，面对余量再分问题时会自行增减内容物改变单位量，会倾向於自我假设在同一情境中出现的各个分数具有相同的单位量，面对比较问题时受直观规律Same A─Same B的影响而错误解题。

Students' responses to fraction unit's concepts. About 2.1%~26.1% high graders, the major mistakes were changing and neglecting the object of units. About 19.5%~42.7% high graders were toward to think that each fraction appearing in the same contexts of assumption of ego to have the same deal of unit. When the number of contexts was larger than unit, about 36.2%~40.5 high graders can't throw the un- necessary messages away.

在分数单位量概念表现上，约有2.1﹪~26.1﹪的高年级学童主要错误成因在於改变及忽略单位量的大小；约有19.5﹪~42.7﹪的高年级学童，倾向於自我假设在同一情境中出现的各个分数具有相同的单位量；约有36.2﹪~40.5﹪的高年级学童，内容物个数多於单位量内容物个数的情况中，无法排除多余资讯的干扰。

By considering the influences of initial packing fraction, shear rate and friction coefficient on the shear velocity profile, local packing fraction and coordinate number, we have investigate the mean flow features inside shear granular flows.
