the higher mole fraction of hydrophobe, the stronger viscosity enhancement effect.
且疏水单元摩尔分数越高,盐增黏效应越显着。
results show that the content of sn influence the surface morphology of electrode. the coating is the densest at a mole fraction of 14.28% of sn.
结果表明,电极的表面形貌受锡含量的影响,当涂层中锡的摩尔分数为14.28%时,涂层最致密;
if we plot this versus xb, this is mole fraction of b in the liquid going from zero to one.
如果我们把它化成xb的函数,这是液相b的摩尔分数,从零到一。
so what「s the mole fraction of b in the gas phase?
那么b在气相中的摩尔分数是多少?
and let」s say the mole fraction of a in each of the liquid and gas phases, right?
我们在液相和,气相中都有a的摩尔分数,对吗?
well it「s the mole fraction of a in the gas.
这是气体中a的摩尔分数。
the highest gasification efficiency reached 109% and the mole fraction of hydrogen in product gas could be in excess of 40%.
气化率最大可以达到109%,气体产物中氢气的体积含量可以超过40%。
and what that means is that, for example, va xa and that」s just equal to xa, the mole fraction of a.
并且它意味着,例如,除以v的值和na除以n相同,va,over,v,is,the,same,as,na,over,n。,它就等于,a的摩尔分数。
so that the vapor pressure of cs2 is related to the mole fraction of cs2 times the vapor pressure of cs2 if it was pure.
所以cs2的蒸汽压2,与cs2的摩尔分数2,和纯的cs2溶液蒸汽压的积成正比。
the pressures over the pure liquid a and b at the limits of mole fraction of b being zero and one.
纯液相a和b的压强,在b的摩尔分数为零和一的极限时的值。
and in terms of the molar fractions, it「s the total pressure squared, times the mole fraction of no2 squared, divided by the total pressure to the first power.
写成摩尔分数的函数,总压强的平方,乘以no2摩尔分数的平方,除以总压强。
so that」s our mole fraction of b.
这就是b的摩尔分数。
and then you have one non-linear relationship there for the mole fraction of the gas.
然后你们会遇到气体摩尔分数,是非线性关系的情况。
modified meta-aramid(pmia) copolymer with tpc mole fraction of 0.05~0.15 was prepared by low-temperature-solution polycondensation in dmac.
采用低温溶液法共缩聚反应合成了对苯二甲酰氯(tpc)摩尔分数为0.05~0.15的改性间位芳香族聚酰胺( pm ia)共聚物。
you decrease the mole fraction of the less volatile material in the gas phase.
更不易挥发的物质,在气相中的,摩尔分数减小了。
then if i take the other limit, 0 where the mole fraction of cs2 goes to zero.
如果我们考虑另一种极限情况,当cs2的摩尔分数趋近于。
so this is the mole fraction of the liquid.
这是液相的摩尔分数。
