分数

If it's too low, you'll have problems.

如果分数太低，你就会有问题。

Now, I'll get a lower grade in the class.

我一定会是班上分数比较低的。

Think of elementary school when you had to reduce fractions to the lowest common denominator.

您应该还记得在小学简化分数时用到的"最小公分母"定律吧。

A higher standard instead of falling to the lowest common denominator,

更高的标准，而不是降低到最小公分数，

It was synthesized by epoxidation of maleic acid with hydrogen peroxide,and the synthesis was carried out in an aqueous solution containing 75% volume of alcohol and over sodium tungstate dihydrate catalyst.

以Na2WO4.2H2O为催化剂，在体积分数为75%的乙醇中用H2O2氧化马来酸，进行了顺式环氧琥珀酸氢钠合成的实验。

The result showed that the fermentation ability and survival ratio of BY-03 and FY-03 remained at about 40% and 60%, which was obviously higher than commercial yeast after freezing and kept up at -20℃ for 4 weeks. BY-03 and FY-03's maltase ability were respectively 10. 12 and 15.10u/g, which were higher than commercial yeast, and BY-03 and FY-03's sugar tolerance were also better than commercial yeast under 0%-4% sugar.

实验结果表明，-20℃下冷冻4周后BY-03和FY-03的发酵力保持在40%以上，存活率在60%以上，明显高于市售普通酵母；其麦芽糖酶活力分别为10.12和15.10u/g，高于普通低糖酵母和普通高糖酵母；且在蔗糖质量分数为0%~40%的条件下生长良好。

We try to get students' mark up high.

我们想方设法提高学生的分数。

It is not an ideal mark in my opinion...

这在我的眼里，并不是一个很理想的分数啊。。。

This is the last chance to make our mark .

这是最后的机会得到分数。

It was the first time for me to get such a low mark.

这是我第一次考了如此低的分数。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。

You were hired to drum up new business, so go and do it.

公司雇你招徕新业务，你就做你的事好了。
