可除掉的

During the reaction of alkylation, general contained 0.2%~2.0% butadiene will produce viscous heavy composite materials, which will raise final boiling point of alkylate and decrease octane, what is more, it will react with acid to produce corresponding ester, which will increase the consumption of acid, Therefore, we must remove butadiene by selective hydrogenation, at the same time, it will convert some of 1- butane to 2- butane by isomerization and raise octane of alkylate.

一般含有0.2%~2.0%的丁二烯，其在烷基化反应中，可生成一种分子量很高的粘稠重质迭合物，使烷基化油的干点升高，辛烷值降低，并且它还和酸反应生成相应的酯而加大酸耗量。因此必须经过选择性加氢除掉丁二烯，同时，将部分1-丁烯异构化为2-丁烯，以提高烷基化油的辛烷值。

I think the biggest challenge - aside from not laughing during takes - is taking something seemingly so fanciful as an angel with super-powers dressed as Columbo and making something real and empathetic about him.

最具有挑战性的——除掉不能笑以外——就是让这个穿着可伦坡衣服的天使看起来奇妙一点，让他更真实更能引起观众的共鸣。

If there is old film which is epoxy、coal epoxy、polyurethane coating on the surface, hacking off and cleaning the surface, then brush the coating directly.

B、未失效的旧漆膜，手工难以除掉，若确认是环氧、大漆、聚氨酯等类型，可经过打毛并除去污物后直接涂刷本产品。

Where fingermarks are found, it will be necessary for the investigator to compare them against the ones of persons having legitimate access to the premises so that the traces might be eliminated as having evidentiary value if they prove to be from these persons.

如果发现了指印，检查人员就必须把发现的指印和有权进入房屋的人的指印作比较。如果指印证实是来自这些人的，那么作为证据价值的线索就可排除掉。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
