丁烷

Meanwhile, experiment with the ternary mixture of methanol, butyl methyl ether and 1-chlorobytane showed that the system was not ternary azeotrope and can be separated by combination of extractive and rectification using water as extractive solvent.

针对甲醇、甲基正丁醚和正氯丁烷三元混合物，研究了该物系的性质，得到该物系不是三元共沸物的结论，并用水作萃取剂，通过实验验证了利用萃取和精馏耦合的方法分离该物系的可行性。

Looked closely at microscale experiment and introduced how to use butane blowlamp as a heat source to carry out high temperature microscale experiment by the sample of cracking alkenes.

进一步审视了微型实验，并以烷烃裂化实验为代表，介绍了如何将丁烷喷灯作为热源进行高温微型实验。

To understand why, we'll have to explain a bit about aerosols and butane chemistry.

想要知道原因，我们就得介绍一些气雾剂和丁烷的化学知识。

All that for a $6 butane torch?

所有这些为600丁烷火炬？

It never occurred to me but butane is an ingredient found in some lighter fluids.

我从没想起来丁烷是一些打火机油的成份之一。

While Butane is an ingredient found in lighter fluid, that is not the only thing it can be used for.

丁烷虽然是打火机油的成份之一，但这不是它的唯一用途。

Either of two butyl alcohols derived from butane and used as solvents and in organic synthesis.

丁醇由丁烷制得的两种丁醇的任何一种，用作溶剂和用于有机物的合成

Will have a normal temperature and pressure can not be a large number of liquefied gas - methane to butane.

的过程中，会产生大量常温常压不能液化的气体——甲烷到丁烷。

When you press the button, pressure is reduced and butane comes rushing out.

当你按按钮时，压力减少，丁烷流出。

There are a number of different types of fuel available, including propane, butane, dual fuel, and kerosene.

有多个不同类型的燃料可用，包括丙烷，丁烷，双燃料和煤油。

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。
