A method for eliminating the internal oxide structure in the gas-phase carbon-nitrogen osmosis of gear features that the CCL4 is added to the kensene as carburizer and then is decomposed to generate Cl2 for reducing the oxide, the ammonia gas as nitrizing agen passes through the cylinder of silica gel or granular calcium chloride for adsorbing residual water vapour and then through the cylinder of 5A molecular sieve for adsorbing residual O2, and the resistance wire is wound on igniting pipe at furnace top to prevent the NH4Cl in exhausted gas from being condensed.

本方法采用在气体渗碳剂煤油中，加入6～8％的CCl 4 ，使共渗炉内的CCl 4 分解出新生的Cl 2 ，使已形成的合金元素内氧化物还原；在渗碳剂氨气入共渗炉前，先经过硅胶瓶或桶及粒状氯化钙瓶或桶过滤，吸附掉氨气中的残留水蒸汽，再经过5A分子筛瓶或桶吸附掉氨气中的残留氧；在靠近炉顶位置的点火管周围缠绕带瓷环的电阻丝，靠电阻丝的副带加热，使排气中的NH 4 Cl不冷凝结块等措施实现内氧化组织的消除。

However, we measured the vapour pressures of dipropyl ether (1) and 1-propyl alcohol (2) up to about the normal boiling point of the respective pure components, which are lower than the 2-ethoxyethanol (3) boiling point.

然而我们测得二丙醚(1)和1－丙醇(2)的蒸汽压分别达到了各自正常情况下的沸点，这比2-乙氧基乙醇(3)的沸点要低的多。

So, to avoid excessive extrapolations of the Antoine equation for the two more volatile components (dipropyl ether and1-propyl alcohol), we have decided to use in this work other equations to estimate these vapour pressures which are applicable in a larger temperature range.

因此，为了避免安托万方程对这两种挥发性更强的成分(二丙醚和1－丙醇)的过度计算，我们决定在本工作中用其他的适用于更大温度区间的方程来估计它们的蒸汽压。

In this study, the vapour–liquid equilibria behaviour of the binary systems dipropyl ether + 2-ethoxyethanol and 1-propyl alcohol + 2-ethoxyethanol and the ternary system dipropyl ether + 1-propyl alcohol + 2-ethoxyethanol was experimentally investigated with the aim of testing the feasibility of using 2-ethoxyethanol as an entrainer to the extractive distillation.

本文研究了2种二元体系（1：二丙醚+ 2-乙氧基乙醇；2：1-丙醇+ 2-乙氧基乙醇）和1种三元体系（二丙醚+ 1－丙醇+ 2-乙氧基乙醇）和的气液平衡行为，旨在测试2－乙氧基乙醇是否适合作为萃取性蒸馏的共溶剂。

I am assuming that the reader is familiar with the difference between 'Contrails'; that is condensation trails left behind highflying aircraft, consisting of water vapour that fades away within a few minutes, and what has become known as 'Chemtrails', also from highflying aircraft, that persist across the sky for some considerable time and evolve into wispy longitudinal clouds.

我假设读者熟悉的区别' contrails '，这就是凝结尾，留下highflying飞机，其中包括水蒸汽即褪色的距离内数分钟，并已逐渐称作' chemtrails '，也从highflying飞机，即坚持跨越天空，为相当长的一段时间，并演变成wispy纵云。
