归纳了熔液中碳溶胶、CO〓溶胶以及Al〓C〓胶体稳定性的影响因素。（6）根据对熔液中炭阴极湿润和电渗现象的研究，通过界面化学理论和毛细管界面理论的应用，讨论了熔液中炭阴极湿润和电渗机理。研究了熔液中炭阴极湿润角滞后效应产生的原因在于测量时体系的不平衡。推导了炭阴极电渗速率的理论方程。

The thickness of the alloying layer is 80μm in the decarbonizing and then surface alloying, but only 15μm in the surface alloying directly. The content of cobalt which doesn't form carbide doesn't have a great difference in two processes, but that of tungsten and molybdenum make a great difference.

在两种渗金属条件下，表面合金层的非碳化物形成元素Co含量差别不是很大，而强碳化物形成元素W和Mo的含量却有着显著差异，直接渗金属的，表层W和Mo含量几乎为零，而脱碳后渗金属的，表层W和Mo总量最大达到6%左右。

The decarbonizing layer has striking influence on surface alloying.

脱碳后渗金属，渗层厚度达80μm；直接渗金属，渗层厚度仅15μm。

In order to determine the load-bearing capacity, the bearing steel GCr15 was treated by ferritic and composite nitrocarburizing techniques.

为考察氮碳共渗层的承载能力，对GCr15轴承钢进行了铁素体氮碳共渗及其与氧化+抛光+氧化相结合的复合氮碳共渗工艺，首次对铝质材料实施了氮碳共渗处理，研究了表面处理层的摩擦学特性。

The powder method without box and the paste with protective coating.

介绍了固体硫氮碳共渗渗剂两种新的使用方法──不用渗箱的粉末法和带保护层的硫氮磷共渗涂料。

All requirements of high surface hardness and resistance, good toughness and center of all steel products to carburizing.

凡是要求表面具有较高的硬度和耐磨性，而中心具有良好韧性的所有钢制品都要进行渗碳。

Control cabinet main circuit power supply, forcing the heating elements stop working since the power is cut off, The upper switch is used to restrict the height of the movements axis ,it can prevent the movements pumped up too high to cause theelevating screw abscisicing from the gear box.

断渗碳电炉控制柜主回路电源，使加热元件断电停止工作，上边的行程开关则限制升降轴升起的高度，以防升降抽升起过高，升降丝杆脱出齿轮箱。

Before 1949, Beijing has heat treatment furnace, salt dissolved by thermocouples means furnace, quenching and tempering, parts of annealing, normalizing, quenching and tempering, carburizing and etc.

热处理 1949年前，北京已采用电炉、盐溶炉、热电偶等手段进行零件退火、回火、淬火、正火、调质、渗碳等热处理。

Carbon content was raised above VC steel level to increase ease of hardening, some copper added to allow some nickel to be removed, slight amount of molybdenum added to increase hardenability still more, and the cemented thin surface layer used in VC (and in most other, foreign face-hardened armors) was eliminated with no loss of resistance from VC quality.

开始是英国制造，后经授权由日本制造），在VC的基础上，日本人开发了独特的新维克斯非渗碳装甲（这种钢材质量上不如美国，英国或德国1930年后的钢材质量）在一战后建造的战舰上就开始使用，VH就是在这个基础上研制出来的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
