The better technological process now is the step control of carbon potential during carburizing.It can be considered a multi stage carburation.

目前最佳渗碳工艺方法是在整个渗碳过程中对碳势进行台阶式控制，这一过程可以看成是一个多段渗碳过程。

In this paper, the effects of process parameter of brush copperplating on the copper film for prevention of carburization were studied; the relation between the time of carburization and the minimun thickness of copper film for prevention of carburization was established.

研究了用刷镀镀铜防渗碳时的工艺参数对镀层防渗碳效果的影响，及渗碳时间与防渗碳所需的最小镀层厚度之间的关系。

"Inorganic compound Any substance in which two or more chemical elements other than carbon are combined, nearly always in definite proportions, as well as some compounds containing carbon but lacking carbon-carbon bonds (e.g., carbonates, cyanides)."

无机化合物：由两个或更多的碳以外的化学元素组成的化合物，几乎总是对称的，某些化合物含碳但缺少碳－碳化学键。

According to the law of conservation of sample energy during solidification, under the condition of Newton's cooling, the ordinary mathematical equation of cooling curve was analized, and a theoretical method calculating solid phase fractions and latent heat was put forward on the basis of characteristic α value.

在对碳含量、硅含量和碳当量作三维空间投影分析的基础上，根据实验数据回归出了计算铁水碳含量、硅含量、碳当量、磷含量、抗拉强度、硬度和共晶度的数学模型；为了提高对硅含量的测量精度，提出了分段定硅的技术方法。

To address the issue, we analyze the correlation and similarity of the different radii sequence and the different combination sequence with the full- ring-sample sequences, based on 642 δ13C data of cellulose fixed in tree-ring at 8 different radii of two Cryptomeria fortunei tree disks from Mt. Tianmu, a subtropical mountain of China. It suggests that 2 to 4 radii mixture sample is the better and more efficient choice for the tree-ring δ13C analysis. It had better to take samples at obtuse angle with each other when to take samples at two or three radii.

研究利用来自天目山的两个柳杉树盘的多方位的和整轮的碳同位素测试数据（共计642个），通过不同方位和不同方位组合的平均碳同位素序列与整轮碳同位素序列的关系的多角度的考查、分析发现，并不是采样的方位数越多越好，选择2~4个方位采样合并分析树轮稳定碳同位素，既经济方便又能比较好的反映一棵树的δ13C变化过程与趋势。

In order to overcome this problem,purification and impurity removal are adopted for the NHD decarbonization liquid.

NHD脱碳液在循环使用中，容易被氧化成的硫单质和粉尘等污染，造成溶液颜色变黑，脱碳电耗高、管道经常堵赛等一系列问题，为此，采用了NHD脱碳液净化除杂技术对受污NHD脱碳液进行处理。

This indicates that the carbon adsorbed in iron goes twice into solid solution during the process of decarburization.

第一次再溶发生在较短的去碳时间，再溶的碳量较少；第二次再溶发生在较长的去碳时间，再溶的碳量较多。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
