钢中的碳对超低碳钢的性能有很大的影响，针对鞍钢 ASP 中薄板坯连铸生产超低碳钢异钢种连浇过程中铸坯增碳的问题，通过理论计算和取样分析，对异钢种连浇过程铸坯增碳进行了研究，并对工艺进行改进。

When used carburization and tempering, filling baskets should be designed according to different parts of horizontal

当用于渗碳及回火时，装料筐设计应根据不同工件设计横向和纵向气道，使碳势气氛和热风能均匀通过工件每一点，使工件渗碳层或回火均匀。

Four sorts of sex pheromones that were mixed at different ratios with three kinds of main sex pheromone components of seabuckthorn carpenter moth:-7-tetradecenyl acetate (Z7-14:Ac),-3-tetradecenyl acetate (E3-14:Ac) and-7-tetradecenyl acetate (E7-14:Ac), were experimented in the field. The results showed that four kinds of pheromones all had strong, attractive effects on male moths.

为比较沙棘木蠹蛾性信息素不同配方的诱集效果，该文利用人工合成的性信息素组分顺-7-十四碳烯乙酸酯(Z7-14：Ac)、反-3-十四碳烯乙酸酯(E3-14：Ac)和反-7-十四碳烯乙酸酯(E7-14：Ac)按照不同比例配置的4种配方进行了野外诱集试验。

It is concluded that the diameter direction has worse macrosegregation than the catercorner direction. The strong columnar dendrite leads to positive macrosegregation. The dense crystal structure can reduce the macrosegregation of the billets.

结果表明，径向比对角线方向宏观碳偏析大；连铸坯柱状晶发达，导致中心位置附近出现较严重的碳正偏析；较致密的凝固组织有利于减轻宏观偏析；纵切面上的碳呈周期性分布。

Cementite: cementite is ordered to infiltrate carbon steel surface layer process.

：渗碳：渗碳是指使碳原子渗入到钢表面层的过程。

The research on the conditions of chlamydospore production for the liquid fermentation showed that, the better single factors were oat liquid media, 30℃, 120r/min surge culture, sucrose as carbon source,(NH_4)_2SO_4 as nitrogen source and the ratio of 20 to 1 for C/N. Under the better single factors mentioned above, the largest quantity of chlamydospore, i.e.3.05×10~7spores/ml, was obtained on the 10th day after culture.
