charring layer meaning in Chinese
炭化层
Examples
- Finally , the numerical technique was used to investigate influence that different parameters on ablation rate . the relationship between oxygen percentage , pressure , depth of charred layer and ablation rate were obtained
最后计算了不同参数对材料烧蚀率的影响,得到了烧蚀率随富氧含量、试验段压强以及炭化层厚度变化的趋势。 - Because thermal insulation was in oxygen - riched condition of afterburner and charred layer was porous , oxygenous gas in mixture would penetrate into charred layer and chemical reaction would take place in whole charred layer , which intensified the ablation process
由于绝热层处于二次燃烧室富氧的环境中,而且炭化层为疏松多孔状物质,因此将化学反应引入到整个炭化层中。 - By investigating the specialty of functions in the expression , the following conclusion was drawn : particle concentration was the dominant factor that enforced ablation , and angle contributed to ablation via cutting the char layer
通过分析关联式中各项函数特性,得到粒子聚集浓度是影响烧蚀量的主要因素,而角度对于烧蚀量的贡献主要体现在对绝热层炭层的剪切破坏上的结论。 - The ablation process in oxygen - riched condition was explored and a physical model was established . electron microscope scanning showed that thermal insulation would form three layers during ablation , namely , primitive material layer , pyrolytic layer and charred layer
在实验基础上对富氧烧蚀过程进行了分析,建立了富氧条件下以基体层、热解层、炭化层三层结构为基础的烧蚀物理模型。 - According to the physical model , a mathematical model and computational method were proposed . an axially symmetric transient thermal conduction equation was put forward , which included material pyrolysis , pyrolysis gas flow and chemical reaction in charred layer . chemical reaction was controlled by chemical dynamics , and the reaction rate was computed using arrhenious equation
针对物理模型提出了相应的数学模型和数值计算方法,在材料内部建立了二维轴对称的非稳态导热控制方程,其中加入了材料热解、热解气体流动以及炭化层内的化学反应等因素的影响,化学反应由化学动力学控制,通过arrhenius公式确定其反应速率。
