请问材料killed carbon steel怎么翻译和理解? killed steel镇静钢，优质钢，脱氧钢 steel that has been completely deoxidized by the addition of an agent such as silicon or alumimium, before casting, so that there is practically no evolution of gas during solid"ification. killed steels are characterized by a high degree of chemical homogeneity and freedom from porosity. we say the steel is "killed"because it will quietly solidify in the mould, with no gas bubbling out. as a result, killed steel is dense in structure, uniform in composition, and not so segregative as other types of steels. 我们说钢液被"镇静"了，因为这种钢液在钢锭模中平稳地凝固，没有气泡冒起。所以镇静钢组织致密，成分均匀，不像其他铸钢那样偏析。查看更多
用aspen模拟mdea脱硫解吸塔不收敛怎么调试？ 第一，mdea溶液的组成似乎不合理。 第二，亨利组分的定义，n2和so2； 第三，建议使用kemdea物性包。 我是用的kmdea物性包，完善了下流程还是有点问题， block: b10 model: pump * warning mixed substream has zero flow. block bypassed. block: b12 model: fsplit * warning zero feed to the block. block bypassed block: b7 model: radfrac *** severe error a liquid feed/pumparound to the top stage is required when "q1=0" is specified in "col-specs"; required feed/pumparound has zero flow. * warning rest of block bypassed due to severe error. 易水风 于 2013-12-19 11:46:06 补充以下内容: 查看更多
