catalyst deposit meaning in English

催化剂沉积

Especially , when - bi together with a little carbon black ( cb ) or copper salt is used , the catalytic effect is better ; the flame structures of the double - base propellants containing - bi are similar to the typical plateau double - base propellant , but the combustion temperature distribution has been changed because of adding the - bi ; and the active components of catalysts deposit on the burning surface of propellants and the quenched surfaces of propellants with various catalysts possess different structure
它与铜盐和少量炭黑( cb )复合后，催化效果更优； 2 , 4 -二羟基苯甲酸铋加入后，推进剂的火焰结构保持了典型平台双基推进剂的结构特征，但改变了双基推进剂燃烧波温度分布，炭黑和铜盐的加入对2 , 4 -二羟基苯甲酸铋的催化作用有很大影响；催化剂分解的活性组分富集在燃烧表面，不同催化剂使推进剂熄火表面形成不同的结构。
