苯甲酸铋 meaning in Chinese
bismuth benzoate
Examples
- The results show that : - bi is a good burning catalyst of double - base propellant and possesses an excellent ability to reduce pressure exponent
结果表明， 2 , 4 -二羟基苯甲酸铋是双基系推进剂良好燃烧催化剂，它能显著提高了双基推进剂的燃速，并降低压强指数。 - In order to investigate the effect of 2 , 4 - dihydroxylbenzoate ( - bi ) on the combustion of double - base propellant , the combustion law of the propellants containing - bi was studied by means of the single frame amplification photography fl miniature thermocouple , the scanning electron microscopy ( sem ) and the link isis energy spectrum
摘要为了探索2 , 4 -二羟基苯甲酸铋对双基推进剂燃烧的催化作用，采用单幅放大彩色摄影法、型微热电偶技术、扫描电镜和电子能谱研究了含2 , 4 -二羟基苯甲酸铋双基推进剂的燃烧规律。 - 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。
