例句与造句
- The mechanical properties of improved double-base propellants enabled one to envisage grain geometrics with large combustion areas and consequently high thrusts .
经过改进的双基推进剂的机械性能使我们能够指望获得大燃烧面的药柱几何形状，从而得到大推力。 - 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。 - It's difficult to find double-base propellant in a sentence. 用double-base propellant造句挺难的
