  • 例句與用法
  • The results show that : - bi is a good burning catalyst of double - base propellant and possesses an excellent ability to reduce pressure exponent
    結(jié)果表明, 2 , 4 -二羥基苯甲酸鉍是雙基系推進(jìn)劑良好燃燒催化劑,它能顯著提高了雙基推進(jìn)劑的燃速,并降低壓強(qiáng)指數(shù)。
  • 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
    摘要為了探索2 , 4 -二羥基苯甲酸鉍對(duì)雙基推進(jìn)劑燃燒的催化作用,采用單幅放大彩色攝影法、型微熱電偶技術(shù)、掃描電鏡和電子能譜研究了含2 , 4 -二羥基苯甲酸鉍雙基推進(jìn)劑的燃燒規(guī)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
    它與銅鹽和少量炭黑( cb )復(fù)合后,催化效果更優(yōu); 2 , 4 -二羥基苯甲酸鉍加入后,推進(jìn)劑的火焰結(jié)構(gòu)保持了典型平臺(tái)雙基推進(jìn)劑的結(jié)構(gòu)特征,但改變了雙基推進(jìn)劑燃燒波溫度分布,炭黑和銅鹽的加入對(duì)2 , 4 -二羥基苯甲酸鉍的催化作用有很大影響;催化劑分解的活性組分富集在燃燒表面,不同催化劑使推進(jìn)劑熄火表面形成不同的結(jié)構(gòu)。
