bi propellant 中文意思是什麼

bi propellant 解釋
雙推進劑
  • bi : 【化學】 ＝ bismuth. adj. 〈美俚〉（在性慾上）對男女兩性都感興趣的。
  • propellant : n. 推進物，推進劑；（槍炮的）發射火藥；噴氣燃料。 high-energy propellant 高能燃料。 work horse propellant 【火箭】通用燃料。
  1. Because the propellant grain is viscoelastic material, the liner and adiabatic layer are also viscoelastic one, the interface debond problem is actually interface crack about elastic - viscoelastic or bi - viscoelastic materials. research about this problem relates to the knowledge of viscoelastic mechanics and interface fracture and combustion. numerical analysis method about interface debond on solid rocket motor is researched in this paper

    由於固體火箭發動機的推進劑藥柱是一種粘彈性材料，襯層和絕熱層也具有粘彈性性質，因此其界面脫粘問題實際上是彈性-粘彈性或雙粘彈性各向同性材料界面裂紋問題，對該問題的研究涉及到粘彈性力學、界面斷裂力學和燃燒學等相關學科。
  2. 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 ）復合后，催化效果更優； 2 ， 4 -二羥基苯甲酸鉍加入后，推進劑的火焰結構保持了典型平臺雙基推進劑的結構特徵，但改變了雙基推進劑燃燒波溫度分佈，炭黑和銅鹽的加入對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，不同催化劑使推進劑熄火表面形成不同的結構。
  3. The results show that : - bi is a good burning catalyst of double - base propellant and possesses an excellent ability to reduce pressure exponent

    結果表明， 2 ， 4 -二羥基苯甲酸鉍是雙基系推進劑良好燃燒催化劑，它能顯著提高了雙基推進劑的燃速，並降低壓強指數。
  4. 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 -二羥基苯甲酸鉍對雙基推進劑燃燒的催化作用，採用單幅放大彩色攝影法、型微熱電偶技術、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劑的燃燒規律。
