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。It has many advantages, such as the particles size is well distributed, and its diameter can be well controlled, etc. because of this virtue, reverse micelle shows broad prospects in the preparation of ferrite nanoparticles. hi this work, the syntheses of mnfe2o4 nanoparticles, cofe2o4 nanoparticles and znfe2o4 nanoparticles are prepared by the reverse micelle method, these preparations employed reverse micelles formed with anionic surfactant bis - ( 2 - ethylhexyl ) sodium sulosuccinate ( aot ), which is considered the most effective surfactant, and another anionic surfactant bis - ( 2 - ethylhexyl ) sodium hydroxy sulosuccinate ( ahot ), which is a new surfactant, and was synthesized by our own research group. we also synthesized znfe2o4 nanoparticles using the cationic surfactant cetyltrimethylammonium bromide ( ctab )
本文分別採用通常被認為最佳的陰離子表面活性劑? ?二（ 2 -乙基己基）丁二酸酯磺酸鈉（ aot ） ，和我們課題組自己設計合成的新型陰離子表面活性劑? ?二（ 2 -乙基己基）羥基丁二酸酯磺酸鈉（ ahot ）所構成的反膠束體系為微反應器，成功制備了mnfe _ 2o _ 4納米粒子、 cofe _ 2o _ 4納米粒子和znfe _ 2o _ 4納米粒子；還以陽離子型表面活性劑? ?十六烷基三甲基溴化銨（ ctab ）構成的反膠束體系為微反應器，成功制備了znfe _ 2o _ 4納米粒子；並探討了表面活性劑的種類和結構對反膠束法制備鐵氧體納米粒子反應的影響。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。分享友人
