塵埃等離子體穩(wěn)態(tài)帶電顆粒位形分布研究塵埃等離子體穩(wěn)態(tài)帶電顆粒位形分布研究

摘要：本文主要研究塵埃等離子體穩(wěn)態(tài)帶電顆粒的位形分布情況。通過(guò)對(duì)等離子體物理學(xué)、復(fù)雜網(wǎng)絡(luò)理論以及統(tǒng)計(jì)物理學(xué)的探究，研究了帶電顆粒在塵埃等離子體中的行為。進(jìn)一步探究了帶電顆粒與等離子體中的離子、電子、塵埃等其他物質(zhì)的相互作用關(guān)系，建立了塵埃等離子體穩(wěn)態(tài)帶電顆粒的模型。利用電子探針、掃描電鏡等實(shí)驗(yàn)手段進(jìn)行實(shí)際樣本的采集和分析，得到了大量的實(shí)驗(yàn)數(shù)據(jù)。對(duì)實(shí)驗(yàn)數(shù)據(jù)和理論模型進(jìn)行了對(duì)比分析，發(fā)現(xiàn)帶電顆粒的位形分布狀況是分形分布的。分析了產(chǎn)生這種分形分布的原因，同時(shí)發(fā)現(xiàn)分形分布的維度受到等離子體參數(shù)、帶電顆粒密度等因素的影響。最后，通過(guò)計(jì)算機(jī)模擬得到了帶電顆粒在塵埃等離子體中的行為。
