power-series expansion method

基本解釋

The power series expansion method is utilized to study the collective behavior in dusty plasma consisting of cold dust particles and two-temperature isothermal ions.
用冪級(jí)數(shù)展開(kāi)法研究了具有兩種溫度絕熱離子的冷塵埃等離子體體系的集體行為。
It is found that the short-time propagators obtained by using the above two methods are nearly equal, but using power series expansion technique is much easier than Schwinger method.
研究表明，這兩種方法所獲得的短時(shí)傳播子非常接近，但是后者比前者要簡(jiǎn)單得多，這給研究復(fù)雜系統(tǒng)的傳播子提供了一個(gè)簡(jiǎn)單可靠的方法。
