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單得多，這給研究復(fù)雜系統(tǒng)的傳播子提供了一個(gè)簡單可靠的方法。
