Thirdly , order parameters , , of smectic - a phase can be expressed as this two kinds of elementary excitations and its expression is accomplished
第三，近晶a相的序参量，，都可用上述两种元激发来表示，给出了表达式。
Three order parameters that character sa are , , . considering collective effects of reciprocity systemic , elementary excitation of condensed physics method is adopted . quantum theory is used to study sa - new microcosmic theory of sa is given
为考虑有相互作用多体系统的集体效应的影响，本文采用凝聚态物理理论中的元激发方法，用量子理论方法来研究s _ a相。
In the fifth chapter , we present the t - j model that is an important model in the system of strongly correlated electron and high temperature superconductivity at first . then , by using the ren ormalization group method , we investigate the t - j model and obtain the elementary excitation energy spectrum of it
在第五章中首先介绍了强关联电子和高tc超导的理论的一个重要模型即t - j模型，然后采用重整化群流方程方法研究t - j模型，导出出t - j模型的流方程，再由流方程求解出t - j模型的元激发能谱。
