析方法. 本文以量纲分析在引力波物理中的应用为例子，让读者深入体会量纲分析方法的普适性. 特别地，在双黑洞并合系统
的引力波理论模板建立过程中，双黑洞总质量被当作是无关紧要的物理参数. 其原因在通常文献中只是若明若暗的被提及.
本文用量纲分析的方法展示，上述结论即使是对于超越广义相对论的一般引力理论也是成立的. 所以本文不仅清楚地论述了
上述结论在广义相对论框架下成立的理由，还为以后基于超越广义相对论的一般引力理论建立引力波理论模板提供一些
帮助.

However，the dimensional analysis is a powerful and universal analysis method in physics. Taking the application of
dimensional analysis in gravitational wave physics as an example，this paper makes readers deeply understand the
universality of the dimensional analysis method. In particular，the total mass of a binary black hole is regarded as an
uneccential physical parameter in the process of constructing the theoretical template of gravitational wave for the
binayr black holes system. The reason is rarely mentioned in the usual literature. The method of dimensional
analysis is used to show that the above conclusions are valid even for the gravitational theory beyond general
relativity. Therefore，this paper not only clearly expounds the reasons why the above conclusion holds in the
framework of general relativity，but also provides some guidelines for the establishment of the theoretical template of
gravitational wave based on the gaviational theory beyond general relativity.
