三体(three-bodyproblem) 相关知识点: 试题来源: 解析 天体力学中的基本力学模型。研究三个可视为质点的天体在相互之间万有引力作用下的运动规律问题。这三个天体的质量、初始位置和初始速度都是任意的。在一般三体问题中,每一个天体在其他两个天体的万有引力作用下的运动方程都可以表示成3个二阶的常微分方程,或6...

Three-body problem 是现成的术语,含义就是“三体问题”。 这是个数百年前就已存在的天体力学概念。 换句话说,不是将《三体》书名“翻译”成 The Three-Body Problem,而是在英语现有语汇里找到与原标题相关度较高的表述,加定冠词表特指,作为译版标题。 这种直接用现有术语来对应的译名,在基本贴合原意、语境相符...

《三体》英文版书名The Three-body Problem(三体问题)为什么要这样翻译呢? 其实“Three-body problem”是一个物理学名词,表示的是“三体问题”。这里就直接将其作为第一部的书名。最开始“三体”只是该系列第一部的标题,英译本也沿用了其原本的系列标题Remembrance of...
