单词 Lorentz factor
释义

Lorentz factor

原声例句
双语版 TED-Ed 演讲精选

At 86.6% of the speed of light, the Lorentz factor is 2, meaning time will pass twice as slowly aboard the spaceship.

当速度为光速的 86.6% 时,洛伦兹因子为 2,意味着飞船上的时间慢为原来时间的一半。

双语版 TED-Ed 演讲精选

This relationship can be quantified with something called the Lorentz factor, which is defined by this equation.

这种关系可以用洛伦兹因子来量化,这是洛伦兹因子的定义公式。

中文百科

劳仑兹因子

Courbe représentative du facteur de Lorentz.

zh-hans:洛伦兹因子是一个出现在狭义相对论中的速记因子,得名于荷兰物理学家亨德里克·洛伦兹,被用于计算时间膨胀、长度收缩、相对论质量等相对论效应。

劳仑兹因子定义为:

\gamma = \frac{1}{\sqrt{1-\frac{v^2}{c^2} } } = \frac{1}{\sqrt{1- \beta^2} } = \frac{dt}{d\tau}

其中

  • v为两惯性系之间的相对速度,
  • c为真空中光速,
  • βv除以光速c的比值,
  • τ为原时,
  • t座标时间

一些作者另外定义了劳仑兹因子的倒数:

\alpha = \frac{1}{\gamma} = \sqrt{1- v^2/c^2} \ ,

可用于速度相加推导。

英语百科

Lorentz factor 劳仑兹因子

Lorentz factor γ as a function of velocity. Its initial value is 1 (when v = 0); and as velocity approaches the speed of light (v → c) γ increases without bound (γ → ∞).
α (Lorentz factor inverse) as a function of velocity - a circular arc.

The Lorentz factor or Lorentz term is the factor by which time, length, and relativistic mass change for an object while that object is moving. The expression appears in several equations in special relativity, and it arises in derivations of the Lorentz transformations. The name originates from its earlier appearance in Lorentzian electrodynamics – named after the Dutch physicist Hendrik Lorentz.
