不幸的术语
Unfortunate Terminology
摘要：
“负平方静止质量”这个短语有时可以在关于中微子的论文中找到，也经常出现在快子文献中。因此，有些作者说“快子的静止质量是虚构的”。此外，“光子静止质量为零”的说法几乎是常见的。然而，从相对论的角度来看，对于Luxons和Tachyons来说，静止状态无法合理地定义，因此，今天谈论这些物体的静止质量是没有意义的。它示出在这里，短语“负平方质量”，“虚质量”，和“光子的零质量”的结果，从应用缓子动力学相对论关系，以确定luxons和快子的属性;和这个错误的程序结果从一个不幸的解释运动学相对论关系。它还表明，使用适当的相对论关系，即luxonic或tachyonic的，给出了一个积极的量的平方质量尺寸。这样我们就得到了一个具有质量维数的非零实量（称为类质量量），它对光子是正的，对其他的luxons和tachyons可能（凭直觉-应该）是正的。
英文摘要：
The phrase "negative squared rest mass" can sometimes be found in papers on neutrinos and frequently occurs in the tachyonic literature. Consequently, some authors say that "the rest mass of tachyons is imaginary". Besides, the statement "photons have zero rest mass" is almost common. In terms of relativity, however, the state of rest cannot be reasonably defined for luxons and tachyons, and, therefore, today it does not make sense to speak of rest mass of such objects. It is shown here that the phrases "negative squared mass", "imaginary mass", and "photon's zero mass" result from applying bradyonic dynamical relativistic relations to determine properties of luxons and tachyons; and that this erroneous procedure results from an unfortunate interpretation of kinematical relativistic relations. It is also shown that the use of proper relativistic relations, i.e. luxonic or tachyonic ones, gives a positive quantity having the squared mass dimension. Thus we obtain a nonzero real quantity having the mass dimension (called masslike quantity), which is positive for the photon and may (by intuition - should) be positive for other luxons and for tachyons.
