论文摘要
在建模相对论热力学时,我们经常将颗粒数视为保守数量。该数字保护定律来自于以下要求,即从流体 - 遗物3空间中的下拉构造与四维拉格朗日变化的独立组件的数量相同,这支持了这一假设。另一方面,安德森(Andersson)和comer [1]认为,它们的变异模型与非变化的粒子创造率兼容。我们支持结果,并证明考虑到创建率的效果的适当变异公式使我们能够在无需任何其他要求的情况下对待非呈现创建率。
In modeling relativistic thermodynamics, we frequently regard the particle number as a conserved quantity. The number conservation law, which comes from the requirement that the pull-back construction from fluid-matter 3-space has the same degrees of freedom as the number of independent components of the four-dimensional Lagrangian variations, supports the assumption. On the other hand, Andersson and Comer[1] argue that their variational model is compatible with non-vanishing particle creation rates. We support the result and prove that a proper variational formula considering the effect of the creation rate enables us to treat the non-vanishing creation rate without any additional requirement.
