论文摘要
在模型构建研究中，重要的是要检查由重力场方程确定的相应能量弹药张量的能量条件，以便单独挑选出物理合理的模型。在此过程中，人们经常遇到一种情况，即能量弹药张量在给定的时空中具有正顺序的框架中具有一个非对角性的“时空”组件。在这种情况下，我们得出了能量弹药张量的有用标准和标准能量条件。作为演示，我们将这些标准应用于四个不同的系统。
In model building studies, it is important to check the energy conditions for the corresponding energy-momentum tensor determined by the gravitational field equations in order to single out physically reasonable models. In this process, one often encounters a situation where the energy-momentum tensor has one off-diagonal "space-time" component in the frame with an orthonormal basis in a given spacetime. We derive useful criteria of energy-momentum tensors for their Hawking-Ellis types and the standard energy conditions in such situations. As demonstrations, we apply those criteria to four different systems.
