考查了宇宙常数λ和暗能量所反映的物理本质,指出爱因斯坦引入和放弃λ时的错误所在以及宇宙学家在真空能计算中的不合理因素;考查了“真空”和以太概念的内涵和联系,认为“真空”是以太的延续和发展,用新的以太取代“真空”这一物理学术语是必然的。

The physical origin of the cosmological constant is considered to be one of the most difficult and important problems in modern physics.

宇宙学常数的物理学起源问题被视为现代物理中最重大的疑难之一。

The cosmological constant as a measure of the energy desity of the vacuum is too small at the particle physics level, but it is comparable to the present matter density.

The Discussion about the Traditional Energy-momentum Pseudotensors under a Nonzero Cosmological Constant;

非零宇宙常数下传统能动量赝张量的讨论

Both the cosmological constant and quintessence fall into the general category of dark energy.

不管是宇宙常数还是第五元素，都属于暗能量的?畴。

In these contexts, the fields work because they are the simplest generalization of Einstein's cosmological constant.

在这样的情况下，由于纯量场是爱因斯坦宇宙常数最简化的归纳，因此它会产生作用。
