如果纯量场变化缓慢,它就会有固定的大小,而且没有方向性,就像一个常数一样;
If a scalar field changes slowly, it resembles a constant, both in its fixed magnitude and in its lack of directionality;
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。
In these contexts, the fields work because they are the simplest generalization of Einstein's cosmological constant.
