Sure. We could try multiple regressions with varying physical and experimental constants.

可以啊。我们试试用不同的物理常数与实验常数进行多元回归分析。

Another question concerns the physical constants on which the different forces rely, such as the fine-structure constant, which determines the strength of the electromagnetic force.

另一个问题涉及不同力所依赖的物理常数，例如决定电磁力强度的精细结构常数。
