Abstract

It has been shown previously (P. R. Bunker and Per Jensen, J. Quant. Spectrosc. Radiat. Transf., 243 (2020) 106835) that if we choose angles to have dimension, we have to distinguish between the Planck constant $h$ , having the dimension of $action {angle}^{- 1}$ , and the Planck constant of action $h_{A}$ , having the dimension of $action$ . In the present paper, we show that a further implication that results from choosing angles to have dimension is that the Kibble balance equation relating the mass weighed to the Planck constant has to involve both of the distinct fundamental constants $h$ and $h_{A}$ . We derive that new equation here and show how it compares to the equation that is obtained if one chooses angles to be dimensionless as required in SI.

普朗克作用常数与Kibble平衡

这在以前已经被证明(P. R. Bunker和Per Jensen, J. Quant. Spectrosc)。Radiat。Transf.， 243(2020) 106835)，如果我们选择角度有维度，我们必须区分普朗克常数h，具有作用角- 1的维度，和普朗克常数hA，具有作用的维度。在这篇论文中，我们证明了选择具有维度的角度所产生的一个进一步的含义是，将质量称重到普朗克常数的基布尔平衡方程必须包含两个不同的基本常数h和hA。我们在这里推导了这个新方程，并展示了它与在SI中选择无量纲角度时得到的方程的比较。
