WebBased on Equations (18)–(20), variations of μ B and C B were obtained at an interval of T = 360 s. As β B and < I BC > showed stable variations over time, μ B and C B remained constant over the specific duration of the test as shown in Figure 5A,B. Thus, μ B and C B were represented as average ± standard deviation (n = 5).
