μW/mm³/g² 形式歸一化。這與你想使用輸入加速度強度歸一化功率的思路一致。對您的論文或報告,建議如下定位:
P(f),也就是 P(t)=Vrms(t)^2/R,再利用已知的 f(t) 映射到頻率。功率譜密度基礎的頻譜功率分佈 或 輸入歸一化頻譜功率指標(input-normalized spectral power metric)可使用的英文表述:
Frequency-sweep tests were used to characterize the broadband harvesting performance, while PSD-based spectral power analysis was used as a complementary frequency-domain energy metric. [1][3][6][7] Since the sweep excitation was treated as a nonstationary test condition in this analysis, the PSD-based result was interpreted as a spectral power distribution rather than a strict steady-state power-frequency response.
