Traditional spectrum quantitative analysis needs to utilize the standard sample experiment to get the calibration curve before the quantitative result is done.
传统的光谱定量分析，在定量结果得出之前需要利用国际标准样品实验得到定标曲线。
The power spectrum of wind speed time series sample is coincident with the aim power spectrum curve.
得到的风速时程样本的功率谱密度与目标曲线吻合很好。
