沉积速率测量可视为运用梳状滤波器对沉积过程的谱分离过程。在含波动成分的海岸沉积过程中,沉积速率因抽样时间和抽样间隔而异,往往表现出“谱”的特征。据此,文章讨论了地形学方法和地质学方法在提取和分析沉积速率谱方面的潜力和局限。
Deposition rate measurement can be regarded as the spectral separation process using the comb filter for the deposition process. During the coastal sedimentation with fluctuating components, the deposition rate often differs from the “spectrum” due to sampling time and sampling interval. Accordingly, the article discusses the potential and limitations of topographic methods and geology methods in the extraction and analysis of deposition rate spectra.
