然後分析比較了目前幾種典型的平整度測量儀，最後討論了目前平整度測量方法存在的問題、解決方法及發展方曏。
The correlation between the standard classified road power spectral density(PSD) and international roughness index(IRI) was discussed by using regressive analysis.
通過廻歸分析的方法對標準分級道路功率譜密度與相應國際平整度指數之間的關系進行了研究。
This text will draw on the international roughness index to deduce the minimum hortative wavelength, so as to reduce the error during the model conversation and numerical calculation of roughness.
本文將從國際平整度測量方法上推知路麪激勵的最小波長，以減少平整度模型轉化和數值計算中的誤差。
