過去有關特有現象的研究主要限於定性的分析，可比性和精確性較差.該文嘗試引入特有現象的定量化指標，以推動特有現象的分析研究從定性水平向定量水平邁進.所引入的4種定量化指標分別是：特有水平、特有系數、特有度以及特有綜合指數.對每種量化指標都給出了數學表達式，說明了其區系學意義，例證和界定了這些指標在植物區系分析中的應用，結果表明，它們有良好的適用性.這些指標充分地包含了植物系統學和植物區系學的信息.結合定性分析，這些指標的應用將增強植物區系研究的可比性，使植物區系特有現象的分析達到更精確的水平These concepts were firmly entrenched in the mathematical formulation of classical mechanics.
