Computer simulation of fundamental second - order system ' s response to unit step function based on matlab6 5的歸一化二階系統(tǒng)單位階躍響應(yīng)的模擬演示
According to the crown growth characteristics in industrial eucalyptus stand of short rotation , the unit step function model was put forward for the process with changing point of short rotation eucalyptus clones u6 based on the survey practical stands 摘要針對(duì)短輪伐期桉樹(shù)人工林林分冠幅生長(zhǎng)的特點(diǎn),在現(xiàn)實(shí)林分調(diào)查的基礎(chǔ)上,模擬提出了適合有變點(diǎn)的短輪伐期桉樹(shù)u6無(wú)性系林分冠幅生長(zhǎng)階躍函數(shù)模型。
The analyzable conclusions of the regression model between crown diameter and age show that the utility of unit step function model in the crown growth process with the changing point is better than the usual regression methods , and the unit step function model can solve discontinuance on the changing point 對(duì)樹(shù)冠與林齡的回歸分析結(jié)果表明:階躍函數(shù)模型在具有變點(diǎn)的桉樹(shù)林分樹(shù)冠生長(zhǎng)過(guò)程中的應(yīng)用效果優(yōu)于一般回歸擬合模型,可較好地解決分段擬合模型在變點(diǎn)上的不連續(xù)問(wèn)題。
