By deep analyzing the tested value of the concrete strength with the rebound method and combining with the inverse regression theory, a rebound strength curve ( empirical formula ) of three-parameter inverse regression is put forward 摘要基于對(duì)回彈法檢測(cè)混凝土強(qiáng)度被檢測(cè)量,結(jié)合逆回歸理論提出了一種逆回歸三參數(shù)回彈法測(cè)強(qiáng)曲線模型(經(jīng)驗(yàn)公式)。
The physical meaning of sensitive index for six worldwide representative models of crop response to water ( stewart a, jensen, minhas, blank, stewart band singh ) was analyzed based on multi-variable linear regression theory and was verified by a case study 結(jié)果表明,敏感指標(biāo)是以作物水分響應(yīng)模型所表達(dá)的統(tǒng)一回歸方程的偏回歸系數(shù),反映回歸自變量(水分)對(duì)因變量(產(chǎn)量)的作用效應(yīng),故可度量作物對(duì)水分的敏感程度。
