The character of this paper is that the linear recursive analysis is adopted on the prediction of demand and supply in xi ' an dwelling house market on which the strategy study is based on 本文的特點(diǎn)在于:采用一元線性回歸方法,對(duì)未來西安市住宅市場(chǎng)的供求情況進(jìn)行預(yù)測(cè),對(duì)定量分析西安市住宅建設(shè)發(fā)展問題進(jìn)行了初步嘗試。
The relation between the diameter and wall thickness of transparent pipe is drawn from lots of experiment data . with recursive analysis , the error of wall thickness measurement is compensated 本文在理論分析的基礎(chǔ)上,通過大量的實(shí)驗(yàn),找到了玻管外徑和壁厚之間的關(guān)系,并用回歸分析法對(duì)實(shí)驗(yàn)結(jié)果進(jìn)行處理,從而對(duì)壁厚的測(cè)量誤差進(jìn)行補(bǔ)償,使測(cè)量系統(tǒng)的精度滿足使用要求。
Based on the multi - level recursive analysis and the grey system theory , the forecast models on the safety assessment of the levee engineering are founded . and with the modern computer technique of software and hardware , the precautionary mode of the safety assessment of the levee engineering is designed 5 、利用回歸分析方法和灰色系統(tǒng)理論建立了堤防工程安全預(yù)報(bào)模型,初步設(shè)計(jì)了堤防工程安全預(yù)警系統(tǒng)模式,并開發(fā)研制了堤防安全監(jiān)測(cè)實(shí)時(shí)評(píng)價(jià)軟件。
