【摘要】：利用LCR數(shù)字電橋測(cè)量?jī)x及自制加持平行電極板,測(cè)量10、100、1 000 k Hz條件下土壤的相對(duì)介電常數(shù)與3種主要影響因素之間的變化規(guī)律。采用多元線性回歸分析原理及模型,結(jié)合土壤相對(duì)介電常數(shù)的實(shí)測(cè)數(shù)據(jù),運(yùn)用SPSS軟件對(duì)3種主要影響因素進(jìn)行多元回歸分析,得到了各因素與相對(duì)介電常數(shù)之間的相關(guān)關(guān)系及權(quán)重。結(jié)果表明,含水率、容重和溫度與土壤相對(duì)介電常數(shù)顯著相關(guān)(P0.05),其中含水率和溫度與土壤相對(duì)介電常數(shù)極顯著相關(guān)(P0.01);利用多元線性回歸建立不同測(cè)試頻率下土壤相對(duì)介電常數(shù)與含水率、容重、溫度3因素的回歸方程,且權(quán)重的大小順序始終為容重溫度含水率。
[Abstract]:The use of LCR digital measuring instrument bridge and self-made blessing parallel plate electrodes, the variation between the factors of relative dielectric constant of the soil and the 3 main influencing measurement of 10100,1 000 K Hz. Under the condition of regression analysis and principle of using multiple linear model, combined with soil relative dielectric constant of the measured data, using the SPSS software regression analysis on the factors the 3 main effects, the relationship between the various factors and the relative dielectric constant and weight. The results showed that the moisture content, temperature and bulk density were significantly correlated with the soil relative dielectric constant (P0.05), in which the temperature and soil moisture content and relative dielectric constant were significantly correlated (P0.01); different regression the test frequency of soil permittivity and moisture content, using the multiple linear regression equation of density, temperature of the 3 factors, and the weights of the order is always the temperature moisture content. Soil bulk density
