In this dissertation, a key point of the study is to build up a mathematical model of the character impedance the swr sensor. the structure of four equal - length probes can be viewed as a special form of coaxial hansnussion line. combining the character impedance of coaxial and the para1lel transmission line, the character impedance model of probe with eqtlaling length was built up by utilizing mathemaical theory of approach
本文將四針等長式結構的土壤水分探頭看成是同軸傳輸線的特殊形式，從標準傳輸線特徵阻抗入手，結合平行傳輸線，運用數學上常用的夾逼定理，得出了四針等長結構的土壤水分探頭特徵阻抗數學模型，由此提出swr型土壤水分四針不等長探頭的特徵阻抗數學模型。
