| 摘 要： | 本文提出了一种测量石油含水率(O～100％)的方法,即微波驻波法。对微波而言,油和水的波阻抗相差很大,其反射系数也相差很大。因此,当一束微波从同轴式天线探头发射到被测石油中,将按含水率的不同产生相应强度的反射。反射波经同轴式天线探头接收后与入射波迭加成驻波,即同轴线工作于驻波状态。利用固定于线上某一位置的检波器把它转换为电量,测量其值,便可确定探头所在处介质(石油)的含水率。

| Abstract: | This paper suggests a method for measuring the percentage water content in crude oil (1~100%), namely, microwave standing wave method. Since water and oil differ greatly in wave impedances, their reflection coefficients for microwave are different. Therefore, when a beam of microwave is transmitted into crude oil to be measured through a coaxial antenna sensor, the reflected wave occurs, the intensity of which is in accordance with the percentage water content in crude oil. Superpositions of the reflected wave received by coaxial antenna sensor and the incident wave become a standing wave, that is, the coaxial line works in a state of standing wave. The percentage water content in dielectric (e.g. crud oil) at the place where the sensor is placed can be determined by measuring the electrical quantity transformed by the detector fixed on the line. |
