摘　　要：对野外管线输送的3号喷气燃料电导率与温度的关系进行了研究。通过实验验证证明:(1)同种3号喷气燃料测试温度与电导率的自然导数值有线性关系。(2)电导率取自然对数与温度的线性关系中的斜率和截距随不同3号喷气燃料而不同,其中截距变化较小。这种关系反映在温度相对低的情况下,温度的变化对电导率影响较小,反之则影响较大。(3)加有抗静电添加剂的3号喷气燃料在不同温度下测定的电导率符合文献中喷气燃料电导率与温度变化的典型范围,且只要随机测定2个温度点的电导率就可以计算出斜率和截距,由此建立线性关系,对野外任意温度下测定的电导率可以推导出20℃温度下电导率的数值。(4)了解3号喷气燃料电导率与温度的关系,可将野外管线输送的喷气燃料测定的电导率立即转化为标准温度下(20℃)的电导率数值,并据此及时判定该燃料电导率是否合格。(5)根据电导率与温度的关系公式,可以开发在线电导率检测仪器,以便快速测定喷气燃料电导率数值。The relationship between conductivity and temperature of No.3 jet fuel transported by field pipeline was studied.The experimental results are obtained:(1)There is a linear relationship for the same No.3 jet fuel between the test temperature and the natural logarithm of conductivity.(2)The slope(b)and intercept(a)in the linear relationship between natural logarithm and temperature are different with different No.3 jet fuels,and the intercept changes slightly.This relationship reflects that when the temperature is relatively low,the change of temperature has little effect on the conductivity,and vice versa.(3)The measured conductivity of No.3 jet fuel with antistatic additive at different temperatures conforms to the typical range of jet fuel conductivity and temperature change in literature,and the slope and intercept can be calculated as long as the conductivity at two temperature points are measured randomly,so as to establish a linear relationship.Based on the conductivity measured at any temperature in the field,the conductivity value at temperature of 20℃can be deduced.(4)Understanding the relationship between conductivity and temperature of No.3 jet fuel can immediately convert the measured conductivity of jet fuel transported by field pipeline into the conductivity value at standard temperature(20℃),which can be used to judge whether the conductivity of the fuel is qualified in time.(5)According to the relationship between conductivity and temperature,an on-line conductivity detection instrument can be developed to quickly determine the conductivity of jet fuel.
