The maximum value of the calculated mass fractionnormalized conductivity of ME-AR was found to be the mark of the occurrence of asphaltene precipitation.
结果表明,渣油质量分数电导率的最大值可以看作是用正庚烷稀释时沥青质聚沉的发生点。

The electrical conductivity of Middle East Atmospheric Residue (ME-AR) diluted by n-heptane was continuously measured, and the mass fractionnormalized conductivity of ME-AR was calculated.
测定了中东常压渣油加入正庚烷后的电导率,并计算得到了不同正庚烷加入量时的质量分数电导率值。
