【摘要】 对常用的几种非离子型 X线造影剂的粘度进行了研究。结果表明 ,造影剂溶液的粘度 η(m Pa· s)随造影剂浓度 c(g I/ m L)的增加急剧增加 ,粘度与造影剂浓度的四次方呈线性关系 :η=a[c]4 +b;粘度随温度的上升而急剧下降 ;浓度越高 ,温度对粘度的影响越大 :η′=a′t+b′更多还原

【Abstract】 The viscosity of several non ionic X ray contrast agents were studied. The results shows that the viscosity η (mPa·s) of the contrast agent solution increased rapidly with the increase of the concentration c( gI/mL) of contrast agent solution. The relationship between η and [ c] 4 is linear: η=a[c] 4+b . Moreover, the viscosity (η′ ) decreased as the temperature is increased.There is a negative linear relatianship between viscosity and temperature η′=a′t+b′ .更多还原
