| 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=ac]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′ |
| 关 键 词： | 非离子型X线造影剂 粘度 线性关系 |

| 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=ac] 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′ . |
| Keywords: | non ionic X ray contrast agent viscosity concentration linear relationship |
