摘要
对黄胞胶在铬离子存在下的成冻反应进行了试验。描述了反应的动力学过程，考察了温度、铬离子浓度以及剪切速率对反应速度的影响。讨论了黄胞胶／铬作为调剖剂的应用。
he gelation of xanthan gum in the presence of chromic ion was tested successfully .The authors describe the dynamic process of the gelation reaction,and analyse the influences ofthe temperature,chromic ion concentration and shear rate upon the reaction rate. They alsodiscuss the use of xanthan gumlchromium as profile correction agent.
