| 摘 要： | 在实测新疆原油小于３５０℃馏分油常压和大于３５０℃重油减压不同条件下的汽液平衡数据基础上，探索将正构烷烃模型分子法与ＵＮＩＦＡＣ基团贡献法相结合，按三种相平衡常数模型，预测新疆原油直馏油汽液平衡．通过对泡、露点温度与平衡闪蒸温度的考察，证实了该法的可行性，计算准确性能满足工程实用要求

| Abstract: | The high temperature rheological behaviour of some rock bits lubrication grease in China was studied by using the HAAKE RV3 rheometer. The relative rheological equations are presented. The experimental results reveal that the soup type rock bits greases, such as 7411, seals and J783 behave the properties of the typical Bingham fluid. The non soup type grease ZT 9 is of the properties of the Herschel Bulkley fluid. |
