The differential equation for the frictional resistance on the drillstring during tripping in high-deviated holes and horizontal holes was established. 建立了大斜度定向井及水平井起下钻过程中钻柱摩擦阻力微分方程，并推导得到钻柱摩阻的解析解。
In this report, researchers zeroed in on the length of the upper leg and found an association both with The risk of diabetes and its precursor, called insulin resistance. 而在这次研究中，研究员锁定大腿长度与罹患糖尿病和其前兆胰岛素抗阻的机率有关联。
