Finite element analysis of the thermally induced stresses in a 24 in diameter graphite electrode nipple joint 应用有限元对24吋石墨电极&接头连接引起的热应力的分析
Some bottom fixing assemblies of the temporary casing string have been designed such as air-liquid helical flow mixed nipple joint, groove casing shoe, anti-abrasive casing nipple joint and anti-backoff rotation device. 设计了气液旋流混合短节、防挂坡口套管鞋、耐磨套管短节、防倒扣旋转装置等临时套管柱下部固定结构。
The importance of mammography should be emphasized on in the detection of breast cancer which can not be touched. Ultrasonography, mammography and bloody nipple discharge testing should be joint in complementary diagnosis. 对检测不可触及的乳腺癌,应强调钼靶的重要性,超声、钼靶和乳头血性溢液的检测应互补联合诊断。
