受阻扭轉 的英文怎麼說
中文拼音 [shòuzǔniǔzhuǎn]
受阻扭轉
英文
hindered torsion-
Such ischemia most often results from hypotension ( shock ) from cardiac failure, from marked blood loss, or from loss of blood supply from mechanical obstruction ( as with the bowel incarcerated in a hernia or with volvulus or intussusception )
局部缺血常見于由心衰、大量失血、血管受阻（見于腸疝、腸扭轉或腸套疊）所導致的低血壓（休克） 。On the contrary, because of the effect of positive damping provided by the inverter, the unit near a inveter will have no subsynchronous oscillation risk. based on the same method described above, a damping study is carried out for a hybrid ac / dc system, which include a hvdc link and an ac transmission line in parallel
研究表明，系統整流站附近的同步發電機組要承受電氣負阻尼作用，因此有可能引起機組低頻扭轉振蕩模式失穩；而hvdc的逆變站向其臨近同步發電機組提供正阻尼，因而機組不存在次同步振蕩危險。By establishing force equilibrium equations, a mechanical model for calculating the friction on the string is set up, and the analytical formulas for calculating the hook load and wellhead torque when the string is tripped in
通過建立管柱受力平衡方程，推導出水平井管柱入井時摩阻計算的力學模型，分析計算了在穩定和旋轉方式下管柱入井時的大鉤載荷和井口扭矩等重要技術參數的解析公式。The result of simulation of model 8 ? 1 / 2 ? xhp2s bit shows that, the torque on the bit changes randomly, and the degree of the change increases with the increase of the weight on bit ; the change of the torque on the upper part of the drillstring is not so large as that on the string ' s lower part, and the rotary speed of the bit changes smoothly overall
對8英寸xhp2s鉆頭做了模擬，結果表明，鉆頭處受巖石的阻力扭矩是隨機變化的，並有負扭矩出現，扭矩的變化幅值隨靜鉆壓的增加而增加；鉆柱頂部轉盤施加的扭矩變化不如底部劇烈；鉆頭的轉速在局部有較小的波動，其總體變化較為平緩。分享友人
