Second, the electric submersible pump connected to the pipe thread pretightening force enough (or not pre-torque).

第二，电潜泵各管螺纹联接的预紧力不够（或预紧扭矩不够）。

By applying different pre-pressure, the speed, torque and temperature of the ultrasonic motor in low and high vacuum have been tested and compared with the normal condition.

施加不同的预压力在低、高真空环境下对超声电机的转速、转矩及温升进行测量并与常态下相比较。

We are pre tty clear, however, on what the Hemi V-8 offers-power and torque, and lots of both-and it tu gs the GC around with a rowdy rumble and a shrug of its shoulders.

我们很清楚，但是，关于什么赫米的V - 8提供功率和扭矩，并同时和它周围的GC拖轮用粗暴的地段隆隆作响，其肩膀耸耸肩。
