From the front to the rear of the axial flow compressor，the height of the rotating blades:
举一反三
- The fan_____the engine provides a flow of air. A: at the front of B: at the rear of C: at the bottom of D: at the top of
- When the spindle has axial movement, when turning workpiece (). A: Cylindricity error will be produced on the rotating surface B: Drum shape error will be produced on the rotating surface C: It will affect the axial dimension accuracy and end face shape D: Roundness error will be produced on the rotating surface
- Because of the spindle has axial movement, when turning workpiece (). A: roundness error will be produced on the rotating surface B: cylindricity error will be produced on the rotating surface C: it will affect the axial dimension accuracy and end face shape D: drum shape error will be produced on the rotating surface
- 在一个链队列中，若队首指针为front，队尾指针为rear，则判断该队列只有一个结点的条件( )。 A: front==rear && front !=null B: front==rear C: front==rear && rear !=null D: front!=rear
- When the number of blades is limited, the flow is strictly guided by blade surface.
