The present disclosure provides a dynamic gesture identification method, a gesture interaction method and an interaction system. The interaction system includes: a dynamic vision sensor configured to trigger an event in accordance with movement of an object in a field of view relative to the dynamic vision sensor, and output an event data flow; a hand detection module configured to process the received event data flow to determine an initial position of a hand; a hand tracking module configured to determine a series of state vectors in accordance with the initial position of the hand; a gesture identification module configured to create an event cloud in accordance with event data corresponding to the obtained state vector, and process the event cloud to identify the gesture; and a command execution module configured to execute a corresponding operating command in accordance with the identified gesture.

A power saving vacuuming pump system is based on complete-bearing-sealing and dry-large-pressure-difference root vacuuming root pumps includes an input valve at an input end of a vacuum space for receiving gas mixture of saturation water vapor and non-condensed air from a condenser of a power plant; a first root vacuum pump connected to the input valve for receiving gas mixture from the input valve and then compressing the gas mixture; a second root vacuum pump connected to the first root vacuum pump for receiving gas mixture from the first root vacuum pump and then compressing the gas mixture. Inner connection walls between the vacuum chamber and the two bearing chambers are installed respective bearings which are installed to be around the driving shaft, and thus all the vacuum chamber and the two bearing chambers are tightly sealed. The vacuum chamber is completely dried so as to prevent from internal emulsion.
