gate position
1.The paper managers to explore the feasibility of automatic monitoring technology for flow discharge in Yellow River Flow Diversion Channels. This technology integrates high accurate water gate position control and high accurate water level gauge in heavy sediment and discharge calculation model with 485 computer communication to approach automatic discharge monitoring in water diversion project for optimizing regulation in water resources development.
3.Based on the introduce of the operational principle of TTL nand gate,this article gives us a vital discussion of the input load resistance characteristic of the TTL nand gate,the maximum input resistance while the circuit in the closed position and the minimum input resistance while the circuit in the open state.
