“accumulator”的概念、定义、翻译、参考文献-科学参考

accumulator

Physics

A type of voltaic cell or battery that can be recharged by passing a current through it from an external d.c. supply. The charging current, which is passed in the opposite direction to that in which the cell supplies current, reverses the chemical reactions in the cell. The common types are the lead–acid accumulator and the nickel–iron accumulator and nickel–cadmium accumulator. See also sodium–sulphur cell.

Chemical Engineering

A device used to smooth the rate of flow from a reciprocating pump and prevent the destructive effects of water hammer from occurring. It consists of a vessel located on the pipe close to the pump with a non-return valve preventing return flow back to the pump. The vessel contains a gas or a bladder bag although some use springs. As the pump discharges, some of the fluid enters the accumulator compressing the gas or spring. At the point of valve closure, the gas or spring expands allowing the accumulated volume to discharge through the pipe.

Computer

A register that is implicitly specified by one-address format instructions and is used to contain the results of an operation performed by the ALU. It can normally be one of the inputs to the ALU, thus the results of a number of successive operations may be built up—hence the name. In addition to holding results, the accumulator commonly has the ability to perform the various shift and circular shift instructions. It may be part of the processor status word.
