Key techniques of on-line concentrated sampling are analyzed and relations of accumulator prechargepressure and pressure-retaining results are studied.
分析了实现在线浓缩取样的关键技术，研究了蓄能器预充压力和采样筒保压效果的关系。

Depending on the fluid volume and prechargepressure of the accumulator, a limited amount of hydraulic energy is then available independent of any other power source.
根据储能器的流体体积和预充气压力，可获得某限定数量的液压能量而不依赖任何其它动力源。
