The mixing chamber of headbox plays an important role in homogenizing pulp flow and stabilizing pressure fluctuation of pulp. The length of mixing chamber is an important parameter.
混合室在流浆箱中起着均匀浆流、稳定压力的重要作用，而混合室的长度是混合室设计中的重要参数。
The critical factor causing the arc length fluctuation to affect the input heat power to the anode proves to be the phenomenon of the current dispersion in plasma arc itself.
文中指出，弧长波动影响阳极输入热功率的重要因素是等离子电弧本身存在着电流分散现象。
Based on analytical method, the paper shows that raising the length of a riser can elevate the water-hammer pressure and reduce the fluctuation of water level effectively in surge tank.
通过理论和解析方法讨论连接管较长时，其内水体惯性对调压井水锤压力和水位波动的影响。实例分析表明：连接管长度增加可使调压井水锤压力升高，水位波动幅值减小。
