一、引 言 由于化工设备的扩大和复杂化,为了避免意外的事故,脉动预测已成为管路系统设计中的主要问题。到目前为止,缓冲器的尺寸只用通用的计算公式来概略地确定。这是因为脉动预测这个问题是很复杂的,此外,它还包含着一些难以确定的因素（即孔板插入处理、波沿管路的衰减系数等）。 I. INTRODUCTION Due to the expansion and complication of chemical equipment, pulsation prediction has become a major issue in the design of piping systems in order to avoid accidental accidents. So far, the size of the bumper has only been approximated by a general calculation. This is because the problem of pulsation prediction is complicated. In addition, it contains some difficult factors (such as orifice insertion processing, wave attenuation along the pipeline, etc.).
