1.前言本文所述气流回路的设计目标具有双重意义。首先,流路必须将气源的压力(P_S)减小到气流需要的某个理想值,其次,该流路必须控制实验位置的最大压力,这是许多传感器可应用的必要条件。限压作用减少了因压力偶然超出设计极限而造成流体设备损坏的风险。在许多领域可看到这方面应用的例子。例如在呼 1. Introduction The design goals of the airflow circuit described in this article have a dual meaning. First, the flow path must reduce the gas pressure (P_S) to some desired value for the gas flow. Second, the flow path must control the maximum pressure at the experimental site, which is a requirement for many sensors. The pressure limiting effect reduces the risk of damage to the fluidic device due to accidental pressure surges beyond the design limits. In many areas can see examples of this application. For example, call
