WebFormula 1-15: pV throughput As can be seen from the right-hand side of the equation, a constant mass flow is displaced at constant temperature T. This is also referred to as pV flow or gas throughput. Throughput is the gas flow rate transported by a vacuum pump. qpV = S ⋅ p = dV dt ⋅ p q p V = S ⋅ p = d V d t ⋅ p WebAug 12, 2024 · 1托=1/760大气压=1毫米汞柱 1托=133.322帕 1帕=7.5×10-3托 漏率:密闭真空空间在外界标准大气压和单位时间内, 物质泄漏的速率。 漏率常用单位:Pa.m3/sec、mbar.l/sec、atm.cc/s 10 Pa.m3/sec=1 mbar.l/sec=1 atm.cc/s 分子泵:通过高速旋转的叶轮,当气体分子与涡轮叶片相碰撞时就被驱向出气口再由前级泵抽除。 3.3测试仪器 氦质谱 …
