详细分析了一种用于产生自由射流和分子束的常用脉冲阀的特性。特别注意的是提供一个准定常流在一定的时间间隔内的脉冲持续时间内的气体脉冲的形成，并估计的缩放参数（有效直径）的描述的流场。通过对Ne、N2和CH4的分子束进行飞行时间测量，以及对N2和CH4的自由射流进行受激拉曼光谱，来检查该有效直径的适当性。
The characteristics of a commonly used pulsed valve for the production of free jets and molecular beams are analyzed in detail. Special attention is paid to the formation of gas pulses providing a quasisteady flow during a certain time interval within the pulse duration, and to the estimation of a scaling parameter (effective diameter) for the description of the flow field. The adequacy of this effective diameter is checked by performing time‐of‐flight measurements on molecular beams of Ne, N2, and CH4, and stimulated Raman spectra on free jets of N2 and CH4.
