提出了一种基于瑞利散射的直接测量高压气体射流产生的团簇径迹的光学方法。氩气和甲烷团簇的轨迹由高速相机获得。结果表明，这些径迹的团簇尺寸范围为：Ar为7 E + 03~ 1 E + 07，甲烷为2 E + 06~ 4 E + 08.氩离子的径迹大多是连续的，其强度逐渐变化，而甲烷的径迹大多是离散的，其强度沿飞行路径沿着周期性变化，这可能表明甲烷团簇更不稳定，更容易破碎。还发现了轴向速度小于2.5m/s的特殊甲烷团簇，该方法对大团簇非常敏感，在团簇物理中有广阔的应用前景。
We propose an optical method based on Rayleigh scattering for the direct measurement of cluster tracks produced by a high-pressure gas jet. The tracks of the argon and methane clusters are acquired by a high-speed camera. It is found that the cluster sizes of these tracks are within the range of 7E + 03~1E + 07 for argon and 2E + 06~4E + 08 for methane. Most argon tracks are continuous and their intensity changes gradually, while the majority of the methane tracks are separated into discrete fractions and their intensity alters periodically along the flight path, which may indicate the methane clusters are more unstable and easily to break up. Special methane clusters which may fly at an axial velocity of less than 2.5m/s are also found. This method is very sensitive to large gas cluster and has broad application prospects in cluster physics.
