摘　　要：本文用七孔探针对于三维旋涡流场特性及三维旋涡之间的干扰流场进行了比较详细的测量。通过对于不同截面上有无旋涡干扰的两种条件下沿集中涡涡核径向的总压系数、静压系数和速度分布等特性的比较，讨论了三维旋涡之间干扰作用的机制。The flow field of three dimensional vortex and interaction between vorticeswere measured in detail by using a seven hole probe. The radial distributions of axialvelocity, total and static pressure coefficients through the vortex core were compared fortwo conditions with and without interfering vortex. The mechanism of interaction betweenvortices was discussed.
