本文详细介绍了具有扩散核的细长涡的渐近理论。面向研究生和研究人员，描述了数学模型及其数值分析。渐近分析涉及两个长度尺度和两个时间尺度。给出了涡量矩的一致性条件和时间不变性，并将其应用于数值解。作者还描述了岩心大的周向速度和轴向速度之间的一致性条件。
This is a detailed account of the asymptotic theory of slender vortices with diffusion cores. Addressed to both graduate students and researchers, it describes the mathematical model and its numerical analysis. The asymptotic analysis involves two-length and two-time scales. Consistency conditions and time invariance of moments of vorticity are given and applied to numerical solutions. The authors also describe consistency conditions between the large circumferential and axial velocity in the core.
