摘要：
本文对一类单向轴对称局域脉冲给出了理论描述。文中建立了其三种表示形式之间的等价性：相对无畸变准球面波形式、Fourier-Bessel积分形式，以及波矢在给定方向上具有正投影的平面波叠加形式。
英文摘要：
A theoretical description of a class of unidirectional axisymmetric localized pulses, is given. The equivalence of their representations in the form of relatively undistorted quasi-spherical waves, in the form of Fourier-Bessel integrals and in the form of a superposition of plane waves with wave vectors having positive projections on a given direction is established.
