摘　　要：利用变分法得到了任意光脉冲传输的一般特性及高斯光脉冲压缩（或扩展）的必要条件。这说明在一定初始条件下时空非对称的光脉冲也可形成“光子弹”，在某些区域内，通过时空耦合作用。By using variational method, some conservative laws for the propagation of light pulse in bulk media are studied and the neccessary conditions for compression or broadening of a light pulse are obtained. It is possible to obtain light bullet from a light pulse without temporal spatial symmetry. By the impacts of temporal spatial coupling property spatial convergence of an optical beam may lead to the compression of pulse width.
