Imagine a particle that travels along the line in the following way: At each moment of time the particle decides randomly (and independently of the past) whether to jump to the left or to the right. Mathematicians would call this simple model a "discrete time random walk". A natural generalization of this model to continuous time would be called a "one-dimensional Levy process".

想象一个粒子以如下方式沿线移动：在每个时刻，粒子随机地(与过去无关)决定是向左还是向右跳跃。数学家会把这个简单的模型称为“离散时间随机游走”。这一模型在连续时间的自然推广将被称为“一维利维过程”。
