在数值模拟一个充分搅拌的化学反应系统的时间演化过程中，最近引入的“τ跳跃”程序试图通过使用一个特殊的泊松近似跳跃的非临界反应事件序列来加速精确的随机模拟算法。本文提出了一种改进的方法，用于确定指定精度的最大跳跃大小。(C)2003年，美国物理学会。
In numerically simulating the time evolution of a well-stirred chemically reacting system, the recently introduced "tau-leaping" procedure attempts to accelerate the exact stochastic simulation algorithm by using a special Poisson approximation to leap over sequences of noncritical reaction events. Presented here is an improved procedure for determining the maximum leap size for a specified degree of accuracy. (C) 2003 American Institute of Physics.
