摘要翻译：
本文采用超临界级数展开式和有限尺度精确解两种不同的方法研究了一维带扩散接触过程的临界性质。我们特别强调了多点及其交叉指数，它表征了DP和平均场临界性质之间的通道。这种交叉发生在无限扩散速率的极限，我们的结果表明$\phi=4$是交叉指数的较好估计，与计算模拟一致。

英文摘要：
  In this work we study the one-dimensional contact process with diffusion using two different approaches to research the critical properties of this model: the supercritical series expansions and finite-size exact solutions. With special emphasis we look to the multicritical point and its crossover exponent that characterizes the passage between DP and mean-field critical properties. This crossover occurs in the limit of infinite diffusion rate and our results pointed $\phi=4$ as the better estimate for the crossover exponent in agreement with computational simulations.
