We exploit the particulars of diffusive wave front interactions in certain types of two-reactant reaction-diffusion medium to construct a laboratory prototype of an XOR gate. In the design, the values of the logic variables are represented by the presence or absence of a precipitate, "wires" are constructed of a substrate loaded gel, and the computation is based on diffusive wave dynamics. We also discuss implementation of AND gate and study a three-valued composition, derived from the gate dynamic, and discuss possible logics that could be derived from this composition.
我们利用某些类型的双反应物反应扩散介质中扩散波前相互作用的细节来构建一个异或门的实验室原型。在该设计中，逻辑变量的值由沉淀物的有无表示，“导线”由负载凝胶的基质构成，并且计算基于扩散波动力学。我们还讨论了与门的实现，并研究了从门动态推导出来的三值组合，以及讨论了可以从该组合推导出来的可能逻辑。
