We introduce a new method for transforming chemical systems into desired logical operators (e.g. NAND gates) or similar signal-manipulation components. The method is based upon open-loop dynamic regulation, where external conditions such as feed-rate, lighting conditions, etc., are modulated according to a prescribed temporal sequence that is independent of the input to the network. The method is first introduced using a simple didactic model. We then show its application in transforming a well-stirred cubic autocatalytic reaction (often referred to as the Selkov-Gray-Scott model) into a logical NAND gate. We also comment on the applicability of the method to biological and other systems.
我们介绍了一种将化学系统转换为所需逻辑运算符（例如 NAND 门）或类似信号处理组件的新方法。该方法基于开环动态调节，其中外部条件（例如进料速率、照明条件等）根据与网络输入无关的规定时间序列进行调制。该方法首先使用简单的教学模型进行介绍。然后，我们展示了它在将搅拌良好的立方自催化反应（通常称为 Selkov-Gray-Scott 模型）转换为逻辑 NAND 门中的应用。我们还评论了该方法在生物和其他系统中的适用性。
