It is well known that the linear-noise approximation (LNA) agrees with the chemical master equation, up to second-order moments, for chemical systems composed of zero and first-order reactions. Here we show that this is also a property of the LNA for a subset of chemical systems with second-order reactions. This agreement is independent of the number of interacting molecules.
众所周知,对于由零阶和一阶反应组成的化学系统,线性噪声近似(LNA)在二阶矩以内与化学主方程一致。在此我们表明,对于具有二阶反应的化学系统的一个子集,这也是LNA的一个特性。这种一致性与相互作用分子的数量无关。
