Dynamic models of competing circadian clock models.

[mRNA(X)] is mRNA for protein X, [X] protein X, and [X(nuc)] protein X in nucleus. [mRNA(Y)], [Y], and [Y(nuc)] are named in the same manner. [X:Y] is the binding complex of X and Y, [X:Y(nuc)] the complex in nucleus. m is the number of equations for each model.[mRNA(X)] 为蛋白质X的信使核糖核酸（mRNA），[X] 指代蛋白质X，[X(nuc)] 指代定位于细胞核内的蛋白质X。[mRNA(Y)]、[Y] 与 [Y(nuc)] 的命名规则与此一致。[X:Y] 为蛋白质X与Y的结合复合物，[X:Y(nuc)] 为定位于细胞核内的该结合复合物。m 代表每个模型对应的方程数目。
