I. Introduction
Pattern formation can be induced by diffusions which has been proposed by Turing in 1952s [1]. Therefore, these kinds of patterns can also be called Turing patterns. He believed that patterns could emerge in reaction-diffusion systems involving different substances with significant differences in diffusion rates, driven by the spontaneous breaking of symmetry. Many scholars studied pattern formation by reaction-diffusion systems. Many chemical reactions exhibit diffusion phenomena, and the diffusion processes of various chemical substances can be described by reaction-diffusion systems. A series of chemical reaction-diffusion systems have been developed, such as the Schnakenberg model [2], the Gray-Scott model [3], and the Gierer-Meinhardt model [4].
