This paper deals with the global boundedness of the two-species chemotaxis system u t =△u -·(uχ1 (w)△w)+μ1 u(1 -u), x∈Ω,t >0, vt =△v -·(vχ2 (w)△w)+μ2 v(1 -v), x∈Ω,t >0, w t =△w +u -w -vw x∈Ω,t >0{, under homogeneous Neumann boundary condition in a smoothly bounded domain ΩRn (n≥1 ),with nonnegative intial data u0 ,v0∈C0 (Ω)and w0∈W1 ,∞ (Ω).槇χi ,αi ,μ1 has a chemotactic sensitivity function and satisfies χi (w)≤槇χi (1 +αi w)δi ,where the parameters槇χi ,αi ,μ1 and μ2 are positive δi >1 .Under the condition that 槇χ1 ,槇χ2 and μ1 +μ2 satisfy some specified conditions,the corresponding initial-boundary value problem possesses a unique global classi-cal solution and is uniformly bounded.%研究了一个关于两个物种趋化模型的初边值问题u t =△u -·(uχ1(w)△w)+μ1 u(1-u),x∈Ω,t >0, vt =△v -·(vχ2(w)△w)+μ2 v(1-v), x∈Ω,t >0, wt =△w +u -w -vw x∈Ω,t >0{,其中ΩRn (n≥1)是边界光滑的有界区域,χi (w)(i =1,2)为趋化敏感函数且满足χi (w)≤槇χi (1+αi w)δi ,初值 u0,v0∈C0(Ω)和 w0∈W1,∞(Ω)且槇χi ,αi ,μ1和μ2为正,δi >1。则当参数槇χi 和μ1+μ2满足一定条件时,表明此模型的初边值问题有唯一的经典解且一致有界。
