研究了一类具有六次轨道的二次可逆Lotka-Volterra系统的周期环分支极限环。利用推广的完备Chebyshev系统的性质，证明了周期环在二次扰动下的周期性等于2。
This paper is concerned with limit cycles which bifurcate from a period annulus of a quadratic reversible Lotka-Volterra system with sextic orbits. The authors apply the property of an extended complete Chebyshev system and prove that the cyclicity of the period annulus under quadratic perturbations is equal to two.
