摘要
研究了可逆三分子反应模型:.x=-A1x+A2x2+A3y-x2y,y.=y(x2-1);证明了当A1>2A2A3/(1+A3)时,其极限环的存在性;当A1>2A2A3/(1+A3),A1>A3,A3<5A12/(9A22)时,其极限环的唯一性。
In this paper we consider the a bio-chemical reaction system: x = - A1x + A2x2 + A3y - x2y, y = y( x2 - 1 ). The following results are proved: When A1 〉 2A2A3/( 1 + A3 ), there exists a limit cycle of the system; When A1 〉 2A2A3/( 1 + A3 ) ,A, 〉 A3 ,A3 〈5AI2/(9A2^2 ) , there unique limit cycle of the system.
