THE LIMIT CYCLE SOLUTION OF PREY-PREDATOR EQUATION WITH SELF-RESTRAINT EFFECT
具有食饵自身抑制作用的Volterra方程的极限环解

Using bifurcation theory the property of solution of Volterra prey-predator equation with self-restraint term is discussed. The results show that if the sign of coefficient in restraint term is allowed to vary, then b = 0 is a bifurcation point. At this point will create the bifurcation solution of limit cycle. But this solution had been omitted in usual way.
