 THEOREM OF EXISTENCE OF EXACT n LIMIT CYCLES IN ||≤(n+1)π FOR THE DIFFERENTIAL EQUATION +μsin+x=0
 张芷芬
 　　<正> In this paper,it is proved that the differential equationor its equivalent systemhas exact n limit cycles on the strip region |v|≤(n+1)π of the phase plane (x, v)(n = 1, 2,...). This conclusion is obtained for a more general equation of Lienard's type.
