摘要：
<正> The results of this paper are as follows: （ⅰ） For the planar cubic system （E）α, the existence on distribution of limit cycles with the structure （1） + （1） + （1）(（1） + （1）)has been proved. （ⅱ） For the non-linear oscillators （1.1′） and （1.2′） without xg（x）>0, some sufficient conditions on the existence of limit cycle containing more than one singular point in its interior are given.
