In this thesis,we consider the problem basing on the Picard-Fuchs equationand bifurcation theory,also using known methods and techniques.We establish therelationship between the number of zeros of the Abelian integral and the number ofintersection points of the"centroid curve"with any straight line.

本文以Picard-Fuchs方程和分岔理论为基础，充分利用已有的方法和技巧，把对Abel积分零点个数的研究转化为对"质心曲线"和任意直线交点个数的研究。

For the case of n=2 and X〓 is generic, by using Picard-Fuchs equations and the argument principle Horozov and Iliev [36] gave the least upper bound of the number of zeros of I under the condition that X〓 has one center and three saddles.

当n=2且X〓为通有的Hamilton系统时，Horozov和Iliev[36]利用幅角原理和Picard-Fuchs方程给出了当X〓有一个中心、三个鞍点时I零点上确界的个数。

Recently. by complexification of the space and time variable, also using the Picard-Lefschetz theory, argument principle, Riemann manifold and homology theory, Gavrilov [25] proved the same result under the condition X〓 has one center and one saddle or two centers and two saddles.

最近Gavrilov[25]将方程复化后利用Picard-Lefschetz理论，幅角原理及同调论等工具得到X〓有一个中心、一个鞍点和两个中心、两个鞍点的情形下I零点个数的上确界。

To complete the proof, we use some known methods and techniques, based on the Picard-Fuchs equation and bifurcation theory, and develop some new methods and techniques.

为了完成上述证明，我们除了以Picard-Fuchs方程和分岔理论为基础，充分利用已有的方法和技巧之外，还发展了一些新技巧和新方法。

Under some moderate conditions, the prior estimate of the solutions of the system is obtained. Making use of constructing Picard iterative sequence, Doob martingale inequality, Gronwall inequality, Borel-Cantelli lemma and some fundamental inequalities, together with the uniform Lipschitz conditions, the existence and uniqueness of the solution for stochastic functional differential equations with infinite delay is derived on the interval t0,∞.

在适当的条件下，得到了随机泛函微分方程的解的先验估计；再结合一致Lipschitz条件，通过构造Picard迭代序列，利用Doob较不等式、Gronwall不等式、Borel-Cantelli引理及一些基本不等式，得到该方程的解在区间[t0，∞]上是存在且唯一的。
