This paper is devoted to the study of bifurcation phenomena of double homoclinic loops in reversible systems. With the aid of a suitable local coordinate system, the Poincaré map is constructed. By means of the bifurcation equation, we perform a detailed study to obtain fruitful results, and demonstrate the existence of the R-symmetric large homoclinic orbit of new type near the primary double homoclinic loops, the existence of infinitely many R-symmetric periodic orbits accumulating onto the R-symmetric large homoclinic orbit, and the coexistence of R-symmetric large homoclinic orbit and the double homoclinic loops. The homoclinic bellow can also be found under suitable perturbation. The relevant bifurcation surfaces and the existence regions are located.

可逆系统中双同宿环的分岔

本文致力于研究可逆系统中双同宿环的分岔现象。借助合适的局部坐标系，构建庞加莱地图。借助分岔方程，我们进行了详细的研究，取得了丰硕的成果，证明了在主双同宿环附近存在新型R对称大同宿轨道，存在无限多R对称周期轨道累积R对称大同宿轨道，R对称大同宿轨道与双同宿环共存。在适当的扰动下也可以找到同宿波纹管。定位相关的分岔面和存在区域。
