Special soliton structures and the phenomena of fission and annihilation of solitons for the (2+1)-dimensional Broer-Kaup system with variable coefficients;
变系数(2+1)维Broer-Kaup系统的特殊孤子结构及孤子的裂变和湮没现象
The results show that third-order soliton will be compressed and splited in the propagation and the interaction of two third-order solitons can quicken the split.
用分步富里叶变换法求解三阶孤子传输的NLS方程,得到了在此条件下孤子传输的数值图形,发现三阶孤子在传输中被压缩和裂变,三阶孤子的相互作用加速了孤子的裂变。
The paper analyzes the split of the personality in Ralph of The Thorn Birds from the angle of humanity and divinity,and the main causes for such split from the religious background,socio-historical background and Ralph s personal weaknesses are explored.
