In this paper, the coupled higher-order nonlinear Schrodinger (CHNLS) equations governing the ultrashort soliton pulse transmission in a two-mode or birefringent fiber are studied. The dark double-hump (DDH) three-solion solutions with higher order effects are derived by the Hirota method. Based on the solutions, the elastic collisions of DDH solitons, the anti-dark solitons and anti-dark soliton molecule are revealed in two modes. The differences of collision dynamics are discussed when three solitons colliding sepa-rately and simultaneously. We find the soliton molecule bound by anti-dark, kink and anti-kink solitons. Moreover, the effects of the group velocity dispersion (GVD), self-steepening (SS) and third-order disper-sion (TOD) on the collisions are analysed. Those researches are valuable to the development of ultrashort pulse fiber laser and optical fiber communication. We also hope that those results contribute to the study of soliton molecules.

We study the effective amplification of optical solitons in high power transmission systems based on a nonlinear Schrödinger equation with variable coefficients. Three soliton solutions to this model are constructed analytically. We analyze the characteristics of three soliton interaction and achieve the effective amplification of solitons. We analyze the influence of parallel and nonparallel propagation of optical solitons on optical soliton amplification. The conclusion of this study is beneficial to the propagation and amplification of optical solitons in high-power transmission system, so as to effectively improve the transmission distance of the system.

In this paper, a variable-coefficient nonlinear Schrödinger equation that describes the optical soliton propagation in dispersion management fiber systems is studied. Two- and three-soliton solutions are obtained by using the Hirota bilinear method. Based on those solutions, the effects of related parameters on optical soliton propagation are discussed. By choosing different values of the third-order dispersion, the amplification of optical solitons can be realized. In addition, the interactions among the solitons can be reduced by setting a proper value of the group velocity dispersion. The results of this paper may be helpful to design optical amplifiers or to improve the quality of optical communications.

The (2+1)-dimensional generalized coupled nonlinear Schrödinger equation with the four-wave mixing (FWM) term is studied in this paper, which describes the optical solitons in a birefringent fiber. By virtue of the Hirota method, the one- and two-soliton solutions are derived. On the basis of solutions obtained, we discuss how the values of the FWM and some free parameters affect the solitons’ peformance. The FWM parameter can help to control the amplitude of the solitons. Meanwhile, by setting the values of certain free parameters, we can control the solitons’ propagation direction and speed, and reduce the interactions between them as well. In addition, the energy transfer of solitons during elastic collision and separation is also discussed. The conclusions here may be useful in improving the communication quality in multi-mode fibers.

Results have some potentially applications in optical fibers and the design of optical switches.

Research on the interactions between optical solitons is of great significance for the large capacity and long distance transmission in optical fibers. In this paper, interactions between periodic solitons are investigated for the first time. Analytic solution for the high-order nonlinear Schrödinger equation, which can be used to describe the periodic soliton transmission, is obtained based on the bilinear method. Interaction characteristics between periodic solitons are discussed. Influences of corresponding dispersion and nonlinear effects on their interactions are analyzed. Results provide theoretical guidance for the stable transmission of periodic solitons in inhomogeneous optical fibers.

This work studies a new (3+1)-dimensional nonlinear model, which was introduced by Abdul-Majid Wazwaz in 2014. This new physical model describes the shallow-water waves and short waves in nonlinear dispersive models. Analytical traveling wave solutions including the solitons and plane wave solutions are derived by using the G'/G-expansion technique. Moreover, the conserved quantities of this model are also given.

In this paper, a generalized nonlinear Schrödinger equation with variable coefficients is investigated. According to the analytic soliton solutions, the dromion-like structures between soliton interactions are revealed, and interaction properties are discussed. By changing the values of gain/loss, group velocity dispersion and self-phase modulation parameters, influences of them on interaction intensity and phase of solitons are presented. Besides, methods of controlling the path and spacing of solitons are suggested. Results of this paper may be potential valuable to the study of soliton interactions in inhomogeneous optical fibers and have applications in all-optical switches.

As the optical transmission system is developing in the direction of ultra-high speed and ultra-long distance, the dispersion and nonlinearity of optical fibers has an increasing influence on signal transmission.

Analytic soliton solution is derived, and M-typed solitons are observed. The improvement of system performance is analyzed. In addition, a nonlinear control method is proposed based on the analysis of corresponding parameters.

The promotion of deep counseling is an important measure to improve the substantial results of the moral education in universities and to serve for enhancing the students' individu-ality development and self-actualization, which is also an essen-tial skill to effectively carry out the work of college counselors. This article applied the theories and methods of psychological counseling to discuss three common problems in deep counseling combined with cases, and to provide new ideas for the further de-velopment of deep counseling.

Teacher motivation not only has a close relationship with teaching behavior and teacher professional development,but it also impacts students' perception about teaching and their academic performance.Based on the review of three motivation theories and relevant research,this paper summarizes the relation and difference among these theories and points out five prospects for the future research on teacher motivation,such as theoretical construction,and antecedent effect in empirical research.

The study applied ＂Work-Family Conflict Inventory of Primary and Secondary Teachers＂ and ＂Burnout Inventory of Primary and Secondary Teachers＂ to investigate 223 primary school teachers.By clustering analysis,primary school teachers＇ work-family conflicts could be classified into four types named harmonious type,family type,conflict type and work type.Teachers of both genders show significant differences in the distribution of the four types respectively.Females have larger number of family type and harmonious type,while males with larger number of harmonious type.Teachers of a teaching age lower than 5 and 20~40 both have significant distributions of more harmonious type;while 11~20-teaching-age teachers show more family type.These four types of teachers have different characteristics in the three dimensions of burnout.
