Higher Order Effects

We study the higher-order generalized nonlinear Schrödinger (NLS) equation describing the propagation of ultrashort optical pulse in optical fibres. By using Darboux transformation, we derive the superregular breather solution that develops from a small localized perturbation. This type of solution can be used to characterize the nonlinear stage of the modulation instability (MI) of the condensate. In particular, we show some novel characteristics of the nonlinear stage of MI arising from higher-order effects: (i) coexistence of a quasi-Akhmediev breather and a multipeak soliton; (ii) two multipeak solitons propagation in opposite directions; (iii) a beating pattern followed by two multipeak solitons in the same direction. It is found that these patterns generated from a small localized perturbation do not have the analogues in the standard NLS equation. Our results enrich Zakharov’s theory of superregular breathers and could provide helpful insight on the nonlinear stage of MI in presence of the higher-order effects.

This paper mainly introduces the energy-saving control strategy for coal-fired boiler heating system. The controlled objects of coal-fired boiler heating system includes the blowers of the boiler, the induced draft fan of the boiler, the chain for coal-carrying, the primary side water circulation and the secondary side water circulation. All the controlled objects are droved by electrical motors. By the optimal frequency conversion technical, more energy and coal can be saved.
