Selecting proper single valued variable separation functions in the 2+1 variable separation solutions,we construct many types of single valued coherent soliton structures such as dromion,dromion lattice,solitoff,2-solitoff,static and kinetic breather,instanton,compacton, peakon,and so on.The interactions among these coherent localized excitations including the collisions of compaction and compacton,peakon and peakon,line soliton and y-periodic soliton,dromion and dromion,dromion and solitoff,et al,are investigated analytically and graphically,and found that can be elastic and nonelastic respectively,which reveal various exotic and important nonlinear characters and interaction properties.

在2+1维分离变量解中选择适当的的单值分离变量函数，构造了2+1维非线性波动模型多种单值相干孤子结构如Dromion，Dromion格子，Solitoff，2-Solitoff，静止和运动呼吸子、瞬子、Compacton、Peakon等；考察了一些典型的非线性激发模式间如Compacton和Compacton，Peakon和Peakon，线孤子和y-周期孤子，Dromion和Dromion，Dromion和Solitoff之间等相互作用行为，发现其相互作用可以弹性的也可以是非弹性的，揭示了多样奇异而重要的非线性特性。

The molecular basis for the virulence of this virus is still poorly understood. We characterized two H5N1 subtype viruses, A/mallard/Huadong/Y/2003 is nonpathogenic to mallard whereas A/mallard/Huadong/S/2005 is highly pathogenic to mallard.

This paper determined the olfactory respones of Tetranychus viennensis to different plants odors with "Y" olfactometer and petri-dish, volatiles from leaves of different plants were absorbed with SPME and analyzed with GC-MS (gas chromatograph-mass spectrometer).
