The results shows that: as the fast ions numberα=0, ie., the ions number density reduces to the Boltzmann ion distribution, the solitary waves are all rarefactive, which are in good agreement with Ref. [81]. as the fast ions increases, the compressive waves can also exist in some special regions.

结果表明，当快离子数为零时(α=0)，即离子分布退化为玻耳兹曼分布时，该系统只允许稀疏形孤波存在，这与文献[81]的结论相一致；而随着快离子数的增加(α≠0)，在某些特定的区域，还会出现压缩形孤波。

The critical nitrogen content in heading period was used to calculate the biggest accumulation quantity of nitrogen. The latent distribution index of leaf and stem, which was the variety heredity parameter, were used to distinguish the difference in nitrogen assignment in different varieties. The dynamic content of the nitrogen accumulation before anthesis could be described with a Richards model. The dynamic content of the nitrogen remobilization in leaf with leaf area index could be described with a power model, and the nitrogen absorption of grain from soil with dry weight could be described with a power model. The dynamic content of nitrogen density in stem and spike with physiological development time could be described with a nonlinear model.

模型利用抽穗期植株临界含氮量来表达氮素最大积累量，引入叶片潜在分配指数和茎鞘潜在分配指数2个品种遗传参数来区别不同品种在器官间的氮素分配差异，采用Richards方程来描述大麦花前氮素积累动态变化；采用指数函数方程来描述叶片氮的转移量随叶面积指数的动态变化以及籽粒从土壤中吸收的氮量随干物重的动态变化；采用非线性函数方程描述茎鞘和穗部的氮浓度随生理发育时间的动态变化。

The LUMO electron density geometry distribution of N-TPA1 is located on the cyanoacrylic group which favour electron injection,but for N-TPA2 it is mainly concentrated on the rhodanine framework,and resulting in the position of LUMO isolated from the -COOH anchoring group due to the presence of the -CH_2- group.

由于罗丹宁乙酸基团的羰基与五元环构架间隔一个亚甲基，使得LUMO电子分布距离吸附基团远，阻碍电子经由羰基注入TiO_2导带，这是N-TPA2的敏化电池效率比N-TPA1低的原因之一。

During the processes of uniaxial compressive failure of rocklike materials, the weakness of local material stiffness was considered to result from the distribution density decrease of bond, which was induced by the local deformation in the micro scale.

岩石类材料在受压破坏过程中，宏观上局部刚度的降低是在微观尺度上虚拟键分布密度衰减的结果。
