仿真分析结果表明，由于补充卡尔曼滤波算法综合考虑了相关观测误差的影响，因此，当平滑历元数大于500时，补充卡尔曼滤波算法平滑精度要优于传统的平滑算法。

The time passed quietly for half hour, the detonation influence did not have any evanishment sign, this time the formidable shock-wave, already started to sweep away to huge Jupiter, the instantaneous entire Jupiter atmosphere, by the unprecedented formidable shock-wave, is extruded a sliver of ellipse, nearly all must have the stance which swept immediately!

时间又悄然过去了半个小时，爆炸的影响还没有任何消失的迹象，此时强大的冲击波，已经开始向对庞大的木星横扫过来，瞬间整个木星大气层，就被空前强大的冲击波，挤压成了一个长条椭圆形，几乎都要有被立即吹走的架势！

When the boundary condition described above applied, we found that there's almost no influence on pattern styles, however, influence on pattern distribution.This study can simulate concentric eyespot and wave stripe along the boundary of wing in Nymphalidae, besides, we can also simulate smaller and non-regular wave pattern which distributes over the wing.

本研究最后结合以L系统字串重建的翅脉与涂林系统，配合不同系数并将重建之翅脉作为边界条件进行蝴蝶斑纹形成研究，发现边界条件对我们所使用的四种涂林系统所产生的斑纹型态没有显著影响，但对斑纹分布则是会有一定程度的影响。

Therefore the dispersion curves obtained in the field are primarily consisted of the first mode. For a heterogeneous elastic solid consisting of three homogeneous layers whose interlayer has low velocity, the phase velocity V〓 of the first mode will also close up to the Rayleigh wave velocity of the bottom layer when frequency f→OHz, but V〓 of the first mode will close up to the shear wave velocity of the interlayer when f→∞, and there is a cut-off frequency at high frequency region for the first mode and V〓 close up to the compressional velocity of interlayer when interlayer is liquid.

当三层固体介质中存在软夹层时，若f→OHz，则其基阶模式的相速度V〓→V〓（V〓为最底层介质的瑞利波速度）；若f→∞，其基阶模式V〓→V〓（V〓为中间层介质的横波速度）；若三层介质中存在液体夹层，当f→OHz时，基阶模式V〓→V〓，而基阶模式在高频段存在一个截止频率，截止频率处的瑞利波速度V〓→V〓；由此可判定，野外实测的相速度频散曲线不仅有基阶导波模式，同时还应有高阶导波模式波的存在，接收信号中存在模式间的跳跃，因此频散曲线会产生"之"字形现象。

Know to all, The refract wave exist an precondition, that is the bottom medium velocity is bigger than upper, then medium interface produce the refractive wave, if the medium exist the speed turn in reverse, and low speed in false bottom, the medium interface can not calculate.

众所周知，折射波存在的前提是下层介质的速度一定要大于上层介质的速度，这样才能在界面形成折射波，如果存在低速夹层和速度倒转，则利用折射波来求取表层结构难以进行。
