If ris also irreducible in Z_nand f~n~κ≡fmodn,r(xfor all f∈Z_nthen we call n a Carmichael number of orderκmodulo r.Denote the set of all such numbers by C_κ,r(x.Define C_κ=∪_r(xC_κ,r(x,where rpasses through all monic irreducible polynomials over Z of degreeκ.We call elements of the set C_κCarmichael numbers of orderκ.ZHU and SUN[Journal of Sichuan University,42;1(2005), 47-51]first gave a necessary condition for Carmichael numbers of order 3.Then they gave a sufficient condition for Carmichael numbers of order 3,but did not find any such numbers less than 10~8 satisfying the sufficient condition.At last,they asked three questions;1.is the necessary condition also sufficient?

f∈Z_n，就称n是模r的κ阶Carmichael数，用C_κ，r(x表示所有这种数的集合，定义C_κ=∪_r(xC_κ，r(x，这里r跑遍Z中所有κ次首一不可约多项式，C_κ里面的元素就称为κ阶Carmichael数，C_κ称为κ阶Carmichael数集，朱文余和孙琦[四川大学学报，42；1(2005)，47-51]首先给出了3阶Carmichael数的一个必要条件；然后又给出了这种数的一个充分条件，并发现10~8内没有满足此充分条件的这种数；最后他们提出三个问题；一、问必要条件是否也是充分的？

Indeed, between the forms of the leaf-covered monopode first encountered, and this monstrous leg, we recall iconic scenes of flight, common amongst grand Renaissance tableaux, one particularly good example being exemplified in Michelangelo's Last Judgement by the bottom right-hand section, which is known as the Boat of Charon—a fitting allusion because Charon was the boatman who delivered the damned into the mouth of hell from which they were presumably anxious to escape, hence the animated energy brought to their flight.

的确，在先前体验过的叶子覆盖着的独脚和这只巨腿的两种造型中，我们忆起典型的逃离场景构图，是文艺复兴艺术的大型静态画面中常见的，而米开朗琪罗的《最后的审判》右下角所谓"卡戎的冥河之船"那部分就是特别典型的代表范例；这个典故在此极为恰当，因为卡戎就是将被打入地狱的人送往阴府的船夫，他们自然急于逃跑，因此才有这些人物脱逃的激动镜头。

At last a brief introduction for the research history of WE and impedance inversion is given. In chapter 2, at first, the seismic deconvolution model is linked with the moving average process, the method for determination of wavelet length is developed which use the singular values of high-order cumulant matrix of seismic traces.

Some conclusions are inducted through the study: first, grid nudging with the rountine observed data in the MM5 simulation of atmospheric duct affects less over the sea than the land;Second,how much of sigma levels have great influence on simulation of atmospheric duct and the MM5 simulation with more sigma levels depicting the atmospheric ducts are reasonable; Last, multiple nests are allowed on a given level of nesting domain in the MM5 model.

通过研究得到了以下结论：(1)利用常规资料进行格点同化对海上大气波导影响较小，对陆地影响较大；(2)垂直分层对大气波导特征参数影响明显，层数较多描述大气波导比较合适；(3)对于海上大气波导，细网格刻画大气波导特征参数比较细致，但粗网格的模拟已经足够进行大气波导分析。
