Chapter 2、When treat propagate problem of high power laser beams, ordinary assume beam to be ideal plane wave or Gaussian. Actually, beams is not ideal Gaussian or plane wave. The reason is that is phase aberraed and intensity nonuniform. In this chapter, we have developed a method on frequency conversion of aberrated beam. Based on statistical optics method and within the limits of thin crystal, we have studies on second harmonic generation of the phase aberrted beam. And the phase aberration is assumed to be a Gaussian random variable.

第二部分：在处理高功率光束传输问题中，通常假设光束为理想平面波或高斯型，而实际光束都不可能是理想的高斯光束或平面波，均会有一定的位相畸变及光强不均匀，本部分从统计光学的观点出发，在薄晶体近似下，建立了具有高斯型随机相位畸变光束倍频转换的一种统计描述方法，并对倍频转换光束的横向空间特性进行了分析。

By using electrophoresis analysis of seed gliadins, the specific bands of E. intermedia were discovered in electrophoretogram of 6 octoploid Trititrigia, the band types of Shannong TE183, Shannong TE185, Shannong TE198, Shannong TE256 and Shannong TE347 are basically the same, and that of Shannong TE188 is different from the other 5 octopliod Trititrigia mentioned above .

种子醇溶蛋白电泳分析证明，6个八倍体小偃麦醇溶蛋白图谱中均具有亲本中间偃麦草的特异带，并且山农TE183、山农TE185、山农TE198、山农TE256和山农TE347等5个八倍体小偃麦的带型基本一致，为同一类型，而山农TE188为另一类型。

Octoploid tritielytrigia type TAI-7045 showed immunity to yellow rust and middle resistance powdery mildew. CH-9916 is immune to yellow rust in seedling and adult stages, powdery mildew in seedling and adult stages, and their powdery mildew middle resistance. These suggested that the high powdery mildew-resistance in Octoploid tritielytrigia TAI-7045 had probably been transferred into common wheat.

通过对条锈病及白粉病抗性评价，结果表明：亲本八倍体小偃麦TAI-7045、小偃麦衍生系CH-9916对条锈病表现免疫，对白粉病表现中抗，而另一亲本"晋麦33"对条锈病、白粉病表现高感，推测小偃麦衍生系CH-9916抗条锈病及白粉病的基因均来源于代换的一对染色体——亲本八倍体小偃麦TAI-7045即来源于中间偃麦草。

After undergoing a chaotic region, the period number will add one, in the same time, magnitude of the subharmonic response increases in sequence as the rotational speed ratio increases. When the rotational speed is below the critical speed, the chaotic bands resulted directly from a perioddoubling bifurcation occur among the successive orders of superharmonic responses, then they can return directly to periodic motion by a reversed period-doubling bifurcation.
