By that time, however, the situation had greatly improved in the Eastern Church- nearly all the bishops who had taken part in the Robber Synod had now repented of their aberration and signed, in union with their orthodox colleagues, the "Epistola dogmatica" of Leo to Flavian, by this act rendering the need of a council less urgent.

到那个时候，不过，这种情况已大有改善，在东部教会，几乎所有的主教，谁参加过在匪徒的主教现在已经忏悔，他们的畸变，并签署了，在联盟与东正教会的同事，" epistola dogmatica "利奥向弗拉维安，由该法绘制需要一个会较不迫切。

MATERIALS AND METHODS: The root tips of Vicia faba were treated with different concentrations of sodium sulfite and sodium nitrite (in the concentrations of 25;50;100;200;400 mg/L) with distilled water as control for four hours.The root tips of Vicia faba were stained with carbol fuchsin and examined. The micronucleus rate and the rate of chromosome aberration were determined within root tip cells of Vicia faba.

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。

The radiuses of the atoms of Ti, W and Mo are all longer than Nis, so the lattice aberration of Ni decreases with the increasing CNTs addition, and relevantly the glancing angle increases, accordingly the diffraction peaks move to the right.

而Mo，W，Ti的原子半径都比Ni的大，所以Ni的点阵畸变减小，晶格常数随之减小，X射线的掠射角随之增大，衍射峰右移。

The motion, creation and annihilation of phase singularities in the focal region take place, which depends on the truncation parameter, spherical aberration and half angle of the aperture lens.

在焦区位相奇点会出现移动、产生和湮灭，并与截断参数、球差和光阑透镜半角有关。

The stress was the study of the new methods of calculation the harmonic voltage and the harmonic current, and a new concept of filter ratio to evaluate the actual effect of single harmonic filter was raised considering the background harmonics. As well, the calculation mode of the single harmonic filter was also given based on the concept of filter ratio; it can offer effect data to evaluate the actual filter ratio of the single harmonic filter. At the same time, a method of designing the single harmonic filter was given, too, considering the background harmonics of the power system. In this paper, both the computer analysis and the proven had been done. And the result was shown to be that the voltage aberration and the harmonic current were decreased, and that the actual filter ratio of single harmonic filter was raised. The reason that we must consider the background harmonics when designing a single harmonic filter was also expatiated in this paper.
