The diffraction theory of Kirchhoff is applied to the four-pinhole aperture diffraction screens, the intensity, the zero-contour of the real and imaginary parts of complex amplitude and the phase distribution in deep Fresnel diffraction region are simulated, and it is found that the bright spots in interference field show central symmetry distribution. When the observation plane close to the diffraction screen, the zero-value points of light intensity can form line segment, on which the eccentricities of the light intensity isoline are close or equal to 1, the intensity changes very fast on both sides of the zero-line of light intensity.

利用基尔霍夫衍射理论计算了四圆孔径衍射屏在菲涅尔深区形成的的干涉光场的强度、零值线和相位的分布，发现干涉光场亮斑关于中心呈对称分布，在距离衍射屏较近的观察面上，光强值为的零点组成光强零值线段，该线段上光强等值线的离心率都接近或等于1，其两侧的光强值变化非常剧烈。

The phase of optical wave can be recovered by the intensity transport equation under the paraxial approximation For the optical system with diffraction limit, it is difficult to get the boundary radical slope of phase and sample in the circular domain boundary when using the intensity transport equation to recover the phase, consequently, we reviewed an algorithm mentioned in the reference ［4］, namely, the equation, computation domain and boundary condition are changed, then the phase is reconstructed by the multigrid method and corrected at last Moreover, the experiment system is set to testify the algorithm, and the recovered phase from the intensity data detected by CCD is compared with the result from phase retrieval algorithm, it is found that the phase reconstruction error can reach 017 λ in the case of non-uniform intensity distribution, as a result, the method is suitable for the phase recovery with low wavefront sensing accuracy.

在傍轴近似条件下，可以利用光强传播方程对畸变波前进行相位恢复。对于衍射受限的光学系统，很难获得相位的边界径向斜率值作为边界条件，此外，要获得精确的圆域边界采样值也并非易事。为了克服上述困难，进一步研究了相位恢复改进方法，即改变了方程的表示形式、计算区域和边界条件，并用多重网格法进行求解获得重构相位，最后再将其修正。为了验证算法的精确性，搭建了实验系统对算法进行实验验证，将由CCD探测的光强分布进行计算得到的相位分布与相位恢复算法的结果进行比较，证明在光强分布非均匀的情况下，该方法恢复的相位均方根误差能够达到017 λ，可以适用于波前传感精度要求不是很高的相位恢复。标签自适应光学相位恢复相位修正光强传播方程 adaptive optics phase retrieval phase correction intensity transport equation

However there are some differences in the learning motivation in terms of different backgrounds:① The higher the academic degree holders, the lower the intensity of the learning motivation in self-development, social contact, family requirement and degree pursuing.② The students from town and villages show great motivation in Better Serving Society, however the students from cities pay more attention to the assessments from family and working company.③The intensity of the motivations in female students in pursuing knowledge, self-development and social contact are apparently stronger than male students.④With the increasing of age, the motivation intensity decreases in the aspects of self-development, career-development and competition or promotion. The students in the age of 40"s to 50"s pay more interests in educating children.⑤The motivation intensity in Better Serving Society, Avoid Failure in The Work and Better Educating Children decreases with the increasing of the income. Middle income class emphases more in promotion.⑥ The intensity of motivation in pursuing knowledge is very strong in state-worker and free-lancer. Teachers pay more attention to career development and the free-lancer emphasis in developing enterprises and self-expressing.

In sparkle discharge ,following conclusions could be reached:(1) overall spectral intensity in nitrogen is lower than in oxygen . When water is added, integrality light intensity is lower compared with the pure gas condition.(2) No matter it is nitrogen or oxygen, when water is added, syllabify three spectral lines of atomic H: Hα(656.3nm), Hβ(486.1nm), Hγ(434.0nm) could be seen. What is more, when water is added into oxygen, the spectral line of H atom becomes stronger.(3) When discharge in pure nitrogen, the light intensity falls with the increasing gas flow rate. While if water is added, the light intensity will rises with the increasing gas flow rate.(4) When discharging in pure oxygen, the light intensity rises with increasing gas flow rate. While if water is added, with increasing gas flow rate the light intensity initially will change as this:first rise, then saturate at about 140l/h, finally falls.
