Dynamic drying processes are obtained and a series of moisture phase distribution images are drew using computer simulation . images clearly show fractal drying front . a strange drying phenomenon that moisture transfers not only from inner to outer , but also from outer to inner of porous media is observed 通过相图分析还可以发现,干燥中内部湿分的迁移不仅是一个从里到外的过程,到了一定的干燥阶段,也同时存在由外到里的干燥现象。
And we did the theoretical analysis with lcd cell to achieve the phase distribution of coe . that will bring reference meaning to the designation of the computer optical elements . in chapter 5 we proved the accuracy of the design theories and the theoretical deduces through the experiments with film and general lcd cell 文中对上述两种设计理论得到的模拟结果进行了比较,得出有一定参考价值的结论,随后对利用液晶相位改变原理实现之前设计的相位分布进行了理论和实验的探讨,对今后设计计算机光学元件具有参考性意义。

It shows that when walk - off and diffraction effects could be ignored approximately estimation of the phase distribution of second - harmonic wave could be done . the far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave , but the far field divergent angle will be obviously smaller than that of fundamental wave . the phase distribution of both fundamental and harmonic wave is measured using hartmann - shack wave front sensor in the experiment with 1064nm and 790nm lasers , respectively 这说明利用非线性光学频率变换方法拓宽波前传感器件的响应波段是很难实现的,但是,通常三波相互作用过程的研究均是建立在平面波和理想高斯光束之上,因此我们对于位相畸变倍频过程的研究是非线性光学领域一个重要而有意义的新课题,它有助于人们更加深入理解非线性光学效应,为进一步合理利用之奠定了理论和实验的基础。
