  “caseii扩散”译为未确定词的双语例句
     These results indicate that diffusion of MMA into PMMA has some characterization of Case II, i.e., accumulating diffusion concentration increasing with diffusing time linearly and advancing diffusion front with a constant velocity, but it does not totally belong to Case II since the concentration within swollen rubber state part located on the back of the advancing front is not fully the same.
     通过分析可以知道,MMA在PMMA中的扩散显示了CaseII的一些扩散特点,即其累积的扩散浓度随时间线性增加以及其扩散前沿以恒定的速度前进,但它又不完全是CaseII扩散,因为在扩散前沿后部的橡胶态中浓度并不完全相同。

To understand the mechanism of anomalous diffusion phenomena, which are often observed in polymer-related diffusive system, it抯 essential to build a technique to visualize the diffusion process, To realize this purpose, the laser holographic interferometry was introduced and applied to record the diffusion process of MMA in PMMA. Through processing of holographic interferogram gotten, the concentration distribution can be obtained, also, for the advantage in this imaging process, the diffusion front (the interface of swollen part and un-swollen one of polymer) can be resolved. These results indicate that diffusion of MMA into PMMA has some characterization of Case II, i.e., accumulating diffusion concentration increasing with diffusing time linearly and advancing diffusion front with a constant velocity, but it does not totally belong to Case II since the concentration within swollen rubber state part located on the back of the advancing front is not fully the same. The study shows that, the holographic interferometry can be used to realize the visualization of diffusion process, especially for high viscous systems, like polymer system, since the non-homogeneity inherited from high viscous system and resulted from diffusion process(concentration distribution) can be discriminated, the errors caused by the non-homogeneity of high viscous system can be avoided, and it also does not need to break the measured media. So it is a kind of non-intrusive method.

高分子体系中的扩散通常显示了反常扩散现象,为了理解其机理,建立该过程的可视化技术是必要的。今利用激光全息干涉技术来实现该目的,介绍了激光全息干涉技术的测量原理,并把它应用于甲基丙烯酸甲酯(MMA)在聚甲基丙烯酸甲酯(PMMA)中的扩散过程的记录。通过对所得全息干涉图的处理,得到了浓度场分布;由于全息干涉的优势,它还能分辩出扩散前沿(即被小分子物质溶胀部分与未被溶胀的高分子本体的分界面)。通过分析可以知道,MMA在PMMA中的扩散显示了CaseII的一些扩散特点,即其累积的扩散浓度随时间线性增加以及其扩散前沿以恒定的速度前进,但它又不完全是CaseII扩散,因为在扩散前沿后部的橡胶态中浓度并不完全相同。因此,全息干涉技术可以实现扩散过程的可视化,特别对于高分子体系这种高粘体系,很容易出现局部的不均匀性,这样其它的一些测量方法可能无法区别开来这个不均匀性和由于扩散过程所导致的不均匀性(分布),而在全息干涉技术上则可以区别开这两者。因此它避开了可能引起的测量误差,同时它还不破坏测量场,是一种无损检测。
