光折射的临界角定义：光折射角=90度时，入射角即为临界角，按二方法，将半导体激光光源去掉铁夹，吸附在右下角的铁板上入射光对准中心，即产生折射光线，沿半圆形柱面移动光源，改变入射角的大小，这时折射角也改变，当折射角=90度时，这时入射角即为临界角，水的临界角大的在40度左右，再做移动光源在水中的水屏即出现反射光线，这种现象称全反射。

充分运用现代教学技术武装我们的教学，对原有的教学生产方式来一场革命，这是教育实践的呼唤，也是时代的呼唤，本论文从多媒体在英语课堂教学中的作用出发，来说明运用多媒体进行计算机辅助教学的作用： 1 在英语课堂教学中的作用 1.1 丰富教学内容改变传统教学的单调模式 1.2 激发学习兴趣促进学习动机 1.3 变被动学习为主动学习有效体现教学的个体化和因材施教 1.4 为教师提供形象的表达工具有效地减轻学生的课业负担 2 现代教育中的作用 2.1 弥补不同学校、地区之问教学质量的差异 2.2 改善教学管理过程改进教学效果 2.3 丰富的课外读物 2.4 多媒体技术与网络技术的结合可有效地开展远距离教育正因为多媒体具有这么多的优点，所以许多学校多投资兴建了校园网和多媒体教室，如何设计和制作高质量的多媒体课件是许多学校迫切需要解决的问题，所以本文接下来谈论的是如何设计和制作多媒体课件以及在设计和制作过程中如何应用心理学上的注意规律等，仅供各位同行参考。

In the light of the palenenvironmental significance reflected by the radiolaria, graptolite, brachiopod, sponge spicule and the rock character, it's suggested that the grayish green mudstone at the basal Wufeng Formation of the Goujiaya section would be probably deposited in 60 to 100meters deep water, the Guanyinqiao bed in 50 to 80meters deep, and the radiolaria-bearing silicalite from Wufeng Formation in water with 200 to 400 meters deep. Combining the above-mentioned water depth with the sea-level change cycles, the change range of every one of the 5 cycles could be further conjectured. They were in ascending order: 20～120m, 80～130m, about 150m, 50～250m, and in excess of 200m.

根据放射虫、笔石、腕足类、海绵骨针以及岩性等对古环境的指示意义，认为五峰组底部灰绿色泥岩段产出时水深约60-100m，观音桥层水深约50-80m，在晚奥陶世最大海侵期(对应于T.typicus亚带下部)，水深约400m，五峰组含放射虫硅质岩沉积时最小水深约200m，结合以上海平面变化的5次旋回，从而推算出各旋回海平面的变化幅度：在第①旋回，海平面变化范围大致为20～120m；在第②、第③和第④旋回中，海平面变化分别为80～130m、大约150m和50～250m；第⑤旋回的海平面升降幅度大于200m。

Lastly, we summed up the law about the change of maximum dry density, optimum water content, angle of internal friction, cohesion, unloaded expansion capacity, compacting factor, height and speed of capillary rise, frost heave and salt expansion capacity with the change of silt-clay content. Besides, we analyzed the result.
