Tins article will tell us the functions of CAI in English classroom teaching:1. the functions in English classroom teaching1. 1 enrich the teaching contents and change the monotonous design of traditional teaching1. 2 arouse the students interest and stimulate the studyintention1.3 make initiative study change into passive study1.4 lighten the students schoolwork2. the functions in modern education2. 1 remedy the differences between different schoolsand areas 2. 2 improve the process of teaching management2.3 enrich the reading matter of the outside class2.4 develop the long-distance education by using the multimedia and internet technologyBecause there are so many advantages about multimedia. many schools construct campus net and multimedia classrooms. Then designing and making CAI software became an important problem for these schools, so these article can tell us how to design and make it. In order to make CAI software better, the articled also tell you how to pay attention to something .That is the content of my article , I hope I ran consult it with you .Thank you.

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。

objective in order to exploit the natural resources of chinese herbs,the inhibitive effects of the compositions of28chinese herbs on the growth of8common bacteria in oral cavity were determined.methods sen-sitive test of these bacteria were carried out by mtt method.at the same time,chessboard dilution method was used for combined sensitive test.results the compositions of28chinese herbs can inhibit the growth of5bacteria in dif-ferent levels,but the effects on other3bacteria are not obvious.quercetin and usnic acid have better effects on5bacteria than other26herbs compositions,with mic0.03125～0.125mg/ml and0.0156～0.0625mg/ml.conclu-sion quercetin and usnic acid can inhibit the5bacteria growth more effectively than other26herbs compositions.

目的 测试28种中药有效成分抑制8种口腔常见致病菌的作用，为抗菌中药有效成分用于口腔感染性疾病的防治做一些探讨。方法选择28种有抗菌作用的中药的有效成分，采用噻唑蓝法对8种口腔常见致病菌作药物敏感实验，同时采用液体棋盘稀释法进行联合药敏实验。结果 28种中药有效成分对3种牙周细菌抑制作用不明显，对另5种口腔常见细菌有一定的抑制作用，其中松萝酸和槲皮素有较强的抑菌作用，mic值分别在0.0156～0.0625mg/ml和0.3125～0.125mg/ml之间。结论所选28种中药成份中，松萝酸和槲皮素具有较强的抑菌作用。

By doing these, the theory of effective classroom teaching would be afforced and fully developed.

一方面，对熵理论在初中化学课堂有效教学的应用研究是对有效教学理论的丰富和发展；另一方面应用熵理论指导初中化学教学实践，在教学过程中充分把握初中化学教学系统的开放性特征、非平衡特征、&自组织&现象进行初中化学有效教学，将有助于我们进一步改善教学方法，优化教学手段，真正意义上实施有效教学，从而提升学生的化学科素养，充分发挥学生的潜能，促进初中新课程的顺利实施，推进素质教育。

It adopts the single chip computer control calculation meritorious service capacity, and parameters such as real power, reactive power, meritorious service rate element, tension fundamental harmonic virtual value and tension harmonious wave virtual value and so on these are separation to the calculation branch to the measurement that on the basis of the scattered integration formula in immediate future scattered Fourier transformation, the exchange basseted on to power system parameter sampling idea was achieved to adjust all the journey moreover the frequency alternating current frequency and the tension virtual value as well as the electric current virtual value in the way of software .

If we want to get the effective mass by the method of computing the meson self-energy , we need to consider the change of the effective mass of the nucleon along with the increasing density of the nuclear matter,namely considering the fluctuation of the vaccum.

很多研究[3，4，5，6，11，12]表明了上式描述的规律是正确的，如果用计算介子自能的方法来得到介子的有效质量，需要考虑核子的有效质量的随核物质的密度的变化，即需要考虑核子的真空涨落，当不考虑核子有效质量随核物质密度变化的时候，ρ介子、ω介子的有效质量一般是上升的。
