The article through the analysis of the various processing techniques to voice signal, in use of FFT algorithms and MATLAB language algorithms, uses MATLAB language guide orders generating graphical user interface GUI, achieves achieve real-time repeat, the plus window treatment, Butterworth filter processing and the repeat of processed voice signal and the display of spectrum analysis to voice of signals collection, functions of various window and filter characteristics analysis and display through the menus and controls of interface by the callback function for the operation; Doing them for the purposes of visibleness, audibility, visuality and intuitionistics.

本文通过对语音信号各种处理技术的分析，采用FFT 算法和MATLAB语言算法，运用MATLAB语言的GUIDE命令生成图形用户界面GUI，通过界面菜单和控件的回调函数的编写，实现对采集的语音信号进行实时回放、加窗处理、巴特沃斯滤波处理以及处理后语音的回放和频谱分析及显示，各种窗函数以及滤波函数的特性分析和显示等；达到可视、可听形象直观的目的。形成一套特色化的软件演示系统，操作简单，方便使用，形象直观，可直接用于课堂教学和实验，更一步促进上海大学的多媒体教学改革

Secondly, the combination in concept and problem teaching can enhance profound comprehension of Exclusive Events and Independent Events. Finally, because Distribution is basic knowledge in teaching probability, meanwhile, the calculation for Expected Value and Variance also are based on Distribution. Thus, Distribution is the most important in teaching them, it needs to give more emphasis.

其中计算机模拟手段在概率的频率定义教学中效果明显，并且直观模型在古典概型教学中的作用也相当明显；其次，通过概念教学与解题教学的结合可以帮助学生深刻理解互斥事件与独立事件；最后，随机变量的分布列作为概率基础知识，期望以及方差的计算都是以分布列为基础的，因而，强化分布列的教学是这部分内容的重中之重。

First, it comes from the challenge of teaching means and method-reform, for example, computer multimedia technology has become one of more important teaching tools in modern world, which has the advantages, such as intuitiveness, convenience, great capacity. This technology develops so quickly that it gets a great progress of education reform, which modernizes the teaching methods gradually.

首先是来自教学手段与教学方法改革的挑战，如计算机多媒体技术就已成为高等教育中较为重要的现代化教学工具之一，它具有直观、便捷、信息量大等优点，并且发展迅速，推动了教育教学改革的进程，使教学逐步走向现代化。

Methods According to the feature of knowledge structure in adult-upgraded students, teaching contents were changed from the traditional biology knowledge on parasitology to parasitosis knowledge. At the same time, complementing and renewing knowledge was taken into the account. To make teaching contents more direct and vivid, modem teaching media was sufficiently used. Besides, cases discussion and comprehensive thinking questions was complemented. The communication between teachers and students was advanced and the problems, which was met by the students in studying and working, was able to be solved in time.

根据成人专升本学生的知识结构特点调整教学内容，将传统的寄生虫生物学知识讲授为主转变为寄生虫病学知识讲授为主，同时注重知识的补缺和更新；改变原来单一的教学方式，充分利用现代教学媒体，直观、形象地展示教学内容，并增加病例讨论和综合思考题练习等内容；加强师生间的交流与沟通，及时解决学生在学习和工作中遇到的寄生虫学或寄生虫病学相关问题。

Intuitive principle is one of the most important principles in the teaching of physical technical abilities. The direct intuitive process with the visual idea as characteristics, the indirect visual process with the auditory idea as characteristics, and the integrative physical visual experiential process are three unseparated and interactive component parts.

直观性原则是体育技术技能教学中最重要的原则之一，以视觉表象为特征的直接直观过程，以听觉表象为特征的间接直观过程及综合本体直观体验过程是相互联系，密不可分，互为作用的三个有机组成部分。

One of the content is using efficiently multimedia computer and maths software in teaching process,and potentiating the geometrical teaching by all appearances, translating the difficulty of knowledge, strengthening the understanding of concepts. Another content is how to carry out the maths experiments, how to set up the problem for student.

研究的主要内容使如何有效地利用多媒体及数学应用软件，加强高等数学的几何直观教学，化解知识的难点，加强概念的理解；开设数学实验，创设探索数学问题的情景，培养学生探索数学问题的习惯和能力。

The demonstration experiment is one most effective object teaching method....

演示实验是一种最有效的直观教学方法。。。。

Therefore the object teaching holds the important status in physics teaching process.

因此直观教学在物理教学过程中占有重要的地位。

The paper is established in comparing the difference of the classroom instruction after actualizing music syllabus, including from making double basis the core of contents of courses to conformity and development of teaching field, from emphasizing process to result in teaching methods, from intuitionistic realia to modern educational technology in assisting teaching in teaching instruments, from teachers to students in mainstay of teaching, from unilateralism to multi-synthesis in evaluation of music classroom instruction etc., which further e...更多xpatiates the education thought of music syllabus and the important significance of students' integrative development.

文章立足于对音乐课程标准实施前后课堂教学的比较，即教学内容上从以&双基&为核心到教学领域的整合、扩展；教学方法上从重过程到重结果；教学手段上从直观教具到现代教育技术辅助教学；教学主体从教师到学生；音乐课堂教学评价从单向到多元综合等方面的综合梳理，进一步阐述音乐课程标准的教育思想及其对于学生综合发展的重要意义，对于在教学实践中深入贯彻是有着重要帮助的。
