直观教学

In research and teaching of elastic collision of two particles,with the help of the graphical method, the effect is more audio-visual, imaginal,succinct and thorough.

两个粒子的弹性碰撞问题，若辅之于图解法，则对问题的研究、讨论以及课程教学等，都显得更加直观、形象、简洁和透彻，充分体显出它的优越性。

Experiments indicate that the system is easy-to-use and reliable in the operation,can be used in teaching,testing and fault diagnosis.

通过实验验证，该系统使用方便、性能稳定、工作过程形象直观，既能在教学中使用，也可用于测试和故障诊断。

The demonstration experiment is in chemistry teaching one of most commonly used intuitional means.

演示实验是化学教学中最常用的直观手段之一。

The practice proved that the test system for force signal in the automobiles based ob VB is intuitionist and easy to operation and procured the good teaching result.

实践证明，基于VB的汽车中力信号测试系统界面直观，便于操作，取得了很好的教学效果。

For such a single-input-two-output unstable system with strong nonlinearity and strong coupling,the control scheme was accomplished by adding a tracking differentiator and the feedback control law comprised of the errors of the two controlled variables,instead of the only one in the usual ADRC scheme. This method expanded the range that the ADRC scheme can deal with.

倒立摆系统以其结构简单直观，构件参数和形状易于改变，成本低廉，而本身又是一个高阶次、不稳定、多变量、非线性、强耦合系统，被公认为自动控制理论中的典型试验设备，也是控制理论教学和科研中不可多得的典型物理模型。

In this article, the "instructional software for illustrating the assembling and disassembling process of one-level speed reducer" is designed by applying Visual Basic programming software.

计算机辅助教学，将教师难以用语言和黑板表达的复杂的机械结构，应用多媒体技术以多样化的方式表现在屏幕上，达到了以直观和形象的形式为学生提供机械设计的知识的目的。

The superiority of audio-visual education lies in individualism, interactivity, huge information memory and rapid running speed.

电化教育优于传统的课堂教学在于其因势利导的"个别化"，生动直观的"交互性"，巨大的信息存储量，快捷的执行速度等。

The images haoe the characteristics of audio—visualizatiou and vividness. And it plays an vital rde in stuhent zvderstarding susofale features of geography matters,mastering the spale distribution lavo of geography matters and analyzing the inner relation betroeen the elements of gecgraphy matters.

这些图像具有直观、形象、生动的特点，对学生了解地理事物的表象特征，掌握地理事物的空间分布规律，进而分析地理事物各要素之间的内在联系，起到文字所无法替代的作用，因此，对地理图像教学必须引起足够的重视。

Therefore in the teaching students should be made to actuallyfeel that spherical geometry knowledge can be used to solve or explainsome real problems in both life and production, to reach the relatedconclusions about spherical geometry by comparing it with Euclideangeometry, and to have anidea of some non-Euclidean geometry models aswell as differences between flat geomtry models and spherical geometry ones.

是为对数学有兴趣和希望进一步提高数学素养的学生而设置，重点是培养学生空间想像和几何直观能力，教学中应使学生切实地感受到利用球面上的几何知识可以解决生活或生产中的一些实际问题；让学生通过欧氏几何和球面几何的类比，得到球面上的几何的相关结论；使学生了解一些非欧几何模型，从而思考平面几何模型与球面上的几何等非欧几何模型的差异。

Measuring some turnery and grinding work pieces from the scene,we can get the good result that can explain this measuring diameter instrument has low price.And its measure method is simple,numerical value intuitional and accurate.Under the available school condition,it can self control,process,adju...

其实验效果良好，并说明，仪器价值低，测量方法简便，数值直观而准确，可以利用学校现有条件，自制加工调试和应用，从而改进了以前的测量手段和方法，提高了测量精度和实验教学的质量。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
