Based on the single-axis air-bearing test bed, three experiment schemes are creatively designed for investigating the behaviors of rigid-flexible coupling dynamics:(1) experiment scheme for structural dynamics problem under a non-inertial frame,(2) experiment scheme for rigid-flexible coupling dynamics with unknown large overall motions,(3) experiment scheme for modal analysis of a typical rigid-flexible coupling system.

为了能更深入地揭示刚柔耦合动力学特性与验证本文提出的一次近似模型的正确性，最后重点介绍了我们在单轴气浮台动力学仿真实验平台基础上，经过多次探索和总结，创造性地设计的三套刚柔耦合动力学实验方案：(1)非惯性系下结构动力学问题的实验研究方案，(2)大范围运动为自由的刚柔耦合动力学问题的实验研究方案，(3)刚柔耦合系统模态分析实验方案。这三套方案从实验的角度来讲是可行的，这为下一步的实验工作打下了基础。

At last, all related problems due to ship type and towing speed influencing the quality of captured images and results were discussed. A ship model with V-shape bottom and protruding keel might cause some disadvantages for PIV measurements. The use of longer laser light ducts extending deeper is a possible solution. A ship model with light yellow paint will cause the unproportionate of light and will cause white background on captured images. It is suggested to re-paint the ship model in black or dark colors to solve this problem. In high-speed test conditions, a ship model's bow waves entrain large amount of air bubbles into water and those bubbles will block the view of camera causing some random black spots in the images. Thus, it is necessary to remove the useless black spot data and repeat the same test condition if statistics requires enough number of images.

本文讨论建立此系统之技术及实验方法，设备的架置方式和配置为一可调性调整之开放式架构，质点施放方法以一自制的施放架於实验前先布置於测试段中，并制定一实验流程规范，再分别针对实验所得滑航型及排水量型船模的流线方向及切流线方向各不同位置及船速之速度进行流场分析；实验结果发现不同船型会造成不同的实验困难：船形上突起之龙骨及V形船底会遮住照明光线，可利用较深之导管调整光页角度改善；而浅色船模表面会造成光线的不均匀，可以更改船模涂装颜色改善；高速实验的气泡会不定点的遮住光线，须先除去无资料区域并使用更多资料组数来改善。

Situation of the utilization of experiment resources:(1) The opening up of the laboratory are relatively weak aspect, so, in these schools, students have few chances to do extra-curricular experiments;(2)Almost all of schools teaching experiment instruments are used, less instrument is not used, the main reason for not used is that these experiment instruments are irrelevant with materials or they are obsolete and damaged;(3) Teachers always experimentalize according to the teaching materials step-by-step, there is no improvement;(4) Most teachers don\'t pay attention to the evaluation of experiment result, students merely write expriment report;(5) The teachers have realized some significance of inquiry experiments, but have not begun action consciously.

从实验教学过程和实验资源开发利用情况看：(1)实验室的开放是比较薄弱的环节，绝大多数学校只有上实验课时才开放实验室，因此这些学校的学生进行课外实验和小制作的机会很少；(2)绝大多数学校实验教学仪器的利用情况较好，闲置仪器较少，其闲置的原因主要是实验内容与教材无关或仪器陈旧损坏；(3)实验过程基本上是按教材提供的步骤进行，教师对实验过程和教学仪器的研究和改进较少；(4)很多教师不重视对实验结果的评价，学生很少写实验报告；(5)教师对探究性实验的意义已有认识，但还没形成自觉行动。

Ground on the actual conditions of CAI, CSE and physical experiment teaching in our country, a new-style simulant physical experiment-teaching mode that based on independent instruments and components is offered in this paper. This mode is devised according to the essential CAI educational theory-the Constructivism also. The most distinct advantage of this mode is, with enough simulant instruments and components, students can not only implement experiments according to the textbooks, but also design and carry out new experiments by themselves. Students experiment interest can be activized and their creative thinking and competence can be improved.

本文在分析了我国计算机辅助教学、计算机仿真实验和物理实验教学现状的基础上，根据计算机辅助教学的基本教育理论-建构主义，提出了一种全新的仿真物理实验开发模式-基于仪器和元器件的开发模式，指出了其最突出的特点，即在提供充足的实验仪器和元器件的基础上，学生不仅可以按照教材上的实验方案，也可以自己设计实验方案进行实验，甚至还可以自己设计并实施新实验，从而充分调动学生的学习兴趣，并由对仿真实验的兴趣过渡到对实物实验的兴趣，以弥补我国学生实验条件差、实践机会少的缺陷，培养他们的动手能力和创新能力。

Experimental results disclosed that the upper limit on the photon mass was 1.2×10-51g, and this figure, collected by Particle Data Group in 2004, has improved almost 20-fold compared with that of the static torsion balance experiment.

该数值不仅将国际上扭秤静态实验结果提高了约20倍，而且调制的实验方法还有效地克服了扭秤静态实验中实验结果对宇宙磁场矢势与地球自转轴之间夹角的依赖关系，并且极大地抑制了各种周日背景干扰的影响，提高实验的置信水平，该实验结果于2004年被国际粒子物理数据组收录。

Parallel interface achieve the data transmission between bit and I/O devices using more than one data wire, which is suit for short distance transmission. Come to a direct display of its functionalities with VC virtual platform by visual design.Data and code in every computer parts, describes itself by combination, the function is invisible.

然而，目前在计算机实验教学中，由于实验仪器复杂，精密和昂贵，往往不允许自行设计实验参数，反复调整仪器，这对剖析仪器性能和结构，理解实验的设计思想和方法是很不利的，在本次设计中主要应用了VC实验平台来进行仿真实验。
