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。

2The papre decompounds the complex motion of the robot into two types of basic motions, that is self-discipline bionic worming and pose adjustment. Thus the arithmetics of the pose and orientation of the robot are unified, which provides advantage for mix control mode and simple kinematics analyse.

As the same section is concerned, near the bottom the maximum value of frequency appear within 1mm of bubble size, towards the water face this value tend to decrease, yet the corresponding size turns to increase; in the same time, the frequency is concentrated near the bottom and deconcentrated near the water face; under the experiment condition, the maximum frequency of the total section approximately appear at 0.5mm size; mean bubble size access 0 at bottom and increase acceleratively towards water face where tend to be infinite; total number increase during developing of aeration, and become steady when reach wholly developed area; on the same section, the total number in unit time tend to increase at first and decrease then, along the water depth.

对于同一断面，靠近槽底的测点气泡个数分布最大值出现在气泡尺寸小于1mm的范围内，朝水面方向各测点气泡个数分布最大值呈减小趋势，而其对应尺寸则呈现变大趋势；在靠近槽底，个数分布表现得比较集中，而在水面附近气泡个数分布曲线表现得低而平缓；实验条件下，整个断面上的气泡个数分布的最大值大体上出现在尺寸为0.5mm的地方；气泡平均尺寸在槽底处接近于0而朝水面方向迅速增大，且越接近掺气水流的水面，增加速度越快，最终趋于无穷大；气泡总数在掺气发展区内是沿程增加的，当掺气水流发展到一定程度后气泡总数就基本保持不变了；在同一断面上，各测点单位时间内的气泡总数随高度呈现出先增加后减小的趋势。
