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。

Objective: This experimental study is based on earlier animal and clinical experiment, drawn thinkings of combinations with two methods and pursued a synthesis method of high-efficiency, cheap and convenient calcium and exercise treatment. We adopt taking natural-clam's casing powder and preconcereted-intensity excises to intervene shape of osteoporosis in gelded rats, than we compare the indexes such as the biomechanics indexes of the right femur and the third lumbar vertebrae, the weight and uterus quotiety of rats before the experiment to these indexes after the experiment. We hope to find better and suitable way to prevent and treat the postmenopausal osteoporosis and offer reference for clinic.

目的 本实验的主要目的是在前期动物实验的基础上，引入两种方式联合干预的思维，立足于探求既高效又经济、方便的补钙剂加上与运动疗法相联合的方式，对切除雌性大鼠卵巢而复制成的骨质疏松症模型进行服用天然贝类蛤蜊壳粉，同时施以预定强度的运动刺激的方法，再通过试验前后大鼠体重、子宫指数的变化及大鼠股骨和椎体生物力学指标的对比变化进行分析，以期探索出防治绝经后骨质疏松症的更好的、更适宜于大众的手段；并为天然钙剂和运动联合作用防治PMOP提供参考。

The main content included in the paper is as follows: The European identification methods of type of wave load is introduced and compared with the methods in Code of Hydrology for Sea Harbour. In order to reveal their difference, they are tested by the experiment data. The relation between phase and frequency are analysed through the Hilbert and wavelet transformations. And a new method of identifying the breaking wave load is set up based on the linear relation between wave height and wave press before the breakwaters. The probability distribution is tested by the statistic of experiment data. Based on the experiment data, the paper analysed the influence of reflection coefficient according to different factors, and its property is got. The work property of charmfered breakwater under breaking waves is analysed. Through the statisticof its wave press and wave force the distribution of press on the breakwater front face and its reducing effect to breaking wave force are proved.
