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.

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.

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.
