The main results can beexpressed as follows:(1)Based on πtheory, some affected factors about wave forces are given, and therelation between affected factors and wave forces is analysised by experimentalresults.(2) The distribution of wave press at representative time and reflection nature aregiven and their variety charactes are discussed by experimental results.(3)By comparing the wave forces of quarter-circular breakwater and semi-circularbreakwater under the same wave conditions,some approximately wave forcesexpressions of quarter-circular breakwater are given.(4)Based on VOF method to trace water free surface,solve numerical value ofRANS equation,and get the distributions of flow field and wave press ofquarter-circular breakwater at the same time during one period,the mechanism ofwave force is also discussed elementarily.(5) Based on the result that RANS equation of numerical simulation agree wellwith experimental results,a new approach to study hydraulic natures of quarter-circular breakwater is provided.

其主要结论如下：一、通过π定理，确定影响波浪力的无因次参变量，根据试验结果对其影响因素进行分析；二、基于模型试验，给出典型时刻圆弧面防波堤的同步波压分布和反射特性，讨论它们的变化特点；三、通过相同条件下圆弧面防波堤与半圆型防波堤两种堤型试验波浪力的比较，给出了圆弧面防波堤波浪力的近似方法；四、利用VOF法追踪自由水面，数值求解RANS方程，得到圆弧堤堤体周围的流场和压力场，初步分析了速度涡流与压力场的相互影响；五、对比数值分析与试验结果，探讨数值方法研究圆弧面防波堤水力特性的可行性，提供新的研究途径

By contrast with the experimental data, the results obtained from numerically simulating are in good agreement with experimental data.

模拟结果表明，数值模拟结果和实验结果有较好的一致性。

While the experimental side force distribution over a slender body with a blunt ogive nose is basically consistent with the curve of the analogy predicted, and the characteristic points and half cycle of the experimental curve are basically constant with the roll angle changing 360°. But the local maximums in the curve are not the results as the analogy predicted, which is an important flow feature of 3-D slender body than that of 2-D cylinder.

而钝头拱形细长体在大迎角下的截面侧向力分布与脉冲起动横流比拟方法预测的侧向力曲线的形状是基本相同的，而且随着滚转角旋转360°，截面侧向力分布曲线的特征点和半周期基本保持不变，即它们都基本上不受滚转角变化的影响；但是截面侧向力分布曲线极值点形成的原因却是不同的，这是细长体绕流区别于二维圆柱绕流的一个重要特性。

At the same time, 9 groups data are conversely choosed according to uniform orthogonal array from 71 groups observed data of suspended grid plunge pool, the mold is set up by the method of PPR, the surplus 62 groups data are used to proceed examination, the empirical type optimum design of experiments are proceeded inversely, all of these confirm that a lot of model experimental results can be replaced by a few of test times under nonstrict uniform experimental condition. The result can provide the feasibility reference basis for same kind of model design of experiments in future.

同时从71组悬栅消力池观测数据中，按均匀正交表反选9组数据，用PPR方法建模，剩余的62组数据进行检验，逆向进行了实证性优化试验设计，证实了即使在非严格的均匀试验条件下，仍然可以用少量的试验次数替代大量的模型试验结果，为今后同类模型试验设计提供可行性的参考依据。

To some degree, this study revealed the relationship between ossein and bone miner and the important preventive and therapeutic effects of ossein on OP. It provides theoretical and experimental basis for the research and development of effective prescriptions to cure OP. Limited by the actual experimental situation, we only did some study on the synthesis and content of type Ⅰ collagen. Further study on the changes of decomposition and structure of type Ⅰ collagen are needed to be done.

本课题的研究，在一定程度上揭示了骨胶原纤维和矿物质之间互根互用的辨证关系，及Ⅰ型胶原在骨质疏松症的发病和治疗中所起的重要作用，并为开发研制治疗本病的有效中药复方提供了理论和实验依据，但由于条件所限，本研究仅就Ⅰ型胶原的合成及其含量变化做了初步观察，而本病中骨胶原纤维的分解代谢及其结构的改变，尚待进一步探讨。

It can been used to evaluating of the experimental teaching. The national education departments criterion of curriculum is our gist. Base on it, concrete, measure and outer have been done. In this article, the six guideline of summative evaluation, experimental evaluation recording tables have been given.

教育部颁布的"高中物理课程标准"是实验评价的依据，在此基础上，将它具体化、变为外在的可测的指标，建立了中学物理实验终结性评价应达到的六项指标，本文给出了实验操作评价记录表和示例，试图提出了实验操作评价的实施原则。

METHODS Isolated rat lungs were used as the oxygenator. Venous blood from experimental rats was oxygenated in isolated lungs and then was perfused into the aorta of experimental rats by pump.
