In the first, the background of this dissertation, the he status which helicopter blade dynamic balance experimental platform system design and using are introduced, helicopter blade dynamic balance experimental platform system is not designed in our country, so in this Dissertation, the advanced experience is accepted and some innovative methods also are used in the system design.

此论文通过借鉴国内外对直升机旋翼动平衡试验台系统设计的经验，确定采用当今较新与较成熟的技术构建了集数据采集与控制为一体的试验控制系统来满足整个动平衡试验的要求。另外还对直升机旋翼动平衡试验台系统方案设计中各分系统作了简单介绍，并通过和以往系统比较分析，在借鉴前人经验的基础上进行了创新。此论文主要介绍了直升机旋翼共锥度测量分系统的设计与实现。

Combined chaos theory with Neural network, it presents predisposal technology in data-disposal of phase space, compares it with others, its convergent speed and forecasting precision have been improved greatly.

将混沌理论与神经元网络结合起来，首次提出了在相空间中进行数据预处理的神经网络训练样本预处理技术，该技术通过与其他预处理技术的比较，其网络收敛速度与预测精度有较大提高。

In this paper the phase shifts in spiral galaxies M 81 and M 51 has been computed. It is found that the theoretical patterns of the spiral arms agree in general with the observational results of 21 cm radio emission in the main.

本文具体计算了M81，M51两星系的恒星臂与气体臂之间的相移，给出了两星系的星臂乃气臂的式样，与21厘米射电观测结果比较表明，理论与观测基本上是符合的。

Secondly, relations between the structuralism and physics teaching illustrate that the physics history can play the role of "advanced organizer" in improving the transfer ability. Moreover, the theory of recapitulation of physics announces the inherent similarity between the process of physics research and the process of physics conception learning. According to constructivist learning theories, the dissertation explains the process of students' learning the scientific concepts.

首先论文通过分析比较皮亚杰认知发展论和库恩科学发展论得出教育实践应与科学发展规律保持一致，应重视物理学史在物理教学中的应用，对于不同认知水平的学生和不同类型的知识应采用不同的教学方法：其次从结构主义与物理教学的关系说明物理学史在提高迁移能力上可以扮演"先行组织者"的角色；再次，通过物理文化重演理论揭示人类研究物理学的过程与学生学习物理概念的过程的内在相似性，并根据建构主义学习理论解释学生学习科学概念的过程。

The sum of BCOD of BODst test and XH measured through batch respirometer is consistent with the BCOD of BODlt test and the ratio between them was in the range of 0.88-1.02 with average 0.94. The BODlt test is time-consuming and the microorganisms'population and their metabolic characteristic are different from that of the actual activated sludge process. So the respirometry has the advantage of time-validity and representation for the actual activated sludge system.

6呼吸测量法测得的BCOD明显小于长期BOD测试方法的结果，这是由于后者得到的BCOD包括所有的活性微生物COD组分；短期BOD测试得到的BCOD与异养菌COD之和与长期BOD测试得到的BCOD比较接近，两者之比在0.88-1.02之间，平均值为0.94；长期BOD测试耗时长，测试用的微生物种群及其代谢类型都与实际活性污泥过程明显不同，因此，从测试结果的时效性和代表性方法考虑，短期BOD测试更具优势。

In this project, ruminative, compared with the reference method and the theory and practice of the method, from the Public Trust of the core semantic start, a detailed analysis of the Public Trust of the government concept, meaning, the Public Trust of the government evaluation criteria and the Public Trust of the government role and status stressed the governments Public Trust is the order of the socialist market economy is based on the basic social governance, and the social stability is a prerequisite for development .

本文采用思辨的方法，比较与借鉴的方法以及理论与实际相结合的方法，第一部分从公信力的核心语义入手，具体分析了政府公信力的概念、内涵、政府公信力的评价标准以及政府公信力的作用和地位，强调了政府公信力是社会主义市场经济秩序的基础，是政府治理社会的基本要求，是社会稳定与发展的前提条件。

The results show that, during the period of collision between the sand grain and the sand bed, the lost kinetic energy is more than half of the total energy. Moreover, because the percentage of collision angles with more than 0° is up to 70％, the vertical speed of sand increases even if the kinetic energy decreases, which ensures that the sand particles can receive more energy from the air to keep on the saltation movement.

实验结果表明，沙粒与沙床碰撞过程中损失的动能超过总能量的一半，且由于碰撞平面角大于0°的比例达到70％，即使沙粒在碰撞过程中能量有所损失，沙粒与沙床碰撞后垂直分速度增加的现象仍比较普遍，使得沙粒在与气流相互作用的过程中获取更多的能量，从而为沙粒的持续跃移提供了保证。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.
