The educational technology has the very intense practical orientation, but because this practical orientation is too powerful, it causes the researchers of educational technology can be unable to stop to think some basic theory questions, and be far away from asking educational technology some ultimate questions about educational technology. So it has caused that afer semicentennial developing educational technology still exit some questions such as confusing, the reality helpless, deficient theory, although it has obtained many encouraging performance, but it is unsuitable that educational technology is the commanding point of education reform and the breach status. Facing these conditions, educational technology needs carry on reviewing and looking up in historical and reality multiple field, needs integrate and conclude for obtained studying results, needs reflect on own level, and need to have the big breakthrough in the discipline elementary theory construction.

教育技术具有非常强的实践价值取向，但这种实践取向的过于强大往往使得教育技术的研究者们无法停下来思考本领域一些基本的理论问题，因此直接导致了教育技术学在经历了半个多世纪的学科建设历程之后，尽管取得了诸多可喜的成绩，但是依旧存在理论与实践研究的诸多问题，这对于面临新技术的发展和世界范围的教育改革浪潮而给予的教育技术作为教育改革的制高点和突破口的地位是极不相称的，教育技术学迫切需要在历史与现实的多重视野中进行回顾与前瞻，对已经获得研究成果进行综合和归纳，需要对学科自身进行深层次反思。

By with meets the match team the shooting technology statistics to carry on the comparison, does the research the basic basis; Between the comparative analysis China women's basketball and the world outstanding women's basketball's shooting technological gap, and from now on will provide the reference for the correct understanding and the objective evaluation China women's basketball shooting technology using ability to our country women's basketball shooting technology's training and the fundamental research.

For the capacity of propeller turbine is often small, people pay little importance on the transformation of reducing capacity under specified conditions. So, nowadays little research mentioned above has been developed.For the particularity of the designed factors, the author has improved the traditional theory, and has fined an available Method of singular point distribution. At present, no one has developed CAD hydraulic design software of lower specific speed axial flow runner in our country.

由于设计条件的特殊性，在研究设计方法过程中，论文基于传统设计理论，对引用的一些基本规律做了一定改进，在具体设计过程中，对经验参数的选择方法做了一定探索，研究与探索运用奇点分布法设计低比转速轴流式转轮叶片；传统的设计工作全部由人工完成，无法满足当今社会科技生产发展的需要，因此论文开发了一套具有人机对话界面良好特点的低比转速轴流式转轮CAD软件。
