The national broadcast and tv universities are making efforts to advance the development of pilot project study , explore the mode reform of personnel training , and enforce the quality mind . the sustainable development of education has been realized , and the social benefit is available 全国广播电视大学系统全力推进试点研究，探索人才培养模式改革，强化质量意识，实现了电大教育事业的可持续发展，取得了令人瞩目的社会效益，但也必须清醒地看到，由于种种原因，试点项目工作在许多方面尚不尽人意。
When catchment area , average channel gradient and catchment shape factor of designed culvert or bridge are known , a user can be convenient to get local parameters c , e and b from standard contour charts and easy to calculate flood flow just by a calculator . design period of flood flow is enormously shortened as well as a high precision . estimated flood flow through culvert or small bridge by new calculation model is generally less than by traditional methods , so that much cost is cut down a s reducing the span of culvert or small bridge 以75000km ~ 2的川中丘陵地区为试点研究区，绘制了该地区新模型的参数等值线图，率定了不同设计频率的改正系数，使设计者只需在地形图上获取集水面积，河道平均坡降和流域形状系数，在参数等值线图上查得桥涵所在地的相应参数，使用计算器即可迅速计算出设计流量，大大缩短了设计周期，且精度较高，设计的洪水流量一般低于传统方法，从而可减小桥涵跨径，节省投资。
The approaches of environmental education include : education about the environment , education in the environment , and education for environment . these approaches contribute reflect the difference goal of environmental education . usually , curricula are focus of school environmental education by which to infiltrate to multi - disciplinary 所以本研究旨在通过试点研究，尝试引入iso14001环境管理体系这一高度结构化的系统工具，改造现有的学校环境教育，发展一套适合学校的基于环境管理体系的全校性环境教育模式。
