将水库防洪调度方法划分为两大类：一类不考虑预报，通常是选择"坝前库水位或实际入库流量"作为遭遇洪水量级及改变泄量的判断指标，称为常规防洪调度方法；另一类考虑预报，选择的判断指标多是产流预报的"累积净雨量"或汇流预报的"洪峰流量"或短时"晴雨"预报等信息，简称防洪预报调度方法。

Borrowing ideals from the experience of American research universities while integrating it to the current concrete situation of Chinese research universities, this study arrival at a conclusion that on the competitiveness development and their selection of strategies Chinese research universities should put close attention to two aspects as followed: firstly, research universities\' competitiveness should get off along the road of intensiveness, catch three factors like resource, culture and capability, adopt appropriate selection of strategies to promote their competitiveness.

借鉴美国研究型大学的经验，结合当前我国研究型大学的具体情况，本研究提出我国研究型大学在竞争力发展及其策略选择中应关注的两个主要内容：一是研究型大学竞争力应走内涵发展的道路，注重资源、文化、能力建设，通过适当的策略选择来提升自己的竞争力。
