Finally we got the main indices of eutrophication of lakes fleetly and exactly by analyzing the measured concentration of lakes in their algae breeding peak time.
并以我国湖库在藻类繁殖高峰期实测浓度数据为例，快速、准确地得出湖库富营养化的主要指标。
2
The value of lacunarity indices is in direct proportion to the degree of sand dune concentration.
结果表明，沙丘的分布形式越集中，沙丘的间隙度指数越大；
3
Better separation indices can be obtained by singular gravity concentration or flotation method and both of combination flowsheet, and gets effectively rid of carbon.
