biomass size spectra生物量粒径谱
1.Biomass size spectra of benthic organisms(BBS) and normalized biomass size spectra(NBBS) were constructed for the first time in four stations in Huanghe River adjacent waters.首次建立了黄河口邻近海域4个站位底栖动物生物量粒径谱和标准化生物量粒径谱。
3)standard sedimentation diameter标准粒径
1.After that, The effect of grain size composition on the relationship between the diameter D L measured by settling tube method and that by standard sedimentation diameter D b for diffetent size gradations is studied in detail.０６ｍｍ的粒析级配组成机理，及级配组成不同对标准粒径Ｄｂ与粒析粒径ＤＬ关系的影响进行了详细研究。
4)size grade scale粒径标准
5)standard biochemical oxygen demand标准生物氧化需氧量
6)Microbiological standards微生物含量标准
