柽柳科红砂属(Reaumuria L.)的分类与分布/Classification and Distribution of the Genus Reaumuria L.in Tamaricaceae[J]

, 2014
柽柳科红砂属植物种类在我国的分布虽然不多,但属的种类可形成亚洲干旱区荒漠地带的建群种或优势种.目前尚无分类专著和系统的分类研究.根据世界各地植物志和国内标本馆信息,对世界红砂属的分类和分布进行了系统的整理.确认红砂属含21种,隶属2亚属2组6系,我国仅4种.该属是中亚干旱区集中分布的一个属,有18种之多,但也延伸到西亚、南欧、北非等地.在亚属、组、系的分类等级上,对其分布进行了分布点图的标记 ...

液体分布器出流均匀度评价方法研究

Gongye shui chuli
液体分布器的出流均匀性是影响高效污水处理工艺的关键指标，当前对于其出流均匀度的评价方法还没有统一的标准，尤其是对于对称结构液体分布器的出流均匀性尚难以评价。针对两级液体分布器结构，建立了基于组分输运模型的简化有限元分析方法，并验证了该分析方法的适用性，研究了不同进液方式和不同尺寸液体分布器出流流量分布情况，并选用合适的出流均匀度评价方法进行评价。结果表明：两端进液和中间进液结构液体分布器的出流均匀性要明显优于一端进液结构，而两端进液结构的出流均匀度又要略优于中间进液结构 ...
