1) particulate nitrogen
颗粒氮
1.
Based on the analysis of particulate organic carbon(POC) and particulate nitrogen(PN) of the 155 samples collected from the 41 stations in the Bohai Bay and its adjacent sea,during the summer period in 2006,combining with the data of environmental hydrology,the spatial distributions,influential factors and source of POC and PN were discussed.
根据2006年8月在渤海湾及其邻近海域41个站位取得的155个样品的颗粒有机碳(POC)和颗粒氮(PN)的分析数据,结合同步获得的水文环境要素资料,分析了该区夏季POC和PN的空间分布特征、影响因子与有机碳物源。
2) Si 3N 4 particle
氮化硅颗粒
1.
The addition of Si 3N 4 particles to carbon fiber reinforced silica composite increases the mechanical properties, but decreases the thermal properties of the composite because of the precipitation of tridymite.
在碳—石英复合材料中加入氮化硅颗粒可提高其力学性能,但少量鳞石英的析出使材料的热学性能恶化。
3) soil particulate organic matter-nitrogen
土壤颗粒氮
1.
The results showed that the ratio of soil particulate fractions, soil particulate organic matter-nitrogen(PON) ratio, nitrogen content of soil particulate fractions, soil PON content did not significantly change with the altitude.
结果表明:土壤颗粒组分比例、土壤颗粒氮比例、土壤颗粒氮含量和土壤颗粒组分氮含量都随海拔升高而差异不显著;就土壤颗粒组分比例而言,0~15cm土层在阳坡3800m处、阴坡3000、3200和3500m处较高,15~35cm土层在阴坡3200和3500m、半阴坡2800m处较高(p<0。
4) particulate phosphorus and nitrogen
颗粒态氮磷
5) particulate organic nitroge
颗粒有机氮
6) boron nitride ceramic particles
氮化硼陶瓷颗粒
