氮添加对白羊草土壤水溶性碳氮及其光谱特征的影响

, 2017
大气氮沉降对土壤的影响已成为近年来的研究热点，为了解氮沉降对黄土高原典型草原土壤质量的影响，以 白羊草群落为研究对象，以氮添加的方式模拟氮沉降，选取３个氮添加梯度，分别为Ｎ１（２．５ｇ／ｍ２），Ｎ２（５ｇ／ｍ２）和Ｎ３ （１０ｇ／ｍ２），并选取裸地（ＢＬ）和不施氮（ＣＫ）作为对照处理，分析了对土壤水溶性碳、氮组分及其光谱学特征的影响。 结果表明，氮添加降低了ＷＳＯＣ／ＴＯＣ和ＷＳＯＣ含量，随着氮添加水平增加均呈降低趋势；而对水溶性氮素组分影响 较弱，仅在Ｎ２ 中ＷＳＮ和ＷＳＯＮ显著降低，对ＷＳ－ＮＨ ...

氮化钛涂层对牙科铸造合金腐蚀性能的影响

Zhongshan Daxue xuebao. Yixue kexue ban, 2004
【目的】研究氮化钛涂层对牙科铸造合金腐蚀性能的影响。【方法】两种义齿常用的Ni-Cr合金、Co-Cr合金经常规包埋铸造成Ni-Cr、Co-Cr合金铸件,模拟临床打磨抛光形成20mm×20mm×1mm规格的试件。随机选择Ni-Cr、Co-Cr合金试件各6个,采用多弧离子镀法分别在其表面上沉积一层厚为2.5μm的氮化钛涂层(TiN)形成TiN/Ni-Cr、TiN/Co-Cr复合体。将Ni-Cr、Co-Cr合金、TiN/Ni-Cr、TiN/Co-Cr4组各6个样品分别置于人工唾液24h后 ...
