The corrosion inhibition of brass by a low phosphonic copolymer in the artificial cooling water was investigated with weight loss measurements,energy-dispersion X-ray analysis(EDX) and electrochemical tests.

采用失重法、能量散射X-射线、电化学方法,研究了自制低磷共聚物在配制冷却水中对黄铜的缓蚀作用,分析了空白实验和加入低磷共聚物后黄铜试片的表面元素组成,探讨了低磷共聚物的缓蚀机理。

The ratios of Al 2O 3/SiO 2 and kaolinite+illite vs quartz for whole rock indicated the intensities of both chemical weathering and erosion.

研究结果表明 ,全岩的化学蚀变指数 (CIA)值主要代表自然作用下化学风化的强度 ;而硅铝率 (或Al2 O3 SiO2 比值 )和 (高岭石 +伊利石 ) 石英比值在全岩研究中代表化学风化与侵蚀作用的共同强度 ;Al2 O3 SiO2 比值与CIA值的相关关系可以作为区分化学风化作用自然因素变化与侵蚀作用加剧的一种新的分析方法 :当样品CIA值异常偏离趋势线时 ,反映出自然化学风化作用的异常变化 ,而Al2 O3 SiO2 比值的异常偏离则可能反映了表层侵蚀作用的加剧 ;结合当地自然环境和人类活动的特点 ,可以推断人为因素对表层红土剖面地球化学特征变异的干预和对侵蚀作用加剧的贡
