Atomic absorption spectroscopy was used to determine the dezincification coefficient of 70/ 30 brass subjected to slow-strain rate stress corrosion tests in 1 normal aqueous sodium nitrite solution over the potential range from-0.1~+ 0.1V ( SCE). 用原子吸收光谱测定了在慢应变速率的应力腐蚀试验条件下,70/30黄铜在1当量亚硝酸钠水溶液中,电位范围&0.1~+0.1V(SCE)内的脱锌系数。
Bi with a higher atomic number than iodine is expected to have a higher X-ray absorption coefficient than iodine, and could theoretically cause greater contrast enhancement in CT imaging. 铋元素具有比碘更高的原子序数,导致了它具有更高的x-射线衰减系数,在理论上能提高CT成像的对比度。
