原子吸收光谱的几个英文题

1.A hollow cathode lamp produces light emission that is characteristic of the atomic species in the lamp. Atomic absorption and emission linewidths are inherently narrow.

2.Atomic absorption spectroscopy requires gas-phase atoms in their ground state. Excitation and ionization of the analyte does occur in high-temperature flames, and reduces the amount of absorption from the analyte atoms.

3.Since molecules have broad absorption bands, they can interfere by absorbing at the wavelength of the element being analyzed.

4.Since the sample is loaded directly into the furnace, none is lost in nebulizing as in a flame AA.

小弟不才.答案是:B B D A .第一题问HCL灯是窄带光源. 第二题是 AAS火焰的作用.偶不知道C和D 的意思,呵呵 .第三题是问灰化的目的.第4题是问石墨炉的优点,偶选了A.不知道是不是对的,请大虾指点啊~~~
