Analyses of the Self-Reversal Lines of the Prominence of 1984 February 18 1984年2月18日太阳边缘日珥自反变谱线分析
Study on Stray Light in Self-Reversal Background Correction for Atomic Absorption Spectrometry& The Properties of Stray Light and Its Influence on Background Correction 原子吸收自吸背景校正中杂散光的研究Ⅰ&杂散光的性质及其对背景校正性能的影响
The lead of feed grade manganese sulfate was measured by atomic absorption spectrometry ( AAS)-self-reversal deducting background. 用原子吸收光谱法(AAS)&自吸扣背景测定饲料级硫酸锰中的铅。
Moisture and vegetation in semi-arid area are fairly better than that in arid area. If human disturbance were eliminated, desertification would have self-reversal possibility, but the reversal would have repeatability. 在半干旱地区,水分、植被较干旱地区稍好,如果消除人为干扰,有自我逆转的可能,但具有反复性。
