The phases of sulfuric acid slag of various sizes were drawn by seven - step method in the improved separation condition of disturber , and phases of thallium were compared before and after the slag was grinned to analyze phase migration 为了进一步探讨颗粒物中铊相态提取的技术和方法，在优化干扰物分离条件下，采用七步法提取了几种不同粒径硫酸废渣中铊的相态，比较了废渣研磨前、后各相态铊的异同。
Clinical manifestations include atypical chest pain , an abnormal resting ekg , a positive treadmill test , sustained ventricular tachycardia , bundle branch blockage , paroxysmal atrioventricular block , reversible perfusion defect noted on thallium scan , etc 临床表徵包括非型胸痛、异常心电图变化、跑步机式验阳性、持续性心室频脉、吏传导阻滞、阵发性房室阻断、铊-心肌扫描可见可逆性心肌灌流不足等等。
There is considerable interest in the effects of all types of radiation on health , including medical radiation such as from diagnostic imaging such as x - rays and thallium scans , waste from nuclear power plants , weapons testing fallout , industrial radiography for pipelines and tanks 最近许多人关注到各类辐射对人体健康所造成的影响，包括求医时接触的辐射即光和铊扫描核电厂废料武器测试的微尘工业用光?照相术等。
Metal halide gas - discharge lamps possess the advantages of small sige , high luminous efficiency , long life good start quality , simply appending power supply . they are widely use in movie projectors and overhead projectors etc . the metal - halide gas - discharge lamps include metal halide lamps with dysposium iodide , mercury lamps metal halide lamps with scandium - sodium iodides and metal halide lamps with sodium - thal - lium - indium etc 金属卤化物放电灯具有体积小、发光效率高、使用寿命长、启动性能好附加电源较为简单等优点,一般用于电影放映机、投影仪等仪器,品种有金卤灯（汞灯） 、镝灯、钪钠灯、钠铊灯等
