以石墨、炭黑、碳化硅等三种含碳材料和碱度分别为0.8、1.0和1.2的基渣为原料，研究了炭黑、石墨和SiC加入形式(单独或复合，包括复合时的比例)和加入量以及基渣的碱度等因素对保护渣熔化速度的影响，并对试验数据进行了多元线性回归分析。

Microstructure analysis showed that graphitization degree of Ti-doped graphite increased and the correlation between graphitization degree and dopant quantity is complex.

微观结构分析表明，材料的石墨化程度大大提高，同时，材料的石墨化程度与其导热性能间呈现出较为复杂的关系。

After hybridization of two DNA probes with target DNA, EDTA-〓 and β-diketone come close to each other, and an EDTA-〓-β-diketonate ternary complex having strong and long-lived fluorescence was formed, thus the target DNA was detected sensitively with a detection limit of 6 pM (0.6 fmol per assay) by time-resolved mode.

系统研究了使用EDTA-〓为标记物的石墨炉原子吸收光谱免疫分析法，并将之用于人血清中AFP和水中BSM的测定。该法中使用了EDTA-〓标记SA及生物素标记抗体或抗原，在96孔板中的免疫反应结束后，利用稀硝酸将反应产物分解，然后用石墨炉原子吸收光谱法对免疫反应产物进行测定。

Retention of cations such as quats on Hypercarb is dueto the interaction with the electron cloud on the graphite; also,these are flat molecules which can align themselves closely to thesurface
