Applying the Large-scale multi-configuration Dirac-Fock wave functions, we calculated the parameters such as wavelength, oscillator strengths and excited energy for the transitions related to lightning spectra. The most important effects of relativity, correlation, and relaxation are included in the computational model. Comparison of the calculated results with experimental spectra shows that the spectra in plateau area have a distinctive characteristic. Beside the lines of lower excited state with n=3 in NII ions, transitions of NI and OI are increased, their excited energy is around 13~14eV, and there are rarely lines from OII ion.

将原子结构的理论应用於闪电光谱的研究，用多组态Dirac-Fock方法，计算了有关光谱线的波长、振子强度以及相应的激发态能量等参数，理论与试验观测资料进行比较分析后发现，高原地区闪电首次回击光谱的结构及跃迁特性与其他地区有明显的区别，除NII离子n=3的低激发态产生的跃迁谱线外，激发能量为13~14eV左右的中性NI和OI的跃迁增多，但很难观测到OII离子的跃迁谱线。

The level of β-tp was in direct proportional to the proliferation of cell in the oligodendroglioma cell lines (SHG-44, U-251, BT-325), but not in the non-oligodendroglioma cell lines (oophroma, prostate-carcinoma and neuro-oocyte).

但在非胶质瘤细胞株，如卵巢癌细胞，神经母细胞瘤细胞及前列腺癌细胞株等，β-tp的浓度与细胞增殖的趋势相反。

objective to investigate the inhibition mechanism of nanoapatite on the human hepatocelluar carcinoma.methods stable and single-dispersed nanoapatite were synthesized with sol-gel method.nanoapatite were surveyed by zataplus and tem.their effect on the bel-7402human hepatoma cell lines was investigated by the mtt methods,and the mechanism was studied from changes in ultrastructure.results the result showed that inhibition of nanoapatite on the bel-7402human hepatocellular carcinoma cell lines was presended obviously in vitro.conclusion nanoapatite entered into cancer cytoplasm,and cancer cells result in oncosis.
