The adrenal gland tissues were dissected into serial paraffin sections at the thick- ness of 3 μm. After HE and Masson staining, they were observed and photographed by the light microscope and Image-Pro Plus 6.0. The results show that zebra adrenal capsule is covered with thick connective tissue, which is about 230 μm. A large number of nerves and blood vessels are distributed in the capsule. The area of cortex is about 5 times larger than medullae. Zona glomerulosa is thin, about 300？m. The cells were arranged as column and ball. Zona fasciculata with the thickness of 1 750 μm is 6 times as thick as zona glomerulosa. The cells were ar- ranged in cord. Zona reticular with the thickness of 250 wm was closely adjacent to medulla and formed a jagged boundary. The medulla with the area of 4 mm2 was deeply dyed. It was concluded that some sympathetic ganglion cells were found in the medulla arranged in groups and surrounded with zona reticular cells but lots of the cells were found in zona reticular. Some connective tissue with chromaffin cells was found in the medulla center vein. The purpose of the present study provides reliable evidences for further study on morphology, physiology and pathology of the zebra.展开更多
传统的Na/金属氯化物电池(ZEBRA)由于使用了氯铝酸钠(Na Al Cl4)作为阴极电解质(熔点157℃),往往在较高温度(270~350℃)下才能运行。本文通过把三氟甲磺酸钠(Na CF3SO3)溶于1-乙基-3-甲基咪唑双三氟甲磺酰亚胺盐(EMIMTFSI)离子液体中,配...传统的Na/金属氯化物电池(ZEBRA)由于使用了氯铝酸钠(Na Al Cl4)作为阴极电解质(熔点157℃),往往在较高温度(270~350℃)下才能运行。本文通过把三氟甲磺酸钠(Na CF3SO3)溶于1-乙基-3-甲基咪唑双三氟甲磺酰亚胺盐(EMIMTFSI)离子液体中,配制0.2 mol/L的Na CF3SO3离子液体电解质。使用循环伏安法、热分析法分别测试离子液体电解质的电化学窗口、热稳定性。最后,以Na Cl包覆的泡沫铜作为电池正极,用玻璃封接的方法组装平板化的试验用Na/CuCl_2电池,并测试电池性能。实验结果表明:用离子液体电解质来替代传统的NaAlCl_4电解质有着很高的可行性与研究价值,组装的平板Na/CuCl_2电池可在175℃条件下稳定运行,表现出较好的电化学性能。展开更多
