A Native Platinum Deposit First Discovered in Shimian County, Sichuan 四川石棉县首次发现独特的自然铂矿床
The trace element Rh exists mainly in native platinum, platinum-iron alloy and Pt-containing osmiridium. 主要矿物是自然铂矿、铁铂合金、钌铱锇矿、等轴锇铱矿和铱锇矿。
Methods The native electrochemical instrument and the platinum duct electrode combined with the membranous Ni-Ti memorized alloy stent was used to kill the tumer cells, expand the structured area and hence relieve the obstruction of the advanced esophageal and cardiac carcinoma. 方法采用国产电化学治疗仪和铂金导管状电极与带膜镍钛合金支架相结合,杀灭肿瘤细胞、扩展狭窄管腔,解决晚期食管、贲门癌梗阻。
