Mongolian Women

Women of China 1997年第2期 14-15页

作者： SHEN yantai li JIANGSHU

On 1 May 1947, Inner Mongolia Autonomous Region was founded in a Mongolian-populated settlement and became the first autonomous region for minorities in China. The Hulun Buir Plains is the largest grassland area in China. The Mongolian ethnicity, with a population of more than 4.8 million, has its own language and written script. In 1206, Tiemujin, chieftain of the Mongol tribe, established the state of Mongol and was proclaimed the Great Khan, with the reigning title of Genghis Khan.

Marine Science Bulletin 1999年第2期1卷 76-83页

作者： Ji ling, Ren Rongzhu, liang Yuangao and li Zheng (yantai Ocean Administration Office, SOA)

Detailed analyses of the monitored data provided by the yantai Ocean Administration Office between 1989 and 1996 show that, the fluctuation regularities of content of the inorganic phosphorus are as follows: the content of inorganic phosphorus fluctuated near the class-1 standard line basically from 1989 to 1993, tended to increase rapidly from 1993, and increased continuously, causing water quality to be deteriorated from the class-2 to class-3 standard by 19%. Causes for increment of the content of inorganic phosphorus are also analyzed. The results show that, the flux of phosphorus entering yantai nearshore sea area increases at an annual rate of 16.5 percent, in which the increment rates of the phosphorus contained in washing powder and in phosphate fertilizer are 12.9 and 17.5 percent respectively. Both of them kept a positive interrelationship with their fluxes into the sea. In addition, the migration and regeneration mechanism of the phosphorus within the nearshore area also lead to the

激光针灸治疗慢性结肠炎61例临床总结

针刺研究 1987年第3期12卷 180-181页

作者：张士林尤士征李世瑞烟台山医院烟台市芝罘区医学科学研究所

慢性结肠炎是一种原因不明的消化系疾病,在治疗上无特效药物,病情反复发作,患者苦不能言。因此,寻找或筛选有效的治疗方法实属重要,我们于1985年8月～1986年7月采用激光针灸治疗61例,取得较好的疗效。

The high content of aluminum(Al)impurity in the recycled cathode powder seriously affects the extraction efficiency of Nickel,Cobalt,Manganese,and lithium resources and the actual commercial value of recycled materials,so Al removal is crucially important to conform to the industrial standard of spent li-ion battery cathode *** this work,we systematically investigated the leaching process and optimum conditions associated with Al removal from the cathode powder materials collected in a wet cathode-powder peeling and recycling production line of spent li-ion batteries(liBs).Moreover,we specifically studied the leaching of fluorine(F)synergistically happened along with the removal process of Al,which was not concerned about in other studies,but one of the key factors affecting pollution prevention in the recovery *** mechanism of the whole process including the leaching of Al and F from the cathode powder was indicated by using NMR,FTIR,and XPS,and a defluoridation process was preliminarily investigated in this *** leaching kinetics of Al could be successfully described by the shrinking core model,controlled by the diffusion process and the activation energy was 11.14 kJ/***,the leaching of F was attributed to the dissolution of liPF6and decomposition of PVDF,and the kinetics associated was described by Avrami *** interaction of Al and F is advantageous to realize the defluoridation to some *** is expected that our investigation will provide theoretical support for the large-scale recycling of spent liBs.
