1The pulsed high magnetic field facility and scientific research at Wuhan National High Magnetic Field Center显示文摘Wuhan National High Magnetic Field Center(WHMFC)at Huazhong University of Science and Technology is one of the top-class research centers in the world,which can offer pulsed fields up to 90.6 T with different field waveforms for scientific research and has passed the final evaluation of the Chinese government in 2014.This paper will give a brief introduction of the facility and the development status of pulsed magnetic fields research at WHMFC.In addition,it will describe the application development of pulsed magnetic fields in both scientific and industrial research.Xiaotao Han Tao Peng Hongfa Ding Tonghai Ding Zengwei Zhu Zhengcai Xia Junfeng Wang Junbo Han Zhongwen Ouyang Zhenxing Wang Yibo Han Houxiu Xiao Quanliang Cao Yiliang Lv Yuan Pan Liang Li 2017Matter and Radiation at Extremes2017,2,6:5

3Effects of fluoride on growth and reproduction of the army worm, Mythimna separata (Walker)显示文摘This paper deals with effects of airborne fluorine on the army worm, Mythimna separata (Walker), by rearing the larvae on the wheat foliage exposed to HF or fumigating the larvae on the artificial diet with the pollutant. Larval relative growth rate (GR) and index of population trend of the insect reduced by 5% and 11%, respectively, when the larvae were reared on the foliage taken from the wheat plants exposed to 0.87 g·dm-2·day-1 of fluorine compared with those of the control. An extra instar appeared in a majority of the larvae treated. Survival rate and GR of the larvae on the wheat plant being exposure to the same concentration of fluorine in field open-top fumigation device were 40% and 15% lower than that of the control, respectively. Similar experiment with the insect on the artificial diet also showed that direct impact of the pollutant on the army worm was greater than its indirect effect via their host plant.Gong Peiyu, Li Xiuzhen, Wu Kunjun Shu Jianmin and Cao Hongfa Institute of Zookogy,Academia Sinica,Beijing 100080,ChinaInstitute of Zookogy,Chinese Research Academy of Environmental Science,Beijing 100012,China 1990Journal of Environmental Sciences1990,2,4:1
4Development of Anti-Creep Andalusite-Based Bricks for Blast Furnace Stove显示文摘Secondary mullitization and mineral phase compositions of reacting andalusite of different gain sizes with fine alumina powders are studied. By adopting reasonable process technology to control mullitization behavior during firing, good anti-creep andalusite bricks have been developed.LIU Xiongzhang , ZHAO Huimin and CAO Hongfa(Luoyang Refractories Group Co., 471039, Henan, China) 2003China's Refractories2003,12,2:1
5Study on the toxicity of acid rain to microbiota in soils显示文摘With simulated acid rain and acidification, the soils from both Nanning and Liuzhou municipalities, Guangxi Zhuang Nationality Autonomous Region have been studied to determine the counts of azotobacter, bacteria, actinomyces and the activity of urease in soils, and the changes in respiratory intensity of soil so as to identify the toxicity of acidic substances to microbiota and enzyme in such soils. The concept of the critical pH of toxicity has been developed and used to discuss the representation of the concept, the basis on which the soil treated with simulated acid rain can be taken as an object of study, and the criteria for the identification of toxicity. Based on that as mentioned above, it was found that acid rain behaved to have toxicity to the microbiota in soils from Liuzhou other than from Nanning. The findings may be regarded as an objective basis to study the toxicity of acidic substances to microbiota and enzyme in soils in this region.Liao Ruizhang , Cao Hongfa, Liu Liangui and Gao JinlanInstitue of Soils and Fertilizers,Chinese academy of Agricultural Sciences,Beijing 100081,China.Institue of Ecology,Chinese Academy of Environmental Sciences,Beijing 100012,China 1991Journal of Environmental Sciences1991,3,2:0
