作者： GAO YAN li likun

THE express train of the Chinese economy can only keep going when its fuel tank is full. like any part of the world, China depends heavily on electricity. In China’s case its power supply comes primarily from coal-burning power stations. With a tremendous trove of the flammable black rock, Shanxi Province in north China is traditionally the locomotive of the nation’s power industry. During an inspection of the province in July 2005, President Hu Jintao commented: "As a major coal producer, Shanxi should take advantage of its

Journal of life Sciences 2012年第1期6卷 14-19页

作者： Zhangyong li likun Xu Zhui Xu Biomedical Engineering Research Centre Chongqing University of Posts and Telecommunications Chongqing 404100 China

In order to assess gastric motility, a new noninvasive method was addressed. Firstly, bio-impedance and stomach electric signals were recorded from the healthy control group and the pathologic stomach group. Wavelet transform was used to remove the influence of the heart activity signals. By analyzing and processing the two signals of the time domain and frequency domain, we get the corresponding parameters of the two groups. According to all the parameters, several verification tests have been carried out, from the result of the statistics, we can find that in both time and frequency domains, impedance signal and synchronize EGG （electrogastrogram） have some similar features. However synchronize EGG cannot be totally instead by gastric motility, especially in morbid state, EGG is not correspondence to impedance signal. The gastric contraction or gastric emptying is a complex procedure including electrical and mechanical activity. Electrical impedance （EIP） and the synchronous EGG should be analyzed together. In conclusion, the parameters have the value to evaluate gastric motility.

利用OM、SEM和TEM等观察分析了未添加La和添加La的17wt%Cr铁素体不锈钢的组织和第二相;测定了塑性应变比、应变硬化指数和电化学再活化率;确定了热轧再结晶的工艺参数。结果表明,两种合金中的主要第二相均为TiN;添加La后,合金铸态组织中存在柱状晶,热轧再结晶温度降低,塑性应变比得到提高,加工硬化性能和耐晶间腐蚀性能基本不变。
