1Design theory and experimental investigation of the low frequency and high power rare earth magnetostrictive flextensional transducer (Ⅰ). Theoretical part显示文摘The energy relationships among all the elements, by which the magnetostrictive transducers are manufactured, in Finite Element Method (FEM) are analyzed, then the expres- sions of FEM dynamics equations and performances formulas for magnetostrictive transducers are derived. The vibrating modes of the class VII transducer and its shell vibration are calcu- lated theoretically and the results point out that there is a breathing mode and if the transducer works at this mode, the transducer will vibrate with a greater volume speed and source level.HE Xiping (Applied acoustic institute, Shaanxi Teachers University Xi’an 710072) (College of Marine Engineering Northwestern Polytechnic University Xi’an 710O72) SUN Jincai LI Bin (Colloge of Marine Engineering Northwestern Polytechnic University Xi’an 71 2001Chinese Journal of Acoustics2001,20,4:6

3Pulse source-system model and its amplitude versus frequency characteristics显示文摘The pulse contains most of information on the body health. In recent years, scholars,both at home and abroad, have been greatly interested in studying human pulse information using the modern scientific technology and methods. In this paper, we study the features and the physical process of pulse signal gcncration and initially establish a pulse source-system model on the basis of the information theory, the system theory and the acoustical theory. The model is proved to be rational by experimental testing and the new signal analysis techniques-the Cepstrum and Liftering Techniques. In this paper, the structures and features of the pulse acoustical-spectral diagrams are analysed for the first time and several conclusions on the physiological features of the pulse transmission system are drawn.WANG Binghe DONG Yanwu TU Haiying WU Shengju SHANG Zhiyuan TONG Jie JIN Xiuchan WANG Ruie(Applied Acoustics Institute Shaanxi Normal University, Xi’ an 710062)ZHANG Xiaomin WANG Haiyan XIANG Jinglin(Northwestern Polylechnical Uaiversity.

4In vitro Effect of Dithiocarbamate Pesticides and of CaNa_2EDTA on Human Serum Dopamine-β-hydroxylase显示文摘Serum dopamine-β-hydroxylase (DBH) inhibition has been reported in lead workers treated with CaNa2EDTA and in alcoholic patients repeatedly treated with the alcohol aversive drug Disulfiram. The mechanism of inhibition involves Cu-chelation at the active site of DBH. The effect of CaNa2EDTA and Disulfiram on serum DBH has been compared to the effect of dithiocarbamate pesticides in vitro for the possible use of serum DBH determination for the biological monitoring of workers exposed to these pesticides.Most dithiocarbamates inhibit human serum DBH at micromoIar concentrations (range of I50, 0.027-1.6 μmol/L). The inhibitory potency increased from methyl- and dimethyl dithiocarbamates to diethyl dithiocarbamates up to the most potent ethylene bisdithiocarbamates. The I50 of CaNa.EDTA was 3.8 mol/L, higher than those of dithiocarbamates. Copper addition to the test system rcactivated at stoichiometric concentrations dithiocarbamaie-inhibited DBH indicating that both base line values and percent of inhibition can be calculated in a single blood sample. Results suggest that serum DBH determination couId be useful in case of acute poisoning involving high doses of dithiocarbamatePAOLA DE PARIS AND STEFANO CAROLDI(Istituto di Medicina del Lavoro, Universita’ di Padova, Padova, Italy)(Send correspondence to: Dr. Stefano Caroldi.

5甲状腺乳头状腺癌颈淋巴结清扫术显示文摘我院在1952~1997年共治疗甲状腺癌2097例,其中乳头状腺癌1732例1954~1992年间乳头状腺癌1219例,男317,女902例,男女之比为1:2.85.年龄最小6岁,最大80岁,中位年龄37.68岁,S=12.72,行颈淋巴结清除术913例(71例行双颈清除术),共984例次。通过对913例(984例次)颈淋巴结清除术的分析及随访。预防性组淋巴结阳性率为66.32%,治疗性组为93.98%,预防性组10年以上无瘤生存率远高于治疗性组。治疗性组5年、10年无瘤生存率功能性组优于传统性组(P<0.01),预防性组10、15、20年无瘤生存率功能性组优于传统性组(P<0.005),说明功能性颈淋巴结清除术即保留功能又不降低生存率,是一种值得提倡的治疗方法。另外通过109例死亡原因回顾,死于复发和转移62例(56.88%),术后10年内死亡者占83.87%(52/62),术后10年以上复发机会明显减少。转移瘤多以肺转移为主,占71.4%。徐本义 高明 张艳 张学忠 姜辉春. 72) .

6构建人类命运共同体:文化因素与中国智慧——以中国文化和图书出版交流为例显示文摘坚持推动构建人类命运共同体,是党的十九大提出的新时代中国发展需要坚持的基本方略之一,是习近平总书记为推动人类社会健康发展贡献的中国智慧和行动方案。文章以出版文化为例,研究认为,在推动人类命运共同体构建中,更好地发挥包括中国文化在内的人类文化的巨大独特作用,要求我们努力寻求文化认同,使构建人类命运共同体有魂魄;积极促进文化交流,使构建人类命运共同体长筋骨;切实推动文化交融,使构建人类命运共同体可持续。有日益自信的中国文化作支撑,有中国智慧的贡献,有中国方案的推动,推动构建人类命运共同体必将成为造福全人类的伟大事业,必将成为全世界人民的诗和远方。中共中央党校(国家行政学院)第71期“推动构建人类命运共同体”研究专题班课题组 马国仓 倪嘉梁 黄丽云 谭作刚 戴绍利 2019中国出版2019,,15:2
7加强党的全面领导体制机制研究显示文摘将党的领导主要是政治、思想和组织领导上升为坚持和加强党的全面领导,是新时代党的建设重大理论创新。加强党的全面领导需要制度化设计,需要通过重构党和国家机构职能体系予以保障。十九届三中全会把加强党的全面领导作为首要任务,着力优化党的组织机构,从制度安排上确保党的领导全覆盖。《中共中央关于深化党和国家机构改革的决定》和《深化党和国家机构改革方案》以坚持和加强党的全面领导为主线,就完善坚持党的全面领导的制度进行了宏大而周密的顶层设计,从机构职能上把加强党的领导落实到各个领域、各个方面、各个环节。这次以加强党的全面领导为统领的改革给我们许多深刻启示:必须旗帜鲜明把加强党的全面领导作为最高政治原则;必须坚定不移把维护以习近平同志为核心的党中央权威和集中统一领导作为党的建设和政权建设的核心任务;必须始终坚持加强党的全面领导同坚持以人民为中心的高度统一;必须把坚持党的领导始终作为处理党政关系的根本前提。中央党校厅局级进修班(71期)“全面加强党的领导和党的建设”研究专题二支部第一课题组 阎红革 丁力 孔军 陈斌 周怡文 张志明(指导) 2018中国领导科学2018,0,6:2
