One model is for calculating Anti-dumping rate which is obtained according to current regulations of Anti-dumping, but it is not optimal. The other is an optimal model of Anti-dumping which is obtained according to the maximum principle of domestic social welfare. Then, through the comparison of this two models in detail, several shortages have been revealed about Anti-dumping rate model based on current regulations of Anti-dumping. Finally, a suggestion is indicated that WTO and China should use the optimal model to calculate Anti-dumping rate.展开更多

Therefore, over the years, the topic has gained a considerable attention from the researchers to study and characterize this phenomenon. In present work, the experimental studies of breakage phenomenon in a stirred tank in the last four decades were reviewed. The review highlighted the investigated experimental conditions and the major findings concerning the breakage mechanism and the effect of operating conditions. The discrepancy and contradictions of the outcomes of those studies were specified and discussed. Experimental observations and conclusions concerning the breakage characterization parameters,such as deformation, breakage probability, breakage time, and breakage location were presented and commented on. Possible future refinements and prospective were recommended. The review indicated that there are clear discrepancies and contradictions between previous studies regarding the effect of some operating parameters and the values of breakage time, breakage probability, number of daughter particles, and breakage location relative to the impeller. In addition, there are still many scientific gaps that need to be studied and characterized in future by overcoming specific experimental difficulties and uncertainties.展开更多

目的:运用网状Meta分析不同中药注射液治疗糖尿病周围神经病变(DPN)的疗效和安全性。方法:基于PubMed、Cochrane Library、EMbase、Web of Science、国家知识基础设施数据库(CNKI)、中文科技期刊数据库(CCD)、中国学术期刊数据库(CSPD)...目的:运用网状Meta分析不同中药注射液治疗糖尿病周围神经病变(DPN)的疗效和安全性。方法:基于PubMed、Cochrane Library、EMbase、Web of Science、国家知识基础设施数据库(CNKI)、中文科技期刊数据库(CCD)、中国学术期刊数据库(CSPD)、中国生物医学文献数据库(CBM),检索中药注射液治疗DPN的随机对照试验(RCTs),将临床总有效率作为主要结局指标,正中和腓总的感觉神经传导速度(SCV)及运动神经传导速度(MCV)、空腹血糖(FBG)及不良反应作为次要结局指标。采用Cochrane评价手册5.3风险偏倚评估工具进行质量评价及RevMan 5.4.1及Stata 17软件进行数据分析。结果:共纳入76项RCTs,包括6 108例患者,11种中药注射液。网状Meta分析结果显示,丹参多酚酸盐注射液联合西药在提高临床总有效率和改善FBG水平方面疗效最佳;苦碟子注射液联合西药在改善正中神经及腓总神经的SCV、正中神经MCV方面疗效最佳;血塞通注射液联合西药在改善腓总神经MCV方面疗效最佳;在安全性方面,中药注射液联合西药与单纯西药治疗比较差异无统计学意义。结论:中药注射液联合西药与单纯西药治疗比较可提高DPN临床疗效,且未增加不良反应的发生。展开更多
