The influence of ionic surfactants,cetyltrimethylammonium bromide（CTAB）,self-assembled within silica-nanochannels of a hybrid mesoporous silica membrane（HMSM） on simple ion transfer（IT）behaviors at the meso-water/1,2-dichloroethane（W/DCE） interface arrays supported by such a HMSM was investigated by voltammetry for the first ***,it is found that the CTAB in HMSM can dramatically enhance the peak-current responses corresponding to ITs of some anions and even lower their Gibbs transfer energies from W to DCE,which could be ascribed to an anion-exchange process between anions and the bromide of CTAB associated with partial ion-dehydration induced by the *** work will provide a new strategy to study anion transfer processes and improve the electroanalytical performance for anion detection at the liquid/liquid interface.

目的为了研究深部强矿压工作面水力压裂裂纹扩展规律,方法以余吾煤矿的3号煤层S5207回风巷为工程背景,首先建立水力压裂力学模型,分析最大周向拉应变准则和裂纹扩展准则,其次通过三维数值模拟,分析水力压裂裂纹扩展影响因子D和地应力对水力压裂裂纹扩展规律的影响,并根据现场情况设计水力压裂试验方案,实施水力压裂增透技术,分析现场施工效果。结果结果表明:预制裂纹沿着与原裂纹呈一定角度开裂并向外延伸,其扩展方向最终与最小主应力方向垂直;随着D增大,裂纹与原裂纹的夹角越来越小,当D较大时,裂纹呈现自相似的扩展状态;不同应力场下,裂纹扩展轨迹主要取决于主应力方向,最终与最小主应力方向垂直,水力裂缝为垂直缝,且在裂纹尖端有应力集中现象;现场监测发现,裂纹扩展符合最大周向拉应变准则,裂纹尖端沿着环向拉应变最大的地方扩展,环向拉应变达到最大时裂纹开始扩展,压裂过程中出现了较大环向裂隙,裂纹沿垂直于最小主应力方向延伸,与S5207回风巷的最大水平主应力方向大致相同,与数值模拟结果接近。结论研究结果可为深部强矿压工作面水力压裂提供参考和依据。

AIM: To evaluate the medical quality of ophthalmologic perioperative period during 2010-2012 in our hospital. METHODS: The relevant data of perioperative period were collected in our hospital during 2010-2012, and the medical quality of perioperative period was evaluated by using the traditional evaluation indexes and adverse events. Whereby, the traditional indicators include vision changes, improving of intraocular pressure, diagnostic accordance rate before and after operation, cure improvement rate, successful rescue rate, and incidence of surgical complications, etc Adverse events are associated with ophthalmologic perioperative events including pressure sores, postoperative wound infection, drug adverse events, and equipment related adverse events. RESULTS: There were 1483, 1662 and 1931 ophthalmic operations in our hospital in the year 2010, 2011 and 2012, respectively. From traditional index analysis, the proportions of vision improvement for each year were 96.43%, 96.76% and 97.32%, respectively; the rates of intraocular pressure improvement were 87.50%, 85.72% and 90.17%, respectively ( P <0.05); the diagnostic accordance rates before and after operation were 99.86%, 99.94% and 99.90%, respectively; cure improvement rates were 99.73%, 99.93% and 99.84%, respectively; the successful rescue rates were 82.98%, 81.46% and 76.66%, respectively; the complications incidence rates were 18.44%, 17.52% and 17.97%, respectively. The negative factor analysis results showed that: among all the patients of ophthalmic surgeries in our hospital during 2010 and 2012, only one case of postoperative wound infection was found in 2011, and also only one case of tumbling in 2010. The adverse drug events for each year were 1 case (0.07%), 2 cases (0.12%), and 4 cases (0.21%), respectively; the medical device adverse events for each year were 3 cases (0.20%), 5 cases (0.30%), and 6 cases (0.31%), respectively. Noticeably, only one case with postoperative infection of endophthalmi

Nowadays, limited predictability and controllability of wind power are regarded as some bottlenecks to wind generation integration with the power system. This paper introduces a robust reserve scheduling method, where the spinning reserve allocation among conventional units is considered as *** method applies to asymmetrical wind power distribution,and offers control on the degree of solution's conservatism by changing the robustness budget. Meanwhile, distributional information of wind power is represented by mean value and asymmetrical bounds. Furthermore, the model is converted into a deterministic programming problem with dual theory. Case studies for asymmetrically distributed wind power illustrate its effectiveness.
