混和硅油测定玻璃折射率

目的建立混合硅油测定单纯用B油和C油无法测定的玻璃折射率的方法。方法将B油和C油分别按1:2和2:3的体积比配成两种混合硅油,用此两种混合硅油测定同一块玻璃的折射率。结果用此两种硅油测得的玻璃的折射率结果无显著性差异。该方法克服了玻璃折射率仪温度范围窄(25℃～125℃)的缺点。     

Beyond privatisation and cost savings: alternatives for local government reform

Unsatisfactory results from privatisation have caused local governments to seek alternative reforms. Inter-municipal cooperation, mixed public/private delivery and contract reversals are three alternatives that have gained traction in the last decade. These alternatives help local governments manage markets for public service delivery as a dynamic process. They maximise government/market complementarities and address a wider array of public goals beyond cost efficiency concerns. The alternative reforms show how local governments balance citizen, labour and community interests to ensure efficiency, coordination and stability in public service delivery.     

三石生新膏外敷治疗混合痔术后肛缘水肿疗效观察

目的观察三石生新膏外敷治疗混合痔外剥内扎术后肛缘水肿的临床疗效。方法将80例混合痔术后肛缘水肿患者随机分为治疗组和对照组,每组40例。术后第2天开始,两组均用黄柏煎液坐浴,治疗组加用三石生新膏外敷,对照组加用50%硫酸镁湿敷。于术后第7天观察两组患者肛缘水肿消退情况,比较两组创面愈合时间。结果治疗组术后肛缘创面水肿消退的效果显著优于对照组(P=0.007),创面愈合时间较对照组显著缩短(P=0.001 1)。结论三石生新膏外敷可促进混合痔术后肛缘水肿消退,缩短创面愈合时间。
