目的  通过使用管道护理标识，降低管道不良事件风险，消除护理安全隐患。方法  在全院临床科室使用统一的管道护理标识。结果  住院患者管道不良事件发生例数、特殊用药错误或并发症等例数明显下降，有统计学意义（P < 0.01）。结论  管道护理标识有助于降低管道不良事件风险，提高护理质量。Objective: With practical application of pipe maintenance signals, the risk of pipe adverse events is reduced, and potential safety hazard in nursing is deleted. Methods: Standardized pipe maintenance signals are used in all clinic departments in the hospital. Results: There are obviously decreasing rate in adverse events, specific medicine using mistake and complications, which has statistical significance (P < 0.01). Conclusion: Pipe maintenance signals contribute to reducing pipe adverse events so as to improve nursing quality

Enviromental Issues In China:The Consequences of Environmenatl Pollution

摘要 在过去的20年里中国的经济持续快速的增长。中国是世界上最大的发展中国家及工业大国，面临着双重的挑战保护好环境同时增强本国的经济力量。然而这样的飞速增长十分依赖于中国本身的资本和自然资源的损耗。 在这篇论文里我主要研究水污染对经济的损失及水污染对人体健康的影响及它们之间的关系。水污染是另一个在中国引起人们对健康问题的担忧，尤其在中国的农村地区。从2000年到2008年，地表水质在中国的南部地区得到改善，然而在中国的北部去在继续的恶化。在中国空气污染是另一个必须被指出来的环境污染问题。中国是世界上最大的煤炭消费和生产国。以煤为主的能源导致高浓度二氧化硫和颗粒连续空气污染.中国是目前最大...Abstract China has sustained remarkably rapid economic growth over the last 20 year.

A genuine four-partite entangled state

In a recent paper, a genuine four-partite entangled state is proposed [Y. Yeo and W. K. Chua, Phys. Rev. Lett. 96, 060502 (2006)], which has been found to have many interesting entanglement properties. We show this state is locally equivalent to some graph states.Comment: submitte
