摘要：齐白石是我国家喻户晓的国画大师,无论是在美术史还是市场中,他都是一位赢家。他的艺术风格对当时、现下乃至以后的国画艺术发展都有深远的影响,同时,他的书画作品随着市场经济的发展价值也是一路攀升,在市场上占有举足轻重的地位。本文首先讲述齐白石的艺术人生和艺术风格,介绍其作品的艺术价值,通过对艺术作品和市场研究,解释齐白石的书画作品在艺术市场上占据高份额的原因。

摘要：Mechanoluminescent(ML)materials can directly convert external mechanical stimulation into light without the need for excitation from other forms of energy,such as light or *** alluring characteristic makes ML materials potentially applicable in a wide range of areas,including dynamic imaging of force,advanced displays,information code,storage,and anti-counterfeiting ***,current reproducible ML materials are restricted to sulfide-and oxide-based *** addition,most of the reported ML materials require pre-irradiation with ultraviolet(UV)lamps or other light sources,which seriously hinders their practical ***,we report a novel ML material,MgF_(2):Mn^(2+),which emits bright red light under an external dynamic force without the need for pre-charging with UV *** luminescence properties were systematically studied,and the piezophotonic application was *** interestingly,unlike the well-known zinc sulfide ML complexes reported previously,a highly transparent ML film was successfully fabricated by incorporating MgF_(2):Mn^(2+)into polydimethylsiloxane(PDMS)*** film is expected to find applications in advanced flexible optoelectronics such as integrated piezophotonics,artificial skin,athletic analytics in sports.

摘要：目的:设计儿童早期预警评分(Pediatric Early Warning Score,PEWS)电子病历系统信息化平台,形成PEWS评估-提醒-处置流程,并分析其应用效果。方法:依托医院信息化平台,设计PEWS电子病历系统内容与架构。选取符合纳入标准的住院患儿300例,将患儿随机分配至人工评估组(n=150)和电子病历系统评估组(n=150),比较两组评估耗时和准确率以及护士对两种评估方法的满意度。结果:采用电子病历系统耗时短于人工评估方法[(31.18±3.76)s vs(55.64±5.01)s];电子病历系统评估正确率高于人工评估组(100.0%vs 82.7%);护士使用电子病历系统评估满意度高于使用人工评估(97.8%vs 80.0%)。结论:PEWS电子病历系统评估的应用可提高护士的工作效率、病情评估的准确率以及护士的满意度。

摘要：文章基于知识组织理论,提出了术语词典知识表示的基本模型,作为术语词典编纂系统的知识框架。对术语词典辅助编纂的系统架构进行设计,分解为三个核心功能模块,将基于语料库的术语计算、数据可视化、用户交互模块紧密结合,直接服务于术语词典的编纂,提高知识生产效率。
