煤矸破碎粒度分布规律的分形特征试验研究
郑克洪,杜长龙,
煤炭学报 , 2013,
Abstract: 为寻找煤矸破碎粒度的分布规律,根据分形理论建立了煤矸破碎粒度分布的分形表达式,并与威布尔分布比较,寻找煤矸破碎特性指数、破碎程度参数、分形维数与各影响参数的关系。首先对不同杆数的滚筒进行煤矸破碎试验,根据实验结果选择合适的杆数,并对参数间的关系进行探讨;其次,对不同杆形的滚筒进行煤矸破碎实验,根据实验结果确定杆形对煤矸破碎粒度分布的影响;最后对不同地质条件下的煤矸进行破碎实验,研究不同硬度的煤矸对煤矸破碎粒度分布的影响。研究结果表明:杆数为6、杆形为三角杆的滚筒破碎效果最好。威布尔分布、分形分布均可表示煤矸破碎粒度的分布规律,但用分形分布表示煤矸破碎粒度的分布规律,能更好地表达煤矸破碎粒度的的分布规律,可以更好地指导生产。
延续护理在我国肠造口护理中的研究现状及展望

Nursing Science (NS) , 2014, DOI: 10.12677/NS.2014.33010
Abstract:
肠造口患者在出院后将面临长时间的造口自我护理的问题,需要医疗体系与家庭的持续支持与护理。延续护理被认为是改善患者生活质量、保证患者生命安全的重要方式。延续护理作为住院护理的延伸,可给予患者不间断的护理干预,最大限度地提高患者及家属参与护理的能力和对造口相关知识的掌握程度。通过电话干预、家庭访视、门诊随访、造口联谊会、同伴教育、社区护理、网络教育等方式对造口患者进行延续护理,使得患者在生活质量、自我护理能力、自尊、依从性、社会心理适应等方面得到了很大提高。
Colostomy patients discharged from hospital faced the problem of long-term ostomy self-care; they need the continuing support and care from health care system and the family. Continuing care is considered to be an important way to improve the quality of life of patients and ensure the safety of patients. As an extension of hospital care, continuing care may give the patient continuous nursing intervention to maximize the ability to care for patients and their families to participate in and mastery of stoma-related knowledge. Through telephone intervention, home visits, outpatient follow-up, ostomy associations, peer education, community care, network education and other ways to provide stoma patients with continuing care, patients’ life quality, self-care, self- esteem, compliance, social psychological adaptation, etc. have been greatly improved.

 [PDF]

徐靖宇,
Geographical Science Research (GSER) , 2016, DOI: 10.12677/GSER.2016.52009
Abstract:
本文基于GIS空间分析技术进行流域信息分析,结合坡度、地形起伏度等地形特征,利用逆流原理对湖南省山洪沟边界信息进行提取,结果表明:1) 湖南省山洪沟多分布在湖南省西北部、南部和中部山区。与降水分布进行对比,发现这些地区降水分布相对集中,且出现强降水的概率较大,出现山洪灾害的风险较高。2) 对山洪沟预测指标进行等级分级,用不同等级值反映了山洪灾害发生的概率,可以看出提取的山洪沟位置信息与实际发生山洪灾害的位置有很好的对应关系。说明山洪沟的分布能在一定程度内反映出山洪灾害的发生地点。3) GIS提取结果与历史普查的山洪灾害发生区域进行叠加分析,相似度较高,较好的验证了山洪沟提取的可靠性。
In this paper, GIS spatial analysis technique is based on watershed information analysis, combined with slope, terrain ruggedness, and other terrain features, to extract flash floods ditch of Hunan. The results showed that: 1) Flash floods ditches are located in mountainous areas of northwestern, southern and central in Hunan Province. Compared with the distribution of precipitation, rainfall distribution is concentrated in these areas, and both the probability of heavy precipitation and risk of flood disasters are higher. 2) Used different levels of value to reflect the probability of flash floods disasters, we can see that it has a good relationship between flash flood position by extracted and the actual location of flood disasters. To some extent, the distribution of flash floods ditch also has been reflected the occurrence of flood disasters in place. 3) The results can reflect the Flash floods ditch extraction reliability compared with the history fact of flash flood disasters.
企业年金会计准则的国际比较及启示

财会月刊 , 2006,
Abstract: 我国关于养老金会计方面的理论研究起步较晚,相关会计准则的制定也还停留在征求意见阶段,而关于企业年金的规范更是很少涉及。如何借鉴国外较为成熟的研究成果与实践经验来构建我国企业年金会计准则,使其与各相关制度相协调并促进企业年金会计的健康发展已成为亟待解决的问题,本文对此作以下探讨。  一、企业年金会计准则的国际比较  西方各国对企业年金大都制定了较为详尽的会计规范,笔者仅以国际会计准则(IAS)、美国财务会计准则(FAS)和英国财务报告准则(FRS)为比较对象。  三者在进行会计核算时均把年金计划分为设定提存计划和设定受益计划。在设定提存计划下,年金的会计处理较为简单,三者均要求在雇员为企业提供服务的每一期,将应付给设定提存计划的提存金确认为当期费用。但对设定受益计划的处理要求,三者却存在一些差异。

This paper puts forward a computational method for the problem of predicting protein subcellular localization. It uses features of the position specific scoring matrix (PSSM)and gene ontology (GO),and uses the support vector machine (SVM) to construct a classifier. This method considers the effect of evolutionary information to the subcellular location and also employs text mining method a logarithmic transformation of CHI to determine weight for GO features to achieve higher precision. Furthermore,using SVM as base classifier to construct multi-label classification model,it is performed on two benchmark datasets. The application result shows that the proposed method effectively improves the accuracy of prediction of protein subcellular localization

Abstract: 从口岸效率、关税环境、基础设施及服务、信息和通信技术、商务环境五个方面遴选若干指标,运用德尔菲法和层次分析法构建了对贸易便利化进行科学测评的综合指标体系,并合理确定了各指标的权重指数,将贸易便利化指标作为自变量导入传统贸易引力模型,对原模型进行修正。采用我国的25个主要贸易伙伴的数据,对模型进行了实证检验。回归结果表明,包括贸易便利化指标在内的自变量很好地解释了我国出口贸易的情况。同时,这个结果也反证了本文提出的模型贸易便利化测评指标体系构建合理,有较强的说服力。
The index system selects certain indicators from five perspectives such as port efficiency, tariff environment, infrastructure and service, information and communication technology and business environment. Analytic Hierarchy Process (AHP) was used to construct a comprehensive index system of trade facilitation under open environment,and Delphi method was used to identify the weight of each index. The empirical results of trade facilitation on China's 25 major trading partners showed that China's level of trade facilitation remains at a low and middle level worldwide. On the basis of the index system, a trade gravity model on trade facilitation index system has been set up based on modification of Linnemannn Model. Empirical research results on China's major trading partners have showed that the new model is much more accurate and its goodness of fit is better. Meanwhile, empirical research results also showed that the trade facilitation index system is much persuasive and reasonable.
