基于无线传感器网络的心电信号监测系统

健康监测是无线传感器网络的一个重要的应用方向。本文给出了基于无线传感器网络的心电信号采集系统设计。该系统利用INA118仪表放大器对心电进行放大;采用Jennic公司的JN5139芯片设计微型无线传感节点,网络采用Zigbee协议。系统具有体积小、功耗低,成本低的特点。对人体进行的实测结果表明,系统能够实现实时心电监测。     

节能量保证型合同能源管理项目的收益分配

收益分配是影响合同能源管理项目顺利实施的主要因素之一。从利益相关者视角,分析节能量保证型合同能源管理项目中主要的利益相关者,给出其合作条件;以Shapley值为工具,得出节能量保证型合同能源管理项目收益分配方案,运用算例进行了验证。研究结果表明,Shapley值法能够较好地解决节能量保证型合同能源管理项目利益相关者的收益分配问题;节能量保证型合同能源管理项目利益相关者组成合作联盟,不仅提高了各自的节能收益,而且节能总收益最高。     

基于Workbench的某V型六缸柴油机机体有限元分析

为了保证V型六缸柴油机机体的强度和可靠性满足设计要求,使用Solidworks建立了机体的实体模型,运用ANSYS Workbench的静力分析模块和Fatigue tool工具包,对机体各个气缸在最大爆发压力下的强度和可靠性进行分析。结果表明：其原有结构设计满足强度和可靠性要求,机体位移较大位置主要分布在机体缸盖螺栓附近,而出现应力集中的位置主要是机体上部、下裙部、轴承盖连接螺栓及其附近隔板区域。     

民初政党政治与民主思想

民国初年,政党政治以失败而告终,但对近代民主思想的发展却产生了很大影响:伴随政党政治的展开,民主思潮随之勃兴、高涨;民主思想趋向于本土化、民族化;近代民主的追求也在冲突中得以反思、融合,在失败中走向转变.     

论近代中国国家主权的缺失

中华民国的创立实现了传统皇朝体制向近代民族国家的艰难转型,但在近代中国的国家建设中,从北洋军阀的专权到国民党的法西斯独裁,其国家主权却长期处于缺失状态,主要表现为两点:一是晚清旧条约的继承和民国新条约的签订;二是中央政府对国家仅是形式上的统一.     

某承台大体积混凝土施工裂缝控制技术研究

大体积混凝土施工是现代大型土木工程中的特种技术，工程技术人员必须从理论上认清制约大体积施工质量的基本原因。以工程实践为例分析了大体积混凝土温度应力形成机理，进行了大体积混凝土裂缝控制的施工详细计算，提出了切实可行的裂缝控制施工技术措施，对类似工程有一定借鉴作用。     

新贸易形势下中国能源经济预测与展望

随着2018年以来中美贸易摩擦升级等国际贸易形势的变动,中国经济迎来了新的机遇与挑战。在新贸易形势与中国内部产业升级的共同影响下,中国能源行业在快速发展的同时也面临调整压力。从行业角度阐述新贸易形势下中国能源经济发展前景,并通过情景分析对各能源行业与能源密集型行业的产值与能源消费进行预测,探讨新贸易形势下中国能源经济发展趋势和路径。根据预测结果,中国能源消费结构将持续优化,中美贸易摩擦对中国宏观经济影响并不十分显著,但是仍对某些能源与能源相关行业的产值与能源消费具有一定的不利影响。中国应从重点行业着手,多手段应对新贸易形势下能源经济波动。     

Protecting the Right to Life of Children with Disabilities in China

ABSTRACT

Chinese social policy to support parents in caring for their children is vital to address the urgent social problem of abandoning the life of children with disabilities by not seeking medical treatment. The child rights approach was used to analyze the effectiveness of Chinese social policy to protect the right to life of these children. Primary and secondary empirical data from 3 case studies where parents decided whether to abandon their child were analyzed. Did the child protection mechanisms protect the right to life of these children, and when did parents decide to abandon their children? The findings were: a) When the children were born, their right to life was not unconditional; b) the decision was made privately by parents—no formal decision procedure was available, the role of professionals was minimal, and the state did not intervene; and c) parents considered the disadvantages to their children if they lived. The implication is that China has not yet established a system to support parents and protect the lives of young children with disabilities. Future research to inform child protection reform and disability support to children and families to prevent children becoming abandoned is urgently needed.     

Social Support for Mothers of Children With Disabilities in China

ABSTRACT.

This article analyzes the gendered parenting experiences of mothers of children with disabilities in China. These mothers struggle to meet their children's needs, including daily care, financial security, and child development. In the context of China's social welfare development, are social services responding to their needs, so that mothers can share responsibility for the needs of their children with disabilities? The research analyzed qualitative data about 6 case-study children in rural and urban China. The data were derived from observation and interviews with their parents and other family and community members. The analysis revealed that the capacity of the mother, community, and local social services had an impact on the rights of the children and mothers. They experienced social discrimination, insufficient social support, and local failure to implement central policy social services and income support. These findings are consistent with international research about disability rights. They reinforce the importance of economic redistribution to enable local implementation of the national disability rights policies, rather than merely relying on ephemeral concepts of cultural change. Further research about the comparative impact of economic and social change in China on mothers and children with disabilities would extend these findings.
