我国建立农村最低生活保障制度思考

摘要: 我国现行最低生活保障制度主要侧重解决城镇贫困问题。随着我国国民经济的发展及我国最低生活保障制度的进一步完善, 建立农村最低生活保障制度将成为政府的必然选择。新型的农村最低生活保障制度应在救济内容、救济方式、救济标准、救济周期、救济资金的来源等方面有别于城镇最低生活保障制度, 应采取教育救助等措施加以解决。本文为国家社会科学基金项目(批准号: 03BJL038) 研究成果之一

Study on the Changes of Physical Health Status of Students from P.E.Teaching Reform

运用文献资料法、测试法、比较分析法、数理统计法等研究方法,以厦门大学三学期制为背景,以概括总结近8年来我校体育教学深化改革为出发点,对我校2005、2007、2009、2012年学生体质健康监测结果进行比较分析,以期了解我校学生体质健康水平的变化情况,为大学体育教学改革指明方向。结果表明:我校实行三学期制以来,体育教学改革不断深化,学生体质健康状况整体良好,不仅总体水平逐年提高,而且学生的身体形态、机能、素质均得到不同程度的改善;身体形态方面,我校学生肥胖率有所下降,但超重和营养不良的比例有所提高,其中女生变化幅度明显大于男生;身体机能方面,我校学生总体上处于良好以上,女生的整体水平好于男生。身体素质方面,我校学生上下肢力量处于“失衡“状态,这种现象应引起高度重视。The paper is using the method of literature,test method,comparative analysis,mathematical statistics and other research methods to analyze the students,physical health monitoring result of our school in the years of 2005,2007,2009 and2012,taking the three-semester system of Xiamen University as the background and summarizing the recent 8 years of the P.E.teaching reform as the starting point.This is to understand the change of physical health level of students of our school.It can become the direction of the university sports teaching reform.The results show that:our school deepens the reform of P.E.teaching after the three-semester system,students' physical health condition is good and improved in different degrees not only the overall level but also the body shape,function and quality;our students,obesity rate has declined in body shape,but the overweight and malnutrition has increased.The proportion of girls was significantly more than boys;our students,physical function is more than good and the girl's overall level is better than boy's;physical fitness,our students,upper and lower extremity strength is in the"imbalance"state.The phenomenon should cause height to take seriously.2011年福建省教育厅A类社会科学研究项目(JA11008S

Research progress on the Agrobacterium-mediated medicinal microalgae genetic transformation system

农杆菌介导的遗传转化具有操作简便,转化率高,可低拷贝和大片段整合外源基因在宿主染色体上等优点,已经在植物中广泛应用。微藻作为一种重要的种质资源,是多种功能活性产物的初级生产者,在药物开发方面极具发展潜能。农杆菌介导的转化体系在部分微藻中获得成功,有效提高了药用活性产物的生产效率,改良了微藻的生理性能,为微藻药用资源的大规模工业化生产奠定了基础。本文综述了微藻来源的药用功能产物及农杆菌转化体系在微藻中的研究现状和影响转化效率的因素,并展望了该技术在药用微藻中的应用前景,为药用微藻资源的基因工程改造提供一定的参考和借鉴意义。Agrobacterium-mediated genetic transformation has been widely used for plants, owing to its merits such as operation simplicity, high efficiency of transformation, and transferring a large segment of foreign DNA with low copy of the transgene(s) into host chromosomes. Microalgae are known as germplasm resources and primary producers of a variety of functionally activated products. It also possesses great potential in the development of pharmaceutical exploitation. Agrobacterium-mediated genetic transformation system has been established successfully in some microalgae. This technology has efficiently increased the productivity of medicinal activated products and improved the physiological performance in microalgae, thus laying foundation for the mass production of medicinally valuable microalgae at large-scale. This paper summarizes the medicinally activated products from microalgae, the research progress on the Agrobacterium-mediated genetic transformation in microalgae as well as the factors affecting transformation efficiency, the application prospect of this technique in medicinal microalgae, and ultimately providing certain reference to the genetic engineering of medicinal microalgae.海洋公益性行业科研专项经费项目(No.201505032);; 厦门南方海洋研究中心项目(No.14GZP021NF21

双压电驱动高频喷射点胶阀的设计与实验

为了满足电子封装产业对胶体高速、微量分配的需求,设计了一种基于圆弧柔性铰链放大机构的双压电陶瓷驱动喷射点胶阀。首先,利用有限元分析软件对放大机构输出位移和模态进行了计算与分析。针对其高频需求,讨论了结构参数对其影响因素。基于微元法并结合喷嘴内胶体动力学分析,建立了喷嘴内胶体喷射的流体力学模型。结合阀杆与阀座配合的仿真模型,利用FLOW-3D的流固耦合仿真,揭示了喷射点胶时胶点的成型过程。在此基础上探究了胶体喷射时喷嘴处压力的变化与流速的关系,为点胶阀参数的控制和优化奠定了基础。最后,搭建了喷射系统实验平台,选用黏度为180cps的胶体进行点胶性能测试,得出了供料压力和驱动方波频率对胶点尺寸的影响规律。实验结果显示,在供料压力为6bar,驱动方波幅值频率360Hz等参数下,获得胶点最小直径为525μm。同时,在380～400Hz的频率区间内进行高频喷射实验,能够获得均匀微小的圆形胶点。实验结果验证了该圆弧柔性铰链放大机构的双压电驱动点胶阀的高频、微量喷射性能,为压电高频喷射点胶的应用和研究提供了参考。深圳市科技计划资助项目(No.JCYJ20170818141912229);;\n航空科学基金资助项目(No.20160868004
