>Objective: The present study aims to optimize the extraction and purification procedure for polysaccharides from Thais clavigera Kuster. Method: We used water, ethanol to extract the polysaccharides and microwave-ultrasonic wave aided extraction. The effects of temperature, material- liquid ratio on the yield and ultrasonic power and the concentration of ethanol precipitation from Thais clavigera Kuster were investigated through the orthogonal analysis. Result: The optimum technology condition for extraction and purification of polysaccharides from Thais clavigera Kuster was determined as follows: temperature is 70, material-liquid ratio on the yield is 1:10, ultrasonic power is 600 w, the concentration of ethanol

Advances in Environmental Protection (AEP) , 2014, DOI: 10.12677/AEP.2014.46B005
Abstract:

本文在分析了生产建设项目防治措施布设原则的基础上,分析了影响防治目标达到因子,并对防治目标、防治指标、效益分析与措施配置关系进行了研究,提出防治目标是水土保持方案措施配置后必须达到的最低要求,效益分析是根据水土保持方案措施配置能够达到的防治指标,措施配置是达到防治目标的方法。

This article based on the analysis of the development and construction projects for control measures layout principle, analyzed the influence factor of the control goal, and researched control goal, control index, benefit analysis and measure allocation relation. It puts forward that control goal is the minimum requirement plan of soil and water conservation measures. Benefit analysis is control index to achieve the plan of soil and water conservation measures, and measures allocation is method to achieve control goal. 

论正犯与共犯的区分——立足于我国刑法规定之检讨
飞飞
比较法研究 , 2014,
Abstract: 基于正犯理论的实质化演进,现在通行于大陆法系国家关于共犯分类标准的分工分类法已经大异其趣,这种修正了的分工分类法试图在分工中解决不同类型共犯人刑事责任的大小问题而更接近于我国的作用分类法。我国目前共犯分类理论应当将分工分类法与作用分类法相结合,发挥各分类法的应有功能,做到对共犯人准确定罪量刑。我国目前坚持正犯判断标准形式的客观说并对其适当修正更为现实和可行。在此基础上我国刑法中正犯与实行犯几乎可以合一把握。
三元复混肥和鸡粪肥中重金属含量特征分析与评价

湖南农业大学学报(自然科学版) , 2011,
Abstract: 为了解施肥对山东寿光市设施蔬菜土壤重金属输入的影响,采用随机取样的方法在寿光市收集了10个氮磷钾三元复混肥和21个鸡粪肥样品,测定了肥料中重金属Cu、Zn、Cd、Pb的含量。结果表明:鸡粪肥中Cu、Zn、Cd、Pb含量高于氮磷钾三元复混肥,但与中国有机?无机复混肥标准(GB18877—2002)相比,鸡粪肥中Cd未超标;2种类型肥料中的Pb均处于较低水平;每年通过施肥输入寿光设施蔬菜土壤的Cu、Zn、Cd、Pb量分别为3 516.282、23 731.500、19.473和69.011 g/hm2,其中鸡粪肥输入的量占肥料总输入量的79%~97%。
公司法中的权利倾斜性配置――实质的正义还是错位的公平
飞飞
安徽大学学报(哲学社会科学版) , 2013,
Abstract: 对权利进行倾斜性配置是保护弱势主体一方利益、彰显法的实质正义价值的惯用性方法。就公司而言,存在着小股东、员工等相关弱势主体,保护他们的既有与预期利益是维系公司效率化运营的前提性条件。然而,按照新制度经济学的观点,公司是与市场相对应的一种资源配置方式,科层制下的公司内部治理结构所支撑的是一种区别于平等主体之间市场交易关系的以“权威―服从”为特质的团结性关系,而权利倾斜性配置只能针对平等主体之间具有利益博弈性与对抗性的交易关系。因此,在公司中进行权利的倾斜性配置不应是保护弱势主体的应然性选择。

飞飞
铁道工程学报 , 2012,
Abstract: ?研究目的:黄土的应力和含水率状态对应着一定的结构状态,微观结构性的改变,引起宏观力学性状的改变。湿陷性黄土在力与水的共同作用下,产生原生结构性的损伤和湿陷变形,对增湿和加荷耦合作用下的结构性变化规律,应力应变关系和增湿变形等力学特性的研究有重要的意义。研究结论:不同含水率和固结围压条件下原状结构性黄土的应力应变变化规律,以及由增湿、固结作用和剪切变形反映了土体结构性损伤规律;统一考虑增湿和加荷对土体结构的损伤破坏,建立的反映结构性变化的非线性本构模型,能够描述应变软化和硬化型应力应变关系曲线,实现了土的结构性与其本构模型研究的统一。
