The Analysis and Research of Land Right in Urban-village Reforms——From A Point of View of Wenzhou City

纵观近几年的城市化进程，“城中村”改造起到了很大的促进作用。但是改造过程中土地权利处置不得当的问题比比皆是，给农民带来了巨大的损失，造成了无法弥补的心灵创伤。 论文首先对“城中村”的概念进行解释，分析“城中村”改造在中国城镇化进程中的必然性，及对农民带来的影响。对我国现有的土地管理制度、“城中村”改造中的土地权利问题及城中村改造政策存在的弊端进行了分析，着重研究几个重要问题，如土地性质二元制、身份二元制、现行法律制度的不完善等。在现有的国家法律体系中，土地征用、房屋征收与补偿的相关规定几乎是散布在有关法律条文中，要么是一些效力层次较低的地方规范性文件。通过对实际工作中遇到的困难和问题的分析，...In recent years, urban-village reform improved the city and made a rapid progress of urbanization. But sometimes the local government damaged the land right of peasants which made them loss their property. So the people of the urban-village don’t believe the government anymore. They hate the process. At first, the article explains the concept of urban-village, analyzes that the urban-village refo...学位：法学硕士院系专业：法学院_法律硕士(JM)学号：X201012007

Effects of Fe and Mn on growth and cell size of Alexandrium tamarense under different culture conditions

研究了单种和两种混合批量培养条件下,Fe2EDTA(Fe3+)、Mn(Mn2+)浓度对甲藻塔玛亚历山大藻( Alexandrium tamarense) 生长及细胞大小的影响,同时考察了与其混合培养中的中肋骨条藻( Skeletonema costat um) 和圆筛藻( Cosci nodiscus sp.)的生长特性.结果表明:在本实验的浓度范围内(Fe2EDTA ,0 —3115μg/L;Mn2 + ,0—118μg/ L) ,铁、锰浓度的升高对单独培养条件下的3 种藻类的生长均有不同程度的促进作用,揭示了微量元素铁、锰是触发赤潮发生的重要因子之一;在混合培养条件下(甲藻－硅藻) ,细胞较小的中肋骨条藻和圆筛藻在竞争中处于优势地位,塔玛亚历山大藻在一定时间的混合培养后衰败. 不同铁、锰浓度及不同培养条件对塔玛亚历山大藻细胞大小有显著影响.国家自然科学基金重大基金项目(编号:39790110) 资

Preliminary study on PAH degradation by bacteria from contami-nated sediments in Xiamen Western Sea, Fujian, China

In order to estimate the biodegradation of three polycyclic aromatic hydrocarbons (PAHs) compounds, bacterial strains were isolated from marine sediments in three heavily contaminated sites (Yuandang Lake, Dongdu Port and Aquacultural zones in Maluan Bay) in Xiamen Western Sea. The results show three bacterial strains, which used pyrene as the sole carbon source, were identified as strains of Aureobacterium sp., Arthrobacter sp., Rhodococcus sp. The PAH-degrading bacteria isolated had a strong ability to degrade phenan-hrene, fluoranthene and pyrene at different degradation rates. The highest degradation rate was observed when three PAH compounds were mixed with an individual strain in the medium. The three PAHs were degraded after one week with a degradation rate of 89.94 % for phenanthrene and 93.4 % for both of fluoranthene and pyrene. In addition, after 25 days of incubation, the degradation rate was 99.98 % for phenanthrene and 99.97 % for both of fluoranthene and pyrene. Optical density was measured to ..

黑龙江林蛙输卵管金属元素、维生素的测定

用ＰＥＲＫＩＮ—ＥＬＭＥＲ５０００型原子吸收分光光度计和岛津ＬＣ—３Ａ高效液相色谱仪对黑龙江林蛙（多只混合）输卵管阴干制品中八种金属元素和维生素Ａ、Ｅ的含量进行了测定。测定结果为：钾、钠、钙、镁、铁、锰、锌、铜、维生素Ａ、维生素Ｅ分别为：０．８６％、０．２７％、０．１８％、０．０２７％、５５．９２μｇ／ｇ、２３．０８μｇ／ｇ、１４．９２μｇ／ｇ、８．２５μｇ／ｇ、０．１７０２ｍｇ／ｇ、０．０４２８ｍｇ／ｍ（伊春）；０．８１％、０．４０％、０．０７５％、０．０３０％、７０．００μｇ／ｇ、２４０８μｇ／ｇ、１８．８３μｇ／ｇ、７．８３μｇ／ｇ、０．１００６ｍｇ／ｇ、０．０３２４ｍｇ／ｇ（大兴安岭）

Research on early warning of electric power customers' credit risk based on SVM

Aiming at the deception phenomena in the electric power market that disorder the power trading, the early warning problem of power users&#39; credit risk in the power market was studied. To solve the problem, an early warning model based on SVM (Support Vector Machine) was purposed. First the evaluation criteria system and grading standard were discussed in detail. Secondly the early warning model based on SVM was built and the optimization of parameters was analyzed. Finally the data of Liaoning Electric Power Co., Ltd., from 2013 to 2016 is chosen as the sample data for verifying and simulating the early-warming model of power customers&#39; credit risk. The results showed the effectiveness of the proposed method.</p
