限期治理制度探析
,胡 
湖南工业大学学报(社会科学版) , 2009,
Abstract: 限期治理制度在减轻或消除我国的污染源、改善我国的环境质量状况起到了积极地作用 ,然而该制度的不足与缺陷也凸显出来。各级政府应该协助环境保护部门行使限期治理权 ,并统一执法标准 ,强化治理法律责任 ,完善其行政救济制 ,加强执法力度。

Advances in Analytical Chemistry (AAC) , 2015, DOI: 10.12677/AAC.2015.53005
Abstract:
采用Diamonsil-C18(1)色谱柱(250 mm × 4.6 mm, 5 μm),流动相乙腈-0.1%三氟乙酸水溶液,检测波长256 nm,结果10批不同来源的美洲大蠊药材标定了22个共有峰,其中指认了3个共有峰,其相似度大于0.950;与美洲大蠊药材对照指纹图谱比较,1批黑胸大蠊药材的相似度为0.990,但只有18个共有峰。本文建立的方法具有简便,重复性好,特征性强的特点,可用于美洲大蠊药材的鉴别与质量评价。
Taking Diamonsil C18(1) column (250 mm × 4.6 mm, 5 μm), with acetonitrile-0.1% trifluoroacetic acid as mobile phase, detection wavelength 256 nm, we got a result that there were 22 common peaks in batches of Periplaneta Americana, the peaks similarity was more than 0.950, three com-mon peaks were identified, the similarity of Periplaneta fulginosa was 0.990 by comparing with the control fingerprint, but there were 18 common peaks. The method is repeatable and feasible and can be suitable for the quality control of Periplaneta americana.
涉农贷款边际成本的测算及影响因素分析——基于湖南省87个县(市)农商行的经验数据

Abstract: 涉农业务边际成本过高是农村金融机构目标偏移的根本原因。依据2011-2014年湖南省87家县(市)农商行(含农信社)的经营数据,考量涉农贷款边际成本及影响因素。结果显示:微观方面,农商行的涉农贷款比重增加推高了涉农贷款的边际成本,提升资产中的贷款比重有助于降低涉农贷款边际成本,农商行的风险管理能力越强,涉农贷款的边际成本越低;宏观方面,县域金融发展水平的提升有益于降低涉农贷款的边际成本,城乡收入差距较大的县域,涉农贷款的边际成本也越高,提升县域融资市场的流动性有助于降低涉农贷款边际成本。
The high marginal cost of agricultural business is the primary cause of the mission drift of financial institutions. Based on the operating data of 87 rural commercial banks (including rural credit cooperatives) in Hunan Province from 2011 to 2014, the marginal cost of agricultural loans was estimated by Translog Production Function. Based on the results, quantitative analysis of the influencing factors of marginal cost on agricultural loan was carried out from macro and micro levels. On the micro level, the proportional increase of agricultural loans accelerates the increase of marginal cost, and the proportional increase of loans in the assets can help to reduce the marginal cost of agricultural loans. Besides, the better risk management ability rural commercial banks possess, the lower marginal cost of agricultural loans will be. On the macro level, the improvement of financial development level in the county is beneficial to reducing the marginal cost of agricultural loans, the higher of county income differences are, the higher marginal cost of agricultural loans will be, and the improvement of the liquidity of the county financing market can reduce the marginal cost of agricultural loan.

Abstract:
本文的目的是建立艾叶的HPLC指纹图谱鉴别方法,评价艾叶及其混淆品HPLC指纹图谱的相似性。采用RP-HPLC法,以Uitimate-C18 (250 mm × 4.6 mm, 5 μm)色谱柱为分析柱,流动相为乙腈-0.05%磷酸水,梯度洗脱,流速0.60 mL/min,290 nm波长下测定艾叶及其混淆品指纹图谱,并作相似度比较分析。结果建立了艾叶药材HPLC指纹图谱共有模式,有43个共有指纹峰被标定,且相似度较高,艾叶与其混淆品药材的HPLC指纹图谱有明显差异。实验结果表明HPLC指纹图谱具有方法简便,重复性好,特征性强的特点,可用于艾叶药材鉴别。
The purpose of this study was to establish HPLC fingerprint method for identification of argy wormwood leaf. Adopting RP-HPLC method, a uitimate-C18 (250 mm × 4.6 mm, 5 μm) column as the analytical column with mobile phase consisting of acetonitrile-0.05% phosphoric acid water, and gradient elution, under the flow rate of 0.60 mL/min at the wavelength of 290 nm, fingerprints of argy wormwood leaf and its adulterant were established, and then similarity comparison analysis was done. Finally we established the HPLC fingerprint’s common pattern of argy wormwood leaf, and 43 common peaks were calibrated, whose similarity was high. There was a significant difference of HPLC fingerprint between argy wormwood leaf and its adulterant. The results showed that HPLC fingerprint was simple and convenient, with good repeatability and strong characteristics, which could be used to identify argy wormwood leaf medicine.

张洪,王登峰,
心理学报 , 2006,
Abstract: ?为了验证外显与内隐的差序格局,研究者考察了最亲密的家人、恋人以及最亲密的好朋友的外显和内隐亲密程度的差异与联系,以及性别对亲密关系的影响。结果表明,三个目标对象的外显亲密程度之间存在差异,但内隐亲密程度之间不存在差异;外显和内隐亲密程度之间相关不显著;外显测量结果没有显著的性别差异,但在内隐测量中,男性比女性对恋人感觉更为亲密。研究者针对这些结果分别进行了讨论

文学社会学视域下的联邦德国早期小说
Novels in the Early Years of the Federal Republic of Germany from the Perspective of Literary Sociology
 [PDF]


World Literature Studies (WLS) , 2015, DOI: 10.12677/WLS.2015.32002
Abstract:
联邦德国50年代“经济奇迹”是德国历史上前所未有的经济高速发展时期。联邦德国50年代到60年代初期的社会批判小说不仅用现代的写作手法表达了一种美学上的反抗意识,而且还对五十年代“经济奇迹”社会进行了批判的反思,因此,这一时期的小说集中体现了“不顺从主义”的时代特征。
The Economic Wonder in the 1950s of the Federal Republic of Germany is the period that the eco-nomics has developed at the unprecedentedly high speed. The socially critical Novels from 1950s to the early 1960s in the Federal Republic of Germany have shown the rebellious character with the modern techniques of expression. In these novels, critical reflections have also been made on the Economic Wonder in the 1950s. Thus, the novels in this period demonstrate the character of nonconformism.
