风险资本与智力资本协同条件分析与效应检验
马宁, 太华,新龙
中国管理科学 , 2015,
Abstract: ?运用协同学的原理与方法对风险资本和智力资本的协同条件及变化进行了定性分析,并对二者的协同效应进行了基于风险投资持股比例的门槛效应检验。结果显示:(1)协同效应下智力资本对企业绩效显著地存在“单门槛效应”,风险投资持股比例可以作为判断风险资本与智力资本发生协同作用的条件;(2)当风险投资持股比例高于门槛值时,智力资本会加速提升企业的资产利用效率和市场价值,但这一现象在企业人力资本增值效率方面的表现并不理想。研究结论表明智力资本的增值作用仍有提升空间,但协同效应的发挥需要满足一定的条件,客观上要求创业企业要有针对性的引进风险投资,以便改革、增强并利用智力资本。
智力资本协同风险资本的系统建模及效应检验
太华,马宁,新龙
系统工程理论与实践 , 2014,
Abstract: ?根据哈肯的协同学原理和方法,对智力资本和风险资本的协同系统建模并进行了参数变量和协同变化定性分析,推导了二者的自组织运动方程,指出风险资本的参与会引起创业企业智力资本水平的显著变化,进而会影响企业整体绩效.后根据vaic模型(valueaddedintellectualcoefficientmodel)进行多变量面板回归实证检验,研究发现:有风险资本参与时智力资本对企业绩效影响较大,二者的协同效应会提升企业的资产利用效率,增加股东权益回报,以及提高企业的持续增长能力.但该绩效影响主要表现在有形资本方面,即物质资本增值效率,而无形资本如人力资本和结构资本增值效率并不显著.该研究表明创业企业还需加强风险资本利用效率,并要有针对性地改革和增强自身智力资本形成.
烟梗原料4种常规化学组分的近红外快速分析
袁而文,新龙,赵东辉
红外技术 , 2015, DOI: 10.11846/j.issn.1001_8891.201501017
Abstract: 为了研究近红外光谱技术预测再造烟叶原料烟梗中烟碱(Nic)、总糖(Ts)、还原糖(Rs)及氯(Cl)含量的可行性,以上海薄片S、广东薄片烟梗原料及混梗原料等130个样品的近红外光谱结合偏最小二乘法建立以上4种常规化学组分的近红外漫反射模型,并对模型的预测效果、稳定性及准确性进行评估。结果表明:①烟碱、总糖、还原糖及氯模型的校正均方差(RMSEC)与预测均方差(RMSEP)接近且均较小,模型预测的相关系数(Corr.Coeff.)均在0.97以上。烟碱、总糖、还原糖及氯预测平均相对方差分别为3.47%、1.23%、1.31%和2.34%。②模型通过检验,发现模型的RMSEP/RMSEC接近1且其RPD值均大于3,表明近红外定量分析结果准确、可靠与流动分析法无显著性差异。

- , 2016, DOI: 10.3969/j.issn.1673-1689.2016.07.015
Abstract: 对低次烟叶分别进行高温高水分好氧和厌氧发酵,烘干,陈化一周后制备提取液,应用顶空固相微萃取气质联用HS-SPME-GC-MS对不同提取液中的挥发性致香成分进行分析比较,并将浓缩后提取液涂布于片基上进行评吸。结果表明,经高温高水分好氧和厌氧发酵低次烟叶制备的提取液中挥发性致香成分种类分别为52种、51种,合计质量浓度分别为43.38 μg/mL、40.16 μg/mL。而未经发酵低次烟叶制备的提取液中挥发性致香成分种类为34种,合计质量浓度为23.61 μg/mL;低次烟叶经固态发酵后所得提取液中酸类、酯类、酮类、醇类、醛类、杂环类等致香成分均有不同程度的增加,増香除杂效果明显,能够改善烟草薄片的吸食品质。
The fermented extracts were prepared from discarded tobacco leaves using aerobic and anaerobic fermentation with high temperature and high moisture,followed by one-week aging after drying. The volatile components in the extracts were comparatively analyzed by headspace solid-phase micro-extraction(HS-SPME) associated with capillary gas chromatography-mass spectrometry(GC-MS). The concentrated extracts were coated on film base for smoking quality analysis. There were totally 52 volatile aroma components detected in the aerobic fermentation tobacco extracts with a concentration of 43.38 μg/mL,and for extracts from anaerobic fermentation,there were 51 kinds of 40.16 μg/mL. For the control sample without fermentation,there were 34 components with concentration of 23.61 μg/mL. The contents of acids,esters,ketones,aldehydes,heterocycles were increased at different levels after fermentation. The significant effect of aroma enhancement and impurities removal confirmed that the smoking quality could be improved by fermentation treatments
中国十倍体割手密资源的表型相关性及遗传多样性
新龙
湖南农业大学学报(自然科学版) , 2012,
Abstract: 为有效评价和利用十倍体割手密资源,挖掘其优异性状,选取中国6个省9个地区的171份十倍体割手密资源,针对8个质量性状指标和8个数量性状指标,对其多样性指数、变异系数、数量性状间的相关性、数量性状与纬度和海拔的相关性进行研究。表型相关性分析结果表明:十倍体割手密资源质量性状的Shannon–Wiener多样性指数整体偏低,采自滇中地区的多样性指数(0.636 6)最高,而采自滇西北地区的多样性指数(0.335 8)最低;数量性状的遗传变异较丰富,变异系数最大的为滇西南地区的资源(33.06%),最小的为贵州的资源(22.12%);产量性状与海拔和纬度呈负相关,糖分性状与海拔呈负相关,与纬度呈正相关,纤维分仅与海拔呈正相关;产量性状之间和糖分性状之间均呈正相关。遗传结构分析结果表明:表型性状的遗传变异主要来自于采集地区内部,采集地区之间有明显的基因交流(基因流值Nm>3),遗传分化不明显。聚类分析结果表明:表型性状与采集地的地势有一定关系,高地势的滇东北地区和滇西北地区聚为一个小类群,低地势的滇东南、滇西南、川东南、广东地区聚为一个大类群。

园艺学报 , 2006,
Abstract: 初步探索了山茶花红色素的提取条件和理化性质,结果表明,用料液比1∶10(g/ml)、ph1(10%盐酸调)的95%乙醇作提取剂,在80℃恒温提取6h,提取效率较好。山茶花红色素属花色素苷类,ph值对色素影响明显,在酸性条件下色泽具有热稳定性。光照能加快色素降解,但与紫外光无关。金属离子na+、ca2+、a13+、cu2+、zn2+对色泽无影响,fe3+、pb2+有不良影响。色素的抗氧化能力较差,耐还原性较好。蔗糖、葡葡糖和盐等添加剂对色素无影响。

基于BDF的无约束优化方法的收敛性分析
新龙
计算数学 , 2003,
Abstract: 1.介绍在上个世纪的七十年代末、八十年代初,基于常微分方程的优化方法或者说同伦方法是一类与拟牛顿法和共轭梯度法等我们所熟知的优化方法相竞争的重要方法[1-6,8,13,14,16].由于这类方法只是简单地利用现成的数值求解常微分方程的软件包,如CVODE[7]、LSODE[12],对同伦方程(一般是一个常微分方程的初值问题)进行计算,除了一些特殊的病态问题
农村集体成员代表诉讼的法理逻辑与制度构造
新龙
南京农业大学学报(社会科学版) , 2018,
Abstract: 集体成员代表诉讼制度对保护农村集体财产具有重要价值。农村集体作为特别法人具有团体人格,代表诉讼之价值即是纠正团体人格异化,二者在团体法逻辑上实质契合。由于立法不完备和司法的弱救济,侵犯集体财产权的现象频发且普遍游离于司法审查之外,亟需赋予集体成员提起代表诉讼的权利。但是,在集体成员代表诉讼中,原本集受害人、代言人和受益人"三位一体"的原告构造发生解体,集体成员陷入成本收益严重失衡的激励困境。为此,农村集体成员代表诉讼的法律构造应以增加集体成员的诉讼激励为旨归,创设各种具体规则提高原告的预期净收益,激励集体成员积极起诉以实现保护集体财产权益的立法目标。
Constructing the system of the rural collective members’ Representative Action is of great value for protecting the rural collective assets. In the logic of the group law,the rural collective organization, which has the group personality, corresponds substantially to the legal value of Representative Action,which is to correct the alienation of the group personality. Because of the imperfection of the legislation and the weak relief of judicature, the phenomenon of infringing the rural collective assets happens frequently and is generally outside Judicial Review. It is urgent to endue the rural collective members with the right of beginning Representative Action. However in Representative Action, the plaintiff’s structure of "Trinity", which involves the victim, the spokesman and the beneficiary, has disintegrated, and the rural collective members have been trapped in a serious imbalance of Cost and Profit. So, the legal structure of the rural collective members’ Representative Action should be aimed at increasing the stimulation on the action of the rural collective members, creating specific rules to improve the expected income of the plaintiff, and encouraging the rural group members to sue actively,to eventually achieve the legislative goal of protecting the rural collective assets
PPP模式与众筹融资有效融合问题探讨
The Discussion of the Problem from the Effective Fusion between PPP Mode and Crowdfounding
 [PDF]

郑再杰, 陈婷,新龙
Modern Management (MM) , 2016, DOI: 10.12677/MM.2016.61005
Abstract:
自从2013年以来,PPP模式在基础设施和公共服务类项目中得到广泛运用。由于PPP项目具有资本投入大、投资周期长、回报慢等特点,PPP项目的融资安排是个难题。众筹融资作为一种新型高效的融资模式正在快速发展,本文对众筹融资模式运用到PPP融资安排中进行了可行性分析,同时对可能遇到的问题与挑战进行探讨,并在这基础上提出相关建议。
Since 2013, the PPP model in infrastructure and public service class is widely used in the project. Because the PPP project has huge the characteristics of capital investment, long investment cycle, and slow return, PPP project financing is a difficult problem. The Crowdfunding as a new and efficient financing mode is rapid development. In this paper, we analysed the feasibility of crowdfunding financing mode applying to PPP financing arrangements, at the same time discussed the possible problem and challenges, and put forward related suggestions on this basis.
