昆虫学报 , 1988,
Abstract: 焦艺夜蛾HyssiaadustaDraudt是新发现的马尾松严重害虫.一年1代,以蛹在土中越冬,翌年3月初羽化,产卵于松针上,3月中旬孵化.幼虫食叶,一般7龄,幼虫期49—77天,蛹期约250天.前一年冬季和当年早春的干旱是该虫于当年大发生的主要因素.可应用741烟剂或白僵菌粉炮防治.大星步(虫甲)CalosomamaximowicziMorawiz是主要天敌,对害虫大发生有一定抑制作用.

纤维饼干的研制与应用

食品科学 , 1985,
Abstract: ?近年来,在西方国家中,糖尿病、冠心病、结肠癌等的发病率不断升高。美国患糖尿病率高达5%。我国于1980年对14个省市的30万人口进行调查,发现患病率为0.61%,而且还有区域性上升的趋势。对流行病学进行研究认为,低纤维淀粉食物对易感基因型人群是一种致糖尿病因素,而高纤维、高醣饮食,对糖尿病却能有防护作用。
城市和农村电子商务物流服务质量评价比较研究
Urban and Rural E-Commerce Logistics Service Quality Evaluation
 [PDF]


Service Science and Management (SSEM) , 2016, DOI: 10.12677/SSEM.2016.53009
Abstract:
近几年,农村电商物流越来越热门,各大电商企业争相开拓农村市场,但农村地区电商物流服务有自身的特殊性,电商企业用于评价城市电商物流服务质量的一套指标体系,对于农村来说是不适用的,本文根据在国内外相关文献研究基础上结合农村电商物流的特点,构建针对农村地区的物流服务质量指标体系,并对城市电商物流服务质量指标体系和农村电商物流服务质量指标体系中的维度和指标分别进行比较和分析,对于电商及物流企业更好地在农村地区的发展,提高物流服务质量水平有重要的意义。
In recent years, with rural e-commerce logistics becoming more and more popular, the main e- commerce enterprises begin to develop the rural market, but due to the particularity of rural e-commerce logistics service, the index system evaluating urban e-commerce logistics service quality is not suitable for rural areas. According to the related literatures at home and abroad, combined with the characteristics of rural e-commerce logistics, this paper built a logistics service quality index system for rural areas, and compared and analyzed the dimensions and indicators of e-commerce logistics service quality index system in urban and rural areas respectively. These have important significances for better developing e-commerce and logistics enterprises in rural areas, and improving the level of logistics service quality.

情绪智力对个体情绪调节的影响
Effects of the Emotional Intelligence on Individual Emotion Regulation

Abstract: 情绪智力对个体情绪调节起着重要的作用。采用情绪智力测评量表(EIS)测量370名大学生的情绪智力,从中随机抽取得分较高和较低两个水平的学生各20名作为情绪智力高分组和低分组。通过序列递减任务诱发负性情绪,比较两组被试在负性情绪的情境下的情绪体验差异。结果发现,情绪智力水平高分组在负性情绪诱发情境下,会自动化地调节和控制自己的情绪;而情绪智力水平较低的个体,则未对自己的情绪进行自动化的控制和调节。
Emotional intelligence plays an important role in individual emotion regulation. A sample of 370 college students was tested by Emotional Intelligence Scale. 20 students of higher scores and 20 students of lower scores from this sample were randomly selected to do the next test. Serial Subtraction Task which can elicit negative emotion was used to test the effects of the Emotional Intelligence on individual emotion regulation. The results showed that the students with high Emotional Intelligence could automatically control their emotion in the negative emotion-eliciting context, but the students with low Emotional Intelligence would not control their emotion in this kind of context.
25年生马尾松生长和木材基本密度家系变异与选择

林业科学研究 , 2010,
Abstract: 以福建省华安县西陂林场的25年生来自省内不同产地的46个马尾松自由授粉家系试验林为试材,研究了达主伐年龄时马尾松生长、干形和木材基本密度的家系差异以及性状间的相关性,并依据不同培育目标选择优良家系。结果表明,马尾松生长、树干圆满度和木材基本密度皆存在显著的家系差异,其中生长和树干通直度变异相对较大,而树干圆满度和木材基本密度变异较小,变异系数在10%以下。生长和干形性状受到弱至中度的家系遗传控制,家系遗传力为0.23 0.46;木材密度受到的遗传控制相对较强,家系遗传力为0.46。性状遗传相关分析结果显示,选择速生种源可同时改良树干圆满度,但对树干通直度和木材基本密度影响不大。根据不同用材对材质材性要求,选出24个纸浆纤维材优良家系和6个锯材优良家系,平均木材干物质量和胸径生长皆为对照的1.16倍。
抗病湿地松、火炬松家系评价及优良家系选择

南京林业大学学报(自然科学版) , 2010, DOI: 10.3969/j.jssn.1000-2006.2010.02.011
Abstract: 为了选择适合福建省南部地区生产推广的国外松优良家系,评价了福建华安西陂林场自美国引种的抗病湿地松、火炬松基因库中各家系的生长性状。结果表明:引种的抗病湿地松、火炬松在福建省生长良好,参试家系8年生时湿地松平均树高、胸径、冠幅分别为5.95m、11.1cm和3.30m,火炬松平均树高、胸径、冠幅分别为5.97m、10.7cm和3.66m。抗病湿地松、火炬松的树高、胸径、冠幅生长性状在家系间存在真正的遗传差异,这种差异受到中度或者中偏强度遗传控制。以树高和胸径遗传增益为主要指标,按10%入选率,选择出m39×8等5个湿地松优良家系,树高、胸径、冠幅平均值分别为8.69m、13.9cm、4.48m,分别比群体平均值高46.05%、25.23%和35.76%,3性状平均遗传增益分别为16.63%、11.90%和17.22%;选择出(5-142)×(5-148)等5个优良火炬松家系,树高、胸径、冠幅平均值分别为7.69m、13.8cm、4.95m,分别比群体平均值高28.81%、28.97%和35.25%,3个性状平均遗传增益分别为17?17%、17.02%和20.17%。依据此选择效果,这些国外松优良家系可在福建南部地区推广应用。

Abstract: 针对目前实验项目管理存在缺乏实时质量监控的问题,构建了基于任务分解的实验项目管理平台。该平台采用了目前较为成熟稳定的J2EE框架及JSP(Java server pages)技术,数据库采用了MYSQL,平台运行环境基于TomcatJDK6。论文给出了平台的整体框架和主要功能模块的设计,最后从任务管理模块介绍了平台的关键实现。该平台现已投入使用,完善了实验教学质量保障体系。
Traditional experiment management model is lack of real-time quality control, in order to improve our current platform, a new experiment management platform has been established. Using the J2EE framework, the platform is constructed with technology of JSP (Java server pages) in conjunction with MYSQL database and its running environment adopts the JDK6 combining the Tomcat. In this paper, the overall frame and design of the major functional module is given as well as the description of the architecture implementation technology of the task management. The platform has been put into use with good performance, which improves the quality guarantee system for experiment teaching.
市场、资源、环境
贾绍,孟向
地理科学进展 , 1996,
Abstract: 正统经济学家认为,如果建立了适当的环境货物市场,政府、公司和团体剧烈争斗的环境危害和资源利用问题就可解决。本文认为,市场通常不是解决环境争议的适宜机制:环境争议的主要问题是确定其效应而不是分配它们;当未来的折现率为正时,社会需要不同于理性的个人决策之和;市场忽视平等。而且,关于可持续性的限制似乎是定量的而不是定性的——例如依赖于资源发现的数量,或者每一元投资改善环境质量的比率。再次,中心的问题关心的是数据而不是分配成本和效益的方式。采用市场机制的这些困难暗示着法制系统可能是更好的调
