图书馆与终身学习

终身教育是学校教育在时间、空间及其职能上的延伸。终身学习是当今社会发展的必然趋势。图书馆是知识的宝库、信息交流的中心，图书馆向每个社会成员开放，能满足任何受教育者的需求，为社会、为受教育者实现终身学习提供最佳的学习条件，满足社会成员获取文献信息及进行终身学习的需要。     

THE SYSTEMATIC DYNAMIC EMULATION ON THE AGRICULTURAL DEVELOPMENT ON THE LOESS PLATEAU

<正> The Loess Plateau, covered with thick loess, lies in the middle reaches of the YellowRiver to the west of the Taihangshan Mountains, east of the Wuqiao Mountains south ofYinshan Mountains and north of the Qinling Mountains with a total area of 56×10~4km~2.The plateau is 1000--2500m above sea level and has loess as thick as 100--200 metres, be-

Fluctuations in European eel (Anguilla anguilla) recruitment resulting from environmental changes in the Sargasso Sea

European eel decline is now widely observed and involves a large number of factors such as overfishing, pollution, habitat loss, dam construction, river obstruction, parasitism and environmental changes. In the present study, we analyzed the influence of environmental conditions in the Sargasso Sea and Atlantic ocean circulation on European glass eel recruitment success. Over a recent 11‐yr period, we showed a strong positive correlation between an original index of glass eel recruitment and primary production (PP) in eel spawning area. Moreover, PP was negatively correlated with temperature in the Sargasso Sea. Therefore, we used sea temperature as an inverse proxy of marine production. A close negative relationship has been found over the last four decades between long‐term fluctuations in recruitment and in sea temperature. These findings were reinforced by the detection of a regime shift in sea temperature that preceded the start of the decline in glass eel recruitment in the early 1980s. By contrast, variations in integrative indices measuring ocean circulation, i.e. latitude and strength of the Gulf Stream, did not seem to explain variations in glass eel recruitment. Our results support the hypothesis of a strong bottom‐up control of leptocephali survival and growth by PP in the Sargasso Sea on short and long time scales. We argue that sea warming in the eel spawning area since the early 1980s has modified marine production and eventually affected the survival rate of European eels at early life stages.     

南阳黄牛进行人培牛黄技术试验

通过外科手术的方法,将专用网架、育黄菌种等植入南阳黄牛胆囊内,达到快速成黄、提高产量的目的;育黄术对南阳黄牛的生长发育、繁殖和使役等无明显影响,育黄期12、18、24、36个月每头平均产黄量为6.44、10.93、16.72、28.32g,其质量与天然牛黄相似;统计分析表明:牛黄产量与育黄期之间有强的正相关,每头平均产黄量对育黄期的回归方程为:y1=-2.27 0.7819x,每头月均产黄量对育黄期的回归方程为:y2=0.4074 0.011x;据此可进行产黄量的理论推算和预测。

苦丁茶大叶冬青的降脂作用研究

以不同剂量的苦丁茶大叶冬青提取液喂饲高脂模型大鼠,采用Transansio全自动生化分析仪测定正常及各高脂模型组大鼠的血清脂质含量。结果苦丁茶和月见草油均能显著降低高脂血症大鼠的血清TC、TG指标（P<0.05）,对HDL-C、LDL-C、 AI、R-CHR有一定的调节作用。证明苦丁茶大叶冬青有显著的降脂效果,对抗动脉粥样硬化有一定的预防作用。     

基于心理契约的网络消费者重复购买意向实证研究

网络营销情景下,消费者在进行购买决策时对心理和情感层面的感知依存度很高,通过对消费者交易心理契约、关系心理契约与感知风险、网络信息以及重复购买行为之间的关系假设,并对这些变量进行分别测量的关系验证后发现,关系心理契约主要通过影响消费者的网络信任来影响重复购买意向,而交易心理契约尽管同样主要是通过网络信任来影响重复购买行为意向,但其对网络信任的影响度要低于关系心理契约。从这一点来看,加强关系营销是提高网络营销效果的重要途径。
