农业企业创新技术采纳影响因素研究 ——基于TOE研究框架

采纳行为作为创新技术在组织中应用与实施的首要步骤，对于保证后者的效果十分重要。借助近年来在技术采纳领域被广泛应用的TOE研究框架，以影响中国农业企业创新技术采纳的各类因素为研究对象，从创新技术特性、企业组织特性和外部环境特性3个方面科学地归纳出技术的感知收益、成本、相容性和组织的集权化、正规化、企业规模、高层主管的创新特性以及外部环境中竞争压力、政府的推动作用、已采纳者的影响等10项指标，不仅丰富了农业技术采纳理论，而且对于农业企业技术创新实践也具有重大的指导价值。     

The Algorithm of Searching out the Least and Most Loops by Making Use of Direction Factor

Based upon the conception of the least loop,the most loop and direction factor presented by the author firstly,the algorithm of searching out the least and most loops has been designed.By building the adjoining matrix, confirming the start-point of searching,vectorizing the searching sides,calculating the direction factor of adjoining sides,we can search out the next side of the least loop or the most loop rapidly.With a valid searching side being confirmed at every searching and the searching scope being reduced by forming degenerate graph,the time compexity of the algorithm is much less. In the research of the automatic calculating system of construction quantities, the problem of houses partition and out-wall partition had been solved succesfully by utilizing this searching algorithm.

论功率因数监测系统设计现状及发展趋势

功率因数是供电系统的一项重要技术经济指标,用电设备在消耗有用功率的同时,还有大量的无用功率由电源送往负荷,功率因素反映的是用电设备在消耗一定的有功功率的同时所需要的无功功率。     

王家厂水库洪水实时预报方法及应用研究

考虑到流域降雨时空变化和流域地形、河道特征对流域产汇流的影响，应用新安江三水源产流模型、流域分散入流非线性汇流模型以及流域洪水实时预报校正模型，对王家厂流域洪水进行模拟，取得了较为满意的计算结果。     

黑龙江省农业经济增长方式转变的实证分析

在分析农业经济增长理论的基础上，运用算术指数法得到黑龙江省农业的全要素生产率。依据全要素生产率对黑龙江省农业改革以来的增长方式做了定量描述，从实证分析的角度，考察各种要素投入的增长及其对农业经济增长的贡献，衡量改革以来科技进步在黑龙江省农业生产中的状况和作用，进而描述黑龙江省农业经济增长方式的演进过程，为黑龙江省确定今后加快实现农业经济增长方式转变的政策和战略提供参考依据。     

Farmers' Attitudes to the Benefits and Barriers of Adopting Automation for Surface Irrigation on Dairy Farms in Australia

The study reports farmers' attitudes andperceptions towards the ``barriers' and ``benefits' of automaticirrigation systems. Factor analysis was used to identify perceived ``barriers' and ``benefits' andthe impact of these on farmers' priority to adopt automation wasexamined. Results suggest that farmers'attitudes, particularly with respect to ``cost' and``lifestyle' influenced the priority given to adopting automaticirrigation systems. The area under pasturecultivation was also an importantdeterminant in the farmers' priority foradopting automatic irrigation systems.     

农村污染缓流水体的修复研究

农村缓流水体是维系乡村生态平衡的重要组成部分, 水质污染已成为国内乡村缓流水体普遍现状。讨论了农村缓流水体的污染成因，并以水生植物大漂为水体修复主体，进行了大漂的水体修复特性的试验，讨论了在可控条件下用大漂对缓流污染水体进行修复治理的植物修复技术及大漂在水体修复中可能带来的生态风险及其防范。
