采用换电技术的电动出租车近年来发展迅速,但其利用效率、盈利能力和用户接受度尚不清晰。为了分析换电技术的用户接受度及其影响因素,该文基于技术接受模型,引入感知有用性、感知易用性、感知风险指标体系,构建换电技术接受度模型。采用问卷调查方法收集北京市纯电动出租车驾驶员的换电技术使用数据,分析换电技术接受度及其影响因素。结果表明:充换模式电动车、纯换模式电动车及内燃机汽车的技术接受度分值分别为3.80、3.37、4.29。作为充电技术的补充,换电技术能有效缓解里程焦虑,但目前换电出租车的技术接受度仍低于传统内燃机出租车,需着重提升里程利用率、续航稳定性、补能便利性、主观安全性和车辆经济性,以加快电动出租车的推广应用。

自20世纪60年代以来,宏观经济学的各个分支学科都越来越重视寻找宏观经济理论的微观基础。主流经济学认为,宏观经济理论必须建立在与新古典模型的根本特征相一致的微观经济基础之上;非主流经济学对传统意义上宏观经济学的微观经济基础之争持有很大的怀疑;后凯恩斯主义者认为,真正需要的是微观经济学的宏观经济基础;演化经济理论主张微观基础解释的是社会变迁。文章在对当今微观基础问题争论进行梳理的基础上对宏观经济学体系的内在形成机理和变化趋势进行了探索。

Journal of Medical Colleges of PLA(China) 2010年第4期25卷 212-219页

作者： Liu Yamin han Hui Qin hao Yu Li Zhang Min Feng Jun Department of Peripheral Vessels First Affiliated Hospital Xi 'an Jiaotong University Xi 'an 710061 China

Objective： To explore the efficacy of interventional therapy for chronic atherosclerotic occlusive disease of the lower extremity. Methods： Fifty-six cases of simple atherosclerotic occlusive disease of lower extremity were divided into 3 types according to the location of occhision, including 17 cases of abdominal aorta-iliac artery, 18 cases of iliac-femoral artery, and 21 cases of inferior popliteal artery. Catheter and guide wire combined with blunt dissection and subtle banding were used to dredge the occluded vessels, and stents were implanted when interlayer appeared. Results： After the treatment, 46 cases of occlusion were dredged （82.1%）, 6 cases remained occluded with the same symptoms （10.7%）, and 4 cases had severer symptoms （7.1%）. Among the 46 successful cases, there were 16 cases of abdominal aorta-iliac artery （94.1%）, 16 cases of iliac-femoral artery （88.9%） and 14 cases of inferior popliteal artery, artery （66.6%）. There was no statistical difference between the abdominal aorta-iliac artery cases and iliac-femoral artery cases （P〉0.05）, but there was statistical difference between these two types and the inferior popliteal artery cases （P〈0.05）. In the successful cases, 9 cases of abdominal aorta-iliac artery （52.9%）, 10 cases of iliac-femoral artery （55.5%） and 10 cases of inferior popliteal artery （33.3%） had 5-10 cm of occlusion, with no statistical difference between the first two types （P〉0.05）, but with statistical difference between the first two types and the third type （P〈0.05）. Compared with the 14 dredged cases （71.4%）, the 7 cases （33.3%） of inferior popliteal artery cases had richer compensatory circulation （P〈0.05）. Conclusion： It＇s safe and effective to treat simple atherosclerotic occlusive disease of the lower extremity with interventional therapy. The location and length of occlusion and the abundance of compensatory circulation had effect on the therapy.

从农林特产资源管理的经济学价值定位、农林特产资源价值理论构建和农林特产资源价值构成3个方面阐述了农林特产资源的价值。认为:我国农林特产资源存在稀缺性问题,国家的介入和干预,对农林特产资源实行管理是必要的。用马克思劳动价值论和修正后的边际效用价值论的结合完整地说明了农林特产资源本身效用和人类的劳动投入都是农林特产资源的价值基础,合理地解释了特产资源的价值。农林特产资源价值包括经济价值、社会价值和生态价值,量化农林特产资源的价值是资源经济学研究的重点。
