作为中国农村广泛存在的公共设施,农田灌溉系统的有效治理对实现农业可持续发展,促进农业农村现代化具有重要意义。本文运用定性比较分析(QCA)方法探讨了资源禀赋、制度规则、社会文化、社会资本4个因素对农田灌溉系统治理绩效的协同影响,挖掘了农田灌溉系统治理绩效差异化的组态路径。研究发现:①单个独立因素并不能形成高与非高水平的农田灌溉系统治理绩效。②高水平农田灌溉系统治理绩效可归为文化主导下制度与社会资本驱动型、资源主导下文化与社会资本驱动型、制度主导下社会文化驱动型3大类路径;非高水平农田灌溉系统治理绩效有资源-文化抑制型、资源-制度-社会资本抑制型2条路径。③高与非高水平农田灌溉系统治理绩效路径存在非对称关系,不能简单运用高绩效原因的反面解释非高绩效;对比发现社会文化和社会资本对农田灌溉系统治理高与非高绩效的影响更普遍。④高水平农田灌溉系统治理绩效路径中激励制度与约束制度存在替代关系;社会文化、制度规则对资源禀赋存在替代作用,是克服资源禀赋约束,提高治理绩效的可行手段。研究结果不仅为多因素联动影响农村公共事物治理的研究提供新分析思路,还可为促进乡村振兴提供重要理论与实践参考。

Radio frequencies explosive magnetic flux compression generator, an alternative to the use of capacitors as the load for helical magnetic flux compression generator, can provide a larger energy-to-volume ratio given than other conventional systems. As a kind of maneuverable device for generating and radiating electromagnetic pulse, radio frequencies explosive magnetic flux compression generator which bases on the theory magnetic field frozen effect is driven by explosive go off. Although this kind of device only adds a small capacitor to helical magnetic flux compression generator, but its characteristic has changed dramatically. The most important is that it has higher high-frequency component compared with helical magnetic flux compression generator means that it is easier to generate impulse radiation. Radio frequencies explosive magnetic flux compression generator has been found widespread uses as pulsed power sources for many fields. Also, due to their nature as a true one-time-use device with superior energy density, a large portion of applications is defense related. In this paper, the development of magnetic flux compression generator in recent decades is introduced. According to equivalent circuit model, we discussed the working principle of radio frequencies explosive magnetic flux compression generator. Its applications as pulsed weapons in military filed are shown. One of them is electromagnetic bomb, which is a mature technology as an electromagnetic weapon, uses an intense electromagnetic field to create a brief pulse of energy that affects electronic circuitry without harming humans or buildings. This kind of technology is discussed. Of course, the development of pulse weapon is introduced too.

Science China Chemistry 2004年第5期47卷 373-380页

作者： SUN Chengke1,2, ZHAO hongmei1 & li Zonghe1 1. Department of Chemistry, Beijing Normal University, Beijing 100875, China 2. Department of Chemistry, Qujing Normal College, Qujing 655000, China 1.

The thermal decomposition mechanisms of azoisobutyronitrile (AIBN) in the ground state have been investigated systematically. Based on the potential energy surfaces (PES) of various possible dissociation paths obtained using the semiempirical AM1 method with partial optimization, the density function theory B3LYP/6-311G* method was employed to optimize the geometric parameters of the reactants, the intermediates, the products and the transition states, which were further confirmed by the vibrational analysis. The obtained results show that the re- action process of the two-bond (three-body) simultaneous cleavage Me2(CN)C─ N=N─ C(CN)Me2? 2Me2(CN)C?+N2 is much more favorable than the reaction process of the two one- bond asynchronous cleavage Me2(CN)CN=N─C(CN)Me2 ? Me2(CN)CN=N?+ Me2(CN)C?? Me2(CN)C?+ N2. It was suggested that the electron shrinking effect of double bond (─N=N─) in AIBN and the stabilities of the Me2(CN)C?radical as well as N2 molecule are main factors of leading to the reaction proceeding in the former pathway. The calculation results were consistent with all the experimental facts.

为提高母线负荷预测的准确性,提出一种基于小波分解和支持向量机的母线负荷预测方法。该方法利用小波分解算法将目标负荷序列分解为若干个不同频率的子序列,通过分析各个序列的特征规律,构造不同的支持向量机模型对各分量分别进行预测,再将各分量预测值进行重构得到最终预测值。对某一区域内15条母线进行预测,采用平均日母线负荷准确率进行评价。与单独使用支持向量机方法相比,应用所提方法提高了962点的预测效果,占总预测点数的66.8%;全系统的准确率由93.5%提高到了95.1%。
