明清小说在设置人物或编织情节时，常常像作对联一样，“一联”“一联”地让不同的叙事单元两两相对地组织起来。这种对联思维直观地体现在“回目对联”“章回尾联”和“章回插联”等三种不同类型对联的安置和运用上，成为小说构思的一个有机构成部分；但在设置人物、编织情节时，明清小说有时又脱略对联的外在形式，把不同的叙事单元像作对联一样两两相应地组织起来。

When designing characters or plots,the novels of Ming and Qing dynasties are usually like making an-tithetical couplets,couplet by couplet,and organizing various narrative units relatively. Such a antithetical thought is intuitively embodied in the application of the following three different types of couplets:“couplet of the chapter subtitles”,“tail couplet of the chapter”,and“inserted couplet of the chapter”,which become an organic composition of the conceptions of the novels;yet in the design of characters and plots,it sometimes breaks away from the external form of the couplets,and organizes various narrative units relatively like making antithetical cou-plets.

联合风险投资伙伴选择为组织间关系形成的研究提供了很好的研究背景。基于社会网络分析理论，通过构建控制选择分析模型，采用CVSource2000～2011年中国风险投资大样本数据，从参与者视角和投资机构间二元视角分别经验检验了风险投资机构网络位置、网络距离对联合伙伴选择的影响。研究发现，特征向量中心性对联合可能性有正向影响，网络距离对联合可能性有负向影响，表明风险投资机构网络中心性程度越高，投资机构间网络距离越小，联合的可能性越高。

Partner selection of venture capital syndication provides good research background for the formation of inter-organizational relationship.Based on the perspective of social network , this paper constructs a control analy-sis model and empirically tests the influence of network position and network distance on partner selection , using China venture capital data of CVSource from 2000 to 2011.The results show that eigenvector centrality has positive effect on syndication possibility.Network distance has a negative effect on syndication possibility.

怎样设计历史课的导入呢？巧用对联、诗歌、成语典故活跃课堂；利用歌曲歌谣导入新课；利用学语文课本上学过的课文导入新课；利用学生喜欢的电视剧导入新课；利用好现代化教学手段，再现历史情景。

How to design a history lesson? using poetic cou plet, poetry, allusion and active classroom; with songs and ballads into new courses;the Chinese school textbooks of the introduction of new courses;the TV series into students like new courses;make good use of modern teaching means, reproducing history scene.

由于采用区域控制误差的区域自动发电控制对联络线功率波动的控制彼此相对独立，可能无法通过各自自动发电控制的协调来快速控制联络线功率波动。针对此不足，基于分布式模型预测控制理论，研究了一种协调区域自动发电控制以抑制联络线功率波动的方法。该方法在建立区域互联系统的有功频率分布式预测控制模型的基础上，通过在预测控制周期内求解抑制联络线功率波动的纳什均衡控制解，以实现各区域自动发电控制的在线优化控制协调，利用模型预测控制的滚动优化达到对联络线功率波动的快速抑制。仿真结果表明该方法具有良好控制效果，验证了其有效性和可行性。

Due to comparatively independent control on tie-line power fluctuation by automatic generation control in regional control departure region,it may not realize fast control on tie-line power fluctuation by coordination of each automatic gen-eration control. Therefore, on the basis of distributed model prediction control theory, a kind of cooperative restrain method for tie-line power fluctuation by regional automatic generation control. This method was based on establishment of DMPC model for active power and frequency of regional interacted system. By means of solving in prediction control peri-od,it was able to restrain Nash equilibrium control of tie-line power fluctuation in order to realize online optimization con-trol coordination of each regional automatic generation control. Meanwhile,it was able to realize fast restrain on tie-line power fluctuation by rolling optimization of model prediction control. Simulation result indicated that this method was pro-vided with goo

针对故障后区间联络线功率振荡的问题,结合动态稳定分析理论提出采用电网支路功率分布特性法分析发电机状态量对联络线功率振荡的影响,并制定相应的控制措施。根据故障后系统的网络情况,分析各电源出力对联络线支路传输功率的影响程度。运用矩阵束分析法对故障后联络线功率进行模态分析,识别系统主要互联振荡模式幅值,并基于上述分析提出根据联络线支路功率综合贡献因子调整故障后各区域发电机出力的方法抑制互联区域振荡。采用CEPRI 8机36节点系统对该方法的有效性进行了仿真验证。仿真结果表明,所述控制方法显著地提升了系统阻尼,能够抑制故障后系统的区间功率振荡。

A branch power distribution method is proposed, combined with dynamic stability theory to analyze the tmpact ot generators on the power oscillation of tie line and corresponding controls to post-fault inter-area oscillations. The impact of generator output to transmission power of tie line is derived according to the network structure. Matrix pencil analysis is utilized to identify the modes of the power oscillations and to the amplitudes of oscillation modes. Based on these analysis, a post-fault control measure of rescheduling power generation based on general branch contribution factor （GBCF） is proposed to suppress the interval oscillations. The effectiveness of the proposed method is verified by the case study on CEPRI 8-generator 36-bus system. Test results show that the method can effectively enhance system damping and well damps post-fault inter-area power oscillations.
