摘要：为研究发生在竖井结构近区浅埋爆炸成坑效应,依托浙江大学ZJU-400土工离心机开展了3组竖井结构受侧向浅埋爆炸作用离心模型试验,通过对砂土抛掷成坑过程、结构内壁加速度和外壁应变响应分析,得出以下主要结论:相比自由场中爆炸,发生在竖井结构近区的浅埋爆炸,若最大瞬态爆腔未与结构发生接触,结构物的存在将对爆腔膨胀产生约束作用并造成弹坑体积发生缩减;若瞬态爆腔膨胀至竖井边壁,由于爆轰气体与竖井间的碰撞挤压作用,表观弹坑将呈现出不对称性且弹坑体积也将得到增大;随着爆源至结构距离的增加或爆源埋深的减小,结构对弹坑形成的影响逐渐减弱。爆炸成坑对结构动态响应影响显著,相比埋深较大的结构部分,接近或暴露于弹坑范围内的结构部分在受到爆炸冲击时振动响应更为强烈,同时也易产生更大的变形损伤。本研究可为竖井结构的抗爆设计提供依据,也可为后续此类结构在爆炸荷载冲击下的相关性能指标和毁伤效应研究提供参考。

摘要："画"与"写",是两种绘画境界和形式语汇的融汇。从比较美学视域看,"画"与"写"折射的是中西绘画不同的形式语汇与艺术精神。"写"体现了中国绘画的写意精神,"画"体现了西方绘画的求真精神。二者互参互补,有助于当代画家弘扬传统文化,吸收外来文化,探索出自己的创作新路。

摘要：Aiming at the deficiencies of analysis capacity from different levels and fuzzy treating method in product function modeling of conceptual design, the theory of quotient space and universal triple I fuzzy reasoning method are introduced, and then the function modeling algorithm based on the universal triple I fuzzy reasoning method is proposed. Firstly, the product function granular model based on the quotient space theory is built, with its function granular representation and computing rules defined at the same time. Secondly, in order to quickly achieve function granular model from function requirement, the function modeling method based on universal triple I fuzzy reasoning is put forward. Within the fuzzy reasoning of universal triple I method, the small-distance-activating method is proposed as the kernel of fuzzy reasoning; how to change function requirements to fuzzy ones, fuzzy computing methods, and strategy of fuzzy reasoning are respectively investigated as well; the function modeling algorithm based on the universal triple I fuzzy reasoning method is achieved. Lastly, the validity of the function granular model and function modeling algorithm is validated. Through our method, the reasonable function granular model can be quickly achieved from function requirements, and the fuzzy character of conceptual design can be well handled, which greatly improves conceptual design.

摘要：提出并建立了混成电力控制系统(HybridPowerControlSystem,HPCS)概念、理论架构及其方法论,可以认为这是电力系统中一门新学科分支的诞生。为了有助于理解该学科分支的理论和方法并进而加以应用,特以混成自动电压控制(HAVC)为例进行了具体的阐述。在HAVC系统中,我们建立了混杂分层电压控制模型,采用离散事件作为驱动主体,并可以实现复合指标调控。该理论和方法的应用使长期以来电力系统运行调度中品质-稳定-经济三重优化的“梦想”成为现实。应该指出本文阐明的HAVC系统设计理念和方法亦实用于大电力系统的混成自动调频(HAGC)和其他具有混成结构的系统,如军事实战指挥系统、复杂的大规模制造加工系统和某些过程优化控制系统等。

摘要：社交网络的研究应用领域广泛,大多数的研究主要关注于社交网络结构中节点和链接的变化,研究角度较为单一.而群组协作关系在社交网络中较为普遍,为更好地探索群组协作过程中群组级别网络结构的演变,首先将组级任务添加到用于图可视化的任务分类中,针对协作关系网络的特性,设置一个适用于群组协作关系分析的任务分类法,根据此任务分类法设置探究群组协作需完成的任务;然后设计相关可视化视图,以更直观的方式展示群组之间以及群组内部协作关系的特征以及随时间推进的演变模式;最后在学术协作文献数据集上进行具体案例分析,通过用户评估实验,采用李克特量表对调查问卷进行分析,验证了设计可视化视图的有效性和实用性,可为社交网络关系分析人员提供群组协作的可视化分析方法,更便于对群组协作网络关系的进一步探究和应用.

摘要：图可视化中边捆绑算法可用来减少图的视觉混乱并增强图的高等级结构显示.针对一般边捆绑过程中,因属于不同结构的边可能相互捆绑而降低捆绑结果可读性的问题,提出一种基于图的内容重要度的边捆绑算法.首先使用关联边提取和关联度估值算法,从包含大量的点、线连接的图中提取出可反映图的高等级结构的边簇信息,然后使用改进的力引导捆边算法对边簇进行捆绑,达到在减少图的视觉混乱同时将重要性较高的连接捆绑到独立的边簇中的目的.实验结果表明,该算法可以有效地降低不同结构边簇在边捆绑中的相互影响,从而保证属于不同结构的重要连接可以得到恰当的捆绑进而使得图中高等级结构的显示更清晰.
