摘要：针对传统柔性作业车间调度问题,将机器动态预维护与绿色调度进行联合优化,以最小化最大完工时间、总碳排放量、总成本为优化目标建立集成优化模型。提出了一种改进的NSGA-I算法用于求解该模型,采用基于工序、机器和预维护的三层编码方式,设计了考虑工序分配、机器选择以及机器预维护策略的同步解码方案;改进了精英保留策略,设计了随着代数变化的自适应交又变异函数以及基于邻域搜索的变异算子。实验验证了改进算法在求解不同规模调度问题的有效性,所提的动态预维护策略较其他维护策略能更有效地求解预维护与柔性作业车间绿色调度协同优化问题。

摘要：The paper presents a knowledge-based engineering （KBE） approach for ship node components design. In the ship design process, many design tasks need design experiences to support. Howev- er, a ship design process is a complicated process with many simultaneously repetitive and time-con- suming activities. In this research, the method combines KBE with Tribon system＇s built-in devel- opment language tools of Vitesse, captures and applies design knowledge for achieving standard com- ponents intelligent design modeling. A case study and industry implementation illustrate the feasibili- ty of the proposed methodology. The KBE technique can provide not only proper references, sug- gests and supports but also knowledge integrated in the ship structure design. Especially, these rules related to the design can avoid lots of design mistakes. During the ship design stage, getting more precise and better designs will not only reduce the time of rework and wasting resources but also shorten the construction time_ imnrov~ clilnl;hz ~nA nrnf;t

摘要：电容器蓄电池在储能特性、充放电速度和功率密度等方面存在差异,使得电力信号的单位存储量较低,导致电量传输稳定性较差。为此,提出基于能量转换模型的电容器蓄电池混合储能方法。按照能量转换模型,求解电容器能量输出特性方程,联合能量转换参数,跟踪电容器功率。分析电容器蓄电池储能特性,通过双向DC/DC变换器建模,确定单位储能量,完成基于能量转换模型的电容器蓄电池混合储能方法的设计。实验结果表明,该方法可将电能信号的输出功率控制在3.5~4.8 kW的数值范围之内,不会因电量信号的非平稳传输而造成电容器设备实时储能能力下降,能够提升电容器蓄电池中电力信号的单位存储量。

摘要：A similitude method to model the tip clearance flow in a high-speed compressor with a low-speed model is presented in this *** first step of this method is the derivation of similarity criteria for tip clearance flow,on the basis of an inviscid model of tip clearance *** aerodynamic parameters needed for the model design are then obtained from a numerical simulation of the target high-speed compressor *** to the aerodynamic and geometric parameters of the target compressor rotor,a large-scale low-speed rotor blade is designed with an inverse blade design *** order to validate the similitude method,the features of tip clearance flow in the low-speed model compressor are compared with the ones in the high-speed compressor at both design and small flow rate *** is found that not only the trajectory of the tip leakage vortex but also the interface between the tip leakage flow and the incoming main flow in the high-speed compressor match well with that of its low speed *** results validate the effectiveness of the similitude method for the tip clearance flow proposed in this paper.

摘要：爆破振动是影响露天矿边坡稳定的重要因素之一。通常采用预裂爆破控制爆破振动效应,降低爆破振动对边坡稳定性的影响。预裂缝宽度是影响降振效果的关键指标。基于预裂缝降振原理,研究预裂缝宽度对优化预裂爆破设计、提高降振效果与保障矿山安全生产具有重要意义。为了研究预裂缝宽度对降振效果的影响规律,结合爆破地震波构成及传递理论,分析了预裂缝对爆破地震波的降振原理,利用数值模拟验证了预裂缝宽度对爆破地震波传递和衰减规律的影响。采用物理相似模拟与数值模拟实验,以质点的峰值振速为判据,针对不同预裂缝宽度时的降振效果进行了定量分析。结果表明:预裂缝宽度由2 cm增加到4 cm时,峰值振速衰减曲线下降趋势急剧,各测点监测的减振率显著增加;随后,预裂缝宽度继续增加到5 cm,峰值振速衰减曲线下降趋势变得平缓,减振率平均增幅为3.25%。随着测点与预裂缝距离的增加,振降效果也随之增加,但增幅会逐渐变得缓和,减振率总体呈现先急、后缓的趋势。

摘要：近年来,动漫与戏剧的结合愈演愈烈。不少媒体为了挽救日渐衰落的传统文化,将传统艺术与动漫艺术相嫁接,希图以此来博得更广泛的群众关注。而动漫作为朝阳产业,在当今中国也并没有表现出原本该有的生机和活力。若想通过戏剧与动漫的联姻,使两者都焕发出新的面貌,必不能使它们简单叠加,而是要在相互融合的基础上进行再创造。
