摘要：In the present work,a principle of equipartition of entransy dissipation(EoED) for heat exchanger design is established,which says that for a heat exchanger design with given heat duty and heat transfer area,the total entransy dissipation rate reaches the minimum when the local entransy dissipation rate is uniformly distributed along the heat *** the heat transfer coefficient is unfixed,the total entransy dissipation obtained by the EoED principle is less than that obtained by the principle of equipartition of temperature difference(EoTD).Furthermore,the exchanger effectiveness obtained by the EoED principle is larger than that obtained by the EoTD *** the heat transfer coefficient is fixed,the EoED principle is equivalent to the EoTD *** show that the equipartition of entropy production(EoEP) and EoED principles give rise to difference in entropy generation and entransy dissipation for a heat exchanger optimization *** discrepancies are caused by distinct features of entropy production minimization and entransy dissipation minimization principles,the former is to optimize the design of heat exchanger by making the lost available work minimum,while the latter is not involved with heat-work *** is found that the entropy generation number is not suitable for evaluating heat exchanger performance,since it directly depends on the inlet and outlet temperatures of working *** the contrary,the entransy dissipation number is not directly related to the inlet and outlet temperatures of working ***,the entransy dissipation number is more suitable for serving as a criterion to evaluate heat exchanger performance.

摘要：在柔性设备和静态储能电网应用中,可充电水性锌离子电池展现出巨大的潜力.但其发展受到界面不稳定性引起的副反应及枝晶生长的阻碍.本研究中,我们采用了一种新颖的电解液设计,通过含大量孤电子对的亲锌葫芦[7]超分子来应对这一挑战.这些超分子因其独特的分子结构,能够在电化学循环中有效地吸纳和固定Zn离子,从而有效避免了Zn离子的无序迁移和枝晶的形成.超分子中丰富的孤对电子提供的Lewis碱性位点(如叔胺和羰基氧)作为Zn离子的供电子成核位点,促进了紧密成核.这些超分子与Zn离子之间的强烈相互作用,不仅提高了系统的稳定性,还显著抑制了不良副反应.因此,我们组装的对称电池和Zn//V_(2)O_(5)全电池均展示了长效的循环稳定性和卓越的库仑效率.

摘要：岩体强度与裂隙参数是反映工程岩体质量的基本参数,其准确获取是进行地下工程围岩分级与支护合理设计优化的前提。传统的岩体强度测试方法需要对现场围岩取芯并运至实验室测试,测试结果难以反映工程现场环境下的岩体力学性质,而对于岩体强度与裂隙参数的原位测试方法研究较少。本文基于能量守恒定律,建立了岩石切削能密度与随钻参数的关系式,构建了岩体等效强度随钻反演模型(ES-DP模型),系统开展了岩体数字钻进试验。结果表明,相对于传统测试方法,岩体等效强度随钻测试结果平均差异率为2.4%,验证了ES-DP模型对岩体等效强度测试的有效性。在此基础上,建立了岩体裂隙参数随钻识别模型,与实际测量结果相比,该模型测得的岩体裂隙位置与宽度平均精度分别为1.8和1.6 mm,测试精度较高。基于上述研究,本文提出了一种岩体强度-裂隙随钻识别方法,为实现地下工程围岩强度参数与结构特征的原位实时测试提供了新方法。
