奉御董造与禁廷制样:两宋地方官窑执行的御用瓷设计制度

宋朝兴起的地方官窑为宫廷烧造御用瓷是官手工业发展的亮点之一,并逐步形成了两宋地方官窑执行的御用瓷设计制度,设计制度形成绝非偶然,它是宋朝强化皇权意志、器用制度与地方精湛制瓷工艺共同作用的结果。地方官窑主要执行有奉御董造制度、禁廷制样制度。体现的御用瓷设计制度特征十分明显:前期是指专门接受宫廷敕命,由专官管理,奉御烧造宫廷各种用瓷,有命则供,否则止;后期是指宫廷对御用瓷有专门的设计图式,特由礼部礼制局彩画制样后,向地方官窑降发图样烧造御用瓷。尤其是地方官窑执行的禁廷制样须索制度为明代御器厂和清代御窑厂所继承。     

Experimental campaign and assessment of a complete 240-kW Proton Exchange Membrane Fuel Cell power system for maritime applications

This work shows the results of the experimental assessment of the HI-SEA joint laboratory between Fincantieri, the main Italian shipbuilder, and the University of Genova. The HI-SEA system is a 240 kW real-scale test rig complete of auxiliaries, made up of 8 Proton Exchange Membrane Fuel Cell stacks installed on two parallel branches, which can operate independently or in parallel by means of two dedicated DC/DC converters. The experimental assessment is performed by considering: (i) Stationary performance; (ii) dynamic performance; (iii) a maritime operative profile defined together with Fincantieri. The experimental results obtained in this work demonstrated that the system can successfully respond to static, dynamic, and typical maritime operative load profiles. It was also assessed the ability of the system to work simultaneously with two parallel branches, by means of two DC/DC converters, which represents a clear advantage in terms of load sharing and redundance onboard for security issues. Furthermore, the present study gives important advice and criteria for the design, construction, and control of similar Fuel Cell complete systems for maritime applications, which is particularly relevant considering that experimental studies on complete Fuel Cell systems is still limited.

Predictions of frame compliance and apex morphology in sharp nanoindentations

If all components in a nanoindentation system are well calibrated and a reference material has unique hardness, H and reduced modulus, E_r independent of the indentation depths, the load, L and the penetration depth, h in the indentation loading curve of the reference material can be correlated by L=Kh². Here the constant K is expressed by H, E_r and indenter geometry constants. By using H and E_r of a fused silica and the Berkovich geometry, an analytical expression for the indentation loading curve could be derived. To compare with this analytical loading curve, experimental indentation data were measured with two commercial nanoindenters. The experimental loading curves shifted leftward or rightward from the analytical loading curve and this depth deviation was attributed to improper calibration of the nanoindenters. Quantitative calibrations of frame compliance and indenter bluntness were tried for the raw nanoindentation data and this resulted in consistent nanoindentation data regardless of the used nanoindenters.
