Integrating the hydrogen production technologies from renewable energy with the advanced distributed hydrogen power systems has being become an important development trend of energy science and technology in the twenty-first century, since it may satisfactorily solve such problems met in the utilization of renewable energy as low density, instability, discontinuity and changing with time, season and climate. In this paper, the status and prospect of studies on hydrogen production theories and technologies from renewable energy especially the photocatalytic water splitting and the thermochemical catalytic gasification of biomass in supercritical water are commented on, and some new suggestions to build up novel hydrogen energy power system based on renewable energy are put forward.

浅谈山西开国纪念铜币

中国钱币 1993年第3期 58-,30页

浅谈山西开国纪念铜币张培林民国伊始，各省又纷纷铸币，孙中山先生深感铸币事关重大，遂于民国元年３月９日“临时大总统令”中指出，“查币制改良，新民耳目，自属要图……其余通用新币中间应绘五谷模型，取丰岁足民之义，垂劝农务本... 详细信息

浅谈山西开国纪念铜币张培林民国伊始，各省又纷纷铸币，孙中山先生深感铸币事关重大，遂于民国元年３月９日“临时大总统令”中指出，“查币制改良，新民耳目，自属要图……其余通用新币中间应绘五谷模型，取丰岁足民之义，垂劝农务本之规。”所以民国初期，各省所铸开国纪念铜币，其基本图案多为嘉禾图和双族图，最初的“双旗”，为“十八星军旗”和五色国旗，其后改为国民党党旗和国民党政府旗。据史科记载，民初铸造开国纪念铜币的省份主要有：湖北（武昌造币厂）、江苏（南京造币厂）、安徽（安庆造币厂）、湖南（长沙造币厂）、河南（开封造币厂）及山西（太原造币厂）等①。但何为山西所铸开国纪念铜币，却不大清楚。笔者在铜元收集中，偶遇一品（图１），面值为“壹枚”，直径２．７８厘米、厚０．１５厘米、重６．５克，铜质略黄。虽品相不精，但图文均能清晰，正面中央铸竖读“壹枚”二字，左右嘉禾环绕；背面中央为双旗图，分别为十八星军旗和五色国旗，上缘铸“中华民国”，下缘铸“开国纪念币”，左右两侧为“卷草花”。笔者认为，此币应为山西所铸之开国纪念铜币，是山西机铸铜币的初铸品，铸造时间应在民国七年（１９１８）以后。理由有三：民初各地所铸开国纪念铜币。

Concentrating solar thermal power system can provide low carbon,renewable energy resources in countries or regions with strong solar irradiation.For this kind of power plant which is likely to be located in the arid area,natural draft dry cooling tower is a promising choice.To develop the experimental studies on small cooling tower,a 20 m high natural draft dry cooling tower with fully instrumented measurement system was established by the Queensland Geothermal Energy Centre of Excellence.The performance of this cooling tower was measured with the constant heat input of 600 kW and 840 kW and with ambient temperature ranging from 20 ℃ to 32 ℃.The cooling tower numerical model was refined and validated with the experimental data.The model of 1 MW concentrating solar thermal supercritical CO2 power cycle was developed and integrated with the cooling tower model.The influences of changing ambient temperature and the performance of the cooling tower on efficiency of the power system were simulated.The differences of the mechanism of the ambient temperature effect on Rankine cycle and supercritical CO2 Brayton cycle were analysed and discussed.
