二十年后重返餐桌的鲸肉

位于日本本州岛西南岸的和歌山,是日本西部的捕鲸业的中心城市。目前,那里大约有85%的小学和中学已经开始了食用鲸肉的午餐。并且这一政府举动在学生们中间受到了非常广泛的欢迎。据推广这一行动的和歌山教育部门的官员介绍,鲸肉被加工成肉饼或肉球,或者经过甜酸酱腌制提供给孩子们食用,非常适合他们的口味,学生们普遍反映这些鲸肉加工品吃起来很可口。同时,他还表示让日本的孩子们食用鲸肉的目的不仅是希望他们了解日本的捕鲸传统,同时,还可以让他们学习和认识日本

风生水起看铁西--采自振兴东北老工业基地前沿的报告

沈阳铁西区曾经是新中国最大的装备制造业的聚集区,在这里诞生了中国许许多多的工业奇迹,曾当仁不让地成为中国现代工业崛起的排头兵。有人说,振兴东北看辽宁,辽宁看沈阳,沈阳看铁西。转瞬之间,党中央作出振兴东北老工业基地的战略决策已经整整一年。风生水起海生潮。新世纪,铁西又处在中国现代化的潮头浪尖上。让我们把关注的目光与热切的期许,一齐投向铁西,投向这块拥有100万人口的126平方公里的土地,聚焦这一方曾经创造了新中国工业史上无数个第一的“东方鲁尔”。     

重庆中坝遗址地层Na-Ca元素含量揭示的制盐业兴衰史

Based on dynastic period division and AMS ^14 C dating performed on the sedimentary layers at Zhongba and Yuxi sites,and also the analysis of Na,Ca and Mg of 201 sedimentary samples from Zhongba site and that of Ca and Na in 47 sedimentary samples from Yuxi by using an inductively coupled plasma-mass spectrometry（ICP）,we found that there were 35 time periods when the contents of Ca and Na were reversely correlated,i.e.whenever the content of Ca was the highest,the content of Na was the lowest,and vice versa. Among them,there were 21 time periods when the content of Ca was the highest,and Na was the lowest,indicating that there were about 21 prosperous periods of ancient salt production at Zhongba site since 3000BC.Other 14 time periods with the peak values of Na while the low values of Ca indicate 14 declined periods of salt production at Zhongba site since 3000BC.The conclusion obtained from the reverse relationship between Ca and Na contents in this paper is consistent with that＂the salt production at Zhongba site started in the new stone age,developed in the Xia and Shang dynasties,reached at the heyday in periods from the Western Zhou to the Han Dynasties,maintained stable to develop in the Tang and the Song dynasties,and gradually declined after the Song Dynasty because the sea salt were conveyed into Sichuan region,however,still had production in the 1970s-1980s＂,educed from archeological exploration.All the above mentioned results indicate that there is a reverse relationship obviously between the contents of Na and Ca in sediments at Zhongba site for ancient salt production,which can be used to reveal the process of rise and decline of ancient salt industry at Zhongba site.
