试论南京国民政府对我国盐政主权的收回

南京国民政府成立后，在关税自主、恢复和保留盐务稽核所的同时，通过变更职权和对洋人任用的变更开始了收回我国盐政主权的活动。南京国民政府当时对我国盐政主权的收回活动，现在看来，具有一定的历史意义。     

Environmentally-induced stone decay: the cumulative effects of crystallization–hydration cycles on a Lincolnshire oopelsparite limestone

An investigation has been undertaken at St Andrew’s church, Walpole St Andrew, Norfolk, to establish the underlying causes of the observed stone decay to the upper parts of the six stone piers. The stone decay was first recorded in the early 1930s. The salt-contaminated masonry within the church has been shown to undergo severe salt decay during the summer, with little damage occurring over the winter months. The south aisle piers have been shown to decay 2.5 times faster than the north aisle piers. Although crystallization–hydration cycles have been identified, the rate of decay is at its greatest when the cycling is relatively infrequent. This was not the expected trend. Furthermore, it has been shown that during extended periods where the ambient relative humidity is less than 75%, the rate of decay reaches a maximum. It is the length of this ‘drying’ period that apparently has the greatest influence on the rate of decay and could explain the significant difference in the rate of decay between the south and north aisle piers. The results have serious implications for passive conservation, where it is often recommended to lower the ambient relative humidity to well below the equilibrium relative humidity of the salt contaminant, to avoid crystallization–hydration cycles. Since, at the time of building, the church was situated on the coast, it is possible that the sodium chloride contamination occurred during the building process (1440–1520), particularly since the area was prone to sea-flooding at this time. Alternatively, the salt could have been applied as a treatment during the general restoration of 1897. Whatever the source of the salt, it seems likely that the ambient environment was changed by the insertion of a sealed floor in 1897, which could account for the onset of the salt decay.     

民粹主义与巴金早期的创作

民粹主义源于俄国 ,它与无政府主义有着错综复杂的关系。由于时代的误读 ,巴金在接受无政府主义思想的同时 ,也深受民粹主义的感染。民粹主义在巴金早期的作品中留有鲜明的印记     

论海盐文化在重塑现代化“盐”城形象中的地位

盐城有着两千多年的产盐历史，聪慧勤奋的盐城人创造了灿烂辉煌的海盐文化。底蕴丰厚的海盐文化遣存是中国海盐业发展的历史缩影。璀灿的海盐文化是盐城沟通世界的桥梁。多元的海盐文化符号融入城市建设是重塑名实相符的现代化“盐”城的必然选择。     

巴渝诗鸟瞰

巴渝诗是巴渝大地孕育、生长的学奇葩，堪称源远流长。具发展大体可分三个阶段：唐前为滥觞期，唐、宋为鼎盛期，元、明、清则走向衰落。巴渝诗是外籍作家和本土作家共同创造的结晶，是巴渝学中的瑰宝，无愧为巴渝化璀璨的明珠，自有其鲜明的特色和不朽的成就。     

江永女书的魅力

社会主义建设初期,我国出现了一个以王瑶《中国新学史稿》为代表的现代学史个人写作的小高潮。由于时代话语的原因,这一时期的现代学史作呈现的多是集体话语,个人话语在一定程度被遮蔽了,阶级论、人民性等是这些作所共有的关键性术语。在对作家的审视上,这一批作为“鲁郭茅,巴老曹”模式的确定奠定了基础。

盐胁迫对红麻种子萌发及幼苗生长的影响

研究了不同浓度的钠盐（Na2SO4和Na2CO3）胁迫对红麻种子萌发和幼苗生长的影响.结果表明：不同浓度盐胁迫对红麻种子的发芽指标和活力指数均有一定抑制作用,随浓度的增加抑制作用越强.浓度10~50 mmol/L的Na2SO4胁迫下,红麻种子的发芽势、发芽指数与对照没有显著差异,但活力指数显著低于对照,而当Na2SO4浓度为100 mmol/L时种子的发芽势、发芽指数与对照存在显著差异,Na2SO4浓度为200 mmol/L时种子不能萌发;Na2CO3浓度≥50 mmol/L时,红麻种子不能萌发.相同浓度下,Na2CO3比Na2SO4对红麻种子萌发的抑制作用更明显.     

NaCl胁迫对不同番茄品种幼苗及果实的影响

研究了NaCl胁迫对5个不同番茄品种的幼苗生长、果实可溶性糖含量及产量的影响.结果表明,盐胁迫抑制了番茄幼苗植株的生长,降低了幼苗的单株鲜重,减少了果实产量,但可以提高果实可溶性糖含量.同一盐胁迫条件下,不同番茄品种性状存在显著差异.
