The semi-solid slurry of hypoeutectic Al-Si alloy was manufactured by low superheat pouring and weak electromagnetic stirring. The effects of pouring temperature and stirring power on the semi-solid slurry making process were investigated. The results indicate that the semi-solid slurry to satisfy rheocasting requirement can be made by a combination of low superheat pouring and weak electromagnetic stirring. The pouring temperature (or superheat) and the stirring power significantly affect the morphology and the size of primary α-Al, while there is no obvious effect of the stirring time on primary α-Al. Compared with the samples made by low superheat pouring without stirring, the nucleation rate, particle morphology and grain size of primary α-Al in A356 Al alloy are markedly improved by a process of applying both low superheat pouring and weak electromagnetic stirring. Under the condition of weak electromagnetic stirring applied, the pouring temperature with low superheat can be equivalently to reach the effectiveness obtained from the even lower pouring temperature without stirring.

关键词： semi-solid low superheat pouring weak electromagnetic stirring hypoeutectic Al-Si alloy A356 Al alloy

本文对环太湖地区马家浜文化时期的聚落遗址进行了全面收集,并结合地理学方法对聚落演变的动态过程和空间特征进行了研究。马家浜文化早中期聚落稀疏,以较高海拔的岗地型为主,在中期时出现中心聚落。晚期时遗址数量剧增,有一定数量的平地型和台墩型聚落,呈现出多等级的聚落结构。逐渐改善的自然环境为聚落发展提供了优越条件,在独特的地理空间内,聚落分布表现出既相对统一又多区并立的格局。聚落选址具有高度亲水性,也十分注重对水的防控,其空间分布基本格局为江南地区的聚落模式奠定了基础。

马家浜文化早期居址以干栏式为主,晚期以土木混合结构的地面式建筑为主要形式。房屋具备良好的防水性能,建筑技术尤其是木构件制作颇为先进。聚落中的生活设施包括水井和户外活动场地;生产设施包括制造场、水稻田和养殖坑,反映了马家浜文化合理的生业结构。部分遗址发现了专门的祭祀遗存,表明当时的社会存在浓厚的宗教氛围。马家浜文化依托水源建立聚落,因地制宜规划聚落布局,是与自然环境相适应的生存方式,奠定了环太湖地区水乡聚落的基本形态。

白昂是明代治水名臣,白氏家族在当时和后世颇具名望。白昂家族三位女性的墓志铭,记载了白氏世系传承、官职迁转与家族兴盛的过程,与明代中期的治水、民乱等系列事件有密切联系。白昂旁荫其侄入国子监是家族中的重大事件,碑传文中多次提及,对于研究明代的荫监制度具有参考价值。白氏园林盛甲一方,明代诗作、绘画中屡有描绘,有些出自名家手笔,本文对园林的建造与沿革进行了整理、分析。三方墓志与传世文献彼此呼应,反映出品官家庭中女性社会地位和日常生活的差异,是研究明代女性生存状态的珍贵资料。白氏家族碑传文牵涉政治、文学人物众多,关系错综复杂,本文对志文作者进行了考证。这三方墓志对于补充丰实史籍记载,研究明代历史变迁及江南地区官僚家族的社会生活,具有重要的史料价值。
