基于类型学方法的现代园林景观文脉传承研究

景观文脉的传承始终是当代风景园林师关注的一大课题.现阶段,我国的园林建设面临盲目西化和符号化倾向,造成传统景观文脉严重缺失.该文在梳理建筑类型学核心理论的基础上,通过适用性分析,论证类型学方法对于解决文脉传承问题的有效性,进而将类型学方法移植至园林景观领域,结合我国的具体历史和地域文化条件,对类型学设计模式中的类型选择和类型转换进行了详尽的阐释和分析,旨在为现代园林设计中的景观文脉传承研究提供一种全新的思路.

碧桂园长寿桃花商业街规划设计

建筑设计的精致化趋向,使仿古建筑的规划、设计亦需较精准演绎所在地区传统文化、传统建筑特色。同时,其创造性传承部分又需契合现代人审美需求。演绎即由一般至特殊,整体至个体的推理方法,这也是系统工程论的重要观点。通过对巴渝文化、建筑特色、长寿当地文化等环节之逐层“演绎”,较系统总结了一套针对地域文脉传承的规划区规划设计模式。将商业经营与文化传播、商业业态规划与建筑规划有效结合,以赋予规划区持久生命力。

Molecular evidence for maternal inheritance of the chloroplast genome in tea,Camellia sinensis (L.) O. Kuntze

BACKGROUND: Tea is the most consumed beverage worldwide after water. Yet very little is known about the genetics of tea in comparison with other crop species. Here we have taken advantage of the polymorphic nature of microsatellite DNA to investigate the mode of chloroplast inheritance in tea, Camellia sinensis (L.) O. Kuntze. This is important for the correct interpretation of phylogeny and introgression data as well as assessing the suitability of chloroplast transformation as a means for transgene containment in tea. RESULTS: The study was based on six Japanese tea cultivars, namely Aj2, CK23, Hatsumomiji, Nka05, Yamanoibuki and Kanayamidori used to generate four informative families. The parental pairs in the crosses differed at a single chlroroplast locus with respect to an imperfect microsatellite repeat of 16 nucleotide bases. In agreement with earlier cytological studies, all 61 progeny displayed a cpDNA profile that was consistent with the maternal inheritance of chloroplasts in tea. CONCLUSIONS: The data generated here provide the first molecular evidence of the plastid inheritance in tea. However, we suggest that additional families and polymorphic markers be screened for increasing the confidence in the observed maternal inheritance of chloroplasts in this important crop species.

Defeasible inheritance with doubt index and its axiomatic characterization

This article introduces and uses a representation of defeasible inheritance networks where links in the network are viewed as propositions, and where defeasible links are tagged with a quantitative indication of the proportion of exceptions, called the doubt index. This doubt index is used for restricting the length of the chains of inference.The representation also introduces the use of defeater literals that disable the chaining of subsumption links. The use of defeater literals replaces the use of negative defeasible inheritance links, expressing “most A are not B”. The new representation improves the expressivity significantly.Inference in inheritance networks is defined by a combination of axioms that constrain the contents of network extensions, a heuristic restriction that also has that effect, and a nonmonotonic operation of minimizing the set of defeater literals while retaining consistency.We introduce an underlying semantics that defines the meaning of literals in a network, and prove that the axioms are sound with respect to this semantics. We also discuss the conditions for obtaining completeness.Traditional concepts, assumptions and issues in research on nonmonotonic or defeasible inheritance are reviewed in the perspective of this approach.     

建筑—时代的印记

文章指出建筑是历史的石册,人类文化集中的反映,是社会发展的重要侧面和缩影.建筑的发展处在时代的变动中,在不同程度上都反映着这种、那种印记.当前应以思变、创新的意识,对建筑创作中出现的纵向承传、横向渗透、文化关联、方法更替、多向兼容问题作进一步地分析.文章从基本理论出发,结合实际例证对纵向承传、横向渗透、文化关联、方法更替、多向兼容作了分析,说明它们存在的社会、经济、文化、政治基因以及其在建筑创作中的倾向,指出应当采取的正确态度.

铸铁合金的遗传效应及其利用

研究了亚共晶，过共晶铸铁合金液在不同热状态下凝固组织，以及组织对力学性能的影响等，发现，炉料对铸件产生明显的组织遗传效应，随合金液过热温度的升高，铸件吉石墨相的数量减少且变细，碳化物增多，组织趋于均匀，合金的硬度提高，冲击韧性下降；随合金液保温时间延长，组织遗传性衰退，石墨相球化，碳化物变细，设计的热处理新工艺能提高合金的力学性能，根据遗传观点，分析了试验结果及其意义，探讨了热速处理的作用机理。
