| 8. | And by means of classification of subjects , we may find their success and fault in the design so that we can integrate theory with practice to ensure the realization of the inheritance and innovation . chapter five explains that the ideology of sustainability such as resources preserving has been crucial in housing design . by the study of design practice of several typical works in the domestic or the foreign , the author tries to explore an ecological design method in the traditional building which is fit for nature and combine it with modern housing design method , so as to obtain a design theory of sustainable housing and its essential ecological adaptability 第4章是从建筑文化继承与创新的角度出发,以后现代建筑风格流派的发展为研究对象,并结合从具体建筑实例中归纳设计手法的种类,通过对其武汉理工大学硕士学位论文符号语言特征予以阐述,进而理清其脉络与结构、分析其基本特征,试图从后现代建筑对于传统建筑符号语言的沿袭与发展这一全新角度来重新审视现代城市居住建筑的成功与不足,以期力求从理论和实例的结合中找出居住建筑可持续发展的一般规律。 |
| 9. | The author investigated the community of grasshoppers in changbai mountain area during the period of july to september 2001 , complementally collected specimen and systematically collected and measured environmental factors from july to october in the following year , and consulted to specimen collected by fengling zhang and yanlong - yang in 1979 , 1980 and 1981 . by analyzing and classifying the data of five years , the author analyzed the community construction and ecological adaptability of the grasshoppers in the area . the main aspects dealing with the grasshoppers are as follows : ( 1 ) the community construction and faunal geographical elements ; ( 2 ) characteristics of their ecological distribution ; ( 3 ) vertical distribution of grasshoppers in the northern slop ; ( 4 ) the relationship between environmental factors and differences in shape of grasshoppers in different vertical belt of northern slop , etc . in terms of faunal geographical elements of grasshopper communities , 48 species of grasshopper were recorded , belonging to 31 genera , 7 families 本文作者于2001年7 9月间系统地调查了长白山地区的蝗虫,并于2002年的7月到10月间对标本进行了补充采集,并对环境因子数据进行了系统的测量和收集,同时参考张凤岭、杨彦龙先生1979 、 1980和1981三年采集的标本,通过对标本的鉴定和整理,采用五年的野外工作数据,对长白山地区蝗虫群落结构及生态适应特性进行了研究,主要研究内容包括:蝗虫的群落结构及区系地理成分;蝗虫生态分布特点;保护区北坡蝗虫垂直分布及不同垂直带内蝗虫的形态差异和环境因子之间的关系等方面内容。 |
| 10. | In the present study , a compartment cultivation system and histochemical staining were used to investigate the influence of soil available p level , plant p status and soil organic p on the growth and metabolic activity of am fungi . differences in metabolic activity among am fungal isolates and the relationship between metabolic activity and mycorrhizal effectiveness were al so investigated . in addition , am fungi from a wide range of environmental conditions ( originally isolated from north , central and south china ) were used to study the ecological adaptability of am fungi and the influence of edaphic conditions on am fungal growth and metabolic activity 本研究采用分室根箱、组织化学等手段研究了土壤施磷水平、植物磷营养状况、土壤有机磷对am真菌生长和代谢活性的影响;不同am真菌的代谢活性及其与菌根效应之间的关系,并对我国华北、华中和华南地区筛选出的高效菌株进行了生态适应性的比较,以期在理论上阐述宿主植物生长状况及土壤条件对菌根真菌生长和代谢活性的调控机制,筛选出具有广泛生态适应性的am菌株。 |
