Based on the field investigations and laboratory examinations, a study of the population of the epiphytic dolichomitriopsis diversformis ( mitt. ) nog. in fanjing mountain reveals that its habitats are different among different host trees, but that there lies the common habitat characteristics of not more than 2m height from the bottoms of host trees trunks, less light, high relative humidity, slow wind speed, slow evaporation speed and long time of remaining humid in middle - lower tree bark ; that it is one dioecious moss species, the morphology is remarkably different between its perichaetium and perigonium, the number of its perichaetia is much more than that of its perigonia, its perigonium is difficult to find out, its sporophyte is upright, its seta is long and thin, its capsule is regular long oval and its calyptra is cucullate
摘要通過野外調查和室內觀測對貴州省梵凈山樹附生尖葉擬船葉蘚種群的研究表明，其生境因其所附生的樹種不同而有所不同，但具有共同特點：附生在樹干下部距地面2m高的范圍之內，光照弱、濕度大、風速小、蒸發量小、中下部樹皮保持濕潤的持續時間長；其為雌雄異株蘚種，雌、雄器苞形態差異明顯，雌器苞數量多，雄器苞數量少並且難于發現，孢子體直立，蒴柄細長，孢蒴規則長卵形，蒴帽兜形。 -
Aiming at this problem, the main research issues and achievements in this paper are as follows : bi - directional data transformation between rdb and xml with semantic constraints preserved for most of existing researches on static data transformation between xml and rdb, dtd is taken as the schema description language for xml, and the semantic constraints are often lost during the transformation process. to overcome these disadvantages, the author adopts xml - schema, a standard schema description language proposed by w3c to replace dtd, as the description method owing to its more powerful functions than dtd, and of course with the syntax much more complicated. after analyzing the constraints characteristics in both xml - schema and relational schema, a semantic constraints - preserved algorithm is proposed which can realize the bi - directional schema mapping between rdb and xml through a formalized description of xml based on regular tree and a general expression for relational schema based on direct graph approach
保留語義約束的xml與rdb雙向靜態數據轉換技術現有研究大多採用dtd （ documenttypedefinition ，文檔類型定義）作為xml的模式描述語言，並且在模式映射過程中丟失語義約束信息，本文分析了xml - schema （ xml - schema採用與dtd完全不同的語法，數據描述能力更強同時也更為復雜，已被w3c確定為替代dtd作為xml模式描述語言的標準）及關系模式的語義約束特徵，通過基於正則樹的xml形式化描述方法以及基於有向圖的一般關系模式表示方法的研究，建立保留語義約束的xml - schema與關系模式的雙向模式映射演算法，實現了xml與rdb的雙向數據轉換，較好地解決了xml與rdb在靜態數據轉換層面的數據集成問題，可有效滿足企業大量rdb數據面向xml的發布以及與日俱增的xml數據存入rdb的應用需求。 -

The hibernation of this lemur is strongly dependent on the thermal behaviour of its tree hole : if the hole is poorly insulated, the lemur ' s body temperature fluctuates widely, passively following the ambient temperature ; if well insulated, the body temperature stays fairly constant and the animal undergoes regular spells of arousal

In the thesis, compatible data storage fashion and data structure for a large - scale 3d scene is discussed firstly. then the process technique for dem, spatial object geometry data, texture image data and scene metadata are discussed in turn. finally, a new nested index, scene pyramid + sub scene regular dividing quad - tree is brought forward, which consumes less memory and reduces the complexity of spatial data query
