During construction , special building methods were used to limit environmental damage , such as the piles being bored into the seabed rather than pile driven , to avoid mud sediment settling on the corals and killing them . most of the superstructure was prefabricated off - site , brought in by barge and then placed in position by crane to minimise the pollution , rubbish and noise 例如装设支撑中心的桩柱时采用钻挖形式,取代普通的打桩方式,务求减少翻起海床的沙泥,避免珊瑚窒息及死亡大部份上层建筑组件是在建筑地点以外的地方预先制作,并由驳船运到海下,再以吊车装嵌,从而把施工带来的污染垃圾及噪音减至最少。
This paper studies the two problems above . on one hand some necessary improvements are made in existing topology building methods for its higher efficiency and adaptability . on the other hand , a set of methods of updating topology partially are proposed which can reduce the time of rebuilding topology greatly in editing data 本论文重点研究了拓扑关系的建立及其更新问题,一方面对传统的拓扑建立进行了必要的改进,使其具有高效性和通用性;另一方面,提出了一套数据编辑时进行拓扑关系局部更新的方法以减少拓扑重构的时间。
Aligned sequences were imported into mega2 and paup * 4 . 0 for phylogenetic analysis using mp , ml , me and nj method . in each tree - building method , several distance measures or algorithms were used , but all these distance measures or algorithms produced essentially the same results as follows : 1 使用四种常用的建树方法: nj法、 me法、 mp法以及ml法,对斑翅蝗科部分昆虫的系统进化关系进行研究,几种方法所产生的分子树的拓扑结构大致相同,仅在个别种的归属上存在差异。
