Defending globalisation isleft to a cottage industry of think-tanks, academics and businesslobbies (although some of the most thoughtful studies are quietlyfinanced by pro-market governments, from Finland to the Netherlands, orby the European Union).

为全球化辩护的任务就落到一小部分的智囊人士、学者和商业游说者们的身上了（虽然其中一部分最具思想深度的研究暗中得到了支持市场经济的政府的支助，比如芬兰，荷兰，或者欧盟）。

It utilized factor analysis and regression analysis ofthe multi-statistics to make the quantitative analysis on a great deal of core proxies in the North Indian Ocean and Indonesian Archipelago areas, and acquiredthe exact conversion relations of paleoceanic environment parameters (sea surface temperatureand salinity) and proxies. Then it made the change curve which can show the changes of paleo-ceanic environment parameters (sea surface temperature and salinity) which followed the changesof depth and provided the contrast between paleoceanic environment parameters of different coreson the landscape orientation. This paper supplied a more scientific and exact method for resumingthe paleoceanic environment on paleoceanography research.
