查询词典 quantitative analysis

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.

As to the high polarity, high boiling point resultant—trimesic acid, the analysis methods of infrared spetrum, gas chromatography-mass spectroscopy, vapour-phase chromatography, acid number titration and so on are seperately used to characterize its property. Infrared spetrum and gas chromatography-mass spectroscopy are used to have a qualitative analysis on the resultant and are compared with the stand diagram. Sulfuric acid-methanol esterification and rapid esterification are used to prepare the trimesic acid trimethyl-ester and have a FID quantitative analysis. So that we make sure the purity of trimesic acid in the resultant and also we have an acid alkali titration on the resultant to get its acid number, in order to verify the purity of trimesic acid in the resultant.

Therefore international business communication should be given the particular attention for its specialty and complicities to indicate the stylistic features of this register. Since the corpus-based approach and the computerized analyze in stylistic analysis are more accurate and more scientific, the compared data and the observation results are shown on the basis of comparison between IBC and other registers, which include LOBA, BROWN, CET4, NEC, MEE and MTE. This thesis aims at making a quantitative computerized stylistic analysis on the following aspects: graphetics, layout, punctuation, vocabulary, words of top frequency, word length, diachronic deviation, abbreviation, sentence length, passive voice, cohesive devices, sentence group and discourse analysis.

本文在国际商务英语书信文体特点分析研究的过程中，基于语料库计算机化的科学准确的分析方法，在对商务英语函电文体与普通英语文体，四级英语(CET4)，海事公约文体，航海英语文体和轮机英语比较的基础上，从书写，格式，标点符号，词汇，高频词，词长，词汇变异，缩略语，句长，被动语态，连接词，句群以及篇章模式等方面归纳总结了商务英语书信的文体特点。

Based on the survey of community plots, a quantitative analysis of the communities at Luya Mountain is performed with TWINSPAN Two Way Indicator Species Analysis and DCA Detrended Correspondence Analysis methods. 82 quadrates collected from Luya Mountains were classified into 28 types by TWINSPAN, which belong to seven vegetation types. The result of DCA indicated that those 28 types were reliable. Diagonal line of the two-dimensional ordination diagram of DCA reflects the gradient changes of elevation, temperature and humidity. It is considered that the major factors that restrict the community distribution of the mountains are elevation、temperature and humidity.
