语言作为思维的载体,受思维模式的支配,二者相互影响,互为表征。本文探讨了英汉思维模式的差异对其语篇结构的影响。通过比较,我们可以了解掌握因不同思维模式所形成的特有的篇章结构,以激发学习者对不同母语的英语的敏感性。 相似文献

A Gram-negative, facultative autotrophic bacterium strain PJH was isolated from the acidic mine drainages sampled in Dexing Mine, Jiangxi Province, China. The isolate grew in a pH range of 1.0 6.0, with pH and temperature optima of 3.5 and 40 ℃, respectively. Spectroscopic experiments show that strain PJH can synthesize polyhydroxybutyrate (PHB). A phylogenetic analysis based on 16S rRNA sequences shows that the isolate belongs to the genus Acidiphilium. Strain PJH has the capability of leaching chalcopyrite. Bioleaching experiments show that it can improve the leaching rate of chalcopyrite by 10.3% when mixed with L. ferriphilium YTW315 after 35 d. Strain PJH has the potential in application to bioleach chalcopyrite with other mesophilic leaching microbes. 相似文献

为提高米制品中转基因成分实时荧光PCR检测的灵敏度与检出率,以及优化样品中转基因成分的检出效果,以添加不同转基因含量的米制品(米粉干)为模拟转基因样品,对影响检测效果的因素包括样品颗粒细度、DNA提取过程中样品在CTAB裂解缓冲液中温育时间等因素进行分析。结果显示,当样品颗粒细度>100目、CTAB温育时间达到8h条件下,样品DNA提取及荧光PCR检测结果最好;在最优化的条件组合下,样品转基因成分的检出限可达到0.001%转基因含量,是通常认为的荧光PCR检出限0.01%的10倍。 相似文献
