  • Alvarodoa

  • Picramnia




美洲苦木科又名夷苦木科，为美洲苦木目下唯一的科，共有2属约46种，生长在中美洲和南美洲的安第斯山区。


本科植物为乔木或灌木，单叶互生，无托叶；花小，花瓣3-5数；果实为浆果或蒴果。


1981年的克朗奎斯特分类法将其列在苦木科中，属于无患子目，1998年根据基因亲缘关系分类的APG 分类法认为应该单独分出一个科，但无法列在任何一个目中，直接放到蔷薇分支之下。2009年发表的APG III 分类法将本科置于美洲苦木目下。[1]

Volkswagen Group MQB platform

Image
The Volkswagen Group MQB platform is the company's strategy for shared modular design construction of its transverse, front-engine, front-wheel-drive layout (optional front-engine, four-wheel-drive layout) automobiles. Volkswagen spent roughly $60bn [1] developing this new platform and the cars employing it. The platform underpins a wide range of cars from the supermini class to the mid size SUV class. MQB allows Volkswagen to assemble any of its cars based on this platform across all of its MQB ready factories. This allows the Volkswagen group flexibility to shift production as needed between its different factories. Beginning in 2012, Volkswagen Group marketed the strategy under the code name MQB , which stands for Modularer Querbaukasten , translating from German to "Modular Transversal Toolkit" or "Modular Transverse Matrix". [2] [3] MQB is one strategy within VW's overall MB (Modularer Baukasten or modular matrix) program which also includes th...
