Weather fresh onion or onionskin dry powder, the yield of polysaccharides obtained by microwave-assisted freeze thawing was the most, and the content of polysaccharicle obtained by utrasonic wave was the most. The yield of polysacchalides obtained by microwave-assisted freeze thaucing in onionskin was 3.58%(the content of polysaccharides was 63.9%); and its yield in fleshy parts was 3.15%(the content of polysaccharides was 62.0%).

不管是新鲜洋葱肉质部分还是洋葱皮干粉，微波辅助冻融法提取的多糖的得率最高，超声波法提取的多糖的含量最高，其中微波辅助冻融法提取洋葱皮中多糖得率为3.58%(含量为63.9%)；肉质部分多糖得率为3.15%（含量为62.0%）。

This paper use H.264/AVC video transmission, which defines a set of three Profiles. Applications of the Baseline Profile include video telephony, video conferencing; applications of the Main Profile include television broadcasting and video storage; and the Extended Profile may be particularly useful for streaming media applications. H.264 proposes the idea of Network Abstraction Layer. The output of the encoding process of VCL data will be packeted into NAL units. The NAL will give the NAL units corresponding header information according the contents of the units.

而本论文在采用的多媒体压缩技术－H.264/AVC，其定义了三种不同的Profile：Baseline Profile著重在视讯电话，视讯会议等偏重即时传输等服务类别，Main Profile重点则是电视的播放以及影像储存的应用，而Extension Profile则是在串流媒体的播放上提供了较多的技术支援。H.264/AVC并且率先提出了网路提取层的概念，影像在视讯编码层完成编码之后，移交到网路提取层中，而网路提取层会依视讯编码层产生的编码内容将其封装近NAL units，并给予应有的标头资讯。
