1.They can be parted into these classes as follow according to the principle to realize it: 1. Double Stack(RFC 2893 obsolete RFC 1933):The node adopting the technique runs both IPv4 and IPv6 protocol stacks.
按工作原理可划分为：双协议栈（RFC 2893 obsolete RFC1933）：采用该技术的节点上同时运行IPv4和IPv6两套协议栈。
2.12 Monitor obsolete material and continually reduce dollar levels of obsolete inventory.
监控作废的原材料并持续减少作废的库存。
4.Methods From March 1999to June 2003,we treated 14cases of frac-ture-dislocation of proximal interphalangeal joint with elastic dynam ic external fixator. They were 9men a nd 5women,6fresh ones and 8obsolete ones.
方法1999年3月～2003年7月,我们应用弹力型可活动外固定器治疗近侧指间关节骨折脱位14例,新鲜骨折脱位6例,陈旧性骨折脱位8例。
5.an obsolete kind of container used for distillation; two retorts connected by a tube.

6.Researchers are convinced that mass－produced microsatellites, working in groups, will eventually make today’s bulky and more costly devices obsolete.
研究人员相信，批量制造、成组运行的微型卫星将最终淘汰如今庞大而昂贵的卫星。
7.With growth of EAF steelmaking,and limited aVailability and high price of low residual scrap,the electric furnace melt shop operators must use the maximum amount of lowest cost and poor-quality scrap,while staying within the given steel tolerance for residual deleterious elements. Therefore the process of obsolete scrap mixed and diluted with direct reduced iron（DRI） to produce high-quality steel has been developed and the world production of DRI has steadily increased．
随着电炉钢生产的增长及优质废钢供应短缺和价格增长，电炉钢生产者必须使用大量劣质废钢，同时要使钢中残余有害元素符合要求，从而发展了用直接还原铁混合、稀释循环旧废钢生产优质钢材的工艺，并促使世界直接还原铁生产迅速增长。
8.Rural electrification following the Great Depression made farm windmills obsolete.
