我最喜欢吃葱了.煮面要放葱,凉拌菜必放葱,红烧肉起锅要放葱……这么说吧,烧、烤、煎、炖,无“葱”不快.没有菜,豆瓣酱拌上葱,我就能吃下两碗饭.
In this paper the mixing of a sample in the curved microchannel with heterogeneous surface potentials is analysed numerically by using the control-volume-based
妈妈是一个名副其实的“花痴”。 每个周末，妈妈都会抽出时间去花市逛逛。整条街熙熙攘攘，各种各样的花草琳琅满目。妈妈摸摸这盆，闻闻那盆，瞬间踮起脚，又猛然蹲下身子，不知疲倦，穿梭在各种鲜花、绿草中，陶醉在美不胜收的绿色海洋中。 突然，我发現妈妈盯着一盆兰花愣住了神儿。这盆兰花的叶子如长剑，看着高垂柔弱，摸上去却坚韧无比。“这是什么品种的兰花？怎么养的？”妈妈认真地问起老板。“这是寒兰，喜欢阳光，
马铃薯作为世界上第四大粮食作物,同时也是中国的第四大粮食作物,在人民生活中占着越来越重要的地位。马铃薯全基因组测序的完成,帮助人们加深对马铃薯遗传规律的了解,加强对其丰富的遗传资源的开发,同时也加快分子育种的运用。双单倍体马铃薯DM(DM13-516-R44)为测序材料之一,本研究以它为材料,通过农杆菌介导将构建好的增强子捕获T-DNA载体导入马铃薯的外植体中,获得转基因植株,得到转基因植株后,利
