  • 简介:春节过了,咱们就正式进入了“猪年”,猪是十二生肖里的最后一位,这年翻过去就又是一个新的轮回。在猪年开始没多久,咱们就在“档案馆”里做了一个稿子,讲的是人类对猪的驯化。虽然猪老是跟不好的词儿连在一起,比如“猪头猪脑”——可是猪头猪脑真的很好吃啊——不过,猪其实真算得上是人类的好朋友了,因为它在很大范围内给人类提供了食用的肉,还有可供加工的皮革,甚至是它们的猪鬃毛,都曾经是重要的军需用品呢。第二次世界大战时,枪炮、军舰、飞机等的清洁和喷漆,一样也离不开猪鬃,中国还是最大的猪鬃出口国。从猪的驯化历史,我们可以看出人类是怎么样将自然资源变为自己可用,而在不同文化背景下的人类,又是如何看待自然。

  • 简介:摘要摩托车车架的设计在实际的研发和生产过程中,需要经过很多环节,并且摩托车的整体车身的覆盖形式和具体的零部件设计以及组装,难度非常大,在装配精度和组装位置上的关系难以得到保障,在这其中,车架的设计中某个环节要进行参数的改变,就将要对其他所有的零部件进行重新的调整和规划,因此这对于整车的生产效率和开发时效都极为不利,极易造成资金、人力和技术的浪费。所以,采用WAVE技术将很好的解决此类问题,WAVE技术将主要的整车研发到实际的组装以及中间部分的模具的使用,都能够很好的进行关联,使得在改进车身尺寸和参数的情况下,无需对其他零部件进行重新设计,会直接对其进行尺寸和参数的更新,这就将极大的提高摩托车整车的开发和组装效率。

  • 简介:通过对20世纪80年代以来具有代表性的华北夏谷区审(鉴)定的20个主栽谷子品种进行SSR标记多态性分析,研究了华北地区育成谷子品种的遗传多样性。49对引物在20个谷子品种中扩增出具有多态性的条带,共检测出142个等位变异,平均每个位点检测出的等位变异数为2.96个。标记位点多态性信息含量(PIC)变幅为0.0904~0.6896,平均为0.4168。20份材料间的遗传距离变幅为0.0173~0.9000,聚类分析将其分成3个类群,其中谷丰1号自成一类,表明谷丰1号的遗传距离较其他品种大。不同年代谷子品种间遗传距离分析结果显示,各年代品种之间的平均遗传距离由大到小依次是1980s>1990s>2000s>2010s,表明随着年代的递进育成品种的遗传差异减小,亲缘关系增近。
