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：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。

简介：摘要高质量发展已成为当前烟草行业的主题，消费者对卷烟产品的外观品质有更高的要求，为了避免在“手动”模式下S型提升机不受控，造成缺陷条烟直接流入下道工序的质量隐患，重新编写了S型提升机PLC程序。介绍了条盒透明纸外观检测装置的电控原理。通过重新编写PLC程序对S型提升机系统进行优化，有效地避免了不合格品直接进入下道工序，提高了产品的质量。
