The second classification principle of organisms is the lineage classification principle aiming at establishing evolutionary lineage. The classification method following this principle is called lineage classification. The representative of pedigree classification is "branch systematics". It advocates that the branches in evolution should be taken as the criteria for identifying and distinguishing classification units and the basis for determining the pedigree relationship of each classification unit. The so-called co-ancestral proximity (similar to a group of people being a grandfather) is used to measure the genetic relationship between different taxa and determine their position in the pedigree. The classification system finally established is an evolutionary pedigree reflecting the history of phylogeny, which is a deeper description of biological relationship. In other words, the basic principle of pedigree classification is that the classification system conforms to the evolutionary pedigree. Pedigree classification is only applicable to organisms and cannot be used for abiotic classification.Industry 4.0 proposed by Germany has three major themes: first, intelligent factories, focusing on intelligent production systems and processes, and the realization of networked distributed production facilities; The second is intelligent production, which mainly involves the production logistics management of the whole enterprise, human-computer interaction and the application of 3D technology in the industrial production process. The third is intelligent logistics, which integrates logistics resources mainly through the Internet, the Internet of Things and the Internet of Services to give full play to the efficiency of existing logistics resources.3 to play N64 games and PS games, need Wii classic handle, otherwise the key position is not enough1942年，正在抗日战争焦灼之时，日军突袭新四军在北方地区的一处兵工厂，保卫兵工厂的独立团特务连浴血奋战，终因寡不敌众，阵地失守，连长孔圆被俘。孔圆的哥哥孔方是一名大学数学教授，精通数学逻辑分析，曾留学日本，对日军的情况有所了解。在新四军帮助下，孔方和未婚妻——心理学教授向海音混进日军占领区，里应外合，发动反攻，成功救出了弟弟和兵工厂人员并夺回了阵地。本剧取材于黄崖洞兵工厂保卫战以及众多兵工厂事迹，用普通人的事迹展现出一幅各阶层人民联合抗战的生动历史画卷。侍女走到尹旭身前道：禀报大王，子夜夫人生下一位公主。
