The introduction first briefly reviews Western Europe\'s universal order of "recht" in middle ages: As independent political units, the city, the manor, the church parish, the ligeance and so on were set in a rank order, the relations between each rank were established in legal form, empire represented the highest rank, and simultaneously played an arbitrator\'s role, was the arbitrator of political units subordinated to the emperor. All of these ranks were placed in natural order created by God, thus, the Christianity religious doctrine had provided the final validity for the universal legal orders; then the symbiotic of the political evolution and the legal transformation will be discussed. Western jurisprudence resided in the Church during the middle Ages, after entering into modern era, resorted to the state."State" instead of "empire" became the basic concept of modem law, and new order of "recht" was bound to make legitimate argumentation for the nation; finally, the background and sketches of this article is explained. It will trace and analyze intrinsic evolution of the idea of legal order in the background of concrete politics--especially the geopolitics, inspects how the different nation-states split up from universal Christianly world and obtain their independence, inspecting differences of respective national path, the fit or unfit quality and the success or failure in this process.

导论首先简要回顾西欧中世纪大一统的法权秩序：作为独立政治单元的各城市、庄园、教区、领地等被镶嵌在一个等级秩序中，各个等级之间以法律的形式来确立相互之间的关系，帝国代表最高等级，同时扮演仲裁人的角色，是臣属其下的各个政治单元之间的仲裁者，而帝国等级又被安置在上帝创造的自然秩序中，因而，是基督教教义为大一统的法权秩序提供了最终的合法性；接着指出西欧政治演变与法权变革的共生性：西方法学在中世纪寄身于教会之中，进入近代以后则投靠了国家，"国家"代替"帝国"，成为近代法学构造的基本概念，新的法权秩序必然围绕民族国家展开；最后说明本文的论述方式和基本思路：本文将在具体的政治——特别是地缘政治——的背景中，追踪和解析法权观念的内在演变，由此进一步****不同民族国家内、异质的法权秩序如何从过去大一统的世界中分化剥离并获得独立，并试图检讨这一过程中不同民族道路的差异、优劣和得失。

In this work, GC-MS, ICP-OES, UV-Visible Spectrophotometry were employed to determine the trace concentrations of the above six hazardous substances, and a standard method system for screening primarily, extraction, qualitative and quantitative analyses of the six substances was established and their factors were analyzed. By evaluating the relative standard deviation, recovery, repeatability, limit of detection, linear relation etc., the optimum parameters were given and thus the precision of analysis was equal to or higher than the IEC 62321 standard, meeting the requirement of RoHS.
