研究

In general, this issue belongs to the category of environmental history. While when it comes to some specific issues, trace element in soil is the cut-in point to study the changes of Chinese ancient society. At the present time, such research method hasn\'t been applied in history studies domestic and abroad so far. Therefore, the studies of the paper are only exploratory and immature researches.Three issues are concerned here:lTrace element in soil under geographical environment and the Hun and the Hsienpei\'s levirate.

本文主要探讨地理环境下的土壤微量元素与中国古代社会变迁的关系问题；在总体上，这一专题是属于环境史的范畴；但在具体问题上，则是以地理环境下的土壤微量元素问题做为切入点，来研究中国古代社会变迁问题的；就目前的情况看，这种研究方法在国内外历史学的研究中尚无先例；所以，本文的相关研究只能是带有一些探索性的、不成熟的研究。

In china, the research on ground stone tools focused on pre-historical stone typology, and then used the conclusion to study the communication and the influence between different cultural communities. The research on technology and function of the ground stone tools still is in the preliminary stages. Some issues, such as lithic resource, theories and the methods have not been set up.

我国关于磨制石器的研究，主要集中于史前石器类型学上的考察，进而研究文化群之间的相互影响与交流；关于制作工艺、工具用途等研究尚处于起步阶段，产地研究等还是空白，理论和方法尚未建立；学者多注重个案并非石器组合的研究。

And we established a new material which included some sortable indexes to each base logogriph, such as difficulty, accuracy and reaction time. Each pair of riddles included one base logogriph and a target logogriph. A new experimental paradigm was also adopted: a two-stage model for learning-testing, so as to research the time course of successful insight problem solving. Firstly, subjects learned a logogriph (a base logogriph with the answer offered)—learning stage, and then they were asked to solve a homotypical logogriph (a target logogriph, and the base logogriph learned beforehand would provide heuristic information for solving the target logogriph)—testing stage.

在原型激活理论的指导下，本研究通过实验1与实验2初步建立了用于顿悟认知与脑机制研究的字谜材料库，弥补了以往顿悟脑机制研究材料方面的欠缺，主要表现为：首先在材料类型上保证了同质性，都是选用的中国传统文化中的字谜；其次，有足够多的数量，能够满足脑成像研究的多次重复测量和叠加的要求；再次，材料是一一配对的，即每对字谜都由源字谜和靶字谜共同组成，便于研究原型启发效应；最后，提供了多数字谜材料的相关信息，每一个字谜都有正确率、反应时、启发量、巧妙性、难度等分类指标。
