In order to solve these problems about juridical person system of private school in China, the paper offers several countermeasures. According to setting up school corporation in legal qualification in Japanese private school, we should properly revise our present educational law and add special items and regulations about setting up school corporation; we also should revise some statutes and items restricting juridical person's capacity for fund-raising and financing, adjust some policies and rules which are bad to funds raising. At the same time we need introduce the experiences of school corporate fathering system of private school in Taiwan and especially in Japan. To set up staff selecting mechanism about corporate organ in private school, to reform management patterns and perfect organizing mechanism of corporate organ in non-profit private school, to carve up the rights borderline between the council and principal, we could establish the reasonable and normative corporate management system of private school in the future.

为解决我国民办学校法人制度的现存问题，论文提出了相应的具体对策：借鉴日本在教育领域对私立学校的法律主体资格专设&学校法人&的经验和做法，适当修改我国现行的教育法律，增加设立&学校法人&的专门条款及其相关内容规定；修改制约民办学校法人主体筹资融资能力的一些法律法规条款，调整不利于民办学校筹措资金的诸多政策规章限制；在借鉴台湾地区、尤其是日本私立学校有关学校法人治理制度的经验基础之上，增加有关民办学校法人机关组成人员的来源和遴选机制，改革和完善目前我国民办学校尤其是从事非营利活动的民办学校的法人机关运作机制，合理划分校董事会与校长的权限，从而确立起完善和规范的民办学校的法人治理制度。

In macroscopic, the sudden and rapid rise of rural juvenile delinquency rate in social transition has profound social root and intrinsic mechanism. The social polarization caused by city - countryside - dual society structure is the social root of rural juvenile delinquency, and the existence of each kind of social exclusion is the intrinsic mechanism; In medium reasons, the rural juvenile delinquency is the result of family, school, companion community, mass media as well as other bad affection factors; In microscopic, the rural juvenile delinquency is inseparably related to rural juveniles low degree of schooling, the lack of legal consciousness, the desalination of morality and the lost of value orientation and so on.

从宏观上，社会转型期农村未成年人犯罪率的急剧上升、迅猛增长有着深刻的社会根源和内在机理，由社会发展失衡和城乡二元社会结构所导致的社会极化是农村未成年人犯罪的社会根源，各种社会排斥的存在是农村未成年人犯罪的内在机理；从中观上，农村未成年人犯罪是家庭、学校、同伴群体和大众传媒等社会化机构的不良影响所致；从微观上，农村未成年人自身文化程度的低下、法律意识的淡薄、道德观念的淡化和价值取向的迷失等与其犯罪也有着密不可分的联系。

Combining the mechanism of oxygen diffusion with the block model in YBCO, the mechanism of the phase transitions can he explained as follows: the phase transition at 400℃ comes directly from O(1) in the rock salt block, and corresponds to the beginning of O-T; the phase transition at 850℃ corresponds to the end of O-T, when O(2) and O(3) of Cu(2)-O plain are rearranged and a few oxygen enter O(1) site of Cu(1)-O plain through O(4) bridge atom, and at last escape from the crystal cell. Thus the phase transition at 850℃ is related with the pervoskite block.

结合YBCO中氧扩散机制和块模型，相变机理解释如下：400℃的相变直接来自于岩盐块，对应于正交－四方转变的起点；850℃相变对应于正交－四方转变的终点，此时Cu(2)-O面中的O(2)和O(3)重排，一些O通过O(4)桥原子进入O(1)位，最后逸出晶胞，因而850℃相变与钙钛矿关系密切。
