In this paper, a series of lunar map projection formulas are deduced including azimuthal projections, cylindrical projections and conical projections. The lunar map projections software is compiled. By caculating lunar map projection distortions, their projection distortion rules are found. Base on the lunar exploration mission, the lunar map projection scheme is given in this paper. The azimuthal conformal projection or the circumcenter perspective azimuthal projection is usually used in small areas, especially in two poles. When the whole map of the moon is needed, the azimuthal conformal projection or the circumcenter perspective azimuthal projection is used within 10° in the poles, and the traverse tangent cylindrical conformal projection or the normal secant conical conformal projection can be used in else areas, furthermore, band-division is necessary to reduce the projection distortion.

本文推导了基于月球参考球的各种投影公式，主要包括方位投影、圆柱投影和圆锥投影；编制了月球地图投影计算软件；对多种月球的投影变形进行了详细的计算，总结分析了各种月球投影的变形规律；结合月球探测的需要，给出了月球投影方案的建议：对于局部的面积较小的投影区域，建议使用等角方位投影或外心透视方位投影；如果绘制月面全图，在两极10°范围内采用等角方位投影或外心透视方位投影，其余区域可以采用等角横切圆柱投影和等角正割圆锥投影，并且要进行分带处理。

This study describes the multi-facet systematic evolution of the said rural community from 1907 to 2007: from the perspective of ethnic culture, it has changed from a single ethnic cultural community of Yoghur(Ethnic Yugur\'s self-name) ethnic group into a multi-ethnic cultural community with Yoghur ethnic group as the dominating majority and embracing the ethnic groups of Han, Tibetan, Tu, Mongolian and Kazak; from the perspective of language, it has changed from a community where Yoghur and Tibetan languages dominated with the local Chinese dialect and the written Chinese language as the subordinate into one where the local Chinese dialect and the written Chinese language dominate with the Yoghur language as the subordinate; in the perspective of marriage and heirship system, from a parallel operation of two systems (patrilineal heirship for official marriages and matrilineal heirship system for matrimonial forms through the head-wearing ceremony) to monogamy and patrilineal heirship; in the perspective of means of living, from animal husbandry complemented with hand knitting and camel caravan transporting to agricultural farming complemented with animal husbandry and many others; in the perspective of social organization, from a traditional tribe to a modern country society; in the perspective of political system and social management, from the customs-authority management which combined the dominating headman hereditary system under the tribal union of an imperial dynasty and the subordinating elite influence, to the resource-interest management of party-government departmental system under the ethnic minority autonomy of a nation state; in the perspective of religious faith, from a coexistence of the Gelug Tibetan Buddhism and Shamanism and the devout ancestor worship to the currently prevalent ancestor worship with religions declining and faith weakening; in the perspective of education, from the local-knowledge-oriented education to an official-knowledge-oriented education, in which modern schooling has become the major educational organization instead of the former traditional temple education; the school has replaced the temple as the "knowledge-culture" communication center; at least in the minds of the local people the central role of family education during the children\'s cultural development has also been replaced by schooling.

本研究描述了1907～2007年间，这个乡村社区的多面向的系统变迁：从族群文化的角度而言，从一个以尧乎尔为绝对主体的单一族群文化社区转变为一个以尧乎尔为主体的、有汉、藏、土、蒙古、哈萨克等组成的多元族群文化社区；从语言文字的角度而言，从一个以尧乎尔语和藏文为主，以汉语方言和汉文为辅的社区转变为一个以汉语方言和汉文为主，以尧乎尔语为辅的社区；从婚姻与继嗣制度的角度而言，从一个双系并行(明媒正娶婚行父系继嗣制度，帐房戴头婚行母系继嗣制度)的社区转变为行一夫一妻制和父系继嗣制度的社区；从生计方式的角度看，从一个以畜牧业生产为主，以手工编织和驼队运输为辅的社区转变为一个以农业为主，以牧业为辅的、多种生计方式并存的社区；从社会组织的形态而言，从一个传统部落社会转变为一个现代乡村社会；从政治制度和社会控制的角度而言，从帝制王朝的部落联盟制下头目世袭制为主，户族精英为辅的习俗—权威型控制方式转变为一个民族-国家中民族区域自治制度下以党政科层制的资源—利益型控制方式；从宗教信仰的角度而言，从一个格鲁派藏传佛教和萨满教并存，祖先崇拜之风甚烈的社区转变为寺庙衰落、信仰淡化、惟祖先崇拜仍广为流行的社区；从教育的角度而言，从一个以地方知识教育为主的社区转变为一个以官方知识教育为主的社区，现代学校教育取代了传统寺庙教育成为社区的主要教育组织形式，学校取代寺庙成为"知识—文化"传播的中心，在青少年儿童的文化成长过程中，家庭教养扮演的中心角色，至少在乡民的观念上被学校教育替代。

对20世纪中国家族家庭小说进行系统全面的梳理，我们发现："五四"时期的家族家庭小说文本，父子关系的对立隐喻着传统封建象征秩序下的民族遭际，采用二元对立的叙事模式及家族逆子视角与"俯视"视点；"十七年"时期的家族家庭小说文本，父子关系的共谋谱写着宏大叙事遮蔽下的革命历史，恪守以阶级斗争为中心的叙事语法及全知全能视角与"仰视"视点：新时期以降的家族家庭小说创作，父子关系的解构书写着戏仿与颠覆的历史叙事，创立戏拟与反讽的叙事模式及第一人称"我"的视角与"平视"视点。
