在某种意义上,“公共财产神圣不可侵犯”的宪法宣言彰显了社会主义对资本主义的批判;“私有财产权不可侵犯”的神圣入宪隐喻了宪政的理性。私有财产权与公有财产权的均衡宪制是一种“社会能量守恒定律”的宪政隐喻。这两种基本财产权的均衡态势既有静态的平衡,也有动态的衡平,并展现为“一明两暗”的对立形态和以人为目的的终极关怀。由于这种均衡态势在各国宪法中展现的侧重点不同,而成为各国形成不同的宪政观念的重要原因之一,这便是宪政的隐喻所在。在三种不同模式的宪法中检讨这一隐喻,为当下解构、建构和创新中国的宪政理念与制度具有重大意义。 相似文献

战术移动通信网的网络拓扑结构随战场环境的变化而变化,为此网络拓扑结构具有重组的能力,网络拓扑重组后必须进行链路频道的重新分配,文中提出的频道分配技术是在避免同频道干扰条件下任一频道可在全网内多次重复使用,以提高频道的重复利用率,同时分析了该情况下网络至少应拥有的频道数,以保证网络有足够的频道供分配。 相似文献

本文从《水浒传》生成史的角度,将《水浒传》的成书和作品主题的嬗变联系起来,论证梁山故事在流传过程中不断出现的传奇色彩和归正倾向。它是封建社会全社会被压迫者与有志之士的反抗与追求的“交响曲”,是对封建社会后期现实的一种“全景式的综合反映”。 相似文献

Advance results from the 1982 census of China are presented based on a 10 percent sample. Sections are included on age distribution, centenarians, marriage patterns, educational status, and the labor force. Several characteristics of China's population are described in this article, based on a 10% sampling tabulation of the production teams and resident groups of the whole country. Data are included for 100,380,000 people. The proportion of the population aged 0-14 is 33.60%, which marks a decline from figures in the 1964 census (40%). This decline is attributed to family planning and population control efforts. The median age is 22.91 years, which is 2.71 years older than that in the 1964 census. The % of the population aged 15-64 rose from 55.7% in 1964 to 61.5%. The dependency ratio dropped from 79.4% (1964) to 62.6%. There were 3,765 centenarians as of July, 1982; the overwhelming majority live in villages, and most (94.77%) are illiterate or semiliterate. The number of female centenarians is 2.4 times that of males. Marriages are comparatively stable in China. 63.6% of the population aged 15 and over are married, and .59% are divorced. The % of the population remaining single after age 50 is .21% for females, 2.97% for males. The average 1st marriage age is 22.80 years for females and 25.49 years for males. 60.35% of the people have had primary education or above; .44% are college graduates. In 1964, 33.58% of the population illiterate or semiliterate. At present, among people aged 12 and over, 31.90% are illiterate or semiliterate. The rural illiteracy rate is more than twice the urban rate. 51.94% of the total population is employed. Of these, 92.08% are engaged in manual labor. Males exceed females in all professions and occupations. The median age of the employed population is 30.84 years. The level of education among the employed is relatively low: 28.26% are illiterate or semiliterate, and 34.35% have had primary education only. 相似文献

The China Family Planning Association was set up in May 1980 as a nongovernmental organization under the leadership of the Communist Party of China. Funds come from the government, international organizations, and individual or community donations. 13 branches have been established so far. The Association has contributed to publicity, education, and research: members have given lectures on family planning, genetics, and population theory, and have helped develop contraceptives. The lectures on population problems have been published. In addition, the Association's periodical "Ren Sheng" is published bimonthly, and has a circulation of 125,000. Meeting have been convened for the exchange of information and experience among family planning workers. The Association organized tripartite seminars with IPPF and JOICFP in June and October, 1983. Under the auspices of the Association, 8 trainees have been sent to the David Owen Center in the United Kingdom for a Year's study, and 1 trainee was sent to the London School of Hygiene and Tropical Medicine. The Association was accepted as a full member of the IPPF at the conference held in Nairobi, Kenya, in November, 1983. 相似文献
