开发《大事记》信息资源 创建“大事检索系统”

据笔者所知，各地档案部门大都承担了当月大事记的编写工作，也有的将历史大事记汇编成册。如何开发利用大事记中丰富的信息资源，满足社会各界的查询需要，已成为档案工作者目前必须面对的课题。为此笔者提出了创建“大事检索系统”的构想。一、建立“大事检索系统”的必要性１．“大事检索系统”是精神文明建设成果的具体体现。考察一个城市是否文明，不仅要看其有没有发达的物质文明建设成果，还要看其有没有高质量的精神文明建设成果。“大事检索系统”满足了人们探索历史的精神生活需要，是精神文明建设成果的具体体现。２．为党和政府…     

高空的窃听能手

常规战争中,敌对双方常常捉"舌头"(即俘虏对方人员)来了解对方战术意图、兵力部署及武器装备等情报.随着航天技术的发展,人们采用更先进的方式,即利用人造地球卫星窃取常规手段难以获得的敌方情报.     

美国多元性科学政策制度的形成及其对美国大学科学研究的影响

二战结束前夕,美国联邦政府根据战时的经验试图建立一个独立的联邦科学政策机构,以资助美国的科学研究和制订美国的科学政策。但战后爆发的冷战致使美国形成了由多个联邦机构组成的多元性科学政策制度。这一制度对美国大学科学研究产生了重要影响:它为美国大学科学研究提供了多渠道的经费来源,加剧了科学资源在美国大学之间分配的马太效应,极大地促进了美国大学研究能力的提高。     

中国省域居民生活能源消费的空间效应研究

本文基于2008—2012年中国30个省域为研究对象,从Bayes空间计量的角度研究省域之间生活能源消费的空间效应,并分析不同因素对居民生活能源消费的影响。研究结果表明:中国省域居民能源消费存在显著的空间自相关,多数省域的居民能源消费在空间上呈现高-高和低-低集聚;人口规模是影响居民能源消费最重要的影响因素,其次是居民消费支出和能源消费强度;从当期效应来看,各变量对居民能源消费的直接效应和总效应均显著为正,因此,降低能源消费需要控制人口规模向城市转移的增长速度、降低能源消费强度、引导和改善居民消费结构。     

芍药属的研究(1)——国产几个野生种核型的报道

In the present paper 8 species with 15 populations of the genus Paeonia L. (if P. papaveracea and P. japonica are recognised as species) were collected from Sichuan, Shaanxi and Hebei provinces (see the Appendix for detail of the materials).  The micrographs of their somatic metaphase (also Mii in the case of P.veitchii) are shown in Plates 1-4, the karyo- type formulae, ranges of chromosome length and classification of karyotypes according to Steb- bins (1971) are shown in Table 5: the idiograms in Figs. 1-2, and the parameters of chromo- somes in Table 1-4.  The essential points are mentioned as follows:        (1)   Chromosomes of the various species in the section Modan have so far been examined and they are all diploid, the two species in the section Onaepia are also diploid, and thus tetraploids exist only in the section Paeonia.        (2)  Chromosomes in the genus Paeonia are relatively stable except for the differentiation of ploidy.  The karyotypes (Table 1-4) show no differences among different taxa in Sect. Modan and the same can also be said about the taxa in Sect. Paeonia (Table 1).  Not only are the karyotypes very similar, but also among the members within  either section have the same parameters of chromosomes, and, differences, if occur, are not statistically significant. Between the two sections, however, the situation is different. The arm ratios of the first pairs of chromosomes in Sect. Modan are 1.53, 1.52 and 1.48 (Table 1), but those in Sect. Paeonia are 1.12-1.28 (Table 2-4), 95% confidence limits are 1.46-1.60 for the section Modan and 1.07-1.28 (1.21-1.35 only for PB85078) for the section Paeonia, not overlapping, which indi- cates that the two sections have differentiated in respect of the first pairs of chromosomes.        (3)The population PB85024, which belongs to the P. obovata complex, has a karyotype of 2B (stebbins, 1971), which is a new one in the genus Paeonia. This karyotype is a stable one, for several individuals in the population are uniform in this respect, which shows that Steb- bins’ (1971) generalization that all the species in Paeonia have 2A does not hold true.        (4)  Three populations of P. obovata complex studied in this work from Sichuan and Shaanxi are all tetraploids, and one from Hebei is a diploid.  From the present work and the previcus reports, the materials from Japan and Korea, no matter whether flowers are pink or white, are diploids, those from Heilongjiang Province (with both pink and white flowers) (Liu Ming-yuan, personal communication) and from Heibei Province (with pink flowers) in China are also diploids, the one from Sakhalin (pink flowers) is tetraploid, those from Priamur of the Soviet Union are a tetraploid (with white flowers) and a diploid (with pink flowers), and those from Shaanxi (the Qinling Range) and western Sichuan (with both pink and white flowers) are all tetraploids.  As far as we have now known, ploidy in this parti- cular complex is correlated with the geographical distribution: diploids are found in the cen- tral part, tetraploids occur in the northern limits, and in the south  letraploids are the only cytotype.      (5)  The materials of P. mairei from western Sichuan and Shaanxi (the Qinling Range) are found all to be tetraploids, which shows that two cytotypes, diploid and tetraploid, exist in this  species,  but the geographical distribution pattern of these two cytotypes is to be revealed in the future investigation.

家园的衰朽——巴金与岛崎藤村的同名小说《家》比较研究

中国现代文学大师巴金的小说《家》与日本近代自然主义作家岛崎藤村的同名小说《家》在中日文学史上分别占有重要地位。两部作品在相同题材和主题背后,隐藏着同中有异的文化结构。两位作家虽采用了不同的表现方法,但都从自传体角度阐释了封建家族制度的罪恶与根源,揭示了封建家族制度必然走向灭亡的命运,表现出不同的文化形态和内涵。巴金的《家》承载着儒家文化的精髓,岛崎藤村的《家》则包含着神道与儒教相融合的多元文化的神韵。
