存在主义作为现代人的生存体验对文学的影响是多方面的。本文从存在诗学角度分析海子诗歌对存在深渊的超越与救赎。海子以神性体验的方式追寻人在大地之上的诗意栖居,通过对人类个体生存悲剧命运的揭示,思考人类和诗歌的命运。虽然最后生存的虚无还是吞噬了海子的心灵,但是身处贫乏时代追问诗人何为的勇气和独特的探索生存秘密的方式使海子诗歌在精神向度上远远超越了同时代的诗人。 相似文献

助推滑翔机设计中的几个主要问题确保所设计的助推滑翔机既能像火箭一样爬升,又能像滑翔机一样下滑,并不是一件容易的事。为实现这点,模型设计者们采用了一些方法,主要有两种:一是移动模型的重心;二是移动气动力面。一些设计者还将这两种方法结合起来。以下是几种常用的方式。 相似文献

This paper uses the concept of stories of peoplehood to examine how the Singapore government has constructed a story of harmony and to consider how this story has influenced two important school subjects focused on civic education: Social Studies and Character and Citizenship Education. Stories of peoplehood, including constitutive, economic and political power stories, play a central role in the political project of people-making which involves defining the nature of membership in a political community and promoting a collective political identity. This study provides an alternative way of conceptualizing the goals and curriculum content of civic education and it also offers an example of how a nation state with a strong Confucian tradition has chosen to address the educational goal of living together through the promotion of values such as social cohesion and community relationships within a story of harmony. The study also shows how Singapore political leaders construct a narrow and limited discourse of harmony within the curricula and use it to legitimize policies that privilege particular groups, limit political freedoms, marginalize groups with less power or status, and circumscribe the kinds of actions a citizen can legitimately take. 相似文献

The fern genus Diplaziopsis C. Chr. of Index Filicum has long been considered as
a monotypic one, with the sole species, D. javanica (B1.) C. Chr. from tropical Asia. In
1906, H. Christ described a second species, Allantodia cavaleriana Christ (=D. cavale-
riana C. Chr.) from Kweichow, West China, but this was since not fully recognized by
fern students in general, being often considered as a variety of the first species. This
is certainly a mistake, as is shown by ample herbarium specimens today. In the recent
work on the genus, the writer has found among the herbarium material two additional
new species from China, thus bringing the genus up to four species in Asia, mainly from
China, where, as it is, the genus has its center of development from the long past.
Phylogenetically, Diplaziopsis C. Chr. represents one of the offshoots from the great
stock of diplazioid ferns, of which the genus Diplazium Sw. constitutes the main body
of the group and from which our genus differs chiefly in its leaves of a thin texture with
reticulated venation, but not so much in its type of indusium as it has generally been
emphasized by most botanists in the past, for, as it is, the type of indusium in Di-
plaziopsis also prevails in many species of Diplazium, for which C. B. Clarke (Trans.
Linn. Soc. ser. 2, Bot. I:495, 1880) created, but really superfluously, a subgenus Pseudal-
lantodia, about which the writer will dwell in another paper in the near future. Suffice
it to say here that the indusium in Diplaziopsis as revealed by the species treated here
is, indeed, typical of diplazioid ferns, only often, as it happens, with its adaxial edge
pressed so tight under the expanding sorus that it is unable to open freely along its upper
free edge and, as a result, its thin vaulted back bursts open from the pressure of the ex-
panding sorus underneath.
As a result of the present study, following four species of the genus have been re-
cognized.
Diplaziopsis javanica (B1.) C. Chr. Ind. Fil. (1905) 227.
Wide spread in tropical Asia, northwardly to Bakbo and the southern part of Yun-
nan, China.
D. cavaleriana (Christ) C. Chr. Ind. Fil. Suppl. I (1913) 25.
Ranges from West China through northern part of Fukien of East China to Japan.
D. intermedia Ching, sp. nov.
Endemic in West China: Mt. Omei, Szechuan, and Kweichow.
D. hainanensis Ching, sp. nov.
In conclusion, it may be pointed out that with the modern plant taxonomy pursued
in a more efficient manner than in the past, and especially by the introduction of the
cytotaxonomic methods, the so-called “monotypic genera”, as conceived by the orthodox
systematists, will continue to prove, to a great extent, to be lack of enough scientific
ground. The fact that the “monotypic genus” of Diplaziopsis C. Chr. is now found to
be a genus of four well-defined species is once again an instance to illustrate the pointat issue. 相似文献

The present paper aims at clarifying the identity of Asplenium varians Wall. and its related species for the forthcoming Flora of China vol. 4. Wide-spread in the northern, north-western and south-western parts of China and adjacent regions and growing in exposed rock crevices is the group of ferns in question, which has hi-
therto been taxonomically confused in the botanical literature. Many distinct and related species were previously identified as Aspl. varians, a most wide-spread fern with very variable fronds which may vary from 10 to 30 cm in height and from simply pinnate to fully bipinnate in the degree of pinnation in a single clump under different habitats. 相似文献

1 知识经济与知识产权制度
社会经济发展史表明,知识产权制度诞生是经济发展的内在必然要求。由于自然资源的稀缺性以及由此引发的对自然资源的争夺,产生了对技术创新的强大社会需求,任何社会都将发生争夺这种需求的竞争,社会要保持经济活动的有序,就必须制定出指导和调节竞争的规则和约定。以动力机械的发明和改进为标志的近代技术革命,促使社会经济的重大发展,也使技术知识本身成为一种资源,一种比自然资源更为稀缺的资源。 相似文献
