绝处能生     

王石 《少年文摘》2011,(7)

1995年,我正当壮年,万科地产也登上中国地产龙头之位,医生却告诉我:你的腰椎长了血管瘤。若再如此忙碌好动,血管一破,你的下半身就得瘫痪了。我问:那我该如何应对呢?医生说:多静少动,最好坐轮椅。我说:那可不成,还没瘫痪就坐轮椅,怕是不瘫痪也吓瘫痪了。我不怕瘫痪,等真瘫痪了再坐轮椅也不迟。  相似文献   

西藏高原热量资源的地带性分布及非地带性分布规律的探讨     

普布次仁 《西藏科技》1997,(1):9-13,22

文中利用前人提出的山区热量资源分析方法，定量分析了西藏高原热量资源随纬度，经度，海拔高度等地理因子的地带性分布规律及由于非地带性因子的影响而产生的非地带性规律，得出高原面热量资源呈冬夏皆降温，冬夏皆增温，冬增温夏降温以及冬降温夏增温四种非地带性分布规律。  相似文献

刘远明  边巴次仁  陈华 《西藏科技》2005,(4):35-38

2002年5月，西藏高原大气环境科学研究所建成EOS／MODIS卫星资料接收站，2004年9月该接收站又被纳入国家MODIS数据共享平台，至此完成了中国西部地区EOS／MODIS卫星资料接收、处理与传输一整套先进、完善系统的建立。本文主要讲述了EOS／MODIS卫星资料接收、处理与传输的机制和流程以及规范了相关操作并总结了天线出错解决办法，为其它地区EOS／MODIS业务的投入提供了样板。  相似文献   

当大地披上绿装的时候     

李立志 《语文世界(高中版)》2008,(12)

我做了一个梦。梦中,我把心给失落啦!心失落在哪儿呢?是在黄河清澄的浪花里,是在珠穆朗玛峰盈壑的碧绿里,还是在塞外戈壁滩的翡翠里?我自己也弄不清楚。我只能凭记忆,重温旧梦,把失落的心找回来。  相似文献   

高原传说——青藏高原之吐蕃王朝     

《青海科技》2014,(2):73-75

<正>公元6世纪,在西藏高原,藏族历史上著名的英雄人物松赞干布继承其父朗日松赞的遗愿,以卓越的政治远见和军事才能,实现和巩固了西藏高原的统一事业。吐蕃王朝兴起于西藏山南地区,对于藏族人民来讲,吐蕃王朝是一个极具光辉的时代。西藏高原的统一、藏文的创制、佛教文化的传入、尼泊尔和大唐公主入藏等这些影响西藏至今的历史,都是吐蕃时期的历史事件。可以说,吐蕃王朝的300年是整个西藏历史发展中,最精彩和影响最广的一段传奇般的历史。  相似文献

因湖得名的青海     

夏天 《初中生辅导》2008,(Z5):92-94

青海省简称青,因境内有青海湖,故得名青海省。青海湖古称"西海",又称"鲜水"或"鲜海"。蒙语称"库库诺尔",藏语称"错温波",意为"青色的海"、"蓝色的海洋"。由于青海湖一带早先属于卑禾羌的牧地,所以又叫"卑禾羌海",汉代  相似文献   

西藏高原植物区系中特有属的研究     

Ni Zhi-Cheng  Cheng Shu-Zhi 《中国科学院研究生院学报》1987,25(6):417-429

The Xizang (Tibetan) flora with numerous endemics is of importance in Chi- nese flora.   According to recent statistics there are in Xizang 27 genera of  spermatophytes endemic to China, being only 2.25% percent of the total number of genera in the Xizang flora. Four of them are regarded as palaeoendemics (14.81%) and the others as neoendemics (85.19%). These endemic genera, of 30 species and 3 varieties, belong to 17 families, of which, Umbelli- ferae contains 6 genera, 7 species and 3 varieties; Compositae has 6 genera and 7 species, and Gentianaceae 1 genus and 2 species.  All the other families each comprises one genus with a single species.       The cosmopolitan families together comprising 14 genera with 15 species have the highest perecentage (52.92%) and the tropical ones (5 families, 5 genera with 5 species) come to the next (29.42%), followed by the temperate ones (3 families, 10 genera with 10 species) (17.66%). It shows that these endemic genera are obviously related to the tropical flora and temperate one in essence.        According to the number of species, the genera endemic to China and occurring in Xi- zang flora may be grouped as fallows. Monotypic endemic ones 14 (51.85%) Ditypic endemic ones 6 (22.22%) Oligotypic endemic ones 4 (14.81%) Small endemic ones 3 (11.11%)        The formation of the endemic genera is correlated with the topography, climate and en- vironmental conditions, and they may have resulted from the diversification in geography and climatic influence for a long time.  The southeastern part of Xizang Plateau is of very diverse ecological conditions, with the adequate precipitation, which may explain the concentration of these endemic genera in this region.        The largest similarity coefficient (38.30%) of the genera endemic to China and occurring in Xizang is with those in Qinghai Plateau, next, with those in Yunnan and in Sichuan pro- vinces (both 27.60%), which shows that these endemic genera are related to the floras of the regions mentioned above.        The difference in the horizontal distribution of these endemic genera is obviously between the southern and northern parts of Xizang Plateau.  The vertical distribution of the genera is also rather obvious, from 800 m to 5200 m above sea level, but concentrated in the zone of 3000 m to 4500 mm.  Therefore their occurrence in Xizang is not only affected by the historical environmental conditions but also controlled by the horizontal and vertical distribution.      The origin and evolution of some endemic genera, such as Psammosilene, Parateropyrum, Sphaerotylos, Salweenia, Ajaniopsis, Xizangia, Sinoleontopodium, are discussed in this paper.      Parateropyrum, a monotypic palaeotropic endemic, belongs to the tribe Atraphaxideae in- cluding Atraphaxis, Calligonum and Pteropyrum.  It may be a comparatively advanced group in the tribe, and is closely related to the genus Pteropyrum  which is  distributed in western Asia.  The genus Parapteropyrum has possibly survived as a palaetropic-tertiary  relic in this region.      Sphaerotylos, a member of the subtribe Sphaerotylinae, the tribe Boehmerieae in the family Urticaceae, is a comparatively primitive genus in the tribe Boehmerieae so far known.  As the other subtribes, such as Boehmerinae, Sarconchlamydinae, Orecnidinae and Maoutinae, are dis- tributed in the tropics, rarely in the subtropics, the genus is no doubt a palaetropic -tertiary relic.      Sinoleontopodium, belonging to the tribe lnuleae in Compositae, is also related to the ge- nus Leontopodium.  It is probable that the genus Sinoleontopodium arised later than the other.       We come to the conclusion that the southern part of Xizang Plateau is also one of thecentres of the origin and differentiation of genera endemic to China.  相似文献
