低碳经济背景下西南沿边民族地区城镇化模式反思
The Reflection towards the Urbanization Patterns of Southwest Border Ethnic Minority Areas under the Background of Low Carbon Economy
 [PDF]

王新哲,
Urbanization and Land Use (ULU) , 2016, DOI: 10.12677/ULU.2016.44006
Abstract:
低碳经济是以低能耗、低排放、低污染为基础的经济模式,民族地区城镇化是实现民族地区经济发展的必由之路。在低碳经济成为未来主要发展方式的大背景下,西南沿边民族地区已有的城镇化模式所带来的负面影响越来越严重,低碳城镇化发展道路已经成为西南沿边民族地区的必然选择,面对边界“屏蔽效应”、缺乏产业支撑、建设资金匮乏等城镇发展困境,建议西南沿边民族地区政府引导增强低碳意识、引进低碳技术、发展低碳产业、拓宽融资渠道、加强国际合作。
The low-carbon economy is a kind of economic development model which is based on low energy consumption, low emissions and low pollution, and the urbanization is the only route which must be passed to realize the economic development in ethnic minority regions. For the low-carbon economy development model will become the main development method in the future, the negative effect brought by the existing urbanization pattern of southwest border ethnic areas becomes more and more serious, as a result, the low-carbon development path of urbanization has become the inevitable choice of the southwest border ethnic areas. In the face of some developing predicaments, such as the “shielding effect”, the lack of industry support and construction funds, we should guide the governments of the southwest border ethnic areas to increase the awareness of low carbon development, bring in the low carbon technology, develop the low carbon industry, broaden the financing channels, and strengthen the international cooperation.
我国城市经济影响区域系统的初步分析

地理学报 , 1987, DOI: 10.11821/xb198704003
Abstract: 城市经济影响能力取决于城市投资集聚能力、市场集聚规模和技术、经济的水平状况。对15个经济变量所作的主因子分析表明我国城市经济活动的差异主要受城市经济活动规模的制约。技术、经济水平差异有一定的影响,但影响不大。目前我国已形成5级区域经济影响中心,七个一级城市经济影响区域。

核聚变理论再探及聚变堆的自持燃烧
The Investigation of Fusion Theory and Self-Sustained Combustion of the Fusion Reactor
 [PDF]

树勤, 传华
Nuclear Science and Technology (NST) , 2015, DOI: 10.12677/NST.2015.32005
Abstract:
根据修正后的狭义相对论,得出通电流等离子体的箍缩效应,本质上是尺缩效应,其并不能对聚变反应起促进作用。对电磁辐射理论的质疑,指出目前的电磁辐射理论并不符合麦克斯韦方程组,再结合聚变实验结果,推测目前的电磁辐射理论低估了聚变堆的辐射能。以上两点揭示了目前核聚变理论与实验形成巨大差异的原因,并得出目前的聚变装置不能实现聚变堆自持燃烧的结论。由此提出了对目前磁约束聚变装置在功能上的改进,将聚变堆包层第一壁设计为具有反射镜的功能,使辐射能重新返回,以达到聚变堆的自加热目的。最后探讨了磁镜与环流器相组合的聚变装置新型,阐述了该装置具有其它磁约束装置不可比拟的优势。
Based on the corrected special theory of relativity, the pinch effect has been proved to be length contraction effects for plasma like galvanization. It will not accelerate the fusion reaction. By questioning the electromagnetic radiation theory, the current theory has been approved that it does not fit the Maxwell’s equation. Combined with the testing results of the fusion reaction, the current electromagnetic radiation theory underestimated the radiation power of the fusion reactor. As mentioned above, it revealed the reasons causing the great difference between the current fusion theory and the testing results, and concluded that the current fusion reactor cannot achieve self-sustained combustion. So the improvements on the magnetic confinement devices have been suggested. For achieving self-heating of the fusion reactor, the first wall of the fusion reactor must be designed to reflect the radiation. At last, the new device which combined magnetic mirror and Tokamak has been discussed and its superiority has been approved over the rest of magnetic con-finement devices.
国际市场营销渠道简介

世界科学技术-中医药现代化 , 1999,
Abstract: 产品变为商品,即制造出来的产品走上市场。中医药产品走向世界,进入国际市场,概括说来有三种渠道:一是间接出口;二是直接出口;三是国外生产。二、间接出口是企业将产品卖给国内的出口商或委托国内的外贸代理机构,由其经销出口业务。在我国,间接出口主要是通过对外.
类病毒的双向聚丙烯酰胺凝胶电泳检测技术
,
微生物学通报 , 1985,
Abstract: 类病毒为已知的最小的致病因子,只含核酸,不含外壳蛋白。类病毒能在若干高等植物上引起重要病害,在一些经济作物上造成损失。防治类病毒侵染,主要靠早期诊断。可以用聚丙烯酰胺凝胶电泳法,生物学方法,以及分子杂交等方法检测类病毒。用生物学方法检测,即接种一定的鉴别寄主,周期长,费时费力;用分子杂交方法须用放射性同位素,探针的制备也较困难,在一般的实验室不大容易进行;以往
比较类病毒和卫星RNA的复制及其某些性质

微生物学通报 , 1986,
Abstract: 一、类病毒、拟病毒和卫星RNA 1967—1971年,美国的Diener发现马铃薯纺锤块茎病是由分子量仅为1.2×10~5的RNA引起的,称作类病毒。类病毒的发现是生物学史上的一个重要事件,揭示了一类比病毒更小的病原的本质。这样小的核酸引入到适当的寄主后,能独立复制和致病,开拓了研究生命物
