The Basic Ocean Law (BOL) and Basic Ocean Plan (BLP) are important guarantee for the maritime strategy of Japan, which has established a complete policy system for the development of marine science and technology. On the other hand, the Japanese Government has started some major marine strategies and plans to promote the BLP. In this paper, the marine science and technology plans launched by the Japanese Government and its participation in the international cooperative research projects were introduced. The research of Japan Marine Science and Technology Center and the University of Tokyo Institute of Oceanography in the long-term planning and focus on the layout features, deep sea research technology layout, contents and advanced equipment were analyzed. At last, some recommendations for China’s development on marine science and technology were proposed, such as strengthening the legislation work and process, carrying out research and development of marine infrastructure with independent intellectual property rights, actively participating in international large-scale ocean plan, improving the discourse right and enhancing national maritime awareness and suggestions and so on.  相似文献   

Ozone and climate governance: An implausible path dependence     

《Comptes Rendus Geoscience》2018,350(7):435-441

Many observers and commentators have used the case of ozone science and politics as a role model for climate science and politics. Two crucial assumptions underpin this view: (1) that science drives policymaking, and (2) that a unified, international science assessment is essential to provide “one voice” of science that speaks to policymakers. I will argue that these assumptions are theoretically problematic and empirically questionable. We should realize that both cases, ozone and climate, are profoundly different and only have superficial similarities. Ozone science developed late, but efforts to protect the ozone layer happened swiftly. The relation between carbon dioxide and climate change has been studied for many decades, but efforts to control global warming have failed so far. I will discuss the linear model of the science-policy relationship and use the typology of tame and wicked problems to explain this stark difference.  相似文献   

科学与主权：晚清民国时期西方学者在中国的地质学考察     

孙承晟 《地质论评》2021,67(5):67060015-67060015

晚清随着中国国门洞开,西方学者、传教士、商人、探险家以“科学无国界”的旗号,将中国视为一个巨大的“露天博物馆”,纷纷来华进行各种科学考察。其中比较著名的如庞佩利、李希霍芬、塞切尼、奥勃鲁切夫、维理士、安得思以及斯文·赫定等,在中国先后组织了多次系统的考察,在地质学等领域取得了许多影响深远的成果。这些考察不仅丰富了西方地质学家对中国地质的认识,对之后的中国学者也颇多裨益。民国以后,西人的考察活动激起了中国学者的民族主义反弹,不断遭遇中国学者的主权诉求,尤其是斯文·赫定组织的西北考察成为其中的一个标志性事件。在民间团体的努力下,政府对外国人在中国的考察活动逐渐作出了明确的法律限制,中国学者亦自发开展独立的地质学考察和研究。  相似文献

五强溪水电站左岸船闸边坡开挖监控设计的理论与实践   总被引：12，自引：7，他引：12  

杨志法  柯天河 《工程地质学报》1995,3(2):1-11

五强溪水电站船闸左岸边坡，是由前震旦系的Ｐｔ１（主要为千枚状板岩）和Ｐｔ２（主要为砂岩、板岩）组成。因断层穿插，岩体破碎，边坡稳定性很差。为确保边坡在开挖施工期的安全，作者根据工程地质力学和系统科学相结合的方法，对之进行监控设计，取得了成功。  相似文献   

关于成矿系列的结构   总被引：6，自引：1，他引：6  

翟裕生  熊永良 《地球科学》1987,(4)

成矿系列是一个自然系统,它由若干矿床成因类型组成。各矿床类型间的时空结构关系表现为各类型间的“共生性”、“过渡性”和“重叠性”;其物质结构关系表现为“互补性”.本文按系统论观点,分析了上述结构,提出长江中下游铁铜成矿系列的新模式,并指出研究成矿系列的结构对预测矿产的重要意义.  相似文献   

Low frequency waves in plasmas with spatially varying electron temperature     

P. Guio  S. Børve  H. L. Pécseli  J. Trulsen 《Annales Geophysicae》2001,18(12):1613-1622

Low frequency electrostatic waves are studied in magnetized plasmas with an electron temperature which varies with position in a direction perpendicular to the magnetic field. For wave frequencies below the ion cyclotron frequency, the waves need not follow any definite dispersion relation. Instead a band of phase velocities is allowed, with a range of variation depending on the maximum and minimum values of the electron temperature. Simple model equations are obtained for the general case which can be solved to give the spatial variation of a harmonically time varying potential. A simple analytical model for the phenomenon is presented and the results are supported by numerical simulations carried out in a 2.5-dimensional particle-in-cell numerical simulation. We find that when the electron temperature is striated along B₀ and low frequency waves (_ci) are excited in this environment, then the intensity of these low frequency waves will be striated in a manner following the electron temperature striations. High frequency ion acoustic waves (_ci) will on the other hand have a spatially more uniform intensity distribution.  相似文献
