As a kind of structure view element with the highest life attributes, plants can make the modern agricultural science and technology park have more vitality. Therefore, combined with the case study of Jiuxi Agricultural Science and Technology Park, the modern agricultural science and technology park planning was analyzed based on the perspective of plant experience, with the aim to provide bases for the planning of featured modern leisure science and technology park.展开更多

The nuclear power plants are such sources. However, a great number of the developing countries do not possess developed large capacity power systems. Moreover, currently in the developing countries, there are no highly skilled personnel to provide construction and reliable and safe operation of the nuclear plants, which are complex and potentially hazardous systems. In some countries, the level of terroristic threat is extremely high. For that reason, there are specific requirements to the nuclear PSs intended for use in the developing countries. In the presented report, the specific requirements which must be met by the NPT proposed for use in developing countries are formulated, basic statements of the SVBR-100 concept are presented, design and principal scheme of the reactor fa-ility are described, major characteristics of SVBR-100 are summarized.展开更多
