| 6 | Optimal representation of multivariate functions or data in visualizable low-dimensional spaces显示文摘It is intended to find the best representation of high-dimensional functions or multivariate data in L2(W) with fewest number of terms, each of them is a combination of one-variable function. A system of nonlinear integral equations has been derived as an eigenvalue problem of gradient operator in the said space. It proved that the complete set of eigenfunctions generated by the gradient operator constitutes anorthonormal system, and any function of L2(W) can beexpanded with fewest terms and exponential rapidity of convergence. It is also proved as a corollary, thegreatest eigenvalue of the integral operators hasmultiplicity 1 if the dimension of the underlying space nn = 2, 4 and 6. | SONG Jian Chinese Academy of Engineering, Beijing 100038, China | 2001 | Chinese Science Bulletin2001,46,16: | 1 |

| 9 | Green ICT Impact on Energy Conservation and Emission Reduction显示文摘The direct and indirect effect of ICT on energy conservation and emission reduction is described. The energy consumption per unit GDP in the ICT industry is lower than that in other industries. The application of ICT in such fi elds as industrial design, manufacturing, management, logistics, sales and service can be helpful for energy conservation and emission reduction in the industrial and transportations industry; however, the issue of energy waste and environmental pollution caused by voluminous deployment of ICT products should never be overlooked. This paper presents the lat- est development of communications products in energy conservation and exemplifi es the roles of ICT in energy conservation and consumption reduction. The issue of electromagnetic radiation of ICT products and the recycling and reuse of e-wastes are explored. | Wu Hequan Chinese Academy of Engineering, Beijing, 100088, China | 2008 | China Communications2008,5,3: | 1 |

| 20 | Mechanism and control of convective heat transfer——Coordination of velocity and heat flow fields显示文摘A second look has been given at the mechanism of convective heat transfer based on the analogy between convection and conduction with heat sources. The strength of convective heat transfer depends not only on the fluid velocity and fluid properties, but also on the coordination of fluid velocity and heat flow fields. Hence, based on the included angle of velocity and temperature gradient vectors, the presence of fluid motion may enhance or reduce heat transfer. With this concept, the known heat transfer phenomena may be understood in a deeper way. More important is that some novel approaches of heat transfer control can be developed. | QUO ZengyuanDepartment of Engineering Mechanics, Tsinghua University, Beijing 100084, China | 2001 | Chinese Science Bulletin2001,46,7: | 60 |
