报告题目摘要:
The most important task for magnetic trap plasmas (fusion) is how to confine the high-temperature plasmas in the space-limited reactor as long as possible. Generally, the charged particles move alone the, magnetic lines helically, but at the same time there are also particles and energy which are transported from core outside to boundary. The best and most complete theory to gauge the transport speed (coefficients) in magnetically confined system is the Neoclassical Theory. However, it is found (experimentally) that the transport often exceeds Neoclassical expectations by an order of magnitude or more. This is the so called anomalous transport, which perplex the researchers since several decades. It is currently recognized that the anomalous transport is not caused by "collision effect", but by "collective effect". A totally different theory, other than the collision based Neoclassical Theory, will be needed for describing the collective behavior. The self-organization and dissipative structure might be the most attractive one. The basics and history of the self-organization and dissipative structure are introduced firstly in this report. The anomalous transport in magnetically confined plasmas is then pointed. Some significant achievements on this research field are shown. The unresolved problems are also discussed at end of the report.
