摘要：

Electric current leads placed in the vacuum space are often used in cryogenic systems. A complex analysis of the thermal processes in the leads is a difficult problem. Simplifying conditions were determined and a numerical procedure was written for the evaluation of the main heat flows and temperature distribution. The procedure was tested using other available methods and was also verified in several experiments. A satisfactory agreement between the calculated and measured data was found. Importance of the heat radiation in certain lead configurations was found. Some problems arose as regards the analysis of a copper conductor in a special configuration. The solution of several factual problems concerning the current leads design is described and the results are discussed. (C) 2000 Elsevier Science Ltd. All rights reserved.
