摘　　要：在介绍两种常见边界条件下流体定性温度确定方法的基础上,提出了一种用积分平均温度确定流体定性温度的方法,这种方法对确定进出口温差比较大的流体物性有更高的精确度。This paper presents a way to determine fluid qualitative temperature with integral average temperature, based on methods on two kinds of common boundary conditio- ns. This new way has greater accuracy of determining fluid property when fluid temperature difference between inlet and outlet is great.

关 键 词：定性温度 物性参数 换热 传热 流体对流换热
