【Abstract】 The significance of measuring oil thermal conductivity in scientific research and engineering design was briefly dealt with,the current measuring methods of the thermal conductivity of liquid were systematically reviewed,for example,theoretical derivation,steady and non steady state method etc.,the advantages and disadvantages of these methods were reviewed and analyzed. Finally,the existing problems and the development trend were pointed out in measuring oil thermal conductivity. The measuring practice showed that transient plane source method was exact and credible,with great application prospect.更多还原
