基于无限大介质中的径向一维非稳态导热分析所确立的血液热导率的瞬态热线法原理和前期工作中存在的缺陷〔１〕，对测试装置中的线热源、测温方法及检测技术等进行了改进，改善了装置的性能，提高了测试的准确性。用正常人体的新鲜血液进行了测试，并对测试结果的不确定度作了分析，不确定度不超过２．５％。
Based on the transient hot-line method of blood thermal conductivity established by the one-dimensional radial one-dimensional unsteady thermal analysis in infinite medium and the defects in the previous work [1], the linear heat source, temperature measurement method And testing techniques have been improved to improve the performance of the device and improve the accuracy of the test. The test was conducted with fresh blood from normal human subjects and the uncertainty of test results was analyzed with an uncertainty of no more than 2.5%.
