In order to detect the heat conductivity of preservation material underwater efficiently and accurate-ly, preservation material heat transfer underwater is theoretically analyzed. DPHP( dual-probe heat-pulse) measurement theory and detection technology based on DPHP are studied. Many experiments are done to vali-date the method. The experiments show that the average measure time less than 40 s; the heat conductivity' s precision is ±0.05. Experimental data indicate that the methods can obtain the same results as theoretical a-nalysis. Its speed and precision are highly improved.
