【Abstract】 In this paper the progress of pressure rising for cryogenic liquid in the heated pipe was analyzed and the critical mass flow velocity in the transfer process was calculated. According to the experimental data in some literatures, the calculation formula of the pressure in this transfer process was proposed, The ways to reduce the maximum pressure were also proposed in this paper, It provided the reference to determine the parameter in transferring cryogenic liquid and to design the pipes.更多还原
