Summary

THE DEPENDENCE OF THE GAS FLOW RATE ON THE CROSS-SECTIONAL AREA IS DERIVED FROM THE HEAT BALANCE EQUATIONS. TWO CURVES ARE ACQUIRED, ONE RELATING TO THE OPTIMUM AREA, AND THE OTHER TO THE CORRESPONDING TEMPERATURE GRADIENT AT THE COLD END. THE PRODUCT OF THE UTILIZATION COEFFICIENT OF THE COLDNESS TOGETHER WITH THE TEMPERATURE DIFFERENCE IS THE INDEPENDENT VARIABLE FROM WHICH THE GRAPHIC CHANGES OF THE MINIMUM GAS FLOW RATE UNDER VARIOUS SITUATIONS WOULD BE NOTED. CURVES OF ONE-DIMENSIONAL TEMPERATURE DISTRIBUTION OF A LEAD UNDER DIFFERENT CONDITIONS COULD BE DRAWN UP. LASTLY, THE DESIGNING PRINCIPLE OF A LEAD WITH NON-CONSTANT CROSS-SECTIONAL AREA IS DISCUSSED.
