description The invention discloses a double-screw rotor end face tooth profile design method suitable for a high-temperature working condition. The method comprises the following steps of: a, obtaining theoretical thermal state three-dimensional models of a first screw rotor and a second screw rotor from a specified normal temperature to a specified high temperature to obtain a rotor center distance variablequantity; b, obtaining a theoretical thermal state end surface profile of a first screw rotor at the specified high temperature; C, obtaining an actual thermal state end face profile of the second screw rotor according to the theoretical thermal state end face profile and the rotor center distance variation; D, obtaining an actual cold state three-dimensional model of the second screw rotor whenthe second screw rotor is cooled to a specified normal temperature from a specified high temperature; E, obtaining an actual cold-state end surface profile of the second screw rotor; And f, when the actual hot end face molded
