压力蒸汽灭菌器内冷空气的排出程度可影响灭菌的效果。现沿用的“压力蒸汽灭菌器内空气排出程度与温度关系表”(表1),对指导正确使用压力蒸汽灭菌器具有重要意义。但该表在计算中,忽略了冷空气受热后压力增加的因素,因此大部分数值均有出入。压力蒸汽灭菌器在灭菌过程中是恒容过程。当加热介质为水运一单一组分时,处 The level of expelled cold air inside the pressure steam sterilizer can affect the effectiveness of the sterilization. The existing “Table of the relationship between the degree of air discharge in a pressure steam sterilizer and the temperature” (Table 1) is of great importance in guiding the proper use of a pressure steam sterilizer. However, the table in the calculation, ignoring the cold air heating pressure increases after the factor, so most of the values ​​are discrepancies. Pressure steam sterilizer in the sterilization process is a constant volume process. When the heating medium is a single component of water transport, at
