A series of experiments at several levels of relative humidity and radiation dose rates was carried out using spores of Bacillus subtilis var. niger to evaluate the effect of heat alone, radiation alone, and a combination of heat and radiation. Combined heat and radiation treatment of microorganisms yields a destruction rate greater than the additive rates of the independence agents. The synergistic mechanism shows a proportional dependency on radiation dose rate an Arrhenius dependency on temperature, and a dependency on relative humidity. Maximum synergism occurs under conditions where heat and radiation individually destroy microorganisms at approximately equal rates. Larger synergistic advantage is possible at low relative humidities rather than at high relative humidities.
使用枯草芽孢杆菌黑色变种的孢子，在几个相对湿度和辐射剂量率水平上进行了一系列实验，以评估单独加热、单独辐射以及加热与辐射组合的效果。对微生物进行加热与辐射联合处理所产生的破坏率大于各独立因素的累加破坏率。协同作用机制表现出对辐射剂量率的比例依赖性、对温度的阿伦尼乌斯依赖性以及对相对湿度的依赖性。在加热和辐射单独以大致相同的速率破坏微生物的条件下会出现最大协同作用。在低相对湿度而非高相对湿度条件下可能具有更大的协同优势。
