微波照射法(Microwave Irradiation)已在食品工业方面广泛应用。在医药工业方面,《日本抗菌物质医药品基准》已收载了用高频作为一种照射灭菌法。宇野等提出,对高频灭菌,如谨慎进行,可能用于注射剂的灭菌。以水为主要成份的药液是有双极性的,在交流电场中,因电场时间的变化,使双极发生旋转振动,分子摩擦而产生热量,如(1)式 Microwave Irradiation has been widely used in the food industry. In the pharmaceutical industry, the “Japan Antibiotic Substance Medicines Baseline” has incorporated high frequency as a radiation sterilization method. Uno, etc., proposed for high-frequency sterilization, such as cautious, may be used for injection sterilization. Liquid water as the main component of the liquid is bipolar, in the AC electric field, due to changes in the electric field time, the bipolar rotation vibration, molecular friction and heat, as (1)
