摘　　要：介绍了一种基于可编程逻辑门阵列电路穴FPGA雪,用直接数字频率合成穴DDFS雪技术产生旋转电场的方法。该电场的旋转速度(即频率)和强度(即幅度)能在很大范围内调节,可以广泛应用于医疗、化工、食品、环保等行业中对液态物质进行物理改性处理,以获得新颖的特性,有着很好的经济效益和社会效益。TA method that using the direct digital frequency synthesis(DDFS)produce circumrotating electric field is introduced in this paper.This method depends on the field programmable gate array (FPGA). The frequency and range of the electric field can be adjusted greatly.It is widely used in medical treatment,environmental protection,chemistry industry and foodstuff to obtain some new characteristics,and has gained a good economy benefit and society benefit.
