为了深入研究电流变体中电压阀值(Ec )产生的机理，我们设计了一种全新的测试方法——饱和电压法，并用此方法明确地证实了电压阀值(Ec1和Ec2)的存在，同时对此作出了解释；而且，我们还对两种典型的电流变模型在不同电流变体中的适用性作出了定义。计算机模拟的结果分别给出了两个对应于电压阀值Ec1和Ec2的序参量φ1=1.5和φ2=4.5。

For better knowing the mechanism of Ec(threshold field) in ER fluids， a new testing method，Saturated Electric Fie ld(SEF) was designed. The exist of Ec1 and Ec2 was clearly p roved and explained．Furthennore，the fitness of two well-known model for ER in different ER systems was defined．The computer simulation also gave out two ord er parameter (φ1＝1．5 and φ2＝4．5, which corresp ond well to Ec1 and Ec2, respectively.
