摘　　要：偏振特性是光的一个重要性质,具有重要的应用价值.通过分析光的三类偏振态及其偏振度,指出依据电矢量在不同方向上的强度来定义偏振度时的缺陷,明确偏振的物理本质,即是光场中的振动取向有确定的变化规律.The characteristic of polarization is an important property of light, and has an important ap- plication value. By analyzing three types of light polarization states and their polarization degree, the paper pointed out the defect when the degree of polarization was defined according to the strength of the electric field vector in different directions, and indicated clearly the physical nature of polarization. In light field, vibration orientation has definite variation law.
