摘要
通过3个品种的胁变过程的分析,表明:1.用向心力和切向力或离心力和切向力进行胁变分析是可行的.2.通过分析认为存在频率、阻尼和相位三种抗性因素.3.通过进一步分析认为阻尼与耐性相关,相位与避性相关,因此可以认为频率、耐性和避性是抗性的三个因素.4.继而认为存在避耐性抗性,避频抗性和耐频抗性三种抗性形式.5.在Levitt抗性理论中只有避耐一种抗性形式。本文突破了这种模式.
In this study, strain process of three varieties was analyzed, results showed that: 1. Centripetal force and tangential force or centrifugal force and tangential force could be used as a strain analysis method. 2. There were three resistance factors i.e. frequency, damping, phase position. 3. Damping was correlated with patience, phase position was correlated with avoidance, indicating that frequency, patience and avoidance were three resistance factors. 4. There were there types of resistance: avoidance and patience, avoidance and frequency, patience and frequency. 5. This paper broke through probably the model which was only one Avoidance and patience type in Levitt resistant theory.
