Objective: To observe the needle-knife treatment of cervicogenic headache effects of nerve compression factor in cervical headache pathogenesis.
目的：观察针刀治疗颈源性头痛的效果，探讨皮神经卡压因素在颈源性头痛发病中的作用。
When the pressure becomes very high and temperature very low, the compression factor of the real gas should be considered in the engineering design.
当压力很高、温度很低时工程设计中常引入压缩因子。
It was found that the compression factor and the compression quality factor increased with initial chirp and power, but optimum fiber length decreased.
增大初始啁啾和输入功率可以得到更大的压缩因子，同时最佳光纤长度减小，它们之间基本成线性关系。
It is founded that the compression factor and the compression quality factor increase with initial chirp and power, but optimum fiber length decreases.
结果表明，增大初始啁啾和输入功率可以得到更大的压缩因子，同时最佳光纤长度减小，它们之间基本成线性关系。
When the values of initial chirp and power are small, the compression factor and the compression quality factor don't simultaneously achieve the optimum value.
还发现在初始啁啾值和初始功率比较小时，在最佳光纤长度处，品质因子和压缩因子不是同时达到最大值。
