With the increase of plasma density dispersion curve is shifted upward significantly . Because the shift speed of the lower cutoff frequency for TM mode is greater than that of the upper cut-off frequency bandpass frequency range reduced gradually and the dispersion curves become flattened . 4 .

随着等离子体密度的增加色散曲线明显 上移，由于TM模式的下截止频率 上移的速度大于上截止频率 上移的速度，导致通带的频率范围减小，色散曲线变平坦。

Brachial deep artery can be used for vascular pedicle bone ( film ) disc upward shift technology the treatment of humerus period of nonunion or bone defect . 5 .

肱深动脉可用于血管蒂骨（膜）瓣 向 上 移位技术，治疗肱骨中、上段骨不连或骨缺损。
