Objective To evaluate the clinical efficacy of the percutaneous radiofrequency (RF) ablation in treatment of renal cell carcinoma.
目的评价经皮射频毁损治疗肾细胞癌的临床价值。
2
The distributed parameters of signal path of high frequency relay are the main factors that influence the radiofrequency (rf) performances of relay.
高频继电器信号路径的分布参数是影响继电器射频(RF)性能的主要因素。
3
With coherent detection, radiofrequency (RF) signal can be recovered with simultaneously suppressed second-order distortion and third-order intermodulation.
