rfa 中文意思是什麼

rfa 解釋
放射纖維蛋白測定
  1. The reasons which were suggestive of a causal relationship between hemocholecyst and radiofrequency ablation ( rfa ) included : the close proximity of the ablated tumor to the gallbladder, and the " chronological sequence of events "

    由於燒灼位置靠近膽囊與發生時間的先後順序，因而創建射頻燒灼而導致膽囊出血之因果關聯。
  2. Patients were followed for clinical toxicities, alterations in model for end - stage - liver disease ( meld ) score, tumor response, downstaging to rfa, resection, transplantation, and survival

    隨訪觀察患者的臨床毒性，晚期肝臟疾病模型（ meld ）評分變化，腫瘤反應，爭取降期可射頻消融（ rfa ） ，切除，肝移植和存活率。
  3. Raman fiber amplifier （ rfa ） is a kind of optical amplifier that can amplify signal light directly through nonlinear interaction of high intensity pump and signal light in fiber. whereas the spectrum of raman gain coefficient of optical fiber is not flat, the gain of signal light with different wavelength induced by a single pump is rather different, when wavelength division multiplexing ( wdm ) signal light is amplified by a single pump, the gain spectrum of the wdm signal light is not flat. the flatness of the wdm signal light has important impact on the optical signal - to - noise ratio ( osnr )

    拉曼光纖放大器（ ramanfiberamplifier ，簡稱rfa ）利用高強度的泵浦光與信號光在光纖中的非線性相互作用實現信號光的直接放大，但是由於光纖的拉曼增益系數譜很不平坦，所以同一泵浦光源對不同波長信號光的增益就存在很大的差別，因此，用單泵浦光源來放大波分復用（ wavelengthdivisionmulti - plexing ，簡稱wdm ）信號光時，各信號光的增益值就有很大差異， wdm信號增益的平坦度對光信噪比（ opticalsignal - noiseratio ，簡稱osnr ）有重要影響。
  4. Rfa raman fiber amplifier

    拉曼光纖放大器
  5. Rfa railway freight association

    鐵道貨物協會
  6. Conclusion : these data suggest that intra - arterial ( 90 ) y microspheres can be used as a bridge to transplantation, surgical resection, or rfa

    結論：這些資料表明，動脈內的90釔玻璃微球治療可成為達到肝移植，外科切除，或射頻消融（ rfa ）的橋梁。
