pfl 中文意思是什麼

pfl 解釋
動液面
  1. 3. a fast algorithm is proposed for computing the linear complexity of a binary sequence with period p ? and generalized one for determining the linear complexity of a sequence with period pfl over gf ( q )

    提出了一個計算周期為p ~ n的二元序列的線性復雜度的快速演算法，並推廣為確定gf （ q ）上周期為p ~ n的序列線性復雜度的快速演算法。
  2. In the second experiment, by introducing helical blumlein line as pfl, we can obtain a square pulse with 260ns pulse duration

    首次將具有螺旋結構的blumlein脈沖形成線進行了實驗，取得了較好的研究成果。
  3. Pfl ( persistent functional language ) is a simple functional language with database extensions

    Pfl是一種簡單函數語言，它帶有數據庫擴展。
  4. Thus by using pressured water as dielectrics, the energy density of the energy system could be enhanced notablely and the pfl could be miniaturized too

    這一結果不僅有利於脈沖形成線的小型化，還能提高以水為儲能介質的儲能系統的儲能密度。
  5. As for high - energy linear induction accelerator, miniaturizing pulse - forming line ( pfl ) is helpful to minify the size of the massive pulsed power system. at the same time, wealth and space could be economized

    同時脈沖形成線小型化對於一臺大型直線感應加速器來說，不僅有利於減小其龐大的脈沖功率系統，而且節省了大量的財力資源和空間體積。
  6. But if we using the same size blumlein line as pfl, we can only get a square pulse with 31ns pulse duration. this experiment results show that replacing the intermediate conductor of blumlein line by helical conductor can get long pulse

    實驗表明採用螺旋blumlein型脈沖形成線我們得到負載上的方波脈沖的脈寬為260ns ，而同樣長的blumlein線在負載上只能得到31ns的方波。也就是說螺旋blumlein線在原理上是可得到長脈沖的。
  7. 5. a fast algorithm for determining the linear complexity and the minimal polynomial of a sequence with period 2pfl over gf ( q ) is proposed, and a new algorithm for determining the linear complexity of a sequence with period pfl over gf ( p ? ) is introduced

    提出一個計算gf （ q ）上周期為2p ~ n序列的線性復雜度和極小多項式的快速演算法；提出一個計算gf （ p ~ m ）上周期為p ~ n的序列的線性復雜度的新演算法。
