pek 解釋
白
  1. By static tests, studied the uf characteristics of the uf membranes, which have two kinds of intercept molecular eight, and made from pes, pek, spes and spk ， in treating black liquid from basic straw pulp. the result showed : at the condition of static contacting, the pes and spes spk are polluted by composition of black liquid in a less degree, and the pek is in the heaviest edgree. the sulphonaled membranes with higher negative charge have better uf characteristics of black liquid. the uf membranes characteristics of 20 thousand intercept molecular weight are superior to 50 thousand intercept molecular weight

    通過靜態試驗，研究了兩種截留分子量的聚醚碸、聚醚酮、磺化聚碸/聚醚碸、磺化聚碸/聚醚酮等超濾膜處理堿法草漿黑液的超濾特性，結果表明：靜態接觸條件下，聚醚碸及磺化類膜受黑液組份的污染程度較輕，聚醚酮膜的污染程度最重；荷負電性較高的磺化類膜具有較好的黑液超濾特性；截留分子量2萬的超濾膜特性要優於5萬的膜。

  8. The numerical results in chapter four appear to show that the convergence of the quadratic pe method and the quadratic pe ; method is better than the linear pe method and the linear pek method

    第四章的數值算例表明，二次pe方法和二次pe _ k方法的收斂性比一次pe方法和一次pe _ k方法的收斂性好。
  9. If the proper parameter is chosen, the linear pek method is superior to the linear pe method. ( 2 ) in order to improve the linear pe method and the linear pek method, the quadratic pe method and the quadratic pek method are put forward. then the solvability and the convergence of the two methods are discussed about the hermite positive definite matrix and m - matrix, and the interrelated conclusions are obtained

    （ 2 ）將一次pe方法和一次pe _ k方法改進為二次pe方法和二次pe _ k方法，討論了當系數矩陣a為hermite正定矩陣和m -矩陣時，二次pe方法和二次pe _ k方法的可解性和收斂性等問題，得到了相關的結論。
  10. ( 2 ) on the results of new quadratic pek method, the quadratic epek method is discussed. the convergence of the quadratic epek method is proved in hermite positive definite matrix. then the condition of hermite positive definite matrix is extended to the condition of the positive - definable matrix

    （ 2 ）在新型二次pe _ k方法的基礎上，討論了新型二次pe _ k方法的外插迭代二次epe _ k方法的收斂性，證明了當系數矩陣為對稱正定矩陣時二次epe _ k方法的收斂性，並將在正定矩陣條件下收斂的情形推廣到了可正定化矩陣的情形。
