  1. The membrane properties were found to be dependent upon the content of styrene. the membrane physic - chemical properties compare to nafion 117 except that their chemical stability has to be further improved to make them acceptable for practical use in the proton exchange membrane fuel cell. the proton transport through the membrane follows the " liquid - like " proton conductivity mechanism y and the water balance is important for the working condition of the fuel cell

    對磺化膜的研究分析表明：膜的性能參數如離子交換容量、吸水率、水合系數、形體穩定性、導電性能、化學與熱穩定性等依賴于膜中苯乙烯含量，且接枝苯乙烯相互間的位阻效應對膜性能影響很大；膜的性能可與nafion膜相比較；質子在膜中的傳導遵循「似液體」質子傳導機理；電滲析與擴散作用使膜保持水平衡。
  2. According to the observed experiments that the na2feo4 solution with the same concentration and volume were decomposed by the same area of different membrane, we learned the order of the decomposing rate of na2feo4 caused by different membranes : soapnated cellulose acetate > vinylon > polypropylene polyvinyl chloride = polyethylene microfiber glass mat

    從觀察等面積的隔膜引起同濃度同體積的na _ 2feo _ 4溶液的分解實驗可知，不同隔膜材料引起na _ 2feo _ 4溶液分解速率從大到小的順序是，皂化再生纖維素膜維尼綸無紡布改性聚丙烯膜聚氯乙烯膜輻射接枝聚乙烯膜復合玻璃纖維氈。
  3. When they were respectively used as separator in zn / k2feo4 battery, the percent of capacity of the cathode active material na2feo4 were : microfiber glass mat ' s : 93 % ; polyethylene ' s : 68 % ; polypropylene ' s : 56 % ; polyvinyl chloride ' s : 47 % ; vinylon ' s : 38 % ; soapnated cellulose acetate ' s : 24 %. although five of them ( not concluding soapnated cellulose acetate ) had very weak or weaker reductivity as separator in super - iron battery, for which th ey were more suitable to being separator in super - iron battery

    作為隔膜用於zn k _ 2feo _ 4實驗電池，正極活性物質k _ 2feo _ 4的放電容量效率分別為復合玻璃纖維膜93 、輻射接枝聚乙烯膜68 、改性聚丙烯微孔膜56 、聚氯乙烯微孔膜47 、維尼綸無紡布38 、皂化再生纖維素膜24 。
  4. The content of styrene was found to be dependent on the investigated grafting conditions, of which the dose rate and monomer concentration were the major conditions, and the dependence of the initial rate of grafting on the dose rate and the monomer concentration was found to be of 0. 4286 and 1. 1662 orders, respectively. the results indicate that the grafting reaction is competitive and the copolymerization and the graft - copolymerization are existing at the same time. the grafting proceeds by the so - called front mechanism in which the grafting starts at the surface of the films and moves toward the middle of the film by successive diffusion of the styrene through the grafted layers

    我們對輻射接枝反應中的各個因素如：單體濃度、輻射劑量率、輻射劑量以及反應時間進行了研究分析，結果表明：單體濃度和劑量率是反應的兩個主要影響因素，它們對反應速率的影響指數分別為1 . 1662和0 . 4269 ；反應的動力學方程為： rg k [ d ] ~ （ 0 . 4269 ） [ m ] ~ （ 1 . 1662 ） ；認為接枝反應是一競爭反應，單體的均聚反應和在聚合物上的接枝反應同時存在，單體濃度的高低決定著競爭反應的方向；輻射接枝反應是從聚合物表面開始的，隨著溶劑的溶脹和單體的擴散最後在整個膜體中形成接枝產物。
  5. In the system the effects of photoinitiator and monomer concentration on grafting are not distinct, while photo - reduction time, uv irradiated polymerization time and uv light intensity have more effects on grafting yield

    實驗發現，光敏劑濃度對接枝率有一定影響；光還原時間增加，接枝率明顯增加；聚合前期接枝率提高較快，反應後期增加緩慢；紫外光照射強度的改變會影響接枝率。
