  2. Our practice is to remove the endosteal side of the graft for two reasons : first, the thin endosteal portion provides a graft to be placed across from the cortical graft ; second, the endosteal surface, being rather rough and irregular, should be removed to ensure good contact of the graft with the host bone

  6. 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。
  7. Thus mechanical properties, heat resistance properties and solvent resistance properties of pu are greatly enhanced. crystal forms of composite materials, surfacial reactivity and adsorption assemble properties of zeolite are discussed in this paper by means of xrd, ftir and tg etc. the test results of xrd prove that mmt can be exfoliated into nanocomposites in pu / mmt, while zeolite keep its original crystal structure in pu / zeolite. the spectras of ftir prove that tdi can graft on the surface of the zeolite

  8. The experiment result discovered the grafting effect of crylic acid and acrylamide were obvious which can be proved by the sem photoes. by the ft - ir testing of the grafted uhmwpe fabric, we discovered that some new polar groups were introduced to the surface. then by the dynamic wetting experiment of the grafted uhmwpe fabric, we concluded that the wetting time was a parabola relation with the graft ratio and the wetting time of the grafted uhmwpe fabric was less than that of untreated fabric. the results showed that after the coradiation grafting, uhmwpe fiber ' s surficial nonreactivity could be improved effectively
