  1. The samples were joined with heat rate of 200 / min, 260 / min, 370 / min

    加熱相比,接觸面處原子加快。
  2. 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

    我們對接枝反應中的各個因素如:單體濃度、劑量劑量以及反應時間進行了研究分析,結果表明:單體濃度和劑量是反應的兩個主要影響因素,它們對反應速的影響指數分別為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;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最後在整個膜體中形成接枝產物。
  3. This paper mainly studies on the thermal diffusivity and thermal conductivity by ptr method

    本文主要用光熱( ptr )技術理論來研究材料的熱系數和熱導
  4. We give ptr ' s amplitude and phase signal of one dimension based on the theory of ptr, discuss the ptr ' s signal ' s frequency characteristic, and a method for measuring thermal diffusivity of opaque materials is introduced. then, we study on anisotropic materials " thermal conductivity, the temperature field and thermal conductivity tensor of anisotropic materials is theoretically deduced from the theory of ptr, and is proved by the experiment

    從光熱理論出發,推導出一維情況下ptr信號的振幅和位相表達式,討論了光熱信號的頻特性,介紹了一種用ptr技術測量不透明材料熱系數的優化方法;接著研究分析了各向異性介質受調制激光束照下產生的光熱信號,在理論上推導出各向異性介質的溫度場以及熱導張量並給予一定的實驗驗證。
