  2. By increasing the h2 dilution ratio, it is found that atomic hydrogen can selectively etch amorphous phase and stabilize crystalline phase. from the study on the distance from substrate to catalyzer, choosing a proper distance can ensure the gas fully decomposed, while a relatively low substrate temperature can cause the nanocrystalline particles to lose mobility and keep their sizes. the pre - carbonization process can enhance the nucleation density and make the growth of high quality nanocrystalline p - sic films much easier

    實驗結果表明：隨著工作氣壓的減小，薄膜的晶粒尺寸有所減小；通過提高氫氣稀釋度，利用原子氫在成膜過程中起的刻蝕作用，可以穩定結晶相併去除雜相；選擇適當的熱絲距離能保證反應氣體充分分解，又使襯底具有較高的過冷度，是形成納米薄膜的重要條件；採用分步碳化法可以提高形核密度，有利於獲得高質量的納米- sic薄膜；襯底施加負偏壓可以明顯提高襯底表面的基團的活性，因負偏壓產生的離子轟擊還能造成高的表面缺陷密度，形成更多的形核位置。
  3. Dlc and a - sic : h films were prepared by the rf glow discharge and the reactive sputtering method respectively. there were two reasons that we chose y rays, ultraviolet ( uv ) photons, and neutrons as radiation sources. one is that y rays, uv photons and neutrons irradiation are serious at outer space and / or nucleus irradiation enviromentthe other is that the study on y rays irradiation on the films is a new and an important directioaotherwisejirnited reports have been made of the investigation on the uv photonsjieutrons irradiation influences on these films

    本文分別採用射頻（ 13 . 56mhz ）等離子體cvd及射頻反應濺射方法制得了dlc及a - sic ： h薄膜。文中主要選擇y射線、紫外光及中子作為輻照源有兩方面的原因：一方面，在外層空間， y射線及紫外光輻射十分嚴重，而在核輻射環境下y射線及中子輻射也不可忽視；另一方面， y射線輻照這兩種薄膜完全是一項開創性的工作，同時國內外對紫外光子、中子與這兩種薄膜作用的研究也很少。
  4. Purpose 1 construction of prokaryotic high expression vector of human platelet factor 4 ( h pf4 ) 2 expression and purification of r h pf4 3 bioassay of r h pf4 methods according to the modulation character of eukaryotic protein expression in prokaryotic cells, we design a pair of particular primers, and construct a prokaryotic expression vector pbv220 - r hpf4 by dna polymerase chain reaction ( pcr ) and dna recombinant technic. the expression plasmid was identified with pcr and dna sequencing. pbv220 - r hpf4 was transformed into e. coli dh5a, bl21 ( de3 ) and induced by increasing the temperature to 42. we identified the expression protein by sds - page and western - blotting
