  1. 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。
  2. One avhrr image of the yangtze delta at 13 : 00 on 15th apr., 2003 is used to retrieve the regional parameter such as surface albedo, ndv1, surface emissivity and surface temperature, which is based on regional trait of the yangtze delta to choose different model. all above will give a methodological support to gain the regional surface parameters, what ' s more, it will afford the parameter support to calculate the regional et too

    選取了2003年4月15日13時的avhrr影像，根據長江三角洲區域特點，選擇不同的反演模型，分別對長江三角洲區域地表反照率、歸一化植被指數、地表比輻射系數、地表溫度進行了反演，為區域地表參數的獲取提供了方法支持，也為長江三角洲的區域蒸散量求取提供了參數支持。
