The studies on optical properties and irradiation effect of heavy ion implanted samples are very important from both theoretical and applied view points. in this work, the optical properties and defect structures in xe + - implanted ysz and ni + - implanted al2o3 were studied by using optical spectroscopy, tem, xps and trim 96 calculation. it was found that 1 ) a broad absorption band centered at 522 nm was observed in 1 1016 cm - 2 xe + - implanted ysz
離子注入是一種重要的表面改性技術， ysz （ yttria - stabilizedcubiczirconia ）和- al _ 2o _ 3是兩種性能優良的陶瓷，前者是目前發現的最抗輻照的絕緣體，而後者則是抗輻照最差的絕緣體材料之一，研究重離子注入對其光學性能的影響並以此研究輻照效應，有重要的理論意義和應用價值。 -
Dare ya is not just a documentary about the explits and growth of tem ordinary young men from the estates who just happen to be members of a rap band, but a wake - up call for hong kong
大你這部電影除了簡單而忠實地記錄了本地十個草根青年-樂隊成員的奮斗與成長故事外，也是新世紀的香港照妖鏡。 -
This dissertation is mainly concerned about the radiation of the tem - horn arrays which radiate uwb ( ultra wideband ) pulse, it mainly involves three parts : theory, numerical stimulation and experiment. the uwb antenna is a new research field in the world which has many differences from nb ( narrow band ) antenna. the most difference is that the uwb antenna such as tem - horn radiates nanosecond pulse which has wide frequency spectrum, but the nb antenna radiates single frequency signal
超寬帶天線是一項新興的研究領域，它與窄帶天線有很多不同之處，最根本的不同在於：超寬帶天線例如tem喇叭天線是輻射納秒級短脈沖信號，這種脈沖信號有很寬的頻譜；而窄帶天線大都是輻射單一頻率時諧信號的。
