Tft - lcd has the characteristics of little consumption , low driving voltage , non x ray radiation , apt to realize mass production , light and portable etc . it has dominated the market of fpd now Tft - lcd以其微功耗、低工作电压、无x射线辐射、易于实现大规模集成化生产、轻巧便携等一系列特点,率先进入市场并不断拓宽其应用领域,现已占据lcd显示市场的主流位置。
For liquid xe aerosol spray target , important lpp characteristics , such as laser - to - euv conversion efficiency , euv radiation absorption , debris production by target material erosion or deposition , are studied in detail , a 13 . 4nm conversion efficiency of 0 . 75 % into 2 % bandwidth and 2 steradian emission solid angle is achieved at 0 . 5mm laser - nozzle distance 在实验上，建成了一套高光谱分辨率和高灵敏度的软x射线脉冲辐射测量装置。测量了co _ 2 、 o _ 2 、 cf _ 4 、 kr和xe液体微滴喷射靶lpp光源在6 20nm波段的软x射线辐射光谱。
Now the method has application at large . because the laser - produced plasmas are rapidly varying , temporal resolution of spectral features is important to investigation of x - ray radiancy evolvement with time , many dynamic plasma processes and radiation transport . soft x - ray time - resolved diagnosis technology have had quiet great progress since from sixty " s end to seventy " s early 由于激光等离子体变化快，且其x射线辐射的时间特性包含有丰富的物理信息，因此时间分辨的x射线辐射特性诊断是研究激光等离子x射线辐射随时间的演变，各种动力学过程和辐射输运等物理问题所必需的关键诊断技术。
At present we have made great efforts on radiation statistics of proton - flare " s x - ray , especially hard x - ray , and character of hard x - ray in the process of proton accelerating , and we have gotten solar x - ray " s character before proton event and bring forward forecasting method which is actualized and proved in fy - 2 satellite " s alarming system of proton event 目前我们已经在质子加速过程中的硬x射线特征、质子耀斑x射线辐射统计(特别是硬x射线特征)等方面作了系统的工作，已获得质子事件前兆的太阳x射线特征，并提出了预报方法，已在fy - 2卫星质子报警系统中加以了实施和验证。
