简介：UV就是UltravioletRay的英文简称，也称紫光线光固化上光。UV固化技术自20世纪60年代发明以来，到20世纪末已经得到了普遍应用。在我国，UV印刷和UV上光已经被广泛应用在铝箔纸和铝箔卡纸印刷，磁卡印刷，商业印刷，金属印刷，食品包装印刷（饮料杯，快餐盒等)，不干胶印刷等领域，尤其在丝网印刷（玻璃，木制品，塑料薄膜等非吸收性材料)领域更是大显身手。UV上光技术的应用前景非常广阔。

简介：因为紫外可见的吸收度察觉者不能避免的一般多波长源于光的紧张变化的噪音和飘移采购原料，双横梁多波长紫外可见的察觉者基于电荷耦合器件被设计。在它通过chopper以后，轻来源的光线被横梁splitter划分成一条信号光线和一条引用光线。信号光线照耀进样品房间。通过样品房间的信号光线失败到集中它到被一个凹面栅栏在电荷耦合器件的一部分上想象的槽上的一面凹面镜子上。参考光线被凹面栅栏在槽以后在电荷耦合器件的另外的部分上想象。信号光谱，引用光谱和电荷耦合器件的黑暗水流能在光系统的合作下面在一样的电荷耦合器件上被测量并且补助电路。为由使用参考光谱和电荷耦合器件的黑暗水流的信号光谱的即时赔偿能有效地压抑察觉者的噪音和飘移。短期的噪音是10?5AU和飘移是10?4AU/h。CLC数字TN366文件代码A

简介：信息化战争是体系间的对抗,涉及的战场对象多且活动关系复杂,态势理解难度大幅增加,传统的单目标融合方法已无法满足大规模联合作战的情报保障需求。分析了多维多源异构情报大数据下态势感知的背景和需求,探讨了思维导图和知识图谱等方法,提出了目标关系融合技术,并给出了应用案例设计,实现了目标融合由“点式”到“链式”的转变,从而支撑对敌方意图的深度感知。

简介：近日．爱克发公司宣布自己的UV固化油墨已经被允许使用在Xaar的OmniDot760打印机头上．而这个打印头是由这两家公司联合开发的。爱克发公司为Xaar打印头开发了一系列UV固化油墨，并能用这些油墨生产出多种高质量且持久性强的室内外彩色印刷品。
