- 在资料复制机中，一种色调安排与原件相反的复制件。对照positive。In a document copying machine, a copy having tonal arrangements opposite to those on the original.
- 进行了X射线衍射(XRD)分析 ,电阻温度系数 (RTC)和Hall系数测试 ,并进行Raman散射的微观分析实验 ,认为该半导体薄膜可用作室温工作的红外测辐射热计 (Bolometer)灵敏元 .The microstructure of YBCO film was analyzed by XRD and the resistance temperature coefficient(RTC) values, Hall effect and Raman shift of YBCO film were measured. It is believed that the semiconducting YBCO thin film will act as new sensor elements of IR bolometer working at room temperature.
