利用铀矿物的荧光性质鉴定铀矿物是一种有效的方法。这是指常温下的荧光性质。前人曾对某些铀矿物的荧光性质进行过升温过程的研究,但对降温过程的荧光性质未作研究。最近我们对一些铀矿物在加热和降温过程中的荧光性质进行了研究。除不同的铀矿物其荧光消失温度不同外,荧光强度,荧光颜色等也随温度的变化而变化,更有意义的是当降温时,有 The use of uranium minerals to identify uranium minerals is an effective method. This refers to the fluorescent properties at room temperature. Previous studies on the fluorescence properties of some uranium minerals have been studied, but the fluorescence properties of the cooling process have not been studied. Recently we have studied the fluorescence properties of some uranium minerals during heating and cooling. In addition to different uranium minerals disappear at different fluorescence temperatures, the fluorescence intensity, fluorescence color, etc. also change with the temperature changes, more significant when the cooling, there
