An ultraviolet subnanosecond pulse train is directly and passively generated from a solid state laser medium ( Ce 3+ ∶ LuLiF 4) pumped by a standard 10 nsec laser.
用一个10ns脉冲激光器泵浦固体激光介质Ce3＋∶LuLiF4，直接地，被动地产生了紫外亚纳秒脉冲序列。
The time-interval measurements are made with two high-resolution ( 10 nsec) digital time-interval counters along with a digital printer to record the data.
用两个分辨率为10毫微秒的时间间隔测定器测量时间差，并用数字打印机来记录测量结果。
The curve of fluorescence decay of ethidium bromide is very near to the answer curve of the instrument. The fluorescence life is 1.18 nsec. But the signal of fluorescence decay of the two complexes is very intensive.
溴化乙锭的萤光衰减曲线按近仪器的响应曲线，萤光寿命为1.18毫微秒，但两种DNA-溴化乙锭复合体的萤光衰减信号非常强烈。
Therefore, tasks are the key to NSEC, and its quality has a direct impact on the overall quality of the textbook.
因此，任务部分是该教材的关键，它的质量对教材的整体质量有着直接影响。
