NSEC

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。

However , NSEC needs to improve the presentation of adjectives in terms of colligation , semantic preference and semantic prosody .

然而，NSEC在呈现形容词的类联接、语义偏向和语义韵方面稍显不足。

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。
