14KV,0.0067uF. One advantage of these capacitors is that they have a self healing dielectric, so they can run closer to their maximum design voltage and suffer voltage surges without any permanent damage; if a dielectric punch trough occurs the metalized layer on the polypropylene dielectric vaporizes around the arc and the capacitor continues to work with only a slight decrease in its capacitance...

这些电容器的一个优点是，它们具有自我修复介质，这样他们就可以运行更接近其最大设计的电压和受害而没有任何永久性损害电压浪涌，如果发生介质冲槽上一层金属化聚丙烯弧周围介质蒸发和电容继续工作，只有在其电容略有下降。。。

The sequences of repeats and anchor nucleates are arbitrarily selected.Coupled with the separation of amplification products on a polyacrylamide or agarose gels,ISSR amplification can reveal a much larger number of fragments per primer than RAPD.It is concluded that ISSR technique provides a quick,reliable and highly informative system for DNA fingerprinting.

重复序列和锚定碱基是随机选择的，扩增产物经聚丙烯酰胺或琼脂糖凝胶电泳分离后，每个引物可以产生比RAPD方法更多的扩增片段，因此，ISSR标记是一种快速、可靠、可以提供有关基因组丰富信息的DNA指纹技术。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.
