In this paper, tobacco-specific nitrosamines levels of Yunnan flue-cured type cigarettes were determined by a developed GC-TEA method, including TSNAs in tabcco fillers ,mainstream and sidestream smoke.The observed TSNAs values ranged from 85.73ng/g to 418.03ng/g in tobacco fillers and 8.2 ng/g to 29.71ng/cigarette in mainstream smoke and in sidestream smoke ranged from 415.87ng/cigarette to 895.84ng/cigarette.

中文摘要：本文采用GC/TEA技术对云南烤烟型卷烟中的烟草特有亚硝胺进行了研究。48种卷烟的分析显示：烟丝和主流烟气TSNAs变化范围分别是85.73 ～418.03 ng/g和8.2～29.71 ng/支，其中NAT+NAB的含量最高，NNN和NNK含量较接近；侧流烟气TSNAs变化范围是415.87～895.84ng/支，含量明显高于烟丝和主流烟气，NNK所占比例平均达84.29%。

In the present work,Cu nanoparticles with an average size of 20-50 nm were dispersed in diesel fuel oil . A injection pump plunger was in-situ repaired on a 12PSDB75 fuel injection pump by applying auto-reconditioning function of Cu nanoparticles. Mophologies and typicle element distributions of the plunger piston surface before and after repair were analyzed by scanning electron microscopy and energy dispersive X-ray spectroscopy.
