Determination of Tobacco-Specific Nitrosamines in Cigarette Smoke with Liquid Chromatography-Tandem Mass Spectrometry

A model of heat transfer from smoke to liquid copper is established based on principle of energy balance. The average temperature and the intensity of heat transfer of smoke with different air surplus coefficients are calculated by using the model.

根据能量平衡原理，建立烟气对铜液的传热模型，并对不同空气过剩系数下的烟气平均温度和传热强度进行计算。

The "filter" has a tiny, microprocessor-controlled atomizer that vaporizes a mixture of propylene glycol-the stuff used in theatrical smoke machines-and liquid nicotine when you inhale.

过滤嘴有一个非常小的，微处理器控制的雾化器，当你吸入时，蒸发丙烯和乙二醇的混合物-戏剧性的用在吸烟机中的原料-和液态尼古丁。

Our liquid never leaves the U.S. We get no e-liquid from China.

我们的液体从未离开美国。我们没有任何来自中国的电子烟液。

The F.D.A. does not yet have standards for e-liquids, but many of the Chinese companies say they make them in labs in the United States that have passed F.D.A. quality-control standards.

FDA目前还没有关于电子烟液的标准，但许多中国企业都声称，他们是在美国的一些达到FDA质量控制标准的实验室制造这些液体的。

Among the concerns is that some smaller manufacturers use poor-quality insulation paint on the heating coils, paint that could prove dangerous if it leached into the e-liquids.

有人担心，一些规模较小的制造商会在加热线圈上使用质量很差的绝缘涂料，倘若这种涂料渗入电子烟液，可能会很危险。

Results As treated with original solutions or 1/ 2 dilution of DMSO cigarette smoke solutions only, the Viability of cells was below 80%, but it was beyond 80% when treated with PBS solutions.

结果DMSO烟液原液及其1/2稀释液染毒的细胞存活率低于80%，而PBS烟液染毒的细胞存活率均高于80%。

Stephen fell asleep owing to the heat from the wood fires in the tobacco barn, and when he awoke the fire was almost out.
