What the lysine does, Dougherty and colleagues report online this week in Nature, is change the shape of the brain receptor's box, effectively making its negative charge more accessible to nicotine--a situation known as a cation-pi interaction.

Dougherty 他们在这个星期的 Nature 网站上报道说，它能够改变大脑受体"口袋"的形状，有效地使其负电荷更好与尼古丁相作用，就是所谓的阳离子—π作用( a cation-pi interaction )。

After mainenervations being drawn out and being dried for 4 hours at 60℃,1156 samples of tobacco leaves from different tobacco producing-area were made into powder (≤0.13 mm). Reducing sugar, total sugar, nicotine, nitrogen, potassium and chlorine of more than 1000 samples from different tobacco producing-area were determined with classical chemical or instrumental methods. By scanning these samples with Fourier transform Near Infrared spectrometer (MARIXT-I produced by Bucker) we obtained their spectrograms, pretreated the spectrograms with a chemometrics software (OPUS 5.5) to debase the noises influence on spectrum information, and built a chemometrics model by means of Partial Least2Squares. The chemometric model was optimized some times and validated with some other samples.

选取全国不同烟草生产地区的1156余烟叶样品，采用相同的预处理条件(去处主脉，60℃烘干4小时)，处理成40目待测粉末样品，采用行业经典的化学分析方法或准确可靠仪器方法测定其常规成分含量，在条件一致(20℃～24℃，环境湿度≤40 RH%)的实验室环境中，使用市场上主流的傅立叶变换红外光谱仪(德国BRUKER公司生产的MARIXT-I)上进行图谱扫描，采用OPUS5.5化学计量学软件，对光谱进行适当的预处理，减弱以至于消除各种噪声对光谱信息的影响，用偏最小二乘回归法建立常规成分预测模型，并进行了反复优化和未知样品模型外验证。

Early conversion stimulation and converter identification method was used to analyze the nicotine conversion rate of three burley hybrids and their parents.

采用烟碱转化株早期诱导鉴别方法，对3个白肋烟杂交种及其亲本的烟碱转化率进行了分析。

Burley tobaccos have a low carbohydrate content of nitrogenous materials, nicotine, and nonvolatile acids.

白勒烟 含有较低的碳水化合物和含氮化合物，烟碱和非挥发性酸。

CCA indicates that there are strong integrated correlation between mainstream smoke and the physical and chemical properties, where canonical variable U representing information of mainstream smoke is mainly contributed by TPM, tar, nicotine, vapor, vapor content and puff times; canonical variable V representing physical and chemical information of cigarettes is mainly contributed by ventilation rate, close resistance, cigarettes weight and total sugar, total organic chlorine etc, where ventilation rate plays an important role.

典型相关分析表明：卷烟主流烟气与物理化学信息间存在显著的整体相关，其中反映主流烟气信息的U典型变量主要来自总粒相物、焦油、烟碱、水分、水分含率及抽吸口数的贡献；反映物理、化学指标信息的V典型变量主要来自稀释率、闭式吸阻、单支重及总糖、氯等化学指标的贡献，其中稀释率的作用最大。

The results showed that plant height increasing speed was significantly slow at the former and middle stage when K level was above 180 kg/hm2.On the contrary,the height of case-hardened plant improved markedly.When the K level was above 135 kg/hm2,the stem girth and maximal leaf area differed significantly as compared with CK,so did LAI.Yield and product value per unit area took the first place when 180 kg/hm2 potassium was used.Average price and proportion of middle and first grade tobacco leaf of 225 kg/hm2 potassium treatment were the highest as compared with other treatments and CK.Four economic characters of the two treatments differed at obvious significant level as companied with CK.The total sugar and K2O were increased,nicotine, total N,protein and Cl- were decreased with increased K levels.The potassium lacked symptom was alleviated with increased K levels,no symptoms was observed when 180 kg/hm2 potassium was used,the degree of weather infected fleck was decreased when the K levels was increased.

结果表明，在烟株生长前中期，当施钾量达到180 kg/hm2以上时，株高增长显著变慢，而定型株高则显著增高；茎围和最大叶的面积在施用135 kg/hm2以上的处理与CK之间的差异性达到极显著水平，叶面积指数也存在显著差异；单位面积产量和产值以施用180 kg/hm2的处理居首位，中上等烟比例和均价以施用225kg/hm2的处理最高，这两种处理的以上4个经济性状与CK之间存在极显著性差异；烟叶中的总糖和K2O含量随施钾量的增加而上升，烟碱、总氮、蛋白质和C-含量则下降；缺钾症状随施钾量增加而减轻，至施用180kg/hm2时已无缺钾症状；烟叶气候斑的发生程度也随施钾水平的提高而减轻。

Consequently, genetic polymorphisms in both nicotine metabolism and dopamine catabolism genes may influence smoking behavior, and interact with each other resulting in risk modulation.

因此，在尼古丁代谢和多巴胺分解中的基因多态性可能会影响吸烟行为，它们的相互作用导致风险的调节。

As is known to all, cigarets contain nicotine which is harmful to people, but many smokers can't give it up. Therefore, getting rid of this habit is a big problem for them. And phenomena can happen quite ofen that the cigarets come back to some smokers life again after several days' suspending.

众所周知，香烟中含有对人体有害的物质尼古丁，但许多烟民都难以摆脱它的束缚，戒烟即成为他们的一大难题，经常会有此类现象发生：在戒烟几天后，香烟再次回到戒烟者的生活中。

I can not make it blossom and suits me

我不能让树为我开花
