The tobacco-specific nitrosamine 4--1-(3-pyridyl)-1-butanol is present in the urine of tobacco users and, at lower concentrations, in the urine of nonsmokers exposed to secondhand smoke.

烟草特有的亚硝胺4--1-(3-吡啶)-1-丁醇存在于吸烟者和被动吸二手烟的非吸烟者人群的尿液中，只是被动吸二手烟的非吸烟者人群尿液中的浓度更小。

This paper selected 7 samples and did a series of experiments about the isochermal absorption and fixation of phosphorus to select one or several suitable crucible residue to study compound fertilizer. The result declare that the absorbed phosphorus and the fixability of the No2,Noll and No21 is smaller than the other samples,for the more the desorpability of the three samples get to 30%- 40%.

为选择合适的含硅熔渣用于复合肥，本文对含硅溶渣样品进行了对磷的吸附与解吸和对磷的固定的测定，实验结果表明，2号、11号、21号三个渣样对磷的吸附量与固定率均比其他四个供试渣样少得多，且此三个渣样解吸率达到了30％～40％。

The moisture sorption isotherms of the dried beef added sorbitol with different amounts were made to determine the reduction degree of water activity in this paper.

通过在牛肉干中添加不同比例的山梨糖醇，然后对制成的产品进行等温吸湿线的测定，了解其降低水分活度的效果，并对所测定的等温吸湿线进行了数值回归。

The moisture sorption isotherm s of the dried beef added sorbitol with different amounts were made to determine the reduction degree of water activity in this paper.

通过在牛肉干中添加不同比例的山梨糖醇，然后对制成的产品进行等温吸湿线的测定，了解其降低水分活度的效果，并对所测定的等温吸湿线进行了数值回归。

Several profile suction pipes with different double slots are developed and applied to spin cotton yarns of same fineness. Though comparing the structure and performance of this cotton yarn with that of yarns by the compact spinning or the Siro spinning, the advantages of compact Siro spinning are further indicated.

用自行研制的具有不同吸风双槽的紧密赛络纺吸风管分别纺制相同线密度的棉纱，并与相同工艺条件下的紧密纺和赛络纺纱线就纱线结构与性能进行比较分析，进一步说明紧密赛络纺纱工艺的优越性。

Experimental result showed that under the wavelength of 460 nm,there was good linear relation between absorbency and content of SO42-;and stationary time that absorbency value needed became longer along with the increase of sample quantity of phosphoric acid.When absorbency become stationary,there is good linear relation between the phosphoric acid sample quantity and the content ofSO42-.So the content of SO42- can be adjusted by turning the sample quantity to make it in scope of standard curve.

实验结果表明，在波长为460 nm处，硫酸根含量与吸光度成良好的线性关系；随着磷酸取样量的增加，吸光度达到稳定值所需的时间相应增加，稳定后磷酸取样量与硫酸根含量成良好线性关系，因此实验过程中可通过调整磷酸的取样量来调节硫酸根含量，使之在标准曲线的测定范围内。

The pump body consists of suction chamber, liquid storage chamber, turbination chamber, liquid return port, gas-liquid separation chamber, etc. After the pump starts normally, the impeller will suck the liquid in the suction chamber and the air in the inlet line so that the both can mix fully in the impeller. Due to the centrifugal force, the liquid along with the gas flows towards the outer edge of the turbination chamber and then a belt of white foam with a certain thickness and a liquid ring with high-speed rotation come into being on the outer edge of the impeller.

泵体由吸入室、储液室、涡卷室、回液孔、气液分离室等到组成，泵正常起动后，叶轮将吸入室所存的液体及吸入管路中的空气一起吸入，并在叶轮内得以完全混合，在离心力的作用下，液体夹带着气体向涡卷室外缘流动，在叶轮的外缘上形成有一定厚度的白色泡沫及高速旋转液环。

The demulsification mechanism of PAMAM belongs to displacing mechanism. Acylamino groups of PAMAM of integral having strong polarity can take place chemical adsorption with the materials of strong polarity in the exterior of oil drop and be participated in into the membrane, which will result in adsorbed crude surfactant and other active materials to be partially displaced and reduce the intensity of interfacial film between oil and water.

其机理是由于整代的PAMAM具有强极性的酰胺基团，能与油滴表面的强极性的物质发生化学吸咐作用，参与成膜，能把原来吸咐的天然活性剂分子和其它活性物质部分顶替，削弱油水界面膜强度。

The seed of Camelina sativa contain 5.67% jelly which envelopes the seed and could absorb 181.31 times water. This might be the main cause that the seeds of Camelina sativa absorb more water in more rapid speed than wheat, which can explain the drought-resistance of Camelina sativa.

亚麻荠种子的外层胶质占种子总重的5.67%，可吸收181.31倍的水分，使种子在最初10min内即可吸收相当于自身重量8倍的水分，浸泡24h后吸水量达到10倍左右；而小麦种子浸泡24h后吸水量只有54.7%，据此认为这可能是亚麻荠种子抗旱性较强的原因。

In near futurewe are going to focus on the infectious model of monogeneans of Epinephelus spp. in different culture system and their host specificity model by linking the ecological and molecular data.

下一步的研究目标是以石斑鱼的寄生单殖吸虫为研究对象在研究该基因的功能的基础上探讨单殖吸虫高宿主特异性的机制。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.
