After extraction by ethanol and purification by cationic ion-exchange column, a method of using reversed-phase high-performance liquid chromatography and precolumn derivatization with o-phthalaldehyde and 9-fiuorenylmethylchloroformate is employed for determination of free amino acids in tobacco . This method assures that amino acids with amino and imino groups can be determined simultaneously. The results of duplication experiment and recovery experiment are acceptable.

本试验用乙醇提取烟叶中的游离氨基酸，并用阳离子交换树脂纯化，再用邻苯二甲醛、氯甲酸芴甲酯联合柱前衍生、反相高效液相色谱分析测定了烟叶中的游离氨基酸，该方法能同时测定烟叶中的带氨基和亚氨基基团的氨基酸，并且分析方法的重现性和回收率均令人满意。

We, then, following the Holy Fathers, all with one consent, teach men to confess the one and same Son, our Lord Jesus Christ, the same perfect in Godhead and also perfect in manhood; truly God and truly man, of a reasonable soul and body; consubstantial with the Father according to the Godhead, and consubstantial to us according to the Manhood; in all things like unto us, without sin; begotten before all ages of the Father of the Father according to the Godhead, and in these latter days, for us and for our salvation, born of the Virgin Mary, the Mother of God, according to the Manhood; one and the same Christ, Son, Lord, Only-begotten, to be acknowledged in two natures, inconfusedly, unchangeably, indivisibly, inseparably; the distinction of natures by no means taken away by the union, but rather the property of each nature being preserved, and occuring in one Person and one Subsistance, not parted or divided into two persons, but one and the same Son, and only begotten, God the Word, the Lord Jesus Christ, as the prophets from the beginning concerning him, and the Lord Jesus Christ himself has taught us, and the Creed of the holy Fathers has handed down to us.

我们跟随圣教父，同心合意教人认识同一位子，我们的主耶稣基督，是神性完全、人性亦完全者；他真是上帝，也真是人，具有理性的灵魂，也具有身体；按神性说，他与父同体；按人性说，他与我们同体；在凡事上与我们一样，只是没有罪；按神性说，在万世之前，为父所生；按人性说，在晚进时日，为求拯救我们，由上帝之母，童女马利亚所生；是同一基督，是子，是主，是独生的，具有二性，不相混乱，不相交换，不能分开，不能离散；二性的区别不因联合而消失；各性的特点反得以保存，会合于一个位格，一个实质之内；而非分离成为两个位格，却是同一位子，独生的，道上帝，主耶稣基督；正如众先知论到他自始所宣讲的，主耶稣基督自己所教训我们的，诸圣教父的信经所传给我们的。

In addition, our works also indicate that MC-ICPMS technique shows a good potential on Re-Os isotopic measurement. 2. A new method for the determination of low Re-Os abundances and ~(187)Os/~(188)Os in a natural rock sample by MC-ICP-MS has been established in our laboratory. Rock samples were digested in inverse aqua regia in sealed Carius tube for 24 hours at 230°C, then Os was separated from the matrix by CCl_4 solvent extraction, and further purification by microdistillation.

建立了Re-Os同位素样品的化学分离和纯化方法以及MC-ICPMS质谱测定方法：岩石样品的Re和Os化学分离方法是采用Carius管溶样法，结合四氯化碳萃取以及氢溴酸反萃取的方法分离出Os，最后是通过微蒸馏的方法纯化Os；利用阴离子交换树脂的方法分离纯化Re。

X-ray analyses indicate that lattice parameters decrease due to Cu-doping; while XPS results show that Cu-doping leads to positive chemical shifts of the Cu 2P1/2 and La 3d5/2 and 3d3/2 levels, implying that Cu-O and La-O bondings are strengthened and their bond lengths are shortened; while magnetization measurements show that after 8 hours' Arannealing, the Neel temperature of Cu-rich sample is about 31K higher than that of the sample without Cu doping, indicating that the three-dimensional antiferromagnetic correlation is enhanced.

结合各种分析手段认为，掺杂的铜原子部分替代了 La 位，也有填补 CuO2面的 Cu 空位和在晶界形成微量第二相的可能占位情况，使得铜的掺杂取得了增强二维特别是三维反铁磁交换作用的效果，促进了La2CuO4+δ系统的相分离。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
