The calculated results show that azido in azides has linear structure , the most optimized CaN6 has linear structure , and the most optimized (CaN6)n (n=2～5) clusters have chain structure of perpendicularity of approximate diamond composed by two azido with two Ca atoms . The middle N atoms of azido show positive, the N atoms at both ends of azido show negative, and the N atoms effected with Ca atoms directly show more negative . There is strong ionic bond between the Ca and N atoms. The IR spectra of the most optimized (CaN6)n (n=1～5) clusters have four vibrational sections , the whole strongest vibrational peak lies in 2195～2280cm-1,and the vibrational mode is anti-symmetric stretching vibration of N-N bonds in azido . Stability analysis show that (CaN6)3 and (CaN6)5 clusters are more stable than other clusters .

结果表明，叠氮化合物中叠氮基以直线型存在，CaN6团簇的最稳定结构为线型结构，(CaN6)n(n=2～5)团簇首先由两个叠氮基与两个Ca原子构成一个近似菱形，再由菱形相互垂直形成链状最稳定结构；叠氮基中间的N原子显示正电性，两端的N原子显示负电性，且与Ca直接作用的N原子负电性更强，金属Ca原子和N原子之间形成很强的离子键；(CaN6)n(n=1～5)团簇最稳定结构的IR光谱分为4个部分，其最强振动峰均位于2195～2280cm-1，振动模式为叠氮基中N-N键的反对称伸缩振动；稳定性分析显示，(CaN6)3和(CaN6)5团簇相对于其他团簇较为稳定。

通过模拟分析比较，揭示出了环件轧制过程中的金属流动规律：轧制时，环件外侧的变形最大，厚向中心部位变形最小，内侧的变形程度介于中间；环件内外环面的压应力分布和变化规律：在垂直于环件轴线的对称面上，压应力分布近似对称状态，而且在对称面上的应力最大，往端面方向开始减小；指出了环件轧制中轧辊与环件摩擦对环件成形的影响：对于环件的宽展变形，摩擦的影响很小，可以忽略；分析了环件进给速度对环件成形的影响并阐述了环件厚向中心部位凹陷产生的原因，提出防止凹陷的措施：在轧制时，尽量使用快的进给速度有利于防止端面凹陷的产生；研究了导向辊位置对环件成形以及轧辊受力的影响：导向辊的位置对环件的宽展变形影响很小，但对轧辊的受力影响较大，当导向辊的中心位置位于毛坯初始中心位置之上时，驱动辊和芯辊的受力相对较小，这是导向辊导向时优先考虑的位置。

Brief probe hybridized with long target DNA, the hybridization position had no effects on the binding amount, but mid-position of hybridization would prolong the hybridization time, which was due to the steric hindrance on the surface.

结合位点不同对杂交量无明显影响，但由于晶体表面DNA空间结构的影响，结合位点位于靶序列中间时杂交时间明显延长。

The results of its fluorescence probe showed that when the guanidine hydrochloride concentration in denaturation solution was about 1.0 mol/L,there existed some stable hydrophobic regions,which could interact with a hydrophobic reagent 8-anilino-1-naphthalene sulfonic acid,in the partially folded intermediate of Bacillus amyloliquefaciensα-amylase;with the denaturation concentration increasing,the stable hydrophobic regions disappered.the results of fluorescence quenching using acrylamide and potassium iodide as quenchers showed that using acrylamide as quenchers,with the protein denaturation extent increasing,the number of Trp that can be quenched increased untill all the Trp residues were quenched;Using potassium iodide as quenchers,with the maximum number(8) of tryptophan residues in a partially folded intermediate Bacillus amyloliquefaciensα-amylase molecule could be quenched by potassium iodide;with the denaturation concentration increasing,the number of Trp that can be quenched decreased to 5.the results of their protein electrophoreses and SEC showed that no aggregate or aggregate precipitation of Bacillus amyloliquefaciensα-amylase formed during the whole unfolding/refolding procedure of Bacillus amyloliquefaciensα-amylase induced by guanidine hydrochloride or urea.

ANS外源荧光探针结果表明：盐酸胍诱导的芽孢杆菌α-淀粉酶分子去折叠过程中存在着能够与探针分子1-苯胺基-8-萘磺酸结合的稳定的疏水区域；而随着芽孢杆菌α-淀粉酶分子在盐酸胍溶液中变性程度的加深，这一疏水区域逐步被瓦解。丙烯酰胺和碘化钾猝灭结果表明：在盐酸胍溶液中，随着芽孢杆菌α-淀粉酶分子变性程度的进一步加深，其分子内能够被丙烯酰胺接近的色氨酸残基逐渐增多，直至全部被猝灭。但位于芽孢杆菌α-淀粉酶分子表面的能够被碘化钾猝灭的色氨酸残基，在中间态芽孢杆菌α-淀粉酶分子中数目达到最大的8个，而随着其分子变性程度的进一步加深，反而减少至5个。

Well, the restaurant was called the Board Room. Now, the Board Room back then was a restaurant on Vermont Avenue in Washington, D.C., and it was a strip club. In fact, it was famous because the young women who worked there would wear these completely see-through baby doll negligees, and they would dance on top of the tables while the patrons ate lunch.
