在这个体系中,我们找到了甘氨酸和水作用的四种稳定构型,其中最稳定的构型是一个环状的双氢键结构。
Four reasonable geometries on the potential energy hypersurface of glycine and water system are considered with the global minimum being a cyclic double-hydrogen bonded structure.
说明蒙脱石和改性蒙脱石对AFB_1存在化学吸附,其选择性吸附机制可能主要是由于它们边缘的羟基与AFB_1之间形成了双氢键。
The main chemical mechanism of the adsorption was the formation of double hydrogen bands between AFB_1 and montmorillonite or modified montmorillonite.
阻尼和外电场的作用使得带有非对称双阱势的氢键链存在扭结孤子激发。
The damping force and the external electric field caused the kink soliton excitation in a hydrogen bonded chain with asymmetric double well potentials.
That tells you something about the physical chemistry of the molecule; that it's these hydrogen bonds that hold the double strands and I can break those down under certain conditions.
我们从中可以知道一些,DNA分子的理化特点,双链是由氢键连接在一起,在一定条件下这些氢键可以断裂
That's because you have to satisfy this base pair matching in order to have hydrogen bonding in each of the struts of the ladder in order to form a stable structure.
NA双链要满足互补配对原则,以使碱基对之间,形成氢键,从而形成稳定的双链结构
If I had a beaker sitting on the table here and it contained a million blue double stranded DNA molecules and a million red double stranded DNA molecules and I heated it up and added a little base, I'd soon have four million individual strands just floating around in the solution because I've broken up this hydrogen bonding and the DNA molecules fall apart.
假如我这里有一个烧杯 里面,盛有一百万条蓝色DNA双链和,一百万条红色DNA双链,然后我稍微加热一下烧杯,并且加一些碱,很快我就有了四百万条DNA单链,漂浮在溶液里,因为我已经使得氢键断裂,DNA双链也随之打开
