螺旋沟

Depending on a reliable directional field, it can immediately extract some important features such as the center of whorl, ridge and furrow on fingerprint.

依据可靠、误差较小的方向场可以准确快速地找到诸如指纹螺旋中心等特徵，并且使快速提取指纹图中沟和脊的特徵成为可能。

Different to previous complex,〓 tends to intercalate from major groove with partly enantioselectivity.

同以前各种配合物的识别情况不同，〓更倾向与从大沟插入到DNA螺旋中，识别过程呈现出部分手性选择性。

Comparison of SRY/Sry primary structure of human and bovine, the HMG-box was the singular conserved part, but they were similar in the three-dimensional structure.

比较牛和人SRY蛋白结构，仅在保守区HMG-box处有较高的相似性，但是空间构象却比较相似，都是通过结合DNA螺旋小沟来识别7个碱基的核心靶序列，作用方式也很相似，说明虽然SRY/Sry蛋白在物种间序列差异较大，但蛋白的结构和作用方式却是很保守的。8。

Its work principle and structure are presented. Design calculation of the vertical auger attachment, related key technologies and trenching performance of the basic machine are expatiated.

对其工作原理和结构加以介绍，阐述了"变导程"立式螺旋工作装置的设计计算、相应的关键技术和整机的挖沟工作性能。

The results demonstrate that ACM-A is capable of intercalating between the base pairs of DNA double helix, the π-π electronic overlapping between π-electron of ACM-A and DNA stabilizes the ACM-DNA adduct, and through electrostatic interaction, the trisaccharide interacts with the minor groove of DNA owing to C(3') amino group.

实验结果表明，ACM-A主要以其蒽环平面嵌入DNA双螺旋碱基对之间，发生-等电子间相互共轭，同时药物糖基上C3'位的-N(CH3)2基团带正电荷，易与带负电荷的磷酸骨架产生静电吸引，从而发生沟槽作用，嵌入DNA的小沟区，这是二者之间的主要结合模式。并且，DNA与ACM-A药物原型的亲和力要强于还原后的药物代谢产物。
