骨架

This is because heteroatom species have been fixed in the framework of the zeolite primary units when the seed solution is prepared and with the self-assembly of the zeolite primary units surrounding the surfactant, heteroatom species are directly introduced into the mesostructure.

这是因为在制备沸石导向剂的过程中，杂原子被固定在沸石的微结构单元中，当沸石导向剂与表面活性剂通过自组装过程形成介孔分子筛时，杂原子随沸石的微结构单元一起进入了产物的骨架当中。

When the mesostructure is basically formed, the pH value of the reaction system is adjusted to 7-8 and then the hydrothermal crystallization is prolonged for some time to obtain heteroatom-incorporated mesoporous silica. The aim of adjusting pH value to near neutral is to change heteroatom species from the cationic to oxo form and therefore can enter the mesoframework through condensation with silanol groups in the wall.

该方法主要的特点是：操作简单（以调节体系pH值代替繁琐的后处理过程），效率高（可以得到Si/Al=5且铝物种全部处于四配位的骨架位置的Al-SBA-15），不破坏产物有序结构（产品具有高度有序的介孔结构），具有普遍性（适用于多种杂原子的掺杂如铝、钛、钒）。

For example, we have conducted the sequence screening on the binding sites of the interface of Barnase/Barstar complex and found that our DGA method can not only determine which position is more conservative and more important, but also redesign the binding sites rationally. The random sequence design for α,β,α/β and α+β four folding motifs have also been practiced and revealed that there are both homology evolution and heterology evolution of protein sequences compatible the same backbone motif.

例如，通过对典型的Barnase／Barstar复合物界面研究发现，它可以确定界面结合位点的重要性和保守性，并对结合位点进行合理的序列重新设计；通过对α、β、α/β、α+β等四种折叠模式骨架的随机序列设计，发现在蛋白质进化过程中，对同一种结构模式同时存在序列的同源进化和非同源进化这两种趋势。

Homogeneous Markov chain ; embedding problem ; bistochastic matrix ; discrete skeleton

齐次马氏链；嵌入问题；双随机矩阵；离散骨架

These peculiar features may have developed as functional convergence to locomotory features of monotremes, or the presence of lumbar ribs in this newly discovered mammal and their absence in its close relatives might be due to evolutionary developmental homoplasy.

该动物的部分骨架很不像兽亚纲哺乳动物：从胸椎往下到脚踝，该哺乳动物都非常像鸭嘴兽，这也许是功能交汇的结果。

The city planning the "big" font highway network and the "three vertical and nine六横line" gradually formed the main framework of the road, in order to build a "1 hour economic circle" laid the foundation.

该市规划的"大"字型高速公路网及"三纵六横九条线"的公路主骨架逐步形成，为构建"1小时经济圈"奠定了基础。

"The doctor of the future will give no medicine, but instead will interest his patients in the care of human frame, in diet and in the cause and prevention of disease."

"未来的医师给予病人的，将不会是药物，而是致力於保养人类的骨架，饮食控制及找出造成疾病的原因，並预防之。"

An additional consequence of the polyamide backbone is that PNAs hybridize virtually independently of the salt concentration.

关于聚酰胺骨架的另一个推论是： PNA的杂交与溶液盐溶度无关。

Before starting work on the bones, I studied some pictures of whale skeletons to give me a basic idea of the type of iconography I need.

在绘制骨架之前，我研究了一些鲸鱼骨骼图片，这样我就对所需的图像类型有了一个基本概念。

This indicated that the electronic structure of the heme is effected by the imidazole binding.

表明这些区域的肽链骨架位置及氢键网在咪唑配位后已发生改变。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
