刚性的

The structural characteristics, such as short bridges, more rigid ligand, larger dihedral angle and different bridging groups, had significant effects on the stability, catalytic activity and polymerization behavior.The polymerizations of cycloolefin were carried out by catalystsβ-diketonate titanium, respectively.

催化剂桥基长度的缩短、两茂环之间的二面角及立体刚性的增大、两桥联基团的结构差异等因素对催化剂的热稳性、聚合活性及共聚情况都有一定的影响。

Block-copolyimide film from pPDA/ODA-PMDA was studied by TEM, SEM, PLM, ultra-deep three-dimensional microscope, TMA, and WAXD, which showed that the extensile strength and modulus of b-PI film were higher than that of irregular copolyimide film. It was also revealed that there was a large amount of crystallite formed in b-PI film, which was mainly attributed to its chain structure: rigid pPDA-PMDA chains were easy to form crystal nucleus because of phase separation, based on which semi-rigid PMDA-ODA molecular chains began to crystallize.

以pPDA／ODA-PMDA型嵌段共聚酰亚胺薄膜为对象，借助TEM、SEM、PLM、超景深三维显微镜、TMA、WAXD等手段，研究结果表明：b-PI薄膜的拉伸强度、弹性模量均高于无规共聚酰亚胺薄膜；b-PI薄膜中形成了大量的微晶，这是由于刚棒状的pPDA-PMDA分子链段因相分离容易形成晶核，然后半刚性的PMDA-ODA分子链段以PMDA-pPDA为晶核进行晶体生长造成的，而且ODA-PMDA分子链的结晶和酰亚胺化反应基本上是同步进行的。

Whereas the high conductive layer in the northern crust is connected with Asian continent′s resistance against the northward underthrust of India plate and the southward underthrusting of Asian continent.

研究区内的冈底斯及羌塘地体的中、下地壳普遍发育高导层，反映了印度大陆碰撞、俯冲过程的效应与痕迹，而高导层之下的高阻块体则可能是向北俯冲、冷的、刚性的印度大陆地壳。

The only thing that remains are inflexible laws of physics, storms of unharnessed energy, and eternal sameness.

差异消失、有序活动终止、柔性不见踪影，唯一还在只有刚性的物理定律、巨大的未被利用的能量以及永恒的单调。

Displayed similar photophysical changes in the presence of DNA. But the complex increased the viscosity of DNA weakly. This suggests that due to the constraint from the rigid structure of the macrocyclic ligand, the complex binds to DNA by weak intercalative interaction.

在光谱方面也出现了类似的现象，但DNA的粘度却略有增加，说明环上的苯环可能由于受到整个配合物结构刚性的限制，只能以较弱的插入方式与DNA作用。

This idealised front/rear weight distribution, together with the frame's strength/rigidity balance and caster and trail dimensions make for a natural handling feeling that perfectly complements the machine's sensual and exciting power characteristics.

这idealised前/后座的重量分布，连同框架的强度/刚性的平衡和连铸机和径尺寸，使一个自然处理的感觉，能够完美地契合机器的感官刺激，功率特性。

For the fourth part, we first designed a hydrogen bonding-mediated rigidified polymer. The X-ray crystal analysis of its fragment molecules showed the existence of consecutive intramolecular hydrogen bonds, which forced the backbone to adopt a rigidified planar conformation.

在第四部分工作中，首先我们设计了一种分子内氢键控制构象的聚合物，通过对其氢键骨架的单晶培养和结构解析证实在它们的结构中存在三中心氢键使得它们采取平面刚性的构象。

In other words, regardless of the economic downturn in the economic cycle or cycles, as a result of a specific consumer target, making the toy market is basically stable, which somewhat similar to the cosmetics market, the relative rigidity of consumer demand, making toys, cosmetics these industries affected by economic cycles have little effect.

也就是说，不管经济处于景气周期还是不景气周期，由于特定的消费对象，使得玩具消费市场基本上是稳定的，这有点类似于化妆品市场，相对刚性的消费需求，使得玩具、化妆品这些产业受经济周期的影响不大。

The copolymers were systematically characterized by elementary analysis, FT-IR, UV-visible spectroscopy, solution high-resolution 〓H-NMR and solid-state high-resolution 〓C-NMR spectroscopes, solubility examination; circular dichroism technique was firstly used to characterize chain structure of the copolymers.

本文通过在刚性的PD聚合物分子链中引入邻乙氧基苯胺链节，使用化学氧化聚合和电化学氧化聚合两类新型聚合方法，合成了三种PD异构体与PHT的共聚物，并进行了聚合反应、结构和性能表征的系统研究，并且比较了氨基的相对取代位置对聚合活性的影响。

Lorca讲的那样,格林纳达跟赛维亚如此不同,一个阴柔,一个刚性.他说:seville is man in the full complexity of his sensuality and emotion. It is political intrigue and the triuphal arch.

真服了那些在一个陌生的国家，好多年都不会说当地语言的外国人，除非他们把自己关在笼子里，才能对周围的一切美丽视而不见，不去想方设法与当地人沟通。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
