The degree of twist distortion increases with pretilt angle.

同一种液晶分子在取向层的预倾角不同，在力场作用下扭曲变形的程度亦不同，预倾角较大可获得较大的扭曲角；对于不同的向列液晶，弹性常数较小的液晶可在较短的时间产生较大的扭曲变形

In this thesis, we solve this problem by combining the overall functions of potential interactions, which include the van der Waals attractive potential, repulsive electrical double layer potential, Born repulsive potential and magnetic interaction, as well as the hydrodynamic interaction, the gravity and the Brown diffusion, and therefore unveil the significant influence of the interparticle potential on the sedimentation of stable colloidal systems.

在本论文中，通过综合考虑胶体粒子间的势力相互作用——包括vander Waals分子引力势、双电荷层静电斥力势、Born排斥势和磁力势等，还有流体动力相互作用、重力相互作用、布朗热动力等诸多因素的影响，我们解决了这一难题，揭示了粒子间势给胶体系统的沉降行为带来的重大影响。

DEMS combined with the dual thin layer flow through cell is a good tool for the quantitative study on the oxidation of small organic molecules.

微分电化学质谱仪与双薄层流动电解池结合是一个很好的定量研究小分子有机物氧化的有力工具。

We purified the target protein under natural conditions by MCAC through Ni-NTA resin. The purity of this fusion PH domain of IRS-1 was up to 98％. We paned out the oligopeptides that can bind to this target protein from a phage displayed random duodecimal peptide library. The identities of peptide sequences of positive clones were analyzed.

因此，我们利用融合表达载体pRSET在T7启动子的调控下表达出氨基端带六个连续组氨酸标签的IRS-1的PH结构域，利用Ni-NTA介质在非变性条件下对目的蛋白进行了金属螯合亲和层析纯化，获得了纯度达98％以上的PH结构域融和蛋白，以此为靶分子，从噬菌体展示随机12肽库中筛选出能够与其相结合的短肽，并分析了阳性克隆的序列一致性。

This paper analyzes shell electron pair repulsion theory, valence-bond theory and molecular orbital theory on molecular structure of noble gas compounds.

They also indicate that the in itro system using mouse ES cells mimics in io deelopment and should proe useful in the study of molecular mechanisms for endoderm and gut deelopment.

这些结果也显示了利用小鼠胚胎干细胞的体外系统模拟了体内的发育过程，而且对研究内胚层和肠道发育的分子机制是很有用的。

To determine whether the same molecular mechanisms are inoled in the formation process, the expression pattern of transcription factors regulating endoderm and gut deelopment in the mouse embryo was examined by in situ hybridization and compared with in io expression.

为了证明在成形过程中是否也具有相似的分子机制，我们通过原位杂交同体内表达比对的方法来检查小鼠胚胎中调节内胚层和肠道发育的转录因子的表达模式。

ESCs are traditionally regarded as ICM cells, though some scholars believe they are more closely resemble cells from the epiblast. But recent evidence about cell molecular markers indicate that ES cell's characteristics resemble early germ cells.

传统观念常常把ESCs等同于ICM细胞，也有学者认为ESCs更象上胚层细胞，而在已知的分子标记基因方面，ESCs所具有的特征更接近体内早期生殖细胞。

Such that ,how to utilize normal dyeing and finishing equipment and detect dyeing and finishing processes of Tencel fabric for local enterprise is very urgent for dyeing and finishing industry of Henan Province.Tencel fiber molecule crack easily to form fibrilla for its special spinning process . In this way, the surface of Tencel fabric will appear a layer of fine staple by the function of wet and mechanical friction.

由于Tencel纤维的特殊纺丝制造工艺，其纤维素分子容易裂开而形成原纤，进而在湿态及机械摩擦作用下，织物表面就会浮出一层极细的短纤毛，其状如"霜白"。

Then, cellular PP films were modified by extraction, oxidation and fluorination in a hydrofluoric acid solution.

红外分析和断面的X射线能谱分析表明，经过相继的化学处理(表面小分子萃取、氧化处理和氢氟酸处理)后，PP孔洞薄膜生成了具有一定(来源：A59BCc747论文网www.abclunwen.com)深度的氟化层。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
