结晶

The usually used electron-transporting materials have disadvantages.They can be easily formed crystal,have lower electron affinity,a narrow gap and difficult to limit the complex exciton to the luminescence layer,all of these disadvantages limit,their application.

有机电致发光材料中常用的电子传输材料容易结晶和低的电子亲和性限制了它的应用；并且能隙较窄，难以将复合激子限制在发光层。

However, the properties of biomacromolecule are different from inorganic and organic compound with smaller molecular weights, which include electrostatics property, more complicated shape, the instability of physical and chemical properties and so on. These make crystallization process of biomacromolecule more complex.

然而，生物大分子的许多特性不同于有机和无机的小分子，例如：静电学性质、较复杂的形状及物理化学不稳定性等等，这就使生物大分子的结晶过程变得较为复杂。

Another point is that the void ellipticity as a shape parameter is contained in this constitutive equation to consider both the void extension and closing.

其中晶粒度的演化方程是根据动态再结晶和晶粒长大两个物理过程的微观机理建立起相应的细观模型，给出自由能表达式后确定的。

It was an emanation of her spirit, a pure and gracious crystallization of her divine essence

她的身子不但是她精神的外衣，而且是她精神的光彩，是她神圣的精华的纯净温婉的结晶。

Her body was more than the garb of her spirit. It was an emanation of her spirit, a pure and gracious crystallization of her divine essence.

她的身子不但是她精神的外衣，而且是她精神的光彩，是她神圣的精华的纯净温婉的结晶。

Permeable durability reinforcing agent used for concrete surface is a material sealing surface of concrete, and it can permeate into inner of concrete and fill or block the pores of concrete surface with dry crystal or emulsoid generated by reaction between it and chemical compound in concrete. It is important for the protection of concrete structure.

混凝土表面用渗透型耐久性增强剂是一种针对混凝土表面的渗透封闭型材料，其可渗入混凝土内部，并通过干燥结晶或与混凝土内部相关物质反应生成乳胶体将混凝土表层的孔隙填充、堵塞，对已有混凝土结构的防护具有重要意义。

The disadvantages are mainly high equipment costs and plugging of the lines by sediment , salt encrustation , or algae .

缺点主要是设备费用高，管道易被泥沙，盐分结晶或藻类植物堵塞。

Malfunction of the metallic stent can be caused by encrustation of crystals, bacterial sludge, bile salts, and tumor compression or tumor ingrowth.

金属支架的功能障碍可以由胆管内的结晶凝块，细菌性污泥，胆盐，及肿瘤压迫或肿瘤直接侵入支架。

On the other hand, with low process temperature and high Ar flow, the structure is amorphous due to significant energetic particle impingement and less diffusion energy by substrate heating. Phase transformation through process heating and post heat treatment were also discussed.

特别的是，利用高温镀膜制程(550~600aC)及低Ar气体流率(10~15 s.c.c.m)之制程控制，可使结构形成结晶状态，相反地，若使用低温镀膜制程(500~550aC)及高Ar气体流率(15~20 s.c.c.m)之参数控制，则使结构偏向非晶质化。

It can decrease the surface free energy barrier toward nucleation and accelerate the crystallization rate of PEN at high temperature.

在高温下，SB与PEN发生化学反应，生成可以起到成核作用的物质，降低了PEN的成核表面自由能位垒，提高了PEN在高温区的结晶速率。

Fancy gold-plated dangling earrings with facetted White Opal crystals.
