These growth units were absorbed and join the crystal lattice on the growth interface through collision and aggregation.The powders with better crystallinity and double cone or tetrahedron shape were obtained after amorphous ZnS was treated by solventthermal method.

采用溶剂热处理高浓度条件下制备的ZnS无定形粉末，得到晶态结构完整，形状为双锥状或四面体状的粉末。

The intensity of red emission was far higher than that of the green emission due to the cross-relaxation process ~4F_(7/2+~4I_(11/2)→~4F_(9/2)+~4F_(9/2), which restrained the electron population of green emission energy level, enhanced the efficiency of red light emission remarkably, and brought about high fluorescent branding ratio of red to green.

结果表明：这三种方法得到的样品的形貌分别为无定形、球状和长柱状；同固相法合成的样品的发光性质不同，这三种方法合成的样品的发射谱均为绿光发射主导上转换光谱。

The corium is under the epidermis, it's made up of connective tissue that contains collagenous fiber, elastic fiber, reticular fiber and ground substance between fasciculus, it's very important for the elasticity and lusty of the skin, malnutrition, ageing and long-time excessive exposure to the sun would all lead to wrinkles and sagging of the skin, the reason of this is denature or fracture of collagenous fiber and elastic fiber.

真皮在表皮之下，由胶原纤维、弹力纤维和网状纤维组成的结缔组织，与纤维束间的无定形基质构成，对皮肤的弹性光泽和弹力等有着重要作用，营养不良、衰老或长期过度日晒会使皮肤发生皱纹、弹性松弛，是胶原纤维及弹力纤维变性或断裂的结果。

XRD, EDS and TEM investigation disclosed that amorphous ferric oxide was uniformly dispersed on the surface of carbon black.

XRD、EDS、和TEM分析证明，铁/炭黑复合材料中无定形氧化铁在炭黑表面的含量可达40%，且分散均匀。

Floccule watched on the mineral surface in the analysis of SEM is live embodiment of amorphous substance.

在扫描电镜分析中矿物表面出现的絮状物是无定形化物质的形象表现。

However, POM/PEO interfibrillar segregation and the interspherilute segregation crystalline structures seem unfavourable for the toughness of the blends.5. PEO can improve the friction and wear properties of POM/PEO blends because PEO in the blend melts during friction and transfers to the friction surface, forming a lubricative layer.

磨痕宽度则先减小后增加，这是因为随PEO含量增加，其结晶结构发生了变化，无定形PEO与POM微纤晶穿插有利于减小磨痕宽度。6。

A new method of preparing intercalated and amorphous kaolinite with sodium methoxide was introduced in this article.

利用甲醇钠强烈的夺氢作用，介绍了一种制备插层和无定形高岭土的方法。

Most importantly, with analyzing the calcined cinder by X-ray powder diffraction and scanning electron microscope, it was clear that at an appropriate calcination temperature, the activated SiO2 and Al2O3 in alkaline coal-cinder would react with the decomposed fused Na2CO3 to form a new neutral matter nepheline（NaAlSiO4）and other amorphous silicate compounds,causing an obvious reduction of the alkali content in coal-cinder.

采用X射线粉晶衍射及扫描电镜对煅烧后的灰渣进行表征，揭示了含碱灰渣煅烧脱碱过程的实质，即在适宜煅烧温度下，含碱灰渣中被活化的主要矿物质SiO2、Al2O3和熔融并分解的Na2CO3（分解为修饰网络氧化物Na2O）等发生化学反应转变为中性物质霞石（NaAlSiO4）及其他无定形复合硅酸盐，从而降低了灰渣中的碱含量。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
