Tungsten grain is one material that has high strength and body-centered cubic structure, and it distributes in the matrix that is soft and has the surface-centered cubic structure.

其中钨颗粒是强度较高的相，体心立方结构的钨颗粒均匀的分布于面心立方结构、较软的基体相当中。

After heat treatment at 1100C in air, the elements of the substrate and the bond coat diffuse and the diffusion of Ni is an uphill diffusion. The layer of r " phase and the layer of A12O3 or NiAl2O4 were formed at the interface of the substrate and the bond coat and at the interface of the bond/top coat, respectively. The thickness of the r " phase and the oxide layer increases with the increase of the time of the heat treatment.

经1100℃热处理，基体和底层中元素发生了相互扩散，并在界面析出γ'相，γ'的存在使界面的结合为冶金结合；在底层／面层界面由于底层被氧化和Al与ZrO_2氧化还原反应形成Al_2O_3等氧化物，Y'和氧化物的厚度随热处理时间延长而增加。

本文叙述了国产基茨系列中压变频器在煤炭矿井采煤作业面输送皮带机变频改造中的应用；详细地叙述了输煤皮带机的工作原理和变频改造的方法。

For thin polycrystalline films, especially those with columnar structure, once the diameter of grains on the film surface is larger than the film thickness, the total area of above and under basal planes (film-substrate interface) will be larger than that of side plane. And if the film precipitates on the substrate with thermal expansion coefficient different from that of the film, great thermal stress will be introduced during annealing.

对于薄膜特别是柱状晶薄膜，当晶粒在膜平面内的尺寸大于膜厚时，柱状晶粒的上底面和下底面的面积将大于侧面的面积，如果薄膜还附着在与其热胀系数不同的基体上并在不同于沉积温度的条件下退火时，膜中将存在较大的热应力。

It was found that the homogeneous orientation tendency of azobenzene was a common phenomenon in the self-assembled films fabricated by electrostatic layer-by-layer dipping process of the side-chain azo polyelectrolytes and poly(diallyldimethyl ammonium chloride); substituents that link to azobenzene have influences on the orientation of azobenzene in self-assembled films,which could be attributed to charge interaction and dipolar interaction between the chromophores and the polycation substrates.

研究表明，侧链型偶氮聚电解质自组装膜中偶氮生色团普遍存在一定程度的沿面取向。偶氮生色团所带端基的类型对其在自组装膜中的取向程度有较大的影响，这主要取决于偶氮生色团与聚阳离子基底的电荷相互作用和极性相互作用等。
