查询词典 grains

The influence of sintering temperature and composition on the microstructure of Y-Ba-Cu-O superconducting ceramic prepared by reactive sintering was investigated. While the oxide powders react and sinter into the superconductor, transient liquid phase can disappear rapidly, and equilibrious liquid phase can promote the anisotropic growth of superconducting grains and isolate the grains.

The results show that the effectiveness of Route A is better than Route B. After ARB of 7 passes, the microstructure of the specimen by Route A consists of thin elongated fibriform grains with an average size of 470 nm, but that by Route B does compressed grains with an average size of 680 nm. The improvement in tensile strength by Route A is greater than that by Route B. The strengthening mechanism of 1060 commercially pure aluminum by ARB is fine-grain strengthening.

The sand dunes analyses data have shown they mainly consist of well sorted, symmetry skewness and find sands, and the kurtosis peak is narrow or very narrow. There are abundant impacts of mechanic process on the surface of quartz grains. The traces of eolian process often superpose on the traces stamped by river and beach processes. The dish--shaped concavities and mechanic pits are the most common surface textures, but the barchan concavities and curved grain edges are indicated the marks by eolian environment. The heavy minerals assemblages of coastal dunes are dominated by relatively high specific gravity which have stable chemical properity suggesting the mordern high dynamic environments of coast area. The depositional structures of coastal dunes are typified by corss--bed sets composed of steep foreset laminates and gentle windward dipping sets. It also contains some shell fragments and strong worn foraminiferal tests that are impossibly found in inland desert. On the other hand, the sandy deposits of the continental shelf of East China Sea are with wide range of grains, and the depositional pattens are quite complicated.

海岸沙丘是晚全新世以来相对稳定的海平面背景下的海岸带风成堆积，其沉积特征是以细沙为主，分选好，搬运方式以跃移占绝对优势，偏度上近对称，峰态窄到很窄；石英颗粒表面机械作用形态丰富，风成作用形态叠加于河流和海滩过程形态之上，碟形坑和撞击麻点是最为常见的表面形态，而新月形坑和曲脊是其指示性的特征标志；沙丘沙重矿物以化学性质稳定、比重较大的种类为主，反映了海岸带目前的高能动力环境；海岸沙丘沙的沉积构造以高角度前积层和低角度顶积层组成的交错层理为典型特征，同时还含有少量内陆沙漠所没有的少量贝壳碎屑和强烈磨损的有孔虫壳体。
