铝的

Here is a hefty heap of scrap aluminum that was given to me.

We have found that there are regularity changes in the Raman spectra of grossular-andradite as the rise of iron in the crystal structure from grossular to andradite after studying of Raman spectra of grossular-andradite, that is to say, their peaks shift to low wavenumber; At the same time , there are some changes in the bond angles of O-Si-O and O-Y-O:the higher of iron contents, the evidenter of splitting of two wind vibration peaks of SiO4 tetrahedron and YO6 octahedron.

通过对钙铝榴石-钙铁榴石的拉曼光谱研究发现，从钙铝榴石到钙铁榴石，随着矿物结构中铁的含量的增加，他们的拉曼光发生规律性的变化，即所有的峰向低波数方向发生漂移；同时，由于铁含量的不同使得石榴石晶体结构中O-Si-O与O-Y-O之间的键角发生了一定的变化，在其拉曼光谱谱图上表现为铁的含量越高，[SiO4]四面体和Y-O八面体的两个弯曲振动峰分裂得越明显。

This gold aluminum cover was designed to protect the Voyager 1 and 2 "Sounds of Earth" gold-plated records from micrometeorite bombardment, but also serves a double purpose in providing the finder a key to playing the record.

设计这个金色的铝盘的目的是保护星际旅行者1号和2号上面被称作&地球之声&的记录，是镀金的，其中也有描绘小陨石轰击地球形成的印记；但铝盘还有另一个用途就是，可为该记录的发现者提供播放其中信息的钥匙。

The effects of magnetic seed, aluminum sulphate and pH value on phosphorus adsorption, precipitation and coagulation were surveyed. The results made it clear that Al ion as precipitant and coagulant was the main effect factor on P removal; as adsorbent magnetic seed had little effect on P removal, but made the phosphate precipitate sink faster; pH value had effect on both precipitation and adsorption.

研究了磁种、硫酸铝、pH值等对磷的吸附、沉淀、凝聚的影响，结果表明：铝离子的沉淀作用是除磷的主要原因；磁种的吸附作用对除磷的贡献较小，但使磷酸盐沉淀物的沉降性能大大提高；pH值既影响沉淀作用，也影响吸附作用。

The results reveal that spectra obtained by different parametric methods are similar. The spectra of normal cells' voltage have only one noticeable lobe due to fluctuation of molten alumina at anodes, while spectra of other abnormal cells have one mainlobe and one sidelobe. In cells with carbon in bath the spectral mainlobe of cell voltage is still due to the fluctuation of molten alumina at anodes and the sidelobe is due to the fluctuation of carbon in bath; in cells with metal pad wave, the spectral mainlobe is due to metal pad waving and the sidelobe is still due to the fluctuation of molten alumina at anodes. Compared with wavelet packet analysis, spectral analysis is simpler and takes less time in calculation, which is a big merit in the large-scale application of online diagnosis systems of working conditions in aluminum reduction cells.

研究结果表明：不同的参数估计法得到趋于一致的频谱分析结果，正常槽只有1个尖锐谱峰，对应于阳极下熔融氧化铝涌动的特征峰，其他故障槽都有2个特征谱峰，即1个主峰和1个次峰，碳渣槽的主峰仍然对应着阳极下熔融氧化铝涌动特征峰，次峰对应悬浮碳渣的涌动特征峰；铝液波动槽主峰对应铝液波动特征峰，次峰对应着熔融氧化铝涌动的特征峰；频谱分析相对于小波包分析具有算法简单、耗时少、物理意义明确等特点，在槽况在线诊断系统的大规模推广中具有优势。

In this project, the selection criteria of matrix and reinforcement for obtaining composites with high strength and toughness are determined. The as-cast and aged microstructures of composites reinforced with particles of different strength are observed, and their metallurgical conditions and stabilization mechanisms are analyzed. The aging precipitation behaviors and mechanisms are studied. Some characteristics of nano-materials (micro-distortion areas) are found in 150nm- Al2O3p/Al composites and their formation mechanisms are expatiated. The "flexible" restriction to the deformation of the matrix by low strength AlN particle is observed by in-situ TEM and SEM techniques, and the mechanisms of its resist on cracks propagation and its contribution to composite strength are revealed. The high temperature deformation behaviors of Al2O3p/Al composites are studied. A rare-earth coating is established on sub-micron Al2O3 particles, leading to an improvement in wettability between coated Al2O3 and liquid aluminum and a decrease in infiltration pressure. The strength and ductility of coated particles reinforced composite are also increased. The interfacial characteristics, bonding structures and their formation mechanisms are studied, and the crystal orientation relationships between reinforcement particles and aluminum matrix are investigated. Finally a lighter composite with better balance of strength and damping properties is reinforced with hollow ceramic microballoons of ultra-lower strength.
