In the process of corrosion in 3.5% NaCl solution, the ceric aluminum brass forms a homogeneous and tight corrosion film on the surface, which can inhibit the diffusion of Zn from the surface of matrix to the solution, and restrain the dezincification to a certain degree.

在NaCl (3.5%)溶液中腐蚀过程中，铈铝黄铜表面形成一层较均匀致密腐蚀产物膜，较好地阻止了Zn从基体表面向介质中扩散，在一定程度上抑制了脱锌；铈铝黄铜耐腐蚀性能略优于砷铝黄铜，腐蚀速率为6.2×10^(-3) mm/a。

It was found that increasing pressure for blank can improve the compactedness of blanks so as to make foam aluminium materials with homogeneous pores. Foaming temperature, as one of the main influencing factors on foaming process, should be controlled higher than the melting point of Al or Alalloy to a certain extant in order to keep a reasonable viscosity. Thus, the foam aluminum with homogeneous pores and high porosity is available. As shown by experiments, such materials should be made on conditions that they shall be protected with molten salt under 300?MPa pressure at 675～680?℃.

研究了粉末冶金法制备泡沫铝材料的方法讨论了发泡过程中的保护方式、制坯压力、发泡温度等参数对泡沫铝体积质量、孔隙率、孔结构的影响，并对发泡机理进行了探讨增大制坯压力使得金属坯致密，可以得到孔结构均匀的泡沫铝材料；发泡温度是影响发泡的主要因素之一，发泡温度控制在高于铝或铝合金熔点，同时保持熔体具有一定粘度的范围内，能够得到孔结构均匀、高孔隙率的泡沫铝材料实验结果表明：采用熔盐保护方式，在300MPa的压力下，温度在675～680℃时，可得到孔径均匀、孔隙率高的泡沫铝材料。

The experiment confirms that the Al2O3/Cu composite material by internal oxidation of deeply aluminized pure copper matrix is a kind of superiority diathermanous copper material as being the metallurgical equipment material.

将纯铜深层渗铝内氧化A12O3/Cu复合材料的性能与纯铜深层渗铝固溶时效合金的性能进行对比，确定纯铜深层渗铝内氧化A12O3/Cu复合材料作为冶金设备用传热铜材料的性能的优越性。

Aluminum liquid refine is the key process of melting the aluminum alloy. The refined can remove hydrogenium, purify aluminum liquid, avoid pinhole point, which will influence on the mechanical and working performances directly.

铝液的精炼处理是铝合金熔炼过程中的关键工序之一，精炼能除氢和除渣，净化铝液，达到消除铸件针孔的目的，并直接影响铝铸件的力学及使用性能。

In upper horizon, aqueous aluminum originated from both organically bound aluminum and inorganically bound aluminum, but organically bound aluminum seemed to be more important.

下层土壤中，铝近乎全部来源于无机键合铝，土壤水 H+浓度成为影响铝释放过程的最主要因素。

The significant changes was found in low and high aluminium exposed groups. Conclusions 1. Chronic aluminum exposure during pregnant and lactational stage can damagethe function of learning and memory of pups.

根据本研究所得的实验结果，可得出以下结论： 1、大鼠孕哺期铝暴露可使其子代鼠血铝、脑铝含量明显增加，并引起学习记忆障碍。

Consequently, studying the effect of aluminium on Long-TermPotentiation and approaching its possible mechanisms can elucidate the mechanisms ofaluminium on study and memory. The research indicated that the pregnant and lactational stage is the importantstage for the filial brain growth and development.

因此本次实验采用整体动物实验的方法，通过对大鼠孕哺期慢性铝暴露，以子代大鼠海马为研究对象，探讨大鼠孕哺期铝暴露后对其子代大鼠海马LTP形成、维持的影响，并从蛋白激酶C表达的途径为阐明铝影响LTP的机制提供思路。
