The results of Monte Carlo simulation disclose that in large range of nitrogen fugacity the solubility of the interstitial nitrogen in αFe obeys Sievert's law. This range is much larger than that in γFe-N system. The results also show that in order to get the same level of interstitial nitrogen solubility in αFe-N system during solid state nitride, larger nitrogen fugacity is needed at the lower temperature.

该逸度范围比面心立方结构的Fe-N体系中大得多；由模拟计算结果还可知，在固体渗氮过程中，若要使合金含有同样浓度的固溶氮，渗氮温度较低时应保持较高的氮分压。

A new kind of magnesium alloys has been synthesized by high energy ball-milling of Mg and Fe mixed powders.Due to the high corrosion speed and reacting efficiency,the alloys are generally called super-corroding alloys.A SCA bulk is fabricated through cold-pressing and sintering the mechanically alloyed Mg-Fe powders.The chemical reaction of SCA with seawater rapidly releases heat and hydrogen gas,which may play very important roles in many ocean applications.For example,the reaction heat can be used to keep diver clothes warm;SCA corrosive links with the function of self-destruction can be utilized to control the sinking and floating of sonobuoy, and to salvage the training torpedo or other instruments.In addition,the reaction heat of SCA can be applied to heat food,machinery and ice or snow,which is thus very helpful for mountaineers.

超腐蚀合金采用Mg和Fe混合粉末，经高能球磨机械合金化、冷压、烧结，形成Mg-Fe合金块体，具有很高的海水腐蚀速率和反应效率，该合金化学反应放出的热量和氢气可在海洋工程中发挥重要作用，例如：可为深海作业潜水衣的保暖提供热量；由其制造的腐蚀链通过自毁机制，可用来控制声纳浮标的沉浮时间，打捞和回收水中的贵重仪器、装置以及训练用的靶雷；在偏远地区和寒冷地带，利用该合金的反应放热特性，不仅可加热机械、仪表或食品，而且能为登山运动员提供取暖所需的热量。

The nature of the acceleration unit-impulse response function of unbounded medium tending to vary linearly is proved by means of asymptotic analysis. Thus, the acceleration unit-impulse response function can be regarded as the summation of a linear function and a residual part which converges to zero. Based on this decomposition, two FE-SBFE coupling procedures are presented based on system realization and truncation integral technique respectively.

本文系统研究了相互作用力-运动关系的位移表达、速度表达和加速度表达，通过比较位移、速度和加速度单位脉冲响应函数的SBFE求解过程，确定采用相互作用力的加速度表达；通过渐近分析证明了无限地基加速度单位脉冲响应函数具有随时间延长而趋于线性变化的性质；利用这一性质将加速度单位脉冲响应函数分解为一个线性函数和一个衰减到零的残余函数的和，以此为起点发展出两种FE-SBFE时域耦合方法：基于系统实现的FE-SBFE时域耦合方法和基于截断卷积的FE-SBFE时域耦合方法。

It is the fluorosilicic ion that exsits in the slurry and plays an important role in flotation, fluorosilicic ion not only reacted with Fe〓 on the surface of aegirine to form ionic compound, but also formed stable Si-F bond in Si-O etching reaction. Only ionic compound was obtained when it was attached to hematite surface according to the theories of coordination chemistry, Compared with SiF〓, Fatty acid ion preferentially acts with Fe〓 on the minerals surface, therefore, SiF〓 Can't obstruct the adsorption of collector on the surface of hematite completly, but can reduce the flotation recovery of aegirine selectively.

运用FTIR、XPS等测试方法仔细研究了氟硅酸盐抑制剂对含铁硅酸盐钠辉石的选择性抑制作用机理，氟硅酸盐在弱酸性条件下对赤铁矿浮选的抑制作用很微弱，而对含铁硅酸盐钠辉石强烈抑制，从而扩大了两者之间的浮选差异；SiF〓是矿浆中起抑制作用的主要成分，SiF〓不仅与钠辉石表面的Fe〓形成离子型配合物，而且还与Si-O键形成稳定的Si-F共价键，而与赤铁矿表面只能形成离子型配合物，根据晶体配位场理论，与SiF〓相比较羧酸根离子将优先与矿物表面Fe〓发生配位作用，因此SiF〓的存在并不能完全阻碍捕收剂在赤铁矿表面的吸附作用，却能够选择性地抑制钠辉石的上浮。

The deposition speed of Fe powder was mainly influenced by current ,initial catholyte pH and mol-ratio of Fe and EDTA.
