镁

The main raw material for producing magnesium carbonate and magnesium are magnesite, dolomite and bitten, which have abundant reserves in our country, especially the reserves of magnesite and dolomite, that not only holds the domain position but also has superior quality in the world, which establish the massy material developing foundation of magnesium industry.

但我们也应该看到虽然我国具有发展镁盐产品的优越条件，但因目前绝大部分现有生产厂家均属乡镇企业，资金有限，生产规模小，设备陈旧，技术力量薄弱，提高产量及质量的能力受到限制，且生产的品种单一，使我国镁盐的生产仍处于粗制初级、原料性产品的阶段，远不能满足国民经济发展的需要，高档、功能化产品仍需从国外进口，出口产品的价格只有进口产品价格的几分之一。

钼酸钠的加入减弱了腐蚀性Cl-在试样/介质界面的吸附，同时参与镁合金试样在模拟冷却水中表面膜的生成，使表面膜变得致密，从而较好地抑制镁合金的腐蚀；其缓蚀作用属于阳极抑制型缓蚀作用。

The grain boundary effect decreased monotonously with the increase of Mg doping in the range of testing temperature.

在研究温度范围内La_0.8Sr_0.2Ga1-yMgyO_3的晶界效应随镁含量的增加而降低，从而随镁含量的变化而表现出不同的离子传输机制。

The composi-tion of the seawater has changed rapidly since Phanerozoic, and the prolonged mineralogical changes of marine non-skeletal limestone and potash evaporates occurred in a phase on a 100-200 Ma.

结果表明：显生宙以来海水组分发生变化，经海相非骨骼灰岩和钾盐蒸发岩矿物学研究，发现这两种沉积岩长期以来连续变化，在"文石海"是MgSO4型蒸发盐，在"方解石海"是KCl型蒸发盐，从白垩纪晚期、第三纪早期的底部石盐溴含量及矿物学特征表明，此时处于"方解石海"，古海水组分的特点是造成缺硫酸盐型钾盐矿床形成的物化基础；通过NaCl-KCl-MgCl2-H2O和NaCl-KCl-MgCl2-CaCl2-H2O两个体系相图的分析认为，当时所形成的成钾原始体系母液是高镁、低钾氯化物型的卤水，在母液蒸发过程中，由于原始海侵母液与残余高镁母液的掺杂作用，致使结晶路线直接从氯化钠区到E点母液或光卤石与氯化钠共饱线上，而没有通过氯化钠和氯化钾的共饱线，因而在矿体中氯化钾相很少或几乎不存在，由于外界CaCl2型水体的掺杂，使成钾母液进入光卤石相区，随着蒸发的进行，最终形成溢晶石矿物。

First, a series of numerical analysis experiments are designed to investigate the effect of process variables on the damage factor, which constructs the learning samples for training the artificial neural network.
