Sodium amalgam was synthesized according to the method developed by Shanghai Silicate Research Institute, Academy of Sciences of China, by mixing high purity sodium electrolytically purified from industrial grade sodium at 350℃ with amalgam and using ceramic material containing a small amount of Na_2O as separating film.

作者采用中科院上海硅酸盐研究所研究成功的钠汞齐制造工艺，以含少量Na_2O的陶瓷材料为隔膜，在350℃下电解工业级金属钠制成高纯钠，再合成出钠汞齐。

The experiment results show that enstatite is transformed into the perovskite structure under the shock compression whereas the perovskite structure is transformed retrogressively into the single-chain structure during the process of pressure release.

对回收样品进行的X射线衍射分析结果表明：两发顽火辉石回收样品的主相均是单链状结构硅酸盐，而非钙钛矿结构；另外，回收样品中均未观察到氧化物SiO2 和(Mg0.92， Fe0.08)O的XRD特征谱线；两发MgO+SiO2回收样品中均观察到SiO2和镁橄榄石(Mg2SiO4)而没有氧化物MgO。

The XRD results were just the same as previous researches, which indicated that the main phase of the recovered samples is not perovskite structure, but single-chain structure enstatite. Especially, no evidence of the oxides SiO_2 and Mg_(0.92, Fe_(0.08) O in recovered samples was observed.

在78～115 GPa冲击压力(估算温度为3000～5000K)范围内进行了两发原始样品为Mg_(0.92，Fe_(0.08)SiO_3顽火辉石+铁的冲击压缩回收实验，这是国际上首次采用冲击波回收技术来研究铁与硅酸盐的反应，是本文的又一创新实验设计。

Different escharotic decide the different speed of reaction, thus to cause the great effect on stone carving speed, carving effect, for example, marble whose mainly component is carbonate, so it is better to choose escharotic made from HCI, while for granite , whose mainly component is silicate, it is better to choose escharotic made from HF

腐蚀剂类型的不同又决定了反应速度的差异，进而对雕刻速度、雕刻效果都会生产比较大的影响，例如，以碳酸盐为主要成分的大理石类石材，选择由HCl配制的腐蚀剂比较适宜；而以硅酸盐为主要成分的花岗石类石材，选择由HF配制的腐蚀剂比较适宜。

Acoording to the dense system mortar theory sith micromeritics added to cement to produce impermeable gel with expansive property.The expansive concretepossesses both early expansivity (during 14d water cure) and later expansivity (during 286d shrinkage period in air).

依据与水泥生成超细粒致密系统浆体理论，利用天然非金属硅酸盐矿物与水泥形成不透水凝胶体的特有膨胀性能，研制出高抗渗、抗收缩的TEA－膨胀型防水剂。

Its main existing states include cobaltiferous ferruginous sulphide, oxide, carbonate, sulphate, clay mineral and silicate.

Changsha 410083, P.R.China）Abstract: The crystal structure, wettability and floatability of diaspore and other gangues like kaolite, illite and pyrophyllite were discussed.

摘 要：分析了我国铝土矿中一水硬铝石和铝硅酸盐脉石矿物的晶体结构与表面性质。

Differences of wettability and floatability between diaspore and aluminium silicate minerals are due to the differences of crystal structure between diaspore and aluminium silicate minerals, and of the part Al-O, Si-O bonds, and the metal ions on the surface of the minerals.

一水硬铝石与铝硅酸盐脉石矿物晶体结构的差异、表面断裂的Al-O和Si-O键及表面离子活性区的差别，可影响矿物表面的润湿性与可浮性，类质同象及各种晶格杂质离子也将影响浮选剂与矿物表面的相互作用和矿物可磨性。
