In the high-grade metamorphism and anatexis process, in which sapphirine was formed, the multistage crystallization of minerals resulted in the complexity of the mineral association, such as the differentiation of leuco-and melano-components. Generally, the mafic-rich minerals formed earlier, and the differentiation of magnesio-and iron-components is responsible for the earlier presence of ironrich minerals, i.e., magnesio-rich minerals crystallized later, thus the successive associations of multistage occurred.

在形成假蓝宝石的高级变质-深熔作用过程中，岩石矿物组合的变化主要是多阶段变质造成的，如浅-暗色组分发生了分离，其中含镁铁组分多的矿物较早结晶，而镁铁组分的分离使得相对富Fe的矿物较早结晶，即晚期形成的镁铁质矿物更富Mg组分，并形成递进演化的不同阶段的组合。

Based on a systematic study of a considerable number of polished ore sections as well as ICP-MS and electron microprobe analyses, the authors have found that the main sulfide minerals include galena, iron-poor sphalerite and chalcopyrite, whereas silver minerals are composed chiefly of native silver, pyrargyrite, argentite, polybasite, and argentiferous freibergite.

文章首次对其矿石矿物进行了系统的研究，通过对大量矿石光薄片观察、等离子质谱和电子探针分析，表明具有工业意义的硫化物主要有方铅矿、贫铁闪锌矿、黄铜矿，银矿物主要有自然银、深红银矿、辉银矿、硫锑铜银矿、含银黝铜矿，它们与硫化物共生，多沿方铅矿、贫铁闪锌矿等颗粒间或者裂隙产出。

In this paper different concentrations of iron boride powders were put into the iron - based metal catalyst to get different kinds of boron-doped diamonds with high thermal stability under high temperature and high pressure conditions.

When the temperature is less than 15 K, the PBTCA-Nd~(3+) complex is a ferromagnet, otherwise, it is a diamagnet. Both PPHBT-Nd~(3+) and PPHPHN-Nd~(3+) exhibit the characteristic of soft-magnetic materials at low temperature, the Curie-Weiss temperature are 80 K and 150 K, respectively.

实验结果表明，含咔唑聚合物的稀土配合物PBTCA-Nd~(3+)表现出特殊的软铁磁性，具有一个磁转变温度15 K，低于此温度时配合物是个铁磁体，反之，为抗磁体。

The following year, Pourcel began industrial-scale production of "spiegeleisen", a pig-iron containing a high percentage of manganese, and in 1875 he started the commercial production of ferromanganese with a 65% manganese content.

第二年，帕萨开始了镜铁的工业化规模生产。1875年，他开始了含锰量为65%的锰铁的商业生产。

The electrochemical properties of the corrosion of 430 ferrite stainless steel with different RE contents in the 3.5wt% NaC1 solution were studied by means of EIS (electrochemistry impedance spectroscopy). And the characteristics of textural component were quantitatively analyzed by the orientation distribution functions and inverse pole figure.

The results showed that the amounts of base cations leached from calcareous soils and coastal solonchak were lower than the cation exchange capacity and the releasing amounts of Al3+ being lower than 0.40mmol·kg-1 all the way under the treatment of simulated acid rain with each pH value from 2.5 to 5.6,so the H+ buffering...

结果表明，石灰土和滨海盐土的阳离子淋溶量低于阳离子交换量，土壤主要处于阳离子交换缓冲范围和碳酸盐-硅酸盐缓冲范围，Al释放量一般低于0.40mmol·kg~(-1)，铁铝土纲系列土壤在阳离子释放总量超过阳离子交换量后，淋溶液pH值急剧下降，此时Al淋溶量明显增加，质子缓冲转向Al缓冲范围，其释放量决定于土壤富铁铝化程度的高低和活性Al含量的多少，紫色土在低pH模拟酸雨淋溶下，由于含大量硅铝率较高的易风化原生或次生矿物，盐基释放量高于CEC，但Al释放量未明显增加，淋溶液pH也较稳定，土壤尚处于矿物风化为主的硅酸盐缓冲范围。

Through the contrast analysis on the chemical constitution of the magnetic iron ore and the plagioclaseamphibolite in Nanling ultra poor magnetite, and the analysis of graphs of and (FeO+Fe2O3+TiO2)Al2O3MgO, combining the geological features of mining area and the ore body characteristics, the conclusion can be drawn as follows: the plagioclaseamphibolites including magnetite and the plagioclaseamphibolite in Nanling mining area are formed from the oceanic tholeiite with rich iron after the deteriorating, and their genesis types should be the ultrapoor iron deposit of weathered residual origin.

通过对南岭超贫磁铁矿的磁铁矿石、斜长角闪岩化学成分的对比分析，结合矿区地质特征和矿体特征，对矿体进行n-n和w( FeO+Fe2O3+TiO2)-w(Al2O3)-w 图解分析，结果显示南岭矿区的含磁铁斜长角闪岩和斜长角闪岩是大洋富铁拉斑玄武岩经变质作用而形成的，矿床的成因类型为风化残积型超贫铁矿床。
