赤铁矿

The XRD and SEM/EDX analyses demonstrated that minerals in Beijing PM10 were clay and quartz, plagioclase, potassium feldspar, albite, calcite, dolomite, hematite, pyrite, magnesite, gypsum, and laumontite, in descending order.

XRD及 FESEM/EDX单颗粒分析表明，北京市PM10中的矿物颗粒以粘土矿物和石英为主，另外还有斜长石、钾长石、钠长石、方解石、白云石、赤铁矿、黄铁矿，菱镁矿、石膏、浊沸石等，矿物颗粒表面的硫化现象常见。2002特大沙尘暴颗粒物中的矿物的含量自大到小分别为粘土矿物、石英、斜长石、方解石、钾长石、赤铁矿、黄铁矿、角闪石和石膏。

The result shows that the ferrospheres are mainly composed of hematite and magnetite,with a small amount of maghemite and magnesioferrite.

结果表明：磁珠中含铁矿物主要有赤铁矿、磁铁矿、磁赤铁矿和镁铁矿。

In sinter s,MgO mainly distributes in ferric phase and reacts with hematite and wustite generating magnesioferrite and MgO-bearing wustite.

烧结矿中MgO主要分布于铁相中与赤铁矿和富士体固溶形成镁质赤铁矿和镁质富士体，Mg2+在硅酸盐粘结相中的固溶量很低。

Surfaces of mineral grains investigated by the SEM method demonstrate differences in flocculation. Measured polarization curves allowed to reveal unequal electrochemical processes on surfaces of magnetite, hematite, and martite particles. Xray analysis and Mssbauer data also confirmed the changes in compositions of the ores before and after applying of the electrochemical method.

采用扫描电镜技术研究矿物颗粒表面，发现其在絮化作用中的差异；偏极化曲线的测定可以揭示磁铁矿、赤铁矿和假象赤铁矿等矿物表面的不均等电化学过程； X射线分析和穆斯堡尔谱数据亦可确定电化学处理前后矿粉样品成分的变化。

A lot of hematite and martite lean intergrowth is existed in magnetic concentration tails in concentration mill of Laiwu mine Co ,Ltd For recovering these iron mineral the medium intensity magnete separator is used,and the comprehensive metal recovery factor is increased by an average 1 17%,the grade of tails is decreased by 0 5%~1 0%,the profit is up to 0 77 million yuan

莱矿选矿厂磁选尾矿中含有大量赤铁矿、假象赤铁矿贫连生体，为回收这部分铁矿物，采用了中磁场分选设备，使综合金属回收率平均提高 1.17%，尾矿品位降低 0 。5 %～ 1.0 %，年经济效益 77万

Under optical microscope,the observational result indicates that the peach blossom stone samples from Gao Mountain contains transparent and distransparent minerals which forms pealike and red spots.

光学显微镜的观察结果表明，高山桃花石样品中存在透明和不透明矿物，其中不透明矿物形成了艳丽的红色斑点；XRD测试表明，样品的矿物组成为地开石、赤铁矿、石英以及少量的叶腊石；拉曼光谱测试结果表明，样品的基质部分为地开石，结晶形态完好的红色矿物颗粒与呈浸染状的红色部分均为赤铁矿，无色透明的矿物颗粒为石英。

Under optical microscope, the observational result indicates that the peach blossom stone samples from Gao Mountain contains transparent and distransparent minerals which forms pealike and red spots. The XRD testing result indicates that the mineral compositions in the samples are dickite, hematite, quartz and a little pyrophyllite. LRM testing result shows that the basic part of the samples is dickite, the red minerals with both well crystal shape and dip dye shape are hematite, and colourless and transparent mineral grains are quartz.

What is more, the distributing characteristics that the hematite being dip-dye shape commonly surrounds the well hematite crystal, cause the red sports in the peach blossom stone from Gao Mountain different shade and size.

呈浸染状的赤铁矿多围绕晶形完好的赤铁矿分布，该分布特征决定了高山桃花石中的红色斑点有大有小，有深有浅。

Based on a brief analysis of the genesis of hematite, the authors hold that hematite in red granite was mostly produced under the condition of high oxygen fu gacity.

本文对赤铁矿的成因作了简要分析，认为红色花岗岩中的赤铁矿大多为高氧逸度条件下的产物。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
