赤铁矿

The depressive behavior of (NH4)2 SiF6 on iron-containing silicate gangue, aegirine, in hematite flotation with sodium oleate as collector was studied.

研究了油酸钠为捕收剂的赤铁矿浮选中，水玻璃与氟化物等抑制剂对含铁矽酸盐脉石矿物霓石(NaFe2 SiO6)的浮选抑制行为。

It demonstrated that the hydroxy organic acids substituted with-OH,-SH at α—C such as lactic acid, Hydroxy-acetic acid, mercapto-acetic acid, glyconic acid have good selectivity for separation of hematite and aegirine pka values of organic acids fall down because of the-I inductive effect of-OH or-SH, and lie at the pH range between two minerals point-zero-charge. As a result, the depression ability of them was enhanced, and a cyclo-pentyl chelate was formed when this organic acids acted with Fe〓 on the minerals surface.

发现在α位具有-OH、-SH等取代基的短链一元羧酸（乳酸、羟基乙酸、巯基乙酸，葡萄糖酸）对赤铁矿与钠辉石的浮选分离具有优良的选择性抑制作用，-OH、-SH的-I诱导效应导致有机酸的pKa值下降并落在两种矿物零电点之间，使其抑制性能增强，并与矿物表面的Fe〓形成稳定的五元螯合环。

Sawn, Calibrated, 4-cut and 6-cut....+ 1 mmEdges also can be chamfered / bevelled. Chamfering removes whiteness and chipped edges. This looks very good. Chamfering is a simple process in which a polishing brick is run at an angle of 45 ?.

这种类型的人造石材的生产工艺与陶瓷的生产工艺相似，是将斜长石、石英、辉石、石粉及赤铁矿粉和高岭土等混合，一般用40%的粘土和60%的矿粉制成泥浆后，采用注浆法制成坏料，再用半干压法成型，经1000℃左右的高温焙烧而成。

The A and B components remanent magnetization were loaded by goethite and maghemite respectively, the C component remanent magnetization was carried by the magnetite in the sandstones and were loaded conjunctly by the magnetite and hematite in the mudstones and muddy sandstones.

它们的存在并不影响岩石原生剩磁的分离，也不影响原生剩磁信号的稳定性和获得的古地磁数据的可靠性。16个砂岩采点中不能分离出C分量，是由于后生的赤铁矿彻底改变了由磁铁矿携带的原生剩磁组分，在高密度采样的情况下剔除这些采点并不影响古地磁极性柱的构建和解释。

It sense d a min eral called hematite that offen forms under wet conditions.

它还发现了被称为赤铁矿的矿石的存在，这种矿石通常是在潮湿条件下形成。

Nobody knew what the haematite would look like , or what kind of form it might show up in .

没人知道这些赤铁矿看上去会是什么样，或将以怎样的形态进入人们的视野。

Nobody knew what the haematite would look like, or what kind of form it might show up in. It turned out to be the main

没人知道这些赤铁矿看上去会是什么样，或将以怎样的形态进入人们的视野。

The decision was based on spectral measurements by the orbiting Mars Global Surveyor, which showed an unusual concentration of haematite, a form of iron oxide.

决定建立在由围绕火星飞行的火星全球探测器所做出的光谱测量基础上，其中显示了不同寻常的赤铁矿含量。

On Earth, any natural metallic iron rusts in our wet, oxygenated environment, so we rely on iron oxides such as haematite to make steel.

在地球上湿润并充斥着氧气的环境中，任何天然的金属铁都会生锈。因此，我们依靠象赤铁矿中的氧化铁来制造钢材。

The morphology, character and distribution of Navajo haematite concretions allow us to infer host-rock properties and fluid processes necessary for similar features to develop on Mars.

地球上纳瓦霍沙岩与火星上Meridiani Planum之间的类比表明，火星上积累的球状赤铁矿是在有一种可渗透的主体岩石、地下水流和一个化学反应锋面的条件下形成的。

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。
