查询词典 haematite

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。

After analysing the material composing of the haematite, the research adopts acid leaching—replacement processes to utilize and reduce resource.

本研究通过分析赤铁矿中的物质构成，对赤铁矿尾矿采用酸浸—还原工艺，实现固废资源化、减量化的目的。

Electrophoresis measurements of uniform colloid particles including latex and haematite particles have been made in various chemical conditions to test the developed model.

在不同化学条件下，对均匀胶体颗粒(包括聚苯乙烯Latex颗粒和α-Fe_2O_3颗粒)进行电泳测定来验证该模型。

Interpretation of the magnetic parameters suggests roughly constant proportions of haematite and magnetite with a predominance of ferrimagnetic grains in superparamagnetic and multidomain + pseudo singledomain grain sizes.

各监测点磁性参数的测试结果表明，高矫顽力的&赤铁矿&和低矫顽力的&磁铁矿&的含量之比大致变化不大，在这些气溶胶中，在超顺磁、多畴和伪单畴的矿物晶体颗粒中，以亚铁磁性矿物占优。

Chemical analyses of ores sampled from different elevation at the representative Zoujiashan uranium deposit indicate that Fe〓O〓, FeO, MgO and P〓O〓 increase evidently with depth which is related to alteration of haematite, chlorite and apatite, Na〓O and Na〓O+ K〓O also increase with depth, reaching a maximum of Na〓O at 911 meters below the surface, which suggests alkaline alteration increases downwards. At depth of 90 meters below sea level, where the boundary of the two cycles of the volcanic rocks is located, CaO reaches the maximum, representing maximum of alteration of fluorite.

对典型矿床不同富集标高矿体的化学全分析结果表明：随深度增加，Fe〓O〓、FeO、MgO及P〓O〓的含量有明显增高的趋势，这与赤铁矿化、绿泥石化及磷灰石化有关；-90m标高的CaO含量最高，达17.67％，反映这一部位的萤石化最发育；Na〓O及Na〓O+K〓O的含量由浅入深也存在明显的增高趋势，且Na〓O的含量在911m深处为最高，这充分显示碱交代作用从上到下有增强的趋势，而钠长石化在911m处最强烈。

These samples were collected along a main street across the urban area and a mountain route from foot to the top. Results demonstrate that the main magnetic minerals in the street dust are magnetite, maghaemite and haematite with some paramagnetic minerals. Plots of Mrs/Ms vs. Bcr/Bc and Xfd % vs. X ARM/SIRM indicate that the main grain size of magnetic minerals in the street dust are pseudo single domain. The results reveal that the Lanzhou city is more polluted in spring than in summer. The main pollution sources are anthropogenic activities （81.9%） and natural dust （18.1%）, especially the former. The spatial distribution of pollution is controlled by the topography and weather conditions.

结果表明，兰州市街道尘埃中磁性矿物含量较高，主要磁性矿物是铁磁矿、磁赤铁矿和赤铁矿，并伴有少量顺磁性矿物；磁性矿物粒度主要是准单畴；市区污染春季较夏季严重，春季高频率的强沙尘暴可能带来了更多的磁性矿物；兰州市污染物的沉积和分布在很大程度上受到气象条件和地形地貌格局的影响，市区每个盆地东端高于其它地区；兰州市污染以人为活动产物为主，人为活动贡献约为81.9％，其中包含交通约22.6％的贡献，自然降尘贡献约为18.1％；特殊的地形和气象条件，使得兰州市区的大气环境容量比平原城市的环境容量小得多，进而导致严重的大气污染。

The glossary provides information relating to commonly occurring metals and ores such as gold, copper, chalcopyrite, haematite, pyrite, molybdenite and sphalerite, and gives details of some common mineral assemblages.
