水锰矿

Based on the characteristics of paragentic manganese minerals in silver-gold ore of Guandi,the chemical phase separation selective solvent s of Al(NO_3)_3 was chosen for manganese carbide phase and H_2SO_4-KF-HF for manganite and braunite phases.

根据官地银金矿中锰矿物的共生组合情况，引用A l(NO3)3溶液作碳酸锰矿物的选择性溶剂，H2SO4-KF-HF混合溶液作水锰矿、褐锰矿的选择性溶剂，于滤渣中测定软锰矿。

Vemadite and 1 nm manganate are the two main manganates in the polymetallic nodules, they both have the characteristic X ray diffraction pattern in 0.24 nm and 0.14 nm, therefore much attention should be paid in order to distinguish these two manganates during mineral analysis.

水羟锰矿和1nm锰矿相是多金属结核中最主要的两种锰矿物，它们两者均有0.24nm和0.14nm这两条特征X射线衍射峰，因此在对结核进行锰矿物相的鉴定中要注意把它们区分开。

The crystal structure of the marine 1 nm manganate is quite different with that of the land base todorokite, and it has more similarities with the synthetic 1 nm manganate of buserite instead, therefore the marine 1 nm manganate and todorokite are the distinct manganates. The 1 nm manganate can be transformed into 0.7 nm manganate by losing some water caused by drying, and the 0.7 nm manganate might not be the original manganate phase in polymetallic nodules, but is more likely to be the phase transformation product of 1 nm manganate.

大洋多金属结核中的1nm锰矿相常以陆上钡镁锰矿命名，但两者在晶体结构等方面有很大的差别，并不属同一种矿物，1nm锰矿相与人工合成的布塞尔矿却有更多的相似性。1nm锰矿相会因干燥失水而相变成0.7nm锰矿相，因此结核中的大多数0.7nm锰矿相很可能不是原生矿物，而仅仅是1nm锰矿相的相变产物。

Microscopic structures of Zn surface complexes adsorbed at the manganite water interface were studied using extended X ray absorption fine structure spectroscopy.

用延展X光吸收精细结构光谱研究了重金属Zn在水锰矿上吸附产物的微观结构及其吸附机理。

Quantitative analysis of the EXAFS spectra showed that, in a 0 1mol/L NaNO 3 solution of pH 7 5, Zn was adsorbed onto the solid surface by sharing the oxygen atom in the hydrous Zn 2+ ions and in the structural unit MnO 6 on the manganite surface.

结果表明，Zn 水锰矿体系中(pH 7 5 ，0 1mol/LNaNO3 介质，2 5℃)，Zn2 +主要是通过共用水合Zn2 +的O原子及水锰矿表面上的O原子形成Zn—O键，从而结合到水锰矿固体表面上的。

Quantitative analysis on the EXAFS spectra showed that Zn was adsorbed onto the solid surface in form of octahedral hydrated Zn ions, which were linked to the octahedral Mn06 of manganite by sharing oxygen atoms, with an average bond length R(subscript Zn-O)=(2.01±0.01)×10^(-10) m.

EXAFS结果表明，Zn主要是通过共用水合Zn离子的O原子及水锰矿表面上的O原子形成Zn-0键，从而结合到水锰矿固体表面上，其平均Zn-O原子间距为(2.01±0.01)×10^(-10)m。

The results show that the conversion rate of lithiophorite decreases with decreasing reaction temperature. Lithiophorite can be obtained at pH values from 5.0 to 9.0, but the circumneutral pH is more favorable for formation at atmospheric pressure.

水钠锰矿向锂硬锰矿的转化速率随着反应温度的降低而减少，在pH5-9的范围内锂硬锰矿均可形成，但中性条件最适合锂硬锰矿的形成。

Indeed, the Grand Canal was constructed partly utilizing the pre-existing channels connecting these lowland swamps and lakes (3) Several rivers have produced deltaic forms on the western side of the lakes;(4) A series of artificial islands have been constructed upon the natural bars or barriers located in the lakes and wetlands, and are locally termed Duo, Dun or Wei (meaning artificial bars or crossways in Chinese).

钻孔B/M界线之下(4078 m～4530 m)的泛滥平原河湖相沉积物中局部地段富含铁锰鲕粒，其主要矿物组成为蛋白石、铁的氢氧化物(包括纤铁矿、水纤铁矿、针铁矿、水针铁矿，统称褐铁矿)、铁锰氧化物(包括硬锰矿和软锰矿，以硬锰矿为主)及极少量的细小碎屑矿物(钾长石、蚀变黑云母、含铁白云母、锆石、独居石、金红石和含钛磁铁矿)。

On the other hand, Cu, Co and Ni are all present in manganese phase in the hydrogenic nodules.

这些过渡金属元素在成岩作用形成的结核中的存在与铁锰结核中锰矿物和铁的氧化物、氢氧化物的晶体化学特征密切相关，而在水成作用形成的铁锰结核中的富集与锰矿物和铁的氧化物、氢氧化物的晶体化学特征关系不大。

Ceramics. such as doped rare-earth manganites exhibit extremely high values for this effect.

陶瓷。例如这个作用的被掺杂的稀土元素水锰矿展览极端上限值。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
