镁橄榄石

The variety of olivine include olivine, peridot, flinder diamond, forsterite, fayalite, dusk emerald and sinhalite.

橄榄石的种类包括（贵橄榄石、黄玉、镁橄榄石、铁橄榄石、"黄昏祖母绿"和硼铝镁石）。

It indicates that electrical conduction ofα- andβ-phases is not caused by transport of protons bounded at Mg tetrahedral position.

这表明镁橄榄石的导电可能不是由镁离子位置上的质子移动引起的。

As they cool off,they transform into forsterite, a type of silicate crystaloften found in comets in our solar system.

在冷却的过程中，它们转化成了镁橄榄石，镁橄榄石是在我们太阳系的彗星中经常被发现的一种硅酸盐晶体类型。

The sound velocities of hydrous forsterite reduce by 3.1-7.1% and 3.6-9.7% respectively at 0-14 GPa with 3.2wt% water.

在0-14GPa的压力下，含3.2wt%水的镁橄榄石比不含水镁橄榄石的Vp和vs值分别降低了3.1-7.1%和

The thermal shock resistance of the brick is expected to improve as a result of bigger bulk density, lower thermal expansion coefficient, phase transformation of fused MgO-ZrO2 eutectic powder, formation of magnesiaalumina spinel and forsterite.

材料性能的变化主要与电熔MgO-ZrO2共晶砂的体积密度大、热膨胀系数小、氧化锆的相变、镁铝尖晶石和镁橄榄石等物相的生成相关。

Adding water in forsterite crystal cell decreases bulk modulus, shear modulus, and sound velocities of forsterite.

镁橄榄石晶格中存在水会使镁橄榄石弹性模量及波速降低。

At the same time, the K, G, Vp, and Vs of forsterite decreased too because of density decrease 3.0% caused by H atoms replacing Mg atoms in the crystal. Water also increases the total energy of the forsterite system, i. e. the crystal stability and the power of bond were reduced at high pressure and temperature.

在常温常压下，2个氢原子置换1个镁原子会使镁橄榄石的密度降低3.0%，是波速及弹性模量减小的原因，同时使镁橄榄石体系的基态总能增加，降低矿物的稳定性和键之间的强度。

The feasibility of producing forsterite refractory with hi-silicon iron tailings and hi-magnesium raw material was discussed, the synthesis reaction process was studied by laboratory experiment, and the method of producing forsterite refractory and lightweight forsterite refractory by use of iron tailings were offered.

论证了利用鞍山地区高硅型铁尾矿和高镁原料合成和制备镁橄榄石材料的可行性，实验研究了合成反应过程，提出以铁尾矿生产镁橄榄石耐火材料和轻质保温耐火材料的方法。

In this thesis, the crystal structure and phase transition behaviors of a andβforsterite (Mg2SiO4) at high temperature and high pressure were investigated by the first principle calculations and the quasi-harmonic Debye model. Variations of elastic properties, band structure, density of state, band gap ofαandβforsterite with pressure were calculated, and the effect ofα/βphase transition on these characters was analyzed. The effects of water on elastic modulus, sound velocity and band gap of forsterite were also simulated. Finally, the effect ofα/βphase transition and water on seismic discontinuity in earth was discussed.

通过第一性原理结合准简谐德拜模型研究了α和β镁橄榄石的高温高压结构及相变特征；计算了α和β镁橄榄石的弹性模量、波速、电子带结构、带隙等随压力的变化规律，并探讨了相变对这些性质的影响；研究了水对α镁橄榄石弹性模量、波速和带隙的影响；探讨了水对地幔中不连续层的作用以及矿物相变对过渡带波速不连续的作用。

The phase constitutions of Magnesia-based dry vibratable materials is designed by the analysis of phase equilibrium digrams, in which the periclase is host crystalline phase, the Spinel, Forsterite and Monticellite et al are the bonding phase in matrix.

本文通过相图分析设计了镁质干式振动料的物相组成，其主晶相为方镁石，基质为镁橄榄石、尖晶石及少量的钙镁橄榄石等。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
