橄榄石

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。

The forsterite ore deposit in Yichang of Hubei Province, being one of the limited large ore deposits across the Mainland China, is used to produce molding sand.

宜昌镁橄榄石矿，是我国为数不多的大型矿床之一，用其矿石生产的镁橄缆石型砂。

We first built a compact self-started HRR Cr:forsterite laser at 100-MHz for the application of portable clinical use operating around 1230 nm.

首先，我们建造了一个自启动且小巧的高重覆铬贵橄榄石雷射，它的重覆率为100百万赫兹，工作波长在1230奈米附近，是一个适用於可携式医疗诊断用途的雷射光源。

ABSTRACT One of the new laser crystals drawing much attention in recent years is the synthetic chromium-doped forsterite, for which Cr ions can realize the laser operation in a new wavelength range reaching up to 1340 nm.

人工掺铬镁橄榄石晶体是近年来受到重视的一种激光晶体，它能使铬离子实现新波段的激光运转。

To replace one magnesium atom with two hydrogen atoms increases the electron transport of forsterite crystal, and the hydrous forsterite dose not become a conductor.

两个氢原子替代了一个镁原子后，增强了晶体结构中的电子运移，但是含水镁橄榄石仍然是不导电的。

We have tested several terrestrial samples, such as Mo, Ti, Ni, ilmenite, titanite, rutile, pyrite, forsterite and melilite. We have also attempted to analyze our first meteorite sample.

我们已经测试了许多地球标本，包含了钼、钛、镍与钛铁矿、楔石、金红石、黄铁矿、镁橄榄石和方柱石，同时也尝试了我们第一个陨石的标本。

Xixia, the amount of ore contained in the Xixia King within 6.9 kilometers long, 2.1 kilometers wide region, the total ore reserves of 10 million tons, are Asia's largest open-air forsterite deposits, and with the coexistence of chromium ore.

西峡，此矿蕴含量在西峡景内长6.9公里，宽2.1公里的区域内，总矿储量达10亿吨以上，是亚洲最大的露天镁橄榄石矿床，且与铬矿共存。

The purpose of this thesis is to explore other yet undiscovered contrast origins and unused contrast agents of third-harmonic-generation inside biological tissues, and apply to the preliminary studies of medicine based on a nonlinear laser scanning microscopy system using a femtosecond Cr:forsterite laser centered at 1230-nm.

这篇论文的目的是利用了以中心波长为1230nm的铬贵橄榄石雷射做为光源的非线性雷射扫瞄显微镜系统去探索生物体中其他仍未被发现的三倍频对比来源以及尚未被使用的三倍频外加显影剂，并初步的应用於医学研究上。

The results showed that the first phase of sample is μ-cordierite and the final phases are α-cordierite, forsterite, MAT and rutile .

结果表明，样品初晶相为μ-堇青石，最终结晶相除α-堇青石外，还有少量的镁橄榄石、镁铝钛酸盐以及金红石相。

The parental magmas of the Wudangshan Group and Yaolinghe Group basic lavas from Wudangshan area were then subjected to shallow level gabbroic (cpx+plag±ol) fractionation and the chemical evolution of the basic lavas and basic dykes from other areas was controlled by a clinopyroxene+olivine fractionation.

武当山地区的武当山群和耀岭河群基性熔岩的母岩浆经受了浅层位辉长岩质(cpx+plag±ol)分离作用，而其他地区基性熔岩和基性岩墙的化学演化则是受控于单斜辉石±橄榄石分离作用。

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。
