最近在西藏罗布莎村豆荚状铬铁矿石中发现一个由70~80种矿物组成的地幔矿物群，其中包括新矿物罗布莎矿，还有金刚石、柯石英、碳硅石、方铁矿、以及Fe-Si相矿物。

6GPa, 1000～1200℃, 2-48h. It is noted that according to the mechanism proposed above, it is own to the local high pressure and local high temperature coaction which making the SiO〓 surface as high energy state, therefore coesite synthesized in the lower conditions.

值得特别指出的，如上面有关高能机械球磨作用机制的研究中知悉，在高能球磨碰撞过程中可产生4～6GPa的局部高压和200～600℃的局部高温，正是局部高压和高温使得SiO〓形成表面高能态的非晶原材料，从而可以比通常低很多的高压高温条件合成出柯石英。

This study was to find a new cationic collector with better selectivity and collectability than alkyl amine to realize the selective flotation of silica from the iron ore.

Baihua igneous complex consists mainly of pyroxenite-gabbro-diorite-quartz diorite. They form a complete comagmatic evolutionary series. The tectonics environment discrimination of trace element geochemistry reveals the igneous complexs formed in an island-arc setting.

百花岩浆杂岩体主要由辉石岩－辉长岩－闪长岩－石英闪长岩组成，构成较完整的同源岩浆演化序列，地球化学研究表明其形成于岛弧构造环境。

The Liushuigou intermediate-basic meta-igneous complex at Guanzizhen, Tianshui, is composed mainly of metagabbro-metagabbro diorite-metadiorite, and the Baihua basic meta-igneous complex consists mainly of pyroxenite-gabbro-diorite-quartz diorite. They form a relatively complete comagmatic evolutionary series.

提要：天水地区关子镇流水沟变质中基性岩浆杂岩主要由变质辉长岩—辉长闪长岩—闪长岩组成，百花变质岩浆杂岩主要由辉石岩—辉长岩—闪长岩—石英闪长岩组成，构成较完整的同源岩浆演化序列。

Zn-diffused high power 650 nm AlGaInP/GaInP material with compressively strained multi-quantum-well active layer was fabricated. The zinc diffusion was used on the material facet in a sealed quartz tube. Photoluminescence spectra shows 175 meV blue-shift in the Zn diffusion area, which is transparent for 650 nm laser emission.

利用石英闭管法对金属有机化学气相沉积外延生长的应变量子阱650 nm AlGaInP/GaInP材料进行选择区域扩Zn，使扩Zn区域的光致发光谱的峰值蓝移达175 meV，形成对650 nm波长激光器的高透腔面，有益于减少激光器腔面光吸收，增加了激光器退化的光学灾变损伤阈值。
