石英

The petrified wood fossils have been preserved for millions of years by the process of petrification, a process which turns the wood into quartz crystal, harder than steel.

石化木材的化石自石化过程起，已经历了数百万年，石化过程会将木材转变成为比钢铁还要坚硬的石英晶体。

The annealing ambient can be pure phosphorus or iron phosphide.

退火是在密封的石英管内纯磷或磷化铁两种气氛下进行的。

The rock mass consists of fresh sericite quartz phyllite or fresh leptynite.

岩体为新鲜绢云母石英千枚岩或新鲜变粒岩。

In this area, foliated metamorphic rocks include slate, phyllite, schist and gneiss. Nonfoliated metamorphic rocks include marble , quartzite and amphibolite.

在该区出露的面理化的变质岩有板岩、千枚岩、片岩和片麻岩，出露的非面理化变质岩有大理石、石英岩、斜长角闪岩。

The phyllite, gold-bearing untramylonite and gold-bearing quartz-vein of PEG geochemistry partition mode are Pt-Pd type.

铂族元素地球化学研究表明，千枚岩、超糜棱岩、含金石英脉铂族元素CI球粒陨石标准化分配模式属于Pt-Pd型。

Fault rocks, microstructures and homogeneous temperature (concentrated around 160℃) of fluid inclusions in the quartz veins shows that the fault belt mainly underwent shallow brittle deformation and the highest-grade dynamic metamorphic rock is mylonitized sericite phyllite.

显微构造、断层岩与石英脉流体包裹体均一温度(集中在160℃附近)均显示，断裂带以浅层脆性变形为主，最深动力变质岩仅为糜棱岩化绢云母千枚岩。

Through the creative research of piezoelectricity of quartz-bearing rocks, the modulus of most kinds of the rocks are given out.

同时还开创性地对含石英岩石的压电性进行了测试研究，得出各类岩石的压电模数值

Granite consists of 20 or more percent quartz, more alkali feldspar than plagioclase.

花岗岩含20%以上的石英，碱性长石多于斜长石。

The quartz pattern study showed that the activity age was early Pleistocene epoch—late Pliocene.

特别是石英形貌分析结果和电子自旋共振测年说明研究区内的断裂的主要活动时期是早更新世—晚上新世。

Brain and blood Al determinations The brain and blood aluminum concentrations were determined by atomic absorption plumbago.

脑组织及血液中铝含量测定准确称取0.1～0.5 g的脑组织或准确吸取0.2～0.5 ml的全血于石英烧杯中，加5～8 ml混酸，同时做空白对照。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
