片蚀

Actinolite and pyroxene phenocrysts separated respectively, from chlorite-actinolite schist and altered pillow basalt in the E'rou area of the eastern part of the Shuanghu-Longmuco suture zone, yield well-defined 40Ar/39Ar plateau ages of 235.9±2.6 Ma and 232.5±2.4 Ma. These nearly identical ages are interpreted as defining the age of the tectonothermal event of subduction-related collision along the Shuanghu-Longmuco suture zone.

在藏北龙木错－双湖缝合带东段双湖鄂柔地区，获得绿泥阳起石片岩中阳起石矿物的40Ar/39Ar坪年龄为(235.9±2.6)Ma和枕状玄武岩中蚀变辉石斑晶的40Ar/39Ar坪年龄为(232.5±2.4)Ma，两个年龄具有极好的一致性，记录了中三叠世晚期－晚三叠世早期沿龙木错－双湖缝合带发生俯冲碰撞作用的构造－热事件。

Aquatint:It is an etching process on copper or steel by means of nitric acid.

水彩色调：用硝酸在钢片或铜片上作腐蚀的蚀刻法。

Under the electron microscope, it is revealed that the kaolinite crystals are low automorphic and distinctly corroded, the halloysite crystals are mostly in shapes of tube, rod and tabular-flake, and illites are in ultramicrograin aggregate.

电子显微镜下，高岭石的晶体自形程度差溶蚀现象显著（普遍形成港湾状、浑圆状）；埃洛石晶体多呈管状、棒状以及板片状；伊利石呈超微细颗粒集合体（不规则的鳞片状、浑圆状及板条状等）。

Simulation results show that the thickness non-uniformity of SiO2 films was less than 8.5% over the convex surface of a dummy dome.

模拟结果显示：头罩外表面制备的SiO2薄膜其厚度不均匀性小于8.5%；雨蚀测试后，蓝宝石验证片的平均透过率损失小于1.0%。

Based on the study on the reformation of Dawsonite sandstones with CO2 fluids at different temperature (100℃, 200℃ and 300℃) and different the CO2/H2O/sandstone systems in inclosed containers, it is suggested that the corrosion intensity of dawsonite sandstone will gradually be enhanced as the temperature increases.

不同温度（100℃，200℃和300℃）下CO2流体对含片钠铝石砂岩的改造作用研究显示：随着温度的升高，砂岩的溶蚀、溶解程度逐渐增强，样品中片钠铝石的稳定性逐渐减弱。

The drawing is then pressed by hand onto a sheet of absorbent paper or printed on an etching press.

它使用墨水或油墨在玻璃或一片金属、石头上作画，然后用手压抹或者施行蚀刻法印刷在纸张上。

The major auriferous veins of Jizhao gold deposit occur in the compressive break belt of aft EW-extending fold axis.The host rocks are sillimanite biothe-schist and dimicaceous schist of the second Member,Dashiqiao Formation.

鸡爪金矿主要金矿脉赋存在近东西向的褶皱轴部的挤压破碎带中，容矿岩石为大石桥组二段矽线黑云片岩、二云片岩，围岩蚀变为硅化、钾长石化、黄铁矿化。

The protoliths of the chlorite-actinolite schist were mainly volcanic-sedimentary rocks enriched in basalt. The chlorite-actinolite schist and the altered pillowbasalt are characterized by high contents of TiO5, P2O5 and MgO, LREE-enriched patterns with negative Eu anomalies, and "tumescence" patterns for trace elements with enrichment in Nb, Ta and Ti; these are typical characteristics of "OIB-type" alkaline basalt.

绿泥阳起石片岩的原岩主要为富含玄武岩的火山－沉积岩系，绿泥阳起石片岩和蚀变枕状玄武岩具有TiO2、P2O5、MgO含量较高和LREE富集型、无Eu异常，以及"大隆起"微量元素配分模式和富集Nb、Ta、Ti元素等地球化学特征，显示为较典型的洋岛型碱性玄武岩性质。

Often called planar transistors, they are built on the surface of a silicon wafer by using a manufacturing process that precisely deposits and then etches away different insulating, conducting and semiconducting materials with such precision that the industry is now approaching the ability to place individual molecules.

通常被称为「平面电晶体」，运用一个将电晶体精确放置在晶片的表面，蚀刻掉不同绝缘、导体和半导体材料的制程，以此精密技术业界将能够在晶片上面放置个别分子大小的材料。

The chlorite ores altered from mica schists are either massive or schisteous ores with gray greenish and dark gray colors.

而由云母片岩蚀变而来的绿泥石矿石呈块状或片理状、颜色为灰绿色和深灰色。

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。
