石英脉

Which has become a common impurity of quartz sand and pyrite nails, but also structural breccias (often as a "chicken blood" package, with hard texture and a soft) and late finePulse (mostly to the low hardness of stone or pyrophyllite open nature, its main impact there is beautiful).

其中常见的杂质有成为砂钉的石英和黄铁矿，也有构造角砾（常为&鸡血&包裹，质地有硬有软）和后期细脉（多为硬度不高的地开石质或叶蜡石质，其存在主要影响美观）。

Based on Stuart et al.'s electron density evolution equation, the electron density evolution process in fused silica film irradiated by short-pulse laser for τ∈[0.015] ps were studied by means of numerical method. The effects of initial electron density N and laser pulse width τ on laser threshold intensity I and damage threshold fluence. F were analyzed respectively.

基于STUART等人的电子密度演化方程，运用数值模拟方法，研究了脉宽为τ∈[0.01， 5]ps范围内单脉冲激光作用下熔融石英薄膜中电子密度演化过程；讨论了初始电子密度、激光脉冲宽度对阈值功率密度和阈值能量的影响；分析了初始电子密度、激光脉冲宽度对多光子离化及雪崩离化的影响。

The raw materials were mainly vein quartz, sandstone, flint and rock crystal, most of which were collected from the river-bed and the hill slopes near by.

制造时期的原料有脉石英、砂岩、燧石和水晶等，大多采自附近的河床和山坡。

When a vein of quartz or magma is located, the character may wield his pick

当一个脉石英或岩浆的位置，性质可能行使他的选择

When a vein of quartz or magma is located, the character may wield his pick or shovel and begin digging out a section.

当一个脉石英或岩浆的位置，性质可能行使他的选择或铁锹，开始挖了一节。

No report about the analogous object in meteor ite has been seen, The mineral constituents of the vein are quartz, muscovite, illite (which was discovered firstly in meteorites), chlorite and some opeque minerals.

有关类似物质在其它陨石中的报道尚未见到。这条脉中的矿物组成有石英、白云母、伊利石（此矿物第一次被发现在陨石中）、绿泥石和一些不透明矿物。
