青石

Within a few hours, you have enjoyed the green valleys, with their rivers, find old bridges, pleasant villages, hanging woods, smooth fields; and then the moorland slopes, with their rushing streams, stone walls, salty winds and crying curlews, white farmhouses; and then the lonely heights, which seem to be miles above the ordinary world, with their dark tarns, heather and ling and harebells, and moorland tracks as remote, it seems, as traits in Mongolia.

在几个小时的时间里，你就可以有幸领略到苍翠欲滴的山谷，涓涓小河流淌其中；你同样可以发现精致的古桥、舒适的村落、茂密的森林、平坦的田野；然后还有沼地的小山坡，带着奔泻的小溪、青石的古墙、略带咸味的海风、啼鸣的麻鹬、白色的农舍；再加上荒寂的高地，它们比平地高出几英里，上面布满黑色的深谭，遍地都是美丽的石南和蓝铃；最后还有沼地小径，它们和蒙古一样幽远。

The results show that glass ceramics with thermal expansion coefficient of 5.11×10^(-6)℃, major phase of α-cordierite and ε=5.5, tan σ=2.1×10^(-4) can be prepared by the addition of 3.6% alkalis (Li2O+Na2O), and Li2O occupies 1.8%. With Li2O substitution for Na2O, spontaneous crystallization is obviously enhanced, and temperature of the first crystallization peak decreases from 950℃ to nearly 900℃, but the crystallization temperature of the second peak was not varied. With the increase of Li2O content, mixed alkali effect can be observed from the thermal expansion coefficient and dielectric loss curve which decreases first and then increases. Dielectric constant decreases monotonously with the increase of Li2O content.

研究结果表明：Li2O和Na2O总含量为3.6%，其中Li2O含量为1.8%时，微晶玻璃以α-堇青石为主晶相，热膨胀系数为5.11×10^(-6)℃，微波频率下介电常数ε为5.5，介电损耗tanσ为2.1×10^(-4)；随着Li对Na的取代，玻璃的析晶能力增强，初始析晶峰温度从950℃降至900℃左右，但没有降低第二析晶峰温度；随着Li2O含量增加，热膨胀系数及介电损耗都出现明显的混合碱效应，曲线呈现先降低后升高的变化趋势；样品的介电常数随Li2O含量增加单调降低。

The results show that glass ceramics with thermal expansion coefficient of 5.11×106 ℃, major phase of α-cordierite and εr=5.5, tan σ=2.1×104 can be prepared by the addition of 3.6% alkalis(Li2O+Na2O), and Li2O occupies 1.8%. With Li2O substitution for Na2O, spontaneous crystallization is obviously enhanced, and temperature of the first crystallization peak decreases from 950 ℃ to nearly 900 ℃, but the crystallization temperature of the second peak was not varied.

In those stones I saw thundering war drums, fluttering flags, and brave villagers raising iron halberds against invaders, their blood staining their clothing and seeping into the granite rampart.

在那些石头里，我仿佛看见了战鼓擂擂、旌旗猎猎，勇敢的寨民们举起铁戟抵抗外敌，鲜血染红了他们的衣衫，渗入青石城墙里

It is distributed widely in igneous rocks, metamorphic rocks and pegmatites, but is seldom concentrated to form independent cordierite deposits.

堇青石作为一种天然矿物已被研究多年，它广泛分布于岩浆岩、变质岩和伟晶岩中，但确很少富集成矿。

And then the TiN crystal particles can act as heterogeneous nuclei to induce the oxynitride glass to crystallize bulkly during heat-treatment.

在玻璃晶化处理时，首先在TiN微晶粒子的周围析出含有Ti、N成分的未知晶相，而后相继析出方石英和α-堇青石。

In this next to a stream, there is a small bluestone lying motionless next to a cluster of grass has been a year, and it bent to the sea life, it felt really colorful sea life, not only a variety of different kind of fish, some crabs, lobsters, starfish, etc., where the more lively than the stream.

在这条小溪的旁边，有一块小青石一动不动地躺在一丛小草旁已经有一年了，它一心想去大海里生活，它觉得大海里的生活真是丰富多彩，不但有各种各样的鱼儿，还有一些螃蟹，龙虾，海星等等，那里可比小溪热闹多了。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
