金属物质

In these regulations 'blasting process' means the cleaning, smoothing, roughening or removing of part of the surface of any substance or thing including granite, stone or brick by the use as an abrasive of a jet of sand, metal shot or grit or other material propelled by a blast of compressed air or steam or water or by a wheel.

在本规例中，&喷砂工序&指使用喷射砂粒、金属砂或粗砂或其他物料作为磨料，并以喷出压缩空气或水蒸汽或水或利用轮推动磨料的喷射，从而清洁、磨滑、磨粗或除去任何物质或物件(包括花岗岩、石块或砖块)的部分表面的工序。

In fact, the addition of fresh or immature organic material to soil is followed by its rapid decomposition with decrease in oxygen concentration and soil redox potential, which results in an increased mobility of reduced forms of some trace metals.

事实上，新鲜的和未成熟的有机物质在进入土壤中后，会随着氧浓度的降低和土壤氧化还原潜力的降低，而进行快速的降解。这一过程导致了某些痕量金属简化形式的移动性的增加。

Because it owns many excellent properties such as low density, higher hardness and red-hardness to carbide, chemical stability, good inoxidizability, less friction coefficient to steel, higher thermal expansion to carbide, and contains no or less resource-limited and expensive WC and Co, it is applied to industrial production to promote work efficiency and decreases the cost.

由于其具有密度低、硬度和红硬性高于硬质合金、化学稳定性和抗氧化性好、对钢的摩擦系数小、热膨胀系数高于硬质合金等性能特点，再加上其不含或少含资源有限、价格昂贵的WC、Co物质，应用于工业生产有利于提高工效、降低成本，因而国内外对Ti基金属陶瓷进行了大量的研究，同时其作为新型的刀具材料在金属切削领域内也得到了广泛地应用。

Fluid flow and component transport in fractured porous media are very important for understanding metallic ore formation,oil and gas migration,and transportation of pollutes and has attracted extensive investigations in recent two decades.

：断裂多孔介质中的流体流动和组分输运过程对于理解金属成矿过程、油气运移、污染物质的输运和分布十分重要，近 2 0年来得到了广泛的研究。

Let's sum up the experience of their ancestors in the global financial crisis was also reflected in one: When the stock, bond, agricultural products (15.93,-0.57,-3.45%, right), metals, energy Yixieqianli, but Gold or not the anti-up, and other things and then drop the more serious when the higher gold on the rise, although the "currency war" there are a lot of controversy, but the author also put forward a very troubling subject people - in the note before Gold has always been recognized as the world's hedge the last choice, after the collapse of national gold standard through a variety of monetary and material readiness to carry out risk reserves, and individuals can not repair a crude oil storage keep it?

让我们加快他们的祖先在全球金融危机的经验总结也反映在1：当股票，债券，（15.93，-0.57，-3.45％，农产品右），金属，能源Yixieqianli，但黄金或不反了，和其他的东西，然后下降，更严重时，社会上越来越高的黄金，虽然&货币战争&有许多争议，但作者还提出了一个非常令人不安的问题的人-前的说明黄金一直被公认为世界上的对冲后，国家黄金标准通过金钱和物质准备各种崩溃最后的选择，进行风险准备金，个人不能修复的原油储存保持下去吗？

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
