青铜

In this thesis, we contrastively studied the transport properties of series of pure or doped potassium blue bronzes and three kinds of purple bronzes, respectively. Our investigation may help to explore the CDW dynamical mechanism.

在本论文中，我们通过对系列掺杂蓝青铜样品及不同紫青铜样品的输运特性进行实验对比研究，尝试进一步揭示电荷密度波输运动力学以及杂质缺陷对其影响的微观实质。

Since "Apollo " was discovered during the Renaissance, it was highly respected by the people of that time. Cellini's small copy recalls the pride and the beauty of this sun-god.

自从文艺复兴时期发掘出《眺望楼的阿波罗》以来，这尊雕塑一直深受人们的景仰，切利尼的小型青铜复制品重现了太阳神的美丽与高傲，而青铜的质地类似于健康的肤色，十分贴近古希腊人的审美理想。

The dispersoid distribution of the second phase could strengthen the surface of the alloy, which decreased the quantity of abrasive particles. The wear volume of the alloy was decreased. The hardness and strength of the alloy were increased after ECAE. The resistance of deformation was improved and the depth and width of furrows were decreased due to the increase of hardness and strength. As a result, the wear-resistance and tribological properties of the alloy were improved after ECAE.

ECAE热挤压处理显著细化了铝青铜合金的微观组织，弥散分布的第二相对合金起到强化作用，减少了剥落磨粒的数量，降低了合金的磨损量；ECAE热挤压处理的铝青铜合金组织细小，强度和硬度高，提高了合金抵抗塑性变形能力，减轻了磨粒对合金表面的犁削作用，提高了合金的摩擦磨损性能。

The compound catalyst is added with a cocatalyst ingredient, hydrogen tungsten gunmetal or hydrogen molybdenum gunmetal on the basis of a normal carbon platinum-carried compound catalyst.

该催化剂在一般碳载铂催化剂的基础上添加了助催化成分氢钨青铜或氢钼青铜。

Grinding wheel is usually mounted on surface grinding machine, external circular grinding machine and internal circular grinding machine, and can also be mounted on grinding wheel machine, knife grinder and universal cutter grinder for grinding of cutting tool. According to different functions, grinding mode and type of grinding machine, grinding wheel is manufactured into ones with all kinds of shapes and sizes, and common grinding wheel includes plane grinding wheel, cylinder grinding wheel, double hypotenuse grinding wheel, cup grinding wheel, flaring cup wheel, disc wheel, centerless grinding wheel, etc. The types of products include external circular, plane and centerless grinding wheels used for f

公司的产品类型有用于钨钢硬质合金的精粗磨削加工的外圆磨、平面磨、无心磨砂轮；有用于陶瓷、氧化锆白陶瓷、黑陶瓷行业的CBN/SDC金刚石平形砂轮、精密切割片、平行加强形砂轮和开槽电镀磨头；用于钢化玻璃，灯饰玻璃，水晶玻璃，磁性材料行业的CBN/SDC金刚石精密切割片，青铜磨盘，青铜切割片，平行双粒度磨盘和小磨头，深加工行业的CBN电镀和烧结磨轮、抛光磨盘；用于高速钢，45#钢的剪刀、锯片、刀片的精粗加工，用于加工硅片材料、铁氧体及其他材料的金刚石工具；以及其他行业需要的各种要求的非标金刚石工具。

Correspondingly, in the Yangtze valley, many evidences had shown the region around some great larks along middle and lower course of the river is the home of rice, ramie, lotus, water-caltrop, bamboo, plum and lacquer tree, in which the rice and bamboo are typical crops of China.

特别值得一提的是四川广汉的青铜器物与中原的类型有很大的差别；另外江西新干出土的不少商代铜器农具显示当时江南的青铜冶炼技术水平更高，产量更多。

During the Chinese Bronze Age, the metal was used for the weapons the aristocracy needed for its occupations of hunting and war, but despite its superior efficiency, bronze was less often devoted to common tools such as agricultural implements, which were usually made of the traditional Neolithic materials of stone, bone, and wood until the introduction of iron.

当时的贵族用青铜来制造打猎和打仗用的兵器，然而尽管青铜是如此优越耐用，它却很少被用於铸造如农具般的普通工具。在铁铸工具出现以前，农具通常都以石，骨和木这些传统的新石器时代物料制成。

Up to now,however,in the family of moly b-denum bronzes the investigations mainly focus on the blue bronze.

然而到目前为止，在钼青铜中对电子结构的研究主要集中在蓝青铜上。

Through analysis of heat penetration depth and thermal conductivity between stainless steel and phosphor bronze, the result shows that stainless steel screens have better refrigeration performance than phosphor bronze ones.

通过对不锈钢和磷青铜丝网材料热渗透深度和热导率的分析，指出在这一温区采用不锈钢丝网的制冷性能优于磷青铜丝网。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
