This paper is mainly to instruct some common bimetallic bearing material and combination technology.

本文主要介绍一些常用的双金属轴承材料以及双金属轴承材料与钢背的复合工艺。

"Bimetallic:Consisting of two metals, often bonded together and having different rates of thermal expansion."

双金属的：由两种通常是结合在一起且具有不同热膨胀系数的金属组成的。

A preliminary discussion on the possible synergic effect of bimetallic catalyst has also been made.

用IR和TEM技术对PVP负载型金属催化剂进行了表征，并讨论了双金属协同脱卤作用。

Now we set foot in bimetallic wires, cables and metal products,etc.

我们现已涉足双金属线缆，电缆及金属制品等。我们理解您远离中国。

Another founder of death/black metal.

这是另一个死亡金属/黑金属的创造者。

Meanwhile, the accurate mask alignment between the active layer on the bottom glass and the black matrix on the top glass and the choice of low-reflectivity black matrix material in conventional technology are also omitted.

并利用淀积欧姆接触层n〓a-Si：H和金属薄膜时沉积在SiN〓保护层上的n〓a-Si：H和金属薄膜作遮光黑层，省去了传统方法中上玻璃基板的黑矩阵与下玻璃基板TFT有源层沟道之间苛刻的对版工艺，并避免了传统黑矩阵制作工艺中对低反射率黑层材料的需求。

A hard brittle blue-gray or blue-black metallic element that is one of the platinum metals; the heaviest metal known.

一种硬而脆的蓝灰色或蓝黑色金属元素，铂系金属，已知最重的金属。

In this paper the fine performance and application prospects of boron and metal boride are introduced, and the methods and principles of preparing such material at home and abroad are outlined.

介绍了单质硼粉及金属硼化物的优良性能和应用前景，国内外制备和生产单质硼粉及金属硼化物的方法与原理。

By graduating the content of metal boride among several coating layers, the effect of differences in thermal expansion rates between carbon and metal boride are attenuated.

通过在几层覆层中金属硼化物含量的逐渐变化，使碳和金属硼化物之间热膨胀率差异的影响变小。

Species of metallic deposits are quite complicated: Besides commonly-seen pyrite ,chalcopyrite and bornite, there exist varied copper-bismuth sulfosalt minerals(sandber}erite, Bi-tennantite, Bi-tetrahedrite, aikinite, wittichenite),tungsten-tin sulfidesand polymetallic sulfides.

金属矿物种类复杂，除常见的黄铁矿、黄铜矿、斑铜矿外，还有多种铜铋硫盐矿物（锌砷黝铜矿、铋砷黝铜矿、铋锑黝铜矿、针硫铋铅矿、硫铋铜矿）、钨锡硫化物（硫铁锡铜矿、硫钨锡铜矿）及多金属硫化物。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
