1·Methods Scanning electron microscope and X-ray analysis were used to study the distribution of all kinds of elements in sand-cast, sculpt and clear-sand of one foundry work and quarry work.

用扫描电子显微镜和X射线能量色散仪测定某铸造作业翻砂车间、造型车间、清砂车间和某采石作业生产性粉尘粒子的结构及各元素的百分含量。

2·So you're wondering how to cast metal in sand.

所以，你想知道如何在砂铸造的金属。

3·Seen from above, the shadows cast onto the sand created shifting patterns like sundials.

从上面看，投在沙滩上的阴影创造了像日晷一般的移动模式。

4·According to different casting methods, divided into continuous cast iron pipe and the centrifugal cast iron pipe, wherein the centrifugal cast iron pipe is divided into two types of sand and metal.

按铸造方法不同，分为连续铸铁管和离心铸铁管，其中离心铸铁管又分为砂型和金属型两种。

5·The cast ingots prepared using sand mould and metal mould were analyzed to investigate the effect of cooling rates on morphologies and characters of M2C eutectic carbides in M2 high speed steel.

采用砂型和金属型铸造制备m 2高速钢铸锭，研究了冷却速度变化对高速钢m 2c共晶碳化物形态及性质的影响，探讨了M2C共晶碳化物形态变化的机理。

6·The fine surface quality and dimensional accuracy cast hot work die was obtained by special sand V method casting technique.

采用特种砂v法铸造工艺获得了良好表面精度和尺寸精度的铸造模具。

7·The coating sand for cast iron and cast steel and collapsible coating sand for nonferrous alloy casting are also described.

论述了普通铸钢、铸铁件用的覆膜砂、非铁合金铸件用的易溃散覆膜特种性能覆膜砂。
