size of crystal grain

The result shows that the size of crystal grain obtained by EMC in suitable technique can be refined.

结果表明：合适与匹配的连铸工艺和电磁场处理可使镁铸坯晶粒组织细化。

Another is that the hard phase and the soft phase both have microstructure with crystal grain of fine and homogeneous, and the size of crystal grain had better within magnitude of nanometer.

二是硬磁相和软磁相均要求有晶粒细小且分布均匀的显微结构特别是软磁相晶粒尺寸尽可能达到纳米尺寸。

This small earrings, such as soybean grain size, craftsmen are inlaid in the top of the 13 Crystal, closely combined in the elliptical disk alloy to become an organic whole.

这款小耳饰如黄豆粒大小，工艺师却在上面镶嵌了13颗水钻，紧密联合在椭圆的合金盘面上成为一个有机的整体。
