As shown in Fig. 4.2, grain flow is the direction of the pattern that the crystals take during plastic deformation.

如图4.2所示，晶粒流动的方向就是在塑性变形期间结晶排列的方向。

In this widely used technique, x-rays are directed through crystals of a protein, and its structure deduced from the pattern of diffraction of the beam.

利用这项广泛应用的技术，X射线直接从一个蛋白穿过，它的结构可以通过光束的衍射类型推断出来。

Crystals are the result of molecules arranging themselves in a regular pattern extending in all three dimensions.

The result was a pattern of spots that shows that the lens-like crystals do indeed behave as lenses.

Nowadays AMSC starts by engraving a microscopic pattern onto a sheet of nickel-based metal, to align the crystals.
