晶畴(crystal domains)指晶体结构中为界面所分隔的各个局部范畴。畴间的界面则称为畴界(domain boundary)。相邻晶畴间既有其结构上的某种一致性和连续性,但在某种特性上彼此间又表现出不一致性和不连续性。例如反相畴、磁畴(相邻畴中磁矩的取向不一致)等等。
聚合物材料多为半晶态,晶畴和非晶畴共存。
Polymers are usually semi-crystalline materials in which crystalline and amorphous domains coexist.
脱氢再复合后形成的微晶的磁畴结构则表明样品保留了铸态样品柱状晶的构型。
And for the samples after sufficient DR process, it isc onfirmed by the detected domain structures that the configuration of the column -like crystals retains.
单晶材料消除了晶界对畴壁移动的影响,具有很好的低场下的位移输出能力,这为微位移致动器的研制奠定了很好的基础。
These excellent single crystals, possessing a large displacement output under low magnetic field, build a foundation for the fabrication of the high precision micro-displacement actuators.
