有缺陷晶体
双语例句
- With the increase of sintered temperature, the barium ferrites prepared by coprecipitation-melted salt method come from imperfect crystal to perfect crystal, while the barium ferrites prepared by Sol-Gel method come from soft magnetic phases to permanent magnetic phases, and there are two phases in 800 ℃.
随焙烧温度的升高，采用共沉淀-熔盐法制备的样品逐步由非晶态向晶态转化，而溶胶-凝胶法制备的样品，由软磁相向永磁相转化，800℃时两相共存。 - Because it has long molecule, different molecular weight, and imperfect crystal structure, the temperature of melting is ranged, unlike the low molecular weight material, has a prominence peak.
这种相变材料，由于分子链较长、分子量是分布的，结晶又不完善，因此相变过程有一个熔融温度范围，而不像低分子量的物质有明显的熔融尖峰。
