变尖锐 meaning in Chinese
come to a point
sharpen
Examples
- The formation process of w - type ferrite underwent from oxide of metal , the m - type transition phase to final w - phase . when the heating rate was 5 / min , at 900 for 3 hrs and 1200 for 4 hrs , pure m - type and w - type ferrites were formed in air respectively . with heat treatment temperature increasing , crystal structure was more intact , the saturation magnetization increased and the coercive force decreased
热处理过程表明， m型铁氧体直接由金属氧化物反应形成，未经历尖晶石中间相； w型铁氧体形成由金属氧化物到m相过渡相最终向w相的转变；当升温速率为5 min ，温度在900 ，保温3小时和1200保温4小时，就分别形成单相m相和w相铁氧体；随着热处理温度的升高和保温时间的延长，衍射峰变尖锐，结晶更完整，空心微球的饱和磁化强度增大，矫顽力减小。
