综合考虑取向因子对纤维结构性能因素的影响，认为PAN原丝晶区取向因子约为0.9、总取向因子约为0.8时，纤维力学性能较好。
It was considered that the mechanical properties of PAN precursor was better when the orientation degree in crystalline region and overall orientation factor were about 0. 9 and 0.8, respectively.
采用含有丰富谐波分量的窄脉冲电流作为励磁信号对非晶丝直接励磁，使传感器具有灵敏度高、响应快的优点。
The magnetic sensor has characteristics of high sensitivity and quick response due to the amorphous wires excited directly by sharp pulse train current containing amount of harmonic signals.
另外，随着热丝与衬底间距的增大，沉积出的多晶硅薄膜样品的晶化率明显减小，薄膜的晶粒尺寸也相应减小。
In addition, with the increasing distance between the filament and the substrate, the crystalline volume fraction and the grain size of poly-Si films notablely decrease.
