| 3. | In the fabrication of diffractive optics elements and semiconductor , it is demonstrated that an initial edger can expand into smooth curves and the surface motion in different local place is not identical 在制作衍射光学元件以及半导体加工的刻蚀工艺中,刻蚀产生的表面面形随刻蚀时间的延长而产生动态的形变。 |
| 4. | The notable torsion effects of the surface ground motion above the alluvial valley are illustrated and the torsion effects become stronger as the frequency of the incidence is higher .
