2) state simulation of frequency region
频域模态
1.
Enlightened by the theory that the critical speed at different stage of the rotoring system with small radius ratio has a tendency to approach to the inherent frequency (low stage) of transverse vibration,the inherentfrequency of domestic speedy cotton spindle D5214 is tested with the method of state simulation of frequency region, proving that the spindle D5214 is excellent in dynamic property.
根据径长比值较小的转轴系统各阶临界转速接近横向振动各阶固有频率(低阶时)特性,用频域模态法测定了国产高速棉纺锭子D5214E的固有频率,证明D5214E锭子具有优良的动态特性。
3) time domain modal analysis
时域模态
1.
In the paper the main time domain modal analysis methods are summarized,the important points for developing and application of time domain modal analysis software are pointed out and the analysis results of time domain and frequency domain in an example are compared.
时域模态分析方法是当前国内外热门的课题。
4) complex mode method in time domain
复模态时域法
1.
Earthquake action calculation of structure-soil interaction system——according to complex mode method in time domain based on the earthquake model about seismic code;
结构-土相互作用体系的地震作用取值——基于规范地震动模型的复模态时域法
5) modal recovery region
模态恢复区域
补充资料：局域态（localizestate）
局域态（localizestate）
固体材料中与特定位置相关，具有特定能量的电子态。当一个电子占据此状态时，它被束缚于具有特定能量的特定位置附近。无序固体中由于周期性被破坏，将产生带尾局域态。材料中的缺陷态或施主、受主杂质上的电子态，或强掺杂半导体中的带尾态也都是局域态。存在局域态是无序的标志。局域态电子的迁移必须通过跳跃（hopping）发生。
