Two approaches called virtual moving-cyclic autocorrelation(VM-CAC) and virtual moving-cyclic crosscorrelation(VM-CCC) based on conjugate cyclic multiple signal classification(MUSIC) is proposed for a uniform linear array.

According to the author,the "XIANG+NP"can be divided into two types: the factive motions and the fictive motions.

Leonard Talmy, in her book Toward a Cognitive Semantics(2000), defined the cognitive pattern of veridically unequal discrepant representations of the same object as "the pattern of general fictivity", and based on this, introduced the cognitive concept of "fictive motion", comparing to "factive motion".

The paper built up the virtual platform of the vibration isolation system of diesel engine and carried out modal analysis of the system,simulated the instance of horizontal swayed situation accord- ing to GJB standard,and analyzed the response of the system under the shock.

The EWB virtual platform is a sort of software used specially in the design and emulation of electric circuit.

According to the common problems existing in the design process of embedded system such as lack of support for systemic simulation, less methods for hardware description, inferior transplantable of simulation system, an embedded system virtual platform based on flexible bus was proposed and implemented.
