Process capability indices have been widely used in the manufacturing industry,providing numerical measures on process precision,process accuracy,and process *** measures for processes with a single characteristic have been investigated ***,capability measures for processes with multiple characteristics are comparatively neglected. In this paper,inspired by the approach and model of process capability index investigated by *** et al.(2.03) and A.B. Yeh et al.(1998),a note model of multivariate process capability index based on non-conformity is *** for this index, the data of each single characteristic don’t require satisfying normal distribution,of which its computing is simple and particioners will not fell too *** last the application analysis is made.

According to the parameters of a Brown Big-eared bat＇s pinna,a simple obliquely truncated bat ear model that made by line and plane was designed,which was numerically simulated with finite element *** change of far-field directivity was analyzed in elevation and azimuth as the frequency *** results show that,compared with the pinna of the Brown big-eared bat,the present model has the advantages in wider bandwidth of frequency driven scanning,better directivity in azimuth and larger angle scales in elevation. In addition,a wireless positioning method based on single base station could be achieved by using a frequency driven scanning antenna.
