METHODS: Pharyngo nasoparyngeal swab specimen were collected from 220 healthy children in two kindergartens in Guangzhou city. The swab was spread on the blood disk, cultured at 35℃, 5% CO2 for 24 h and identified by Optochin paper. The minimal inhibitory concentration of penicillin was measured by the agar dilution method. The positive rates of bacteria carrier were compared by using chi square test.

The ANNs models of the periodic defected ground structures and a novel combinatorial nonperiodic defected ground structures with the characteristic of double stop band have been developed in this paper. The structure sizes of DGS and the frequencies are defined as the input samples of ANNs, the parameters of transmission coefficient calculated by FDTD method are sampled and defined as the output samples. For the PDGS with biggish structure sizes the transmission coefficients have the tiny dither owing to abnormal disturbance and the training samples have been smoothed by the least square method and five-spot triple smoothing method.
