The results showed that the echolocation calls of the leaf-nosed bats were constant frequency-frequency modulation signals with 2-3 harmonics and the second one among these three harmonics was its dominant frequency. The constant frequency components of three harmonics (Mean±SD, n=18 ) were 33.3±0.2 kHz, 66.5±0.3 kHz, and 99.4±0.5 kHz, respectively. In examined FTCs of 72 IC neurons, their Q 10 -dB values ranged from 0.5 to 95.4 (9.2±14.6) and the neurons whose best frequency around the dominant frequency had sharp frequency tuning.

In this paper,the discharge capacity,stability voltage and the ratio of constant current charge capacity and battery discharge capacity of lithium ion battery were studied. For the lithium manganese lithium-ion batteries,the discharge capacity,mid-value voltage and stability voltage all increased with increasing charge cutoff voltage. As long as charge cutoff voltage was no less than 4.15 V,the battery discharge capacity loss would not exceed 6%. When charge cutoff voltage was 4.15V,the constant current charge capacity accounted for more than 85% of total charge capacity,a little change from 4.20 V.

According to the analysis and computational results in this thesis, although the actual structure and work conditions of the pressure vessel in nuclear power station are much more complex than that of the pressure vessel model, the program FEARPV still can get quite good convergence on the plasticity andcontact iteration. And also the program FEARPV has good value stability, and good regularity. During the heating, compression, constant temperature, constant pressure, cooling and decompression process, the regularity is basically in common with that of the pressure vessel model.
