With the obtained model of the power spectrum, we have theoretically analyzed the contribution of all the amplitude noise, timing jitter and pulse width jitter to the total noise power spectrum. The simulated results show that while the product of pulse width and angular frequency is larger than 1, the pulse width jitter will contribute an amount of noise to the total noise power.

Most of the frequency（1455.99 ± 187.09 Hz to 3534.13 ± 301.53 Hz）of songs in Chinese bulbul are overlapped with environment noise（under 3000Hz）. In order to study the impact of urban noise on the song performances of Chinese bulbul, this study was carried out at Taichung urban areas focusing on the difference of dialects between different environment noise habitats（Shu Yi Area, Chung Hsing University, Taichung Metropolitan Park） from March to November 2007. In addition to the 3 study sites, I sampled another 6 sites （Fengle Park, Taichung Park, Botanical Garden, Art Boulevard, Ren De Village, Tong Lin Village）to find out the differences of songs frequency resulted from different environment noise habitats.

In order to establish the complete dynamic simulation model for the heat recovery steam generator and develop an advanced drum level controller, the methods of probability and time series were used to analyze the field data on drum level sloshing noise. The mean value of the drum level was removed and the field data was de-trended to get the true sloshing noise. Meantime, the AR model was set up for the drum level sloshing noise, and simulation results show that the model realizes matching simulation of the drum level noise signals in the power spectrum. The model can also match the drum level noise successfully in the time domain.
