11.Based on spatial correlation theory, by means of Monte Carlo simulation and Equivalent Normal Deviate, an area probability model for weather conditions, the Boehm Sawtooth Wave(BSW) model, has been developed.
12.The ac currents applied can be a sine alternative current with a relevant frequency, or a pulsed current with a suitable pulsed width rand or a discontinuous pulsed current whose width r is very shorter than the intervals between pulses, and or a " sawtooth" pulsed current with the time of ramp phase of the sawtooth is very much shorter than the sawtooth descending time, the ratio of them can be<10-3. The physical model of the ac current drive is analyzed in detail.
13.In this paper,on the basis of probability model of weather conditions occupying an area-the Boehm sawtooth wave(BSW)model,by means of least-square procedure,the results were fitted in graphical form that imaged the character of the probability distributions of weather elements.
14.Sine and square waveforms are generated with AD9851. An arbitrary waveforms generator which can generate the triangle waveform, sawtooth waveform, FM, PM, AM, burst waveform and other waveforms is designed with FPGA. Arbitrary waveforms can be downloaded to the arbitrary waveforms generator via serial port of PC.
