轨道车轮踏面接触椭圆参数计算，最终获得椭圆面的长轴与短轴长度(Wheel tread contact with the track ellipse parameters calculated)

----------------------------------------------------- This file produces the output file test_impulse.wav containing an approximation to the unit impulse (delta) function. The value of alpha on [0,1] determines the bandlimit of the approximation. This method is used to avoid the technical difficulties in producing (and reproducing) an ideal impulse (delta) function in audio. This file also produces the .wav audio file test_audio.wav which is an audio test vector intended to be used in the impulse response inversion experiment. (4/24/2002) NOTE: Impulse is bandlimited to alpha*Fmax where Fmax = Fs/2, or the Nyquist frequency.
