Full widthhalf Maximum (FWHM) : the width of a curve (for example, the PSF) at half of it's peak value.
半最大值宽度:一条曲线(例如一条点扩展函数曲线)最大值的一半的宽度。

As metastable atoms deexcite, the vapor velocity and temperature increase, the peak value of the velocity distribution function shifts rightward, and the halfwidth increases.
亚稳态原子消激发,使蒸气宏观速度增加,温度增加,所以使速度分布函数峰值右移,半宽度增加。

Obvious error of peak value may appear if the signals with small full width at half-maximum (FWHM) were filtered with traditional smoothing and de-noising approaches.
