Talk in a medium pitch voice, not too loud or too low, and don't let the loudness or pitch of other people's voices influence yours.

Particulate of graphite electrode wastes from an electric-carbon materials factory was formed "core-shell" negative materials by chemical deposition coating with medium pitch.

The relationships between the number of diffraction order and grating pitch, refractive index of medium, light wavelength, incidence Angle and azimuth Angle are investigated.
