    Broad absorption lines, present in $\sim$ 10\% of quasars, are among
    the least understood phenomena observed in AGN.The matter responsible
    for these lines is highly ionized, and flows outward at large velocit
    ies with respect to the central engine, but the origin of its ionizat
    ion and velocity is still an enigma.  We propose ASCA observations of
    2 X-ray bright BAL quasars, expecting that the resulting spectra will
    allow further understanding of the location, kinematics, and density
    of the absorbing matter.  The proposed observations will explore the
    unique spectral capabilities of ASCA, as,for the first time,we expect
    to detect and measure Doppler-broadened resonance absorption lines in
    addition to absorption edges due to the absorbing matter.
