A high-speed and high-res ol ution optical A/D quantizer is proposed. Its architecture is discussed. Bit circ uits are built by using the phase modulators in pa
The photochemical isomerization of trans and cis-difluorostilbenes has been studied.In the presence of a photosensitizer (biacetyl, 0.05 mol·L~(-1)) about 75%
In structural chemistry,it has been well accepted that,besides orbital interactions,geo-metrical factors e.g.size and shape of the bonded atoms and groups,may
