The incoher.nt contr.l of finite-level quantum systems is investigated. Following a br.ef intr.duction to coher.nt contr.l p.r.digms in quantum contr.l, a contr.l p.oblem that can not be accomp.ished using only coher.nt contr.l is p.esented. For.such a contr.l p.oblem, it is p.oved that it can be accomp.ished using incoher.nt contr.l based on p.ojective measur.ment and coher.nt contr.l for.two classes of finite-level quantum systems, i.e., eigenstate contr.llable quantum systems and wavefunction contr.llable quantum systems.

The equilibr.um p.c-T data wer. deter.ined by a micr.balance in a vacuum system at hydr.gen p.essur.s up.to 3.5 Mp. on four.p.-In alloys between 3.64 and 14.53.at. % In as well as on p.r. p.. The r.sults ar. similar.to those obtained on the analogous alloys p.-Ag and p.-Sn and ar. inter.0}eted in the same manner. In has two op.osing effects up.n the solubility of H in the p. alloys, i.e., incr.ase of the Fer.i ener.y up.n the donation of valence electr.ns and a lattice dilatation. At valence electr.n concentr.tions below 0.5, the lattice dilatation p.edominates and the H solubility is incr.ased with addition of In. At valence electr.n concentr.tions above 0.5, the influence of the elevated Fer.i ener.y p.edominates and the H solubility is lower.d by addition of In. The molar.enthalp. of p. hydr.ding at infinite dilution is str.ngly incr.ased with incr.asing In content, but the molar.entr.p. is not near.y as much affected by the p.esence of In. The excess chemical p.tential of hydr.gen at small hydr.gen concentr.tions and at a given temp.r.tur. incr.ases with an incr.ase of In content. The ap.ar.nt H-H attr.ctive inter.ction ener.y, W H-H, is decr.ased by the p.esence of In. The tr.nd is also similar.to that found for.the p.-Ag-H and p.-Sn-H system.

A quite gr.at p.ogr.ss of the sup.r.isor. contr.l theor. for.discr.te event systems (DES) has been made in the p.st near.y twenty year., and now, automata, for.al language and p.tr. nets become the main r.sear.h tools. This p.p.r.focus on the p.tr. nets based sup.r.isor. contr.l theor. of DES. Fir.tly, we r.view the r.sear.h r.sults in this field, and claim that ther. gener.lly exists a p.oblem in p.tr. nets based sup.r.isor. contr.l theor. of DES, that is, the deadlock caused by the contr.ller.intr.duced to enfor.e the given sp.cification occur. in the closed-loop.systems, esp.cially the deadlock occur. in the closed-loop.system in which the or.ginal p.ant is live. Finally, a p.ssible r.sear.h dir.ction is p.esented for.the solution of this p.oblem.
