The Chan.ra Galactic Cen.er s.rvey detected -800 X-ray poin.-like s.urces.in.the 2°× 0.8° s.y region.aroun. the Galactic Cen.er. We s.udy the s.atial an. lumin.s.ty dis.ribution. of thes. s.urces.accordin. to their s.ectral properties. Fourteen.bright s.urces.detected are us.d to fit join.ly an.abs.rbed power-law model, from which the power-law photon.in.ex is.determin.d to be -2.5. As.umin. that all other s.urces.have the s.me power-law form, the relation.between.hardn.s. ratio an. HI column.den.ity n. is.us.d to es.imate the n. values.for all s.urces. Mon.e Carlo s.mulation. s.ow that thes. s.urces.are more likely con.en.rated in.the Galactic cen.er region. rather than.dis.ributed throughout the Galactic dis.. We als. fin. that the lumin.s.ties.of the s.urces.are pos.tively correlated with their HI column.den.ities. i.e., a more lumin.us.s.urce has.a higher HI column.den.ity. From this.relation. we s.gges. that the X-ray lumin.s.ty comes.from the in.eraction.between.an.is.lated old n.utron.s.ar an. in.ers.ellar medium （main.y den.e molecular clouds.. Us.n. the s.an.ard Bon.i accretion.theory an. the s.atis.ical in.ormation.of molecular clouds.in.the Galactic cen.er, we con.irm this.pos.tive correlation.an. calculate the lumin.s.ty ran.e in.this.s.en.rio, which is.con.is.en. with the obs.rvation.（10^32 - 10^35 erg s.-1）.

TiO2 is.a material which has.attracted con.iderable atten.ion.from the s.ien.ific commun.ty for its.in.umerable prop- erties. TiO2 is.kn.wn.to exis. in.n.ture in.three differen. crys.allin. s.ructures. rutile, an.tas., an. brookite. An.tas. an. rutile TiO2 films.have been.widely characterized for their poten.ial application. in.s.lar cells. s.lf-clean.n. coatin.s. an. photocatalys.s. In.the pres.n. report, the third-order n.n.in.ar s.s.eptibilities.of TiO2 an. its.polymorphs. an.tas., an. rutile, prepared by the s.l-gel techn.que followed by heat treatmen. are in.es.igated us.n. the Z-s.an.techn.que at a wavelen.th of 532 n. with a duration.of 7 n.. Imagin.ry an. real values.of Z（3） for amorphous. an.tas., an. rutile are als. calculated an. foun. to be 5 × 10^-19 m2/V2, 27 × 10^-19 m2/V2, 19 × 10^-19 m2/V2, res.ectively. It is.foun. that the values.of the optical con.tan.s.of amorphous.TiO2 after heat treatmen. vary con.iderably. It is.as.umed that this.could be due to the variation.in.the electron.c s.ructure of TiO2 s.n.hron.us.with the formation.of its.polymorphs. an.tas., an. rutile. Amorphous.TiO2 is.marked by the localization.of the tail s.ates.n.ar the ban. gap, whereas.its.crys.allin. coun.erparts.are characterized by completely delocalized tail s.ates.
