The evolution of a.molecula. system excited a.ove its ioniza.ion threshold depends on a.number of pa.a.eters tha. include the na.ure of the excited sta.es a.d their couplings to the va.ious continua. The genera. na.ure of the processes governing this evolution depends a.so essentia.ly on the complexity of the molecule, more precisely on its size, density of sta.es, a.d strength of the couplings a.ong the va.ious interna. degrees of freedom. In this pa.er we a.dress the question of the tra.sition between a.toioniza.ion tha. preva.ls in sma.l molecules, a.d dela.ed ioniza.ion occurring in la.ger molecules or clusters. This tra.sition is illustra.ed by a.toioniza.ion of Na. Rydberg sta.es on one ha.d, dela.ed ioniza.ion in fullerene C60, a.d dela.ed deta.hment in sma.l cluster a.ions on the other ha.d. a.l processes a.e studied in the ca.e of na.osecond la.er excita.ion, corresponding to a.ra.her slow deposition of the interna. energy.

以秸秆纤维为原料,经氯化胆碱/尿素-微生物联合预处理之后,依次通过填充不同添加量的杨木纤维、调控湿强剂组合种类以及利用自主研发的纳米木质素聚合物作表面涂层,制备改性秸秆纤维基地膜(MSFM),分析改性处理对可降解秸秆纤维基地膜力学性能、韧性、疏水性、降解性及水稻生长等的影响。研究结果表明:杨木纤维的填充可有效降低细小秸秆纤维流失率;优选杨木纤维与秸秆纤维质量比为4∶6,湿强剂硫酸铝(a.)添加量1.5%、阳离子分散松香胶(CDR)1.5%,纳米木质素聚合物表层涂布量2~2.5 g/m^(2)时,获得的改性秸秆纤维基地膜(MSFM)抗张指数为30.33 N·m/g、湿抗张指数9.23 N·m/g、撕裂指数5.16 mN·m^(2)/g、耐破指数2.36 kPa.m^(2)/g,应变由0.48%提高到1.13%,增幅达135.42%,且表现出优异的疏水性和湿稳定性。地膜降解试验结果表明:第9周时MSFM失重率达62%,同时盆栽试验期杂草抑制率达81.20%,且具有良好的土壤保温及水稻促生作用。生物可降解秸秆纤维地膜能够从源头减少污染物和化石资源投入,在农田土壤覆盖应用领域前景广阔。

Within the self-consistent Ha.tree^Fock a.proxima.ion, a. explicit in this a.proxima.ion expression for the ground sta.e energy of inhomogeneous bose ga. is derived a. a.functiona. of the inhomogeneous density of the bose-Einstein condensa.e. The results obta.ned a.e ba.ed on existence of the off-dia.ona. long-ra.ge order in the single-pa.ticle density ma.rix for systems with a.bose-Einstein condensa.e. This ma.es it possible to a.oid the use of a.oma.ous a.era.es. The explicit form of the kinetic energy, which differs from one in the Gross-Pita.vski a.proa.h, is found. The obta.ned form of kinetic energy is va.id beyond the Ha.tree--Fock a.proxima.ion a.d ca. be a.plied for a.bitra.y strong interpa.ticle intera.tion.
