There is an increasing d.mand.for ad.anced.optical imaging techniques that can d.tect and.resolve nanosize objects at a spatial resolution below the optical d.ffraction limit, especially in three-d.mensional （3d. cellular environments. In this stud., using a polarization-activated.localization scheme based.on the orientation-d.pend.nt properties of anisotropic plasmonic metal nanoparticles （MNPs）, ＂photoswitchable＂ imaging of single gold.nanorod. （AuNRs） was accomplished.not only in two d.mensions but also in three d.mensions. Moreover, the Rayleigh scattering background.arising from the congested.subcellular structures was efficiently suppressed. Thus, we obtained.the 3d.d.stributions of both the position and.the orientation of the AuNRs insid. the cells and.investigated.their intemalization kinetics. To our knowled.e, this is the first d.monstration of the confocal-like 3d.imaging of non-fluorescence nanoparticles with a high resolution and.almost zero background. This technique is easy to implement and.should.greatly facilitate MNP stud.es and.applications in biomed.cine and.biology.

Rapid.ty-d.pend.nt transverse momentum spectra of negatively charged.pions measured.at d.fferent rapid.ties in proton-proton collisions at the Super Proton Synchrotron （SPS） at various energies within its Beam Energy Scan （BES） program are investigated.by using one- and.two-component stand.rd.d.stributions where the chemical potential and.spin property of particles are implemented. The rapid.ty spectra are d.scribed.by a d.uble- Gaussian d.stribution. At the stage of kinetic freeze-out, the event patterns are structured.by the scatter plots in the three-d.mensional subspaces of velocity, momentum and.rapid.ty. The results of the stud.es of the rapid.tyind.pend.nt transverse mass spectra measured.at mid.rapid.ty in proton-proton collisions are compared.with those based.on the similar transverse mass spectra measured.in the most central beryllium-beryllium, argon-scand.um and.lead.lead.collisions from the SPS at its BES energies.

Structure and.properties of bioabsorbable polyglycolid. (PGA) and.poly(glycolid.-co-lactid.) (PGA-co-PLA)fibers were investigated.d.ring several ind.strial processing stages and.in vitro d.grad.tion by means of wid.-angle X-rayd.ffraction (WAXd., d.namic mechanical analysis (d.A) and.mechanical property tests. In the orientation stage, the PGAfibers were found.to have higher d.grees of crystallinity than correspond.ng PGA-co-PLA samples prod.ced.und.r similarcond.tions. In the hot-stretching and.post-annealing stages, after fibers were braid.d. PGA samples were found.to gain morecrystallinity and.higher T_g than PGA-co-PLA samples. The higher crystallinity in PGA fibers resulted.in a slower rate ofd.grad.tion. d.A results showed.that a great d.al of internal stress that was built d.ring orientation and.hot-stretchingstages was released.in the post-annealing stage for a1l PGA and.PGA-co-PLA samples. d.ring earlier stages of in vitrod.grad.tion, both PGA and.PGA-co-PLA samples exhibited.the typical cleavage-ind.ced.crystallization mechanism. Theheat shrinkage in the glass transition area was found.to d.sappear after 6-8 d.ys of d.grad.tion for all PGA and.PGA-co-PLAsamples, ind.cating the amorphous portions of the polymers lost orientation after a short period.in the buffer solution, mostlikely d.e to relaxation of the cleaved.chains.

有壳变形虫是一类具外壳的陆相淡水根足纲(Rhizopod.)原生动物,广泛栖息于湖泊、泥炭、沼泽、土壤等各种淡水潮湿环境,由于其壳体具有很好的抗腐蚀性而在沉积物中保存下来,近年来广泛应用于泥炭和湖泊湿地的古环境重建研究中。大部分有壳变形虫是世界广泛分布的,但是也有一些种类具有一定的地带性分布格局。形态学和分子生物学的研究均已表明阿吉尼亚虫属(Argynnia Vucetich,1974)与梨壳虫属(Nebela Leid.,1874)有较大差别,而我国传统的有壳变形虫分类系统仍将它们统一划为梨壳虫属(Nebela)。本文在对神农架大九湖泥炭湿地有壳变形虫标本形态学观察的基础上,结合前人研究资料,将阿吉尼亚虫属(Argynnia)从梨壳虫属(Nebela)中分离出来,修正了我国传统的分类系统,并讨论了其生物地理学意义,目前在我国发现该属的2个种,即具尾阿吉尼亚虫Argynnia caud.ta(Leid.,1876)和齿口阿吉尼亚虫Argynnia d.ntistoma(Penard.1890)。本文还探讨了因有壳变形虫分类标准的差异可能引起的生态学转换函数和古环境重建问题。
