1. Study on chromatic aberration in a population of Chinese myopic eyes by means of optical design.

    Biomedical Optics Express 4(5):667 (2013) PMID 23667784 PMCID PMC3646595

    Two kinds of individual eye models, involving and without involving the angle between visual axis and optical axis, are established by means of optical design. We use them to study the properties of the transverse chromatic aberration (TCA) and longitudinal chromatic aberration (LCA) over the vi...
  2. Aspheric spectacles for correcting presbyopia with myopia and astigmatism.

    Applied Optics 51(29):6926 (2012) PMID 23052068

    The aim of this paper is to propose a method for designing aspheric spectacles capable of realizing good optical performance at both far and near vision for presbyopia. We have experimentally measured wavefront aberrations and axial lengths for eight myopic eyes. In consideration of the field of...
  3. The earliest normal flower from Liaoning Province, China.

    Journal of Integrative Plant Biology 51(8):800 (2009) PMID 19686377

    The early evolution of angiosperms has been a focus of intensive research for more than a century. The Yixian Formation in western Liaoning yields one of the earliest angiosperm macrofloras. Despite multitudes of angiosperm fossils uncovered, including Archaefructus and Sinocarpus, no bona fide ...
  4. Taxonomic investigations on permineralized conifer woods from the Late Paleozoic Angaran deposits of northeastern Inner Mongolia, China and their palaeoclimatic significance

    Review of Palaeobotany and Palynology 144(3-4):261 (2007)

    A diverse fossil conifer wood assemblage was described from the Late Paleozoic Angaran deposits in Inner Mongolia (=Nei Mongol) of northeastern China. The fossil wood materials were collected from the Upper Carboniferous Baoligemiao Formation in Sunitezuo Qi and the Middle Permian Zhes...
  5. Taxonomic investigations on permineralized conifer woods from the Late Paleozoic Angaran deposits of northeastern Inner Mongolia, China and their palaeoclimatic significance

    Review of Palaeobotany and Palynology 144(3):261 (2007)

    A diverse fossil conifer wood assemblage was described from the Late Paleozoic Angaran deposits in Inner Mongolia (=Nei Mongol) of northeastern China. The fossil wood materials were collected from the Upper Carboniferous Baoligemiao Formation in Sunitezuo Qi and the Middle Permian Zhesi For...
  6. Morphology and age ofYimaia(Ginkgoales) from Daohugou Village, Ningcheng, Inner Mongolia, China

    Cretaceous Research 28(2):348 (2007)

    New ginkgoalean ovulate organs of Yimaia type were found in the fossil-bearing bed of the village of Daohugou, Ningcheng, Inner Mongolia. They generally resemble other species of Yimaia and some detached seeds described under the morphogeneric name Allicospermum from th...
  7. A new MesozoicGinkgofrom western Liaoning, China and its evolutionary significance

    Review of Palaeobotany and Palynology 131(1):91 (2004)

    Well-preserved Ginkgo ovulate organs and associated leaves are described from the fossil-bearing Yixian Formation of the Late Jurassic or Early Cretaceous in Liaoning Province, China. The ovulate organs bear a cluster of (up to 6) ovules at the apex of peduncle. The ovules are seated...
  8. The missing link in Ginkgo evolution.

    Nature 423(6942):821 (2003) PMID 12815417

  9. Archaefructaceae, a new basal angiosperm family.

    Science 296(5569):899 (2002) PMID 11988572

    Archaefructaceae is proposed as a new basal angiosperm family of herbaceous aquatic plants. This family consists of the fossils Archaefructus liaoningensis and A. sinensis sp. nov. Complete plants from roots to fertile shoots are known. Their age is a minimum of 124.6 million years from the Yixi...
