  • Recovery Experiment of Psammophytes in Minqin County by Multi-Functional High Polymer Reagent
    Journal of Desert Research, 2006
    Co-Authors: Zhang Song-lin, Tian Xia, Zhao Shou-cai, Dong Qing-shi, Zhang Jin-chun
    Abstract:

    The study area is located in the adjacent region of the Minqin Oasis in Gansu Province with the Tengger Desert and the Badain Jaran Desert.A multi-functional High Polymer reagent was used to recover the degenerative psammophytes by the supplement of drip irrigation.As a result,the 0~230 cm layer average moisture contents under the Nitraria angutorum and the Haloxylon ammodendron were Higher than those of the control ones,especially that under the Nitraria tangutorum was the Highest.Besides,the average dry weight of the single tip,the average length of the largest new tip,the average length of the smallest new tip,and the average diameter of the biggest new stalk of the Haloxylon ammodendron in the drip irrigation experiment were much Higher than those of the control ones,respectively.The main growth changes of the Nitraria angutorum are shown in the height,stalk,and cap in the drip irrigation experiment.It is obvious that this reagent not only kept Higher moisture in soil under the psammophytes,but also promoted the growth of plants and recovered the degenerative vegetation cover.

  • Fixation of Moving Dune by Multi-Functional High Polymer Reagent
    Journal of Desert Research, 2005
    Co-Authors: Zhang Jin-chun
    Abstract:

    The study area is located at the edge of the Minqin Oasis in Gansu Province, neighboring to the Tenger Desert and the Badain Jaran Desert. The multi-functional High Polymer reagent was used to fix the moving dunes of this area in experiment. As a result, comparing to the control one, the thickness of soil crust at the same position in the weeded experimental area and the unweeded experimental area increased 81.25% and 32.25%, respectively. The dune with crust was more resistant to wind erosion than that of the control one. Besides, the average moisture content of the soil layer between 0~80 cm in the unweeded experimental area was 76.27% Higher than that of the control one. This experiment proved that this kind of reagent is not only effective in fixing dunes, but also has effect in increasing the moisture content of sand layer.

  • MICRORHEOLOGY OF High-Polymer SOLUTIONS
    Journal of Polymer Science Part B: Polymer Physics, 1991
    Co-Authors: J. P. Montfort, André Tonck, Jean-luc Loubet, J. M. Georges
    Abstract:

    A new surface force apparatus is used for investigating the viscoelastic properties of High-Polymer solutions or Polymer melts confined between two solid surfaces. We describe the experimental setup and discuss how to obtain the rheological behavior of the liquid from the transfer function given by two capacitance displacement transducers. In particular, we point out that for a distance between the surfaces enclosing a thin film below some thousands of Angstroms, the elastic deformation of the solids is no longer negligible. Experiments conducted on a semidilute solution of polybutadiene show the applicability of the device for study of the dynamic properties of thin-film Polymers.

  • Development of conducting High Polymer probe
    Synthetic Metals, 2001
    Co-Authors: Y. Itagaki, M. Satoh
    Abstract:

    This paper presents a novel conductive High Polymer probe for the testing of High-density printed wiring boards. For this application, technologies for producing fine probes with low resistances are developed. We combined photosensitive acrylate and pyrrole, which upon oxidization and development produced conductive polypyrrole probe. By this method, probes of 60 pm x 60 μm x 100 μm by 120 μm spacing and resistances of less than 10 kΩ were successfully produced.
