    摘要: Polymerization process for preparing monodispersal organic/inorganic composite nano-microsphere in the field of nanometer technology is disclosed. The process comprises preparing two different miniemulsion systems of A with inorganic nanoparticles and B with polymerisable monomers in advance; adding water-soluble initiator into A, stirring till complete dissolution, then adding B to stir till mixing evenly;finally, heating the mixed system to a given temperature for isothermal reaction. The grain size of the superparamagnetic Fe 3 O 4 /polystyrene is homogeneous and controllable, and the magnetic particles content is controllable.

    摘要: An optical pulse compression reflectometer is provided, which comprises: a single wavelength continuous optical source, an optical splitter, a modulation frequency pulse generating module, an optical directional coupler, an optical fiber under test, an optical coupler, a balanced photodetecter, and a pulse compression processing module. The present invention, in addition to overcoming the contradictory constraint between spatial resolution and measurement range in traditional time domain reflectometry and giving to full play the super spatial resolution from frequency modulation technology, has a longer measurement range than that in the optical frequency domain reflectometry.
