Abstract: A method and a device for synchronous high-speed photographing of microparticle rotation in a liquid cyclone field and for determining the rotation velocity of a microparticle in a liquid cyclone field by using a combination of a synchronous high-speed photographing system and a transparent microparticle containing two centrosymmetrically arranged inner cores having the same diameter. The method comprises: using a transparent microparticle comprising two inner cores having the same diameter and arranged centrosymmetrically as a rotation test particle; acquiring synchronously two groups of two dimensional image series of microparticle motion in a liquid cyclone field using two orthogonally arranged high-speed digital cameras; and reconstructing a three dimensional motion trajectory of the microparticle from the two groups of synchronous image series, and determining a rotation velocity of the microparticle in the cyclone field at the same time.

Abstract: The present invention relates to a supported polymetal olefin polymerization catalyst, comprising a porous support, a magnesium-containing support component, a transition metal titanium component supported on the porous support, and further comprising at least one non-magnesium metal component supported on the porous support. Further provided is a preparation method and a use of the supported polymetal olefin polymerization catalyst. An efficient composite support supported polymetal Ziegler-Natta catalyst is provided in the present invention, wherein a porous support, a soluble magnesium compound, and a soluble non-magnesium metal compound are used as raw materials. The supporting of titanium is achieved while a composite support containing magnesium and non-magnesium metal components is formed in situ in the surface of the porous support. The present invention has the advantage of a simple preparation method, a low cost, a controllability of morphology, properties of the catalyst, etc. Comparing the provided catalyst with the same type of magnesium/titanium catalyst free of non-magnesium metal components, the catalytic performance such as polymerization activity, hydrogen regulation sensitivity and copolymerization performance are significantly improved.
