摘要:
The present invention relates to a catalyst component and a catalyst for olefin polymerization. The catalyst component utilizes magnesium halide and silica as composite support, and the particle morphology thereof can be improved by regulating the ratio of magnesium halide to silica. Further, the purpose of stabilizing the rate of catalytic polymerization reaction and improving the particle morphology of polymer so as to meet the requirements on catalyst performance of various polymerization processes can be achieved through the combination of the supports of the catalyst. In the meantime, when used in the polymerization of propylene, the catalyst of the present invention exhibits a relatively high polymerization activity and high stereospecificity.

摘要:
A self-adjusting wrench having a handle and a jaw member rotationally attached thereto. A smoothly curved handle face opposes a planar face on the jaw member which adjusts for distance from the curved handle face by following a generally circular path around a pinned attachment of the jaw member to the handle. A spring or similar biasing device continuously urges the jaw member toward the handle thereby making the device self adjusting to the size of the object placed between the jaw member and the curved handle surface.

A method for calculating 19 biological parameters associated with the light absorption of human skin by means of a mathematical model. This method establishes a relevance between the skin spectrum and the biological parameters associated with light absorption in the epidermal/dermal layer of skin, by establishing two levels of analytical models, namely, a skin spectral analysis model and a mathematical model of biological parameters in the skin associated with the light absorption, achieves virtual spectrums which are stimulated by a set of skin parameters, and then performs optimization iteration by information processing technology using the virtual spectrums and the actual spectrums, to find a set of optimized results which meets a specific standard of the goodness of fit, thus reaching the goal of quantitatively analyzing biological parameters associated with the light absorption in human skin.

摘要:
The present invention provides a chair assembly having a support member defining a plurality of positioning stations separated by a predetermined vertical distance. A coupling element may be included that defines a first portion and a second portion, such that the first and second portions are pivotably coupled to one another. The coupling element may be engageable with one or more of the positioning stations of the support member. A foot ring may also be included, where the foot ring is engageable with the coupling element to be positioned at a desired height while being securely affixed to the coupling element and thus, the support member of the chair assembly.
