Abstract: The present application belongs to a technical field of modifying natural polymer materials, provides a high-viscosity lithium carboxymethyl cellulose and preparation method therefor and application thereof. Raw materials are fed into a reactor, and the high-viscosity lithium carboxymethyl cellulose is prepared through an alkalization reaction, an etherification reaction, an acidification reaction and a substitution reaction. The prepared high-viscosity lithium carboxymethyl cellulose can be used for preparing a negative electrode plate of a lithium-ion battery. Compared with the existing lithium carboxymethyl cellulose, the high-viscosity lithium carboxymethyl cellulose provided by the present application can not only reduce an application amount in preparing a negative electrode plate of a lithium-ion battery so as to save a using cost, but also promote an electrochemical performance of the material in combination with a sodium lignin sulfonate.

Abstract: The present invention provides for methods for identifying modulators of extracellular matrix (ECM) movement towards a site requiring deposition of ECM. Such modulators can be applied for use in a method for the modulation of ECM movement towards a site requiring deposition of ECM, e.g. a wound, thereby allowing treatment of a condition involving ECM deposition. Since the modulator may either be an inhibitor or promoter, either excessive or insufficient ECM deposition could be dealt with by the means and methods of the present invention.

Abstract: A nonlinear resonance model-based active filtering crane steel rope resonance elimination control method, including: constructing a two-dimensional dynamic model of a bridge crane according to a Lagrange's equation; constructing a steel wire rope-motor nonlinear resonance model to detect a harmonic; and eliminating the harmonic by means of active filtering.
