Witryna1 maj 2002 · The analytical expressions for the normal mode frequencies of a finite chain of masses and springs with two impurities are obtained. They show an explicit dependence on the impurity locations as well as the inter-impurity distance, in addition to the usual dependence on the mass defect and the force constant change parameters. WitrynaBy inserting 28 alkyl dimethyl ammonium ions into the product space of the modified bentonite, an organic bentonite is obtained. This is characterized by good Whiteness . It mainly comes from the modified bentonite. At the same time, its impurity content is relatively low, and it is suitable for cosmetics, oil-based mud, coatings, grease inks, etc.
