单词 decomposition
释义
decomposition
Mathematics

  • The breakdown of a quantity or expression into simpler components. For example, 24 = 2×2×2×3 is the decomposition of 24 into its prime factors or the expression of a polynomial as a product of factors. More generally, decomposition might refer to the breakdown of a space into significant components, for example a vector space written as a direct sum of eigenspaces.

Chemistry

  • 1. The chemical breakdown of organic matter into its constituents by the action of bacteria and other organisms.

    2. A chemical reaction in which a compound breaks down into simpler compounds or into elements.

Chemical Engineering

  • 1. A chemical reaction in which a compound breaks down into more simple compounds or into elements.

    2. The chemical breakdown of organic matter into its constituents by the action of bacteria and other organisms.

    3. The factorization of an integer into other integers that are second- or third-degree (squares or cubes).

Computer

  • 1. In switching theory, the realization of an n-variable switching function as a composition of functions, each of which has less than n variables. Like other minimizations, decomposition is facilitated by Karnaugh maps.

    2. In programming, the analysis of a problem into simpler subproblems. See modular programming, program decomposition.

Biology

  • The chemical breakdown of organic matter into its constituents by the action of decomposers.
