“characteristic polynomial”簡單造句，characteristic polynomial造句子

HMO characteristic polynomial and select eigenvalues for many heterocyclic benzenoids are calculated by using chemical graph theory methods.

The formulae for the number of loops, edges, triangles, pairs of two-way nodes and pairs of one-way nodes are deduced by the coefficients of a characteristic polynomial, so on.

In this paper, we present an iterative method for determining whether all roots of characteristic polynomial are on the left half-plane.
