Some properties of adjoint matrix are discussed. The properties are symmetry, antisymmetry, positive definite, positive semi-definite, orthogonal and characteristic value.
An incorporative process in cooking with bleaching of cotton linter pulp with peracetic acid was optimized with orthogonal test and single-factor tests.
This paper uses orthogonal experiment to research on the synthesis technique of pseudo-ally lionone from citral and allylacetone. The product structure had analysed by IR.
By making a primary orthogonal regression test, the major factor and best parameter combination were found out, which supply theoretical basis for further research on awn-removed principle and awner.
