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.
OBJECTIVE The optimum extraction conditions of shionone from herbs Tatarian aster root were studied by means of orthogonal test and microwave-assisted and pressurized solvent extraction technique.
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.
