The explicit formula for the line - integrated emissivity with taking into account boundary effect is presented.

In this paper We discuss the initial problem of linear recursion equations with constant coefficients. A new explicit formula of solution is obtained directly by means of the Z-transformation.

We derive explicit formula for the doubly structured normwise backward error, and compare the results with the single structured case.

At each iteration, a master direction is obtained by solving one direction finding subproblem which always possesses a solution, and an auxiliary direction is yielded by an explicit formula.

The normwise structured backward error of an approximate eigen-pair is defined and its explicit formula is given.

For critical state model, the author derives an explicit formula of matrix H, which is used in implicit computation scheme.

When a inverse function of monotone function can not show the explicit formula, the distribution density curve of continuous randon variable can be gained with a parametric equation.
