1·The equations are solved numerically using the method of Gauss elimination and under-relaxation iteration by computor, thus the air flows in every branch are determined.

采用高斯消去法和欠松弛迭代法并应用计算机对这些方程进行数值求解，从而计算出各支路的流量。

2·On the basis of the multiprocessor platform, TMS320C80's programmable structure, the parallel matrix multiplication and parallel Gauss Jordan elimination algorithms are introduced.

基于多处理机平台TMS32 0C80 （C80 ） ，提出并行矩阵乘法和并行高斯约当消元法。

3·Different means are used for different kinds of noise respectively. The edges of target and background are enhanced and the elimination of Gauss noise and pulse noise are reduced.

该算法对红外图像处理过程中不同类型的噪声采用不同的方法滤波，有效地滤除了高斯噪声和脉冲噪声，同时增强了目标和背景中的边缘成分。
