中文说明：离心叶轮三元设计往往由一维热力设计做起，这也是最为关键的一步，此程序可以使得设计人员通过调节核心经验参数（注释给命出了取值范围），并通过验证相关核心参数达到最优设计，本程序针对高速风机设计十分有效，低速风机可以少改程序将初值的选取及其验证通过matlab程序循环语句实现更为奏效。
English Description：
Centrifugal impeller ternary design often by a dimension thermal design do up, this is most key of a step, this program can makes design personnel through regulation core experience parameter (comments to life out has take value range), and through validation related core parameter reached optimal design, this program for high-speed wind machine design is effective, speed wind machine can less modified program will initial of selected and validation through MATLAB program cycle statement achieved more worked.
