5 试验设计的基本方法在计算飞行力学研究中,经常需要在计算机上进行大量的数值计算或试验。如何安排试验,大有文章可做。安排得好,可以事半功倍;否则,可能事倍功半,甚至劳而无功。70年代以来,我国广为流传并普遍实用的优选法和正交设计都是科学的试验方法,可以在计算飞行 5 The basic method of experimental design In the study of computational flight mechanics, it is often necessary to carry out a large number of numerical calculations or experiments on a computer. How to arrange the experiment, a lot of articles can be done. Arrange well, you can do more with less; otherwise, it may be more effective, and even relentlessly. Since the 1970s, the popular and generally popular optimization method and orthogonal design in our country are both scientific test methods that can be used in computational flight
