| 摘 要： | 将实验数据库方法应用于侧喷与主流干扰的绕流单独体的复杂流动，得到了相似参数Q，即一比与干扰因子Kn、Km和Q之积的线性关系。应用该线性关系，成功地相关了关于Kn、Km和Q的实验数据，并使用这一关系式，很容易计算出干扰气动力和压力中心，计算结果表明，该 具有纠正实验偏差的能力，并提出了获得可靠实验结果的建议。

| Abstract: | Apply a method of experimental data base to flow around a body on which the interaction between main flow and lateral jet is occurred. A linear relationship between Q and the product of K n (or K m ) and Q is obtained. The experiment data about K n (or K m ) and Q is correlated and interference aerodynamic force and center of pressure is easily predicted by using that relation. The method have an ability to correct a experiment error, and some suggestions about obtaining good experiment data is yielded. |
