鸭式无尾翼布局具有高度机动性和优越的超音速性能，但亦具有先天空气动力上之不稳定性。

The tailless delta-canard configuration is inherently aerodynamically unstable, which provides a high level of agility, particularly at supersonic speeds.

不过即使是具有不确定性的数据看上去也聊胜于无。

Still, even uncertain data seems better than none at all.

采用无因次分析法得到了预测系统稳定的经验关系式，并得到了判断系统稳定性的界限图。

By means of dimensionless analysis an experimental correlation for predicting stability of system is obtained and stability threshold diagrams have been found.

Now, part of the appeal of not making any qualitative distinctions about the worth of people's preferences, part of the appeal is that it is nonjudgmental and egalitarian.

不对人们选择的价值，进行定性区分,其魅力就在于，它是无偏见的，平等主义的。
