In the recent 10 years, at the three special fields of dynamic aerodynamics, although the circumferential Reynolds number gap between wind tunnel free flight and its corresponding real flight is as high as one or two magnitudes, wind tunnel free flight experiment results succeed in predicting or reproducing the dynamic aerodynamic characteristics in the three special fields, which appear in the real flight phase producing severe effects on flight security and flight performance.

近10余年来，在3个动态气动专题领域内，地面风洞自由飞实验与对应的天空飞行器的绕流雷诺数虽然相差1～2个量级，但风洞自由飞实验结果多次预测或再现了天空飞行器出现的对飞行安全、飞行性能产生严重影响、其它地面风洞实验方法难以预测或再现的这3个专题领域内的动态气动特性，这至少为3个专题领域内天地动态气动相关中的雷诺数影响，提供了一个新的理解。

While we have made significant progress in our understanding of the human body and of life, still we find that the vital health and youthfulness we're looking for is somewhat elusive.

How infinite and inexpressible a Blessing it is, that the Knowledge of God, and of the Doctrine of Salvation by Christ Jesus, is so plainly laid down in the Word of God; so easy to be receiv'd and understood: That as the bare reading the Scripture made me capable of understanding enough of my Duty, to carry me directly on to the great Work of sincere Repentance for my Sins, and laying hold of a Saviour for Life and Salvation, to a stated Reformation in Practice, and Obedience to all God's Commands, and this without any Teacher or Instructer; I mean, humane; so the same plain Instruction sufficiently serv'd to the enlightning this Savage Creature, and bringing him to be such a Christian, as I have known few equal to him in my Life.
