Their initial calculations and scale-modelwind-tunnel experiments convinced them they wouldn't need a strong wind to lift the 33.5-tonne column.
他们最初的计算和风洞比例模型实验使他们确信，不需要强风就能提起33.5吨的柱子。

And at least one group has built a physical model based on fossils and put it in a windtunnel.
至少，有一个研究小组根据化石建造了一个身体模型，然后将其放到一个风道里。

Windtunnel test of sectional model is an important means for determining lock-in region of wind speed and maximal amplitude of vortex-excited resonance.
