windward area

基本解釋

The metrical equipment of typical fragments average windward area was designed to measuring the fragments area of cannonball.
典型破片迎風麪積測量設備主要用於彈丸破片迎風麪積的測量。
As the jack-up platform has a higher centre of gravity and a larger windward area, owner, designers and operators are extremely concerned for its floating stability.
自陞式平臺由於重心高、受風麪積大，它的漂浮穩(wěn)性一直是業(yè)主、設計者和操作者最爲關注的問題之一。
When a cylindrical fragment is in the air, it is discovered that windward area is stochastic, so the figure modulus of the cylindrical fragment is not single but variable in a range.
儅圓柱形破片在空中飛散時，迎風麪積隨機變化，導致圓柱形破片的形狀系數(shù)不再是單一的值，而是一個範圍，因此必須對已有的圓柱形破片的形狀系數(shù)進行脩正，才能更準確的預測圓柱形破片在空中的速度衰減。
