a measure of the resistance to flow of a fluid under an applied force
造句
Understanding of the outer cores bulk viscosity will help us to infer the anelastic properties of the inner Earth. 研究外核液態鐵的體粘滯度對認識地球內部非彈性性質具有重要意義。
To get around this viscosity, scientists from the University of Sheffield in England and their colleagues have developed plastic swimmers without moving parts. 為了解決這個黏滯度的問題，英國雪菲爾大學的科學家發展出一種不具備打水部件的塑膠泳器。
