This model accounts for the uncertainty about the loads acting on the wind-turbine rotor blade by the unstable wind distribution. A 20-year design lifetime is considered.
该种模型考虑了由于风速的不稳定所带来的作用在风力机叶片上分布载荷的不确定因素,并假定风力机的设计寿命为20年。
On the other hand, the diffusion is corresponded with coefficients of turbulent diffusion and wind distribution, the range of horizontal diffusion is greater than that of vertical diffusion.
催化剂的扩散与湍流扩散系数、风场分布相对应,水平扩散范围大于垂直扩散范围。
