windspeed

Some extreme design boats are capable of traveling faster than the true windspeed .

一些极端的设计船能够行驶速度超过了真正的风速。

It was found that the profile of windspeed above waves is logarithmic and the momentum flux near waves is constant .

测量数据表明水面上风速分布符合对数律，水气界面附近存在小范围的动量交换常通量层。

The aerovane is frequently used to measure windspeed .

风向风速仪经常用来测定风速。

On the other hand , in nighttime , the transpiration mainly depend on temperature , windspeed , and saturation vapor pressure , etc.

作物夜晚的蒸腾变化主要受气温、风速、空气饱和差等因素的影响。

Optimal spacing intervals between windbreaks could be predicted from the indices of a given windbreak structure , percentage of reduction of windspeed desired and tree growth model .

因此，树木林带的主带间距可以通过林带结构系数、希望降低风速的比例和树木生长模型来确定。

The underlying surface ( soil , vegetation , landform etc. ) provides matrix of wind erosion , while climatic conditions ( windspeed , wind , etc. ) are dynamic factors of wind erosion .

下垫面（土壤、植被、微地貌等）是风力侵蚀发生的基质条件，气候特征（风速、风向等）提供了风水侵蚀发生的动力条件。
