启动风速

小型风力发电系统尚存在启动风速高、蓄电池寿命短、风能利用系数低等问题需要进一步探讨解决。

Some problems such as high start-up wind speed , short life of storage battery and low utilization coefficient of wind energy that exist in small wind power system need to be further discussed .

利用搭建的简易开放式通风实验台，实验研究了所研制的一种具有自动捕风功能的通风装置的最小启动风速、反应时间等机械性能及通风性能。

Studies the mechanical performance such as minimum start-up air speed , reaction time and ventilation performance of the catcher developed by the authors on the simple opening ventilation test-bed .

建立了临界启动风速的随机模型，推导出含有随机变量（偏心距、偏心角、支持角以及接触角）的临界启动风速的解析表达式。

We established the stochastic model of threshold friction velocity , and derived an analytical expression of the threshold friction velocity with random variables ( the eccentricity , the eccentricity angle , support angle and contact angle ) .
