Specifies a variable - pitch font 指定间距可变的字体。
It has been well established by studies in reading that text printed with variable - pitch fonts is more readable than fixed - pitch font texts 阅读用可变字体打印的文本比用等宽字体的文本更易读,这已被确定。
Based on 1mw wind turbine design , this paper offers one reasonable variable - pitch structure , which can response quickly and operate conveniently 本文按照1mw风电机组总体方案要求,设计出一种结构合理,反应灵敏、操作方便的变桨距机构。
According to the effect of variable - pitch system , we can divide the operation process into three states : starting , below rated power and rated power 变桨距风力发电机组根据变桨距系统所起的作用可分为三种运行状态,即风力发电机组的起动状态、欠功率状态和额定功率状态。
