Specifies a variable - pitch font 指定間距可變的字體。
It has been well established by studies in reading that text printed with variable - pitch fonts is more readable than fixed - pitch font texts 閱讀用可變字體打印的文本比用等寬字體的文本更易讀,這已被確定。
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風電機組總體方案要求,設計出一種結構合理,反應靈敏、操作方便的變槳距機構。
According to the effect of variable - pitch system , we can divide the operation process into three states : starting , below rated power and rated power 變槳距風力發電機組根據變槳距系統所起的作用可分為三種運行狀態,即風力發電機組的起動狀態、欠功率狀態和額定功率狀態。
