关于塑料齿轮的一段英文表述！！！
标签：塑料齿轮 表述 英文
Applying the long-short addendum system in designing gears also decreases the amount of approach action that occurs as the teeth of mating gears are going through the initial stage of their contact. Approach action is more taxing in terms of wear than the recess action that takes place during the later stage of tooth contact. The elimination of undercutting and the reduction of approach action are particularly beneficial when the gears are of plastic.这是美国一本书的原话，我看着糊涂，请教各位，帮忙翻译下.
----------------多空增编系统中的应用设计齿轮，也减少了发生交配齿轮牙齿会通过他们接触的初始阶段的方式行动。方法行动征税在穿的方面比休会的行动，需要在稍后阶段齿面接触的地方。削弱消除和减少的方式行动，特别有利于塑料齿轮。
请问以上译文准确嘛？
翻译机就不要了！！
求高手
