求翻译英语文章，人工的，机器的不行！好再加分！

It is evident from Figure 3 that wave energy converters
require a high peak to average rating,and so will operate
close to their peak or overload current ratings for a
significant proportion of the time.This represents a further
complication in the employment of brushed machines.In a
recent publication sponsored by Vestas Wind Systems
[20],it was discovered that under high current operation
brush-slip ring systems can periodically enter film
instability modes that are characterised by severe brush
wear and high brush temperature,increasing the wear rate
by approximately 40%more than the expected wear rate.

The other factors that inhibit good brush film formation
are high humidity and the presence of chemical
contaminants in the air.While these environmental factors
are issues for offshore wind turbines also,humidity and
air vapour control are being built into modern offshore
wind turbines for these reasons[11].The inclusion of such
air quality control in the generator enclosure of OWC
WEC is less feasible since the generator is located in an
airflow path that is in direct contact with the sea.

The minimum brush life of a general purpose,slip ring
machine is typically 3,500-8,750 hrs.The effective
operating period of a WEC at a good site is around 5,000
hrs annually.Thus,in order to avoid costly outages,or
even generator damage,the brushes ought to be changed
at least twice annually,which corresponds with best
practice in the wind industry.

Answer 1

我看过这本书，意思应该是这样的
显示波能转换器相对均值已经达到峰值，因此，大部分时间会接近于峰值或者超出负荷，这就表示电刷发电机要在更复杂的情况下运行。在Vestas Wind Systems最新出版物中，发现电刷集电环组件在高电流负荷情况下运行会周期性的进入不稳定状态，主要表现在电刷严重磨损和发烫，损耗比预期增加大约40%左右。另外，空气中的高湿度和化学物也会抑制电刷运行。这些环境因素也会干扰离岸风能涡轮发电机，所以现在风能发电机都有湿度和水蒸气控制系统。这种空气质量控制系统运用在OWC和WEC中都是不太好实现，因为发电机都是直接安装在海边风口。通用电刷在集电环发电机中最少可以使用3500~8750小时。WEC在一个好位置的使用时间是每年5000小时。因此，为了避免高成本损耗或者发电机损坏，使风能发电机发挥最大作用，所以电刷应该每年都换两次哦
我是认真打得字，希望你满意，祝你学习进步。请及时采纳 谢谢了

Answer 2

图3不难看出,海浪的能量转换器
需要一个高峰,平均得分,操作
接近他们的级别达到顶峰或者负载电流
绝大部分的这代表了进一步
