试题解析

风力发电机组

风力发电机组是将风的动能转换为电能的系统。 风力发电机组包括风轮、发电机;风轮中含叶片、轮毂、加固件等组成;它有叶片受风力旋转发电、发电机机头转动等功能。风力发电电源由风力发电机组、支撑发电机组的塔架、蓄电池充电控制器、逆变器、卸荷器、并网控制器、蓄电池组等组成。风力发电机组进行发电时,都要保证输出电频率恒定。这无论对于风机并网发电还是风光互补发电都非常必要。 要保证风电的频率恒定,一种方式就是保证发电机的恒定转速,即恒速恒频的运行方式,因为发电机由风力机经过传动装置进行驱动运转,所以这种方式无疑要恒定风力机的转速,这种方式会影响到风能的转换效率;另一种方式就是发电机转速随风速变化,通过其它的手段保证输出电能的频率恒定,即变速恒频运行。

齿轮油

齿轮油主要指变速器和后桥的润滑油。它和机油在使用条件、自身成分和使用性能上均存在着差异。齿轮油主要起润滑齿轮和轴承、防止磨损和锈蚀、帮助齿轮散热等作用。汽车齿轮油用于汽车转向器、变速器以及驱动桥等齿轮传动机构中,由于齿轮传动时表面压力高,所以齿轮油对齿轮的润滑、抗磨、冷却、散热、防腐防锈、洗涤和降低齿面冲击与噪声等方面起着重要作用。

Cloze 5  “I’ m really thankful to our governing, for it provides us with such a good training program. The training greatly helps us live well. I will certainly study hard and learn the skills. Then I can  1   my family difficulties and do good to other people.” a learner on the job training program said, feeling  2  .  The learner’s grandfather is nearly 80 years old, and his mother is  3   in bed. So his father, who is a farmer, is the main  4   of the family. The family is poor. The learner graduated from high school and did not  5   the college entrance exam. The job training pro- gram helps him learn the skills that he’ll  6   in the workplace.  The story reminds me of another  7  . It goes like this: Once upon a time, there was a man who liked fishing very much, and was  8   to catch lots of fish every day. The man was a kind-hearted person, so he always  9   his fish with his neighbors who did not know how to fish. One day, he thought that it would be  10   if he taught them how to fish. So he  11   his neighbors together and showed them how to fish. Everybody was very happy that they could  12   the fish they themselves caught.  At present, there are still a lot of poor people throughout the world. But it’s not good if we give only  13   to them.  14  , we should give them a chance to learn new skills. Therefore, a technical training is very important to people in need, and they will learn the ability to  15   money. People can learns lot of useful things in the training program and what they learn can help them on the way to find jobs.
