A .松动力矩-这个力矩是指在拆除一个没有负载的紧固件,从把它从静止的位置松下来的必要的开始力矩。

B.钳力矩 －存在于安装好的螺栓与螺母内部或是之间的一个力。这个力使得部件的组件之间更加紧密在一起。

C.驱动（推进）力矩－这个力矩必须使得紧固件在与贴合面快接触的拧紧时保持在运转状态.当大修说明书告诉你要拧紧到一个大于推进力矩的力矩值时，使用增加的推进力矩的值获得给定的力矩使得紧固件达到拧紧的时候,这个值可以从力矩扳手上读出来。

D. 干力矩-这个力

一般现在时的讲解及练习

一般现在时是英语中应用最广泛的时态之一，是初中英语语法重点。

一般现在时表示：

1．经常性、习惯性的动作或存在的状态。

e.g. I go to school on foot. He is very busy now.

2．表示主语的特征、性格、能力、爱好等。

e.g. He can swim. I work hard. I like watching TV.

3．表示客观真理。

e.g. There are seven days in a week. The moon moves round the earth. 其结构按正常语序，即“主语+谓语+其它”，有时为了起强调作用，时间状语也可提前.

其句式变化可分为两种情况：

1．表示动作， 一般人称作主语的，变否定句须在动词前加助动词don’t；变一般疑问句须在句首加助动词do。

E.g. They have lunch at 12:00.

They don’t have lunch at 12:00.

Do they have lunch at 12:00?

2．单三人称做主语的，变否定句须在动词前加助动词doesn’t；变一般疑问句须在句首加助动词does。

E.g. Jenny spea
