2 分词作定语的注意事项： i.分词短语可以作非限制性定语 Steady(稳定的) electric current can be produced(产生) by the electric cell(电池), invented(发明) by an Italian(意大利) physicist(物理学家). These particles(微粒), called electrons(电子), are moving around the nucleus(原子核). The nucleus(细胞核) controls(控制) some of the activities(活动) of the cell(细胞), including(包括) its reproduction(繁殖).

3 Most gas(气体) lasers(激光器), operating(工作) on the same basic(基本的) principle(原理), have the advantage(优点) of being able to emit(发射) their coherent(相干的) beams(光束) continuously(连续地). ii.一种特殊的定语（常见的是“using …”，表示方式） This chapter(章) deals with(论述) the implementation(实现) of Boolean(布尔) functions(函数) using these types of gates(门电路).

4 Let(让) us consider(考虑) a ballistic(弹道的) missile(导弹) launch(发射) using inertial(惯性的) guidance(制导).
iii.分词（特别是过去分词）作定语时的特殊译法 A. 顺译法 Distance(距离) is equal to(等于) speed(速度) multiplied(乘) by time. Current is voltage divided(除) by resistance(电阻). A lamp(灯) connected(连接) across a dry cell(干电池) is an example(例子) of a simple electric circuit(电路).

5 In this case, there is little power(能量) coupled(耦合) to the outside(外面的) world.
The diameter(直径) of the sun in meters(米) is given by the number(数字) 139 followed(跟) by seven zeros(零). B. 译成名词或动作 The waves(波) become weaker(更弱) with increasing(增加的) distance. This will also result in(导致) increased distortion(失真).
