1　引　言

随着我国化工仪表行业与国外技术交流的不断扩大,化工仪表科技英语的翻译显得越发重要。国外一些知名厂商纷纷在我国设厂办公司,给我们带来了大量的先进设备和制造技术,这就更有力地推动了我国化工仪表行业的技术进步,同时也促进了我国化工仪表翻译工作的繁荣。本文着重介绍化工仪表英语的特点及英汉翻译技巧。

2　正序译法

所谓正序译法,就是按照一个句子正常语序一直译下去,不加任何顺序的改变,使译文条理和句意清晰。如:

例1 SeriesV800/80 heave-duty double-seat-ed, top and bottom-guided globe control valve aredesigned for stable, accurate contro.l译文:V800/80系列阀被设计成具有重型双座,带有上下导向装置的球形控制阀,该阀拥有控制稳定,定位精确等控制功能。

例2 Connect the certified gas the same pres-sure as the sample gas, in order to obtain thesame flow as the same gas, wait to obtain a steadyvalue.译文:连接好标气,使其与样气的压力、流量相同,并等待得到一个稳定值。

例3 Adjustment of zero has negligible effecton span, adjustment of span has a significanteffecton zero.译文:零位调整对量程而言可以忽略不计,而量程调整的确影响零位。

3　反序译法

所谓反序译法,即先译出句子的后半部分,再译出句子的前半部分,或从句尾依次向前推进译出全句,使整句符合汉语的表达习惯。如:

例4 Zero suppression is required when agage pressure, or a differential pressure transmit-terwith a sealattached to the high side ismountedbelow the seal/process connection.译文:当一台差压变送器的高压侧安装低于密封或工艺连接件时,这时就存在一个表压,清零就成为必然了。

例5 Zero elevation is necessary when thesame transmitter is mounted above the seal/process connection.译文:当同样一台差压变送器的高压侧安装高于密封或工艺连接件时,这时零高程就存在了。

例6 This gauge comprises a self-recordingapparatus to record the variation ofpressure duringoperation ofmachine.译:在机器运行期间,这块由一个自动记录仪组成的压力计,它是用来记录该机器的压力变化的。

例7 The resistance of any length of a con-ductingwire is easilymeasured by finding the po-tentialdifference in volts between its endswhen aknown current is flowing. 译文:已知导线中的电流,只要求出导线两端电位差的伏特数,就不难测出任何长度的导线的电阻。

4　增词译法

在译文中增加原文中无其词但有其意的一些词语。如:

例8 Sensor switches are loaded near the endof each feed bel.t译文:各传感开关都装在每条给料皮带的末端附近。(增补指示词)

例9 The pointerof themetermoves from zereto two and goes back to zero again.译文:表的指针先从0指向2,然后又回到0。(增补关联词)

例10 Other liquids being too ligh,t a barom-eterusesmercury.译文:由于其它液体太轻,因此,气压表用水银。(增补关联词)例11 The bestconductorhas the least resist-ance and the poorest the greates.t译文:最好的导体电阻最小,最差的导体电阻最大。(增补“导体电阻”)

5　减词译法

原文件中的一些词语不译出来,但仍然能保持原文的基本含义,使得译文更加精练。如:

例12 A rotary valve can be installed in yourpipeline in anymounting direction, and its actua-tor does notneed extra suppor.t译文:球形阀可以在您的管线上以任何方向来安装,执行机构也无需额外支撑。(省略物主代词its)

例13 Different instruments differ in theirproperty.译文:不同的仪表具有不同的性能。(省略物主代词their)

例14 The electrodes are drilled and fastenedto tubing through which gas is supplied to thecel.l译文:电极需钻孔并固定在管道上,通过电极的工艺气体被输送给电池。(省略物主代词which)6　分译法所谓分译法,即把一个句子中含有两个或两个以上含义的句子分开来译,使原文比较复杂的结构更加简单化,条理更加清晰明了。如:例

15 Themaximum orminimum span can benomore orno less the height (H) of the processfluid level times the specific gravity (sp) of theprocess liquid.译文:量程的最大值不得大于工艺液位的最大高度乘以工艺液体的比重;量程的最小值不得小于工艺液位的最小高度乘以工艺液体的比重。(注:该量程指双法兰差压变送器的量程)

例16 The indicatingmeter or test equipmentshunts the diodewhen connected to the test termi-nals and as long as the voltage across the terminalsis kept below the diode’s threshold voltage, nocurrentpasses through the diode.译文:将指示仪或测试设备与二极管并连,此时,电压就通过接线端子使二极管保持在一个临界电压值,二极管无电流通过。
