　　The U.S. Secret Service estimates that some $1 billion of counterfeit U.S. dollars are printed every year. Ninety percent of that amount is confiscated by authorities before distribu- tion，but that still leaves $ 100 million floating around the world at any one time. People worry about getting stuck with funny money， and some buy devices that can help them determine whether a bill is counterfeit. The most common type of detector uses ultraviolet light to spot a bill that has been bleached and then reprinted ——a recent counterfeiting technique.　　

　　美國聯(lián)邦經(jīng)濟(jì)情報(bào)局估計(jì)，每年有十億美元的假鈔印刷出來。其中有百分之九十的假鈔在進(jìn)入流通之前就被有關(guān)當(dāng)局沒收，但還是有一億美元會偶爾流到世面上。人們?yōu)槭盏郊兮n而發(fā)愁，有些人購買了能夠幫他們鑒別假鈔的儀器。最常用的探測器用紫外線識別經(jīng)漂白后又重印的紙幣——一種最近發(fā)明的防偽技術(shù)。

　　Now comes a new device for discovering bogus bucks that is more convenient than competing products ， and as effective. It is called the Vistatector. Every major currency in the world，except French francs and West German marks printed before 1973， has magnetic particles embedded on the face of the bill. The particles （which enable counting machines to process stacks of money） are present in the printing ink and lie on certain predetermined spots on individual bills. The Vistatector is a penlike device that uses electronic circuit to detect whether the magnetic particles are present on a bill —— and if so， if they are located where they should be.　　

　　現(xiàn)在出現(xiàn)了一種新的探測假幣的裝置，這種裝置比與之競爭的其他產(chǎn)品更為方便，且同樣有效。它就是展測儀。世界上的各種主要貨幣，除了法郎和1973年之前印刷的西德馬克外，在紙幣的表面嵌有磁粉。這些粒子（粉末）（能使計(jì)數(shù)機(jī)對大量的錢進(jìn)行分理）存在于油墨中，并在各張紙幣的預(yù)定點(diǎn)顯現(xiàn)。展測儀是一種鋼筆形狀的儀器，用電子線路查出紙幣上是否存在磁粉——如果紙幣上是有磁粉的，那么還要看它們是否在準(zhǔn)確的部位。

　　Users rub the bottom of the “pen” back and forth across two different spots on a bill， and indicator lights signify whether magnetic particles are embedded in those areas. If the bill is genuine， the product will show the presence of particles in one spot and the absence of them in the other. Unlike ultraviolet detectors that require the user to make subjective color comparisons to determine the authenticity of a bill， the Vistatector requires no human decision making.

　　使用者用“筆”的底部在紙幣上的不同點(diǎn)來回擦拭，指示器的光線顯示所經(jīng)部位是否嵌有磁粉。如果紙幣是真的，該產(chǎn)品就會顯示有的部位有磁粉，有的部位無磁粉。和紫外線探測儀不同的是，紫外線探測儀需要使用者要與主觀的顏色進(jìn)行對比以確定紙幣的真?zhèn)危箿y儀則無需憑藉人的判斷能力。
