【正文】 ，可以傳遞信息。但信息只能從基地向車輛單向傳遞而不能反向傳遞，這樣駕駛員就不能濫用該系統(tǒng)與世界范圍內(nèi)的朋友和親戚通話。衛(wèi)星通信系統(tǒng)取代取代其他雙向移動通信系統(tǒng)的可能性不大，但是隨著歐洲范圍運(yùn)輸運(yùn)作的潛在擴(kuò)張，繼而1993年獨立歐洲市場的開放，衛(wèi)星通信以一種可靠及自發(fā)的方式，將離基地與千里之外的司機(jī)聯(lián)系起來，且成本也認(rèn)為是便宜的。運(yùn)輸中的信息技術(shù)物流研究院的管理學(xué)專家所作的報告指出，信息技術(shù)正快速應(yīng)用于物流配送過程，該項支出數(shù)量為總營業(yè)額的2%。信息技術(shù)（IT）的方式相當(dāng)簡單，據(jù)此可精確地收集信息，充分分析、傳輸給所有機(jī)構(gòu)內(nèi)外的相關(guān)職能部門，并由具有相關(guān)決策職能的部門傳播。今天許多有效的運(yùn)輸和配送運(yùn)作都完全依賴可靠的IT系統(tǒng)（如“準(zhǔn)實時”庫存原理，視快速有效的通信系統(tǒng)為關(guān)鍵），與顧客、供應(yīng)商和承包商進(jìn)行信息交流。在信息技術(shù)中，一個快速發(fā)展的領(lǐng)域是電子數(shù)據(jù)交換（EDI），通過它，運(yùn)輸或配送企業(yè)接受訂單、交換文件和發(fā)貨清單，并通過直接信息聯(lián)系進(jìn)入自己的系統(tǒng)，完全消除了通過郵政和信使傳遞文件的延誤、錯誤和其他困難。EDI系統(tǒng)的優(yōu)勢是提供快速精確的訂單傳遞和處理（以最小的直接成本），并具有降低庫存水平的潛能。專家在給物流研究院的報告中指出，出現(xiàn)了遠(yuǎn)離IT信息中心集中的計算機(jī)這樣一個趨勢趨勢，而使用個人微機(jī)在線運(yùn)作或連到中央主機(jī)上的人正在增加。第三篇：專業(yè)英語翻譯1)Electricity can be measured in amount and 。2)Instrument transformers are installed on the highvoltage 。3)Electric power is generated in power generating stations or 。4)The meters are calibrated and the scale is designed to read the value of the desired ，以便讀出期望的數(shù)值。5)Electrical energy can be stored in two metal plates separated by an insulation a device is called a capacitor, and its ability to store electrical energy is termed is measured in ，這樣的裝置被稱為電容器，它儲存電能的能力就被稱為電容。電容的測量單位是法拉。1)The signal should be filtered before it is signal should be filtered before being ，應(yīng)先對其進(jìn)行濾波。2)An object bees is placed in the being placed in the sun, an object bees 。3)We must do various experiments before a new electronic product is designing a new electronic product we must do various ，我們必須做各種實驗。4)Changing resistance is a method for controlling the flow of the 。5)Conducting electricity means the flow of electrons through an 。1)The power supply, which is shown in blockdiagram in , is a singlephase switchmode power supply shown in blockdiagram in is a singlephase switchmode 。2)A threephase circuit, as it was pointed out above, is merely a bination of three singlephase threephase circuit, as pointed out above, is merely a bination of three singlephase ，三相電路只不過是三個單相電路的組合。3)The transistor, which is working with correctly polarities, can work as an transistor working with correctly polarities can work as an ，作用就像放大器。1）The capacity of individual generators is larger and larger so that the increasing demand of electric power is capacity of individual generators is larger and larger to satisfy the increasing demand of electric ，目的就是滿足不斷增長的用電需求。2)What does a fuse do? It protects a function of a fuse is to protect a 。1)If it is possible, the openloop control approach should be used in this possible, the openloop control approach should be used in this ，這個系統(tǒng)應(yīng)該使用開環(huán)控制方法。2)As illustrated in , there is a feedback element in the closedloop in , there is a feedback element in the closedloop ，這個閉環(huán)系統(tǒng)中有一個反饋元件。3)The device includes an instrument transformation and a relay system which has two circuits in device includes an instrument transformation and arelay system with two circuits in 。1)It has been mentioned above that the electrons in a metalare able to move freely through the metal, that their motion constitutes an electric current in the metal and that they play an important part in conduction of ：金屬中電子能自由地通過金屬，電子的移動在金屬中形成了電流，電子在熱傳導(dǎo)中起著重要的作用。2)The reluctance motor operates synchronously at a speed which is determined by the supply frequency and the number of poles for which the stator is ，該速率是由電源頻率和定子繞制
