【正文】 ating mode of LAN is used in each 6 is widely used in development tools, The database uses Access The choice of system operating modeB/S and C/S structure in the two sort of modes is very popular in the , the client does need not to install the software, so it has important significance in the examination system of the distance the data security is low, and high demands on the server, which the data transmission speed is C / S structure is a traditional structure, which has proven technique, high security, low network traffic and fast response to our school room hardware and software conditions and the C language intelligent examination system ,which is to meet their own needs when selecting C / S structure of the system design.第二篇：專業(yè)英語翻譯Freeways,especially those built to Interstate standardsare the safest of the various classes of , control of access, which limits vehicle conflicts(車輛沖突), isa primary factor in relatively low accident, injury,and fatality rates(事故,死亡率), other design features, such as wide medians and shoulders roadsides clear of obstructions, and the extensive use of protective barriers(護欄), are key factors as ，是獲得較低的交通事故率和傷亡率的一個主 要因素。每個機房都采用工作組模式組成局域網(wǎng)。B/S結(jié)構是隨Internet發(fā)展而來的。Safety improvements on freeways can also result in substantial savings in life and property(生命和財產(chǎn))because freeways carry 25 percent of the nation’s total ，還會節(jié)約大量的生命財產(chǎn)資源，因為高速公路流量占了全國的總流量的25﹪。Any proposed use of lessthanfullstandard crosssection must be analyzed carefully on a sitebysite indicates that lane can operate safely if there are no other lessthanstandard features。Some studies have been made regarding the benefits of wider edge line markings(150 to 200 mm versus the standard 100 mm width).The wider markings may particularly benefit older （150到200毫米相對于100毫米的標準寬度）。鋼的彈性，同時保持在這個線性范圍，完全恢復。所應用的屈服應力不隨厚度而變化。這通常是橋梁，起重機，和支撐機械的結(jié)構物的問題，而且風和波浪荷載也可能引起疲勞問題。一旦開始，裂紋就會穩(wěn)定增長因為外力會提供撕裂鋼材所需的能量。像發(fā)生在更厚或者更大顆粒元素的鋼材中南，三向的幾何約束也會促進脆性，這是因為有更高的局部應力，因為在開裂過程中的更大的能量釋放和裂縫傳播的減緩。在某些類型的結(jié)構檢驗中，還需要有內(nèi)部的穩(wěn)定，例如鋼筋混凝土墻，加固土墻。當擋土結(jié)構擠壓墻后土體時，產(chǎn)生被動土壓力。一般土壓力楔體理論的公式（考慮了沿擋土墻墻面的摩擦）也可以用來計算墻體和填土面傾斜等其它所有情況下的水平分力。第五篇：專業(yè)英語翻譯1)Electricity can be measured in amount and 。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。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)應該使用開環(huán)控制方法。 the system expands and higher voltage levels bee necessary for transmission, the older transmission lines are often relegated to subtransmission ，舊的輸電線路往往被移交給中壓輸電功能。這樣的裝置稱之為電容器，其儲存電能的能力稱為電容。 synchronous machine as an AC generator driven by aturbine is the device which converts mechanical energy to electrical energy, in powers ranging up to ，同步電機是將機械能轉(zhuǎn)化為電能的設備，其功率范圍高達1500MW。（動名詞作介賓）Mechanization is using machines instead of hand 。（定語從句）The places where small puters can be used appear 。我們通常應當把線性電阻器僅僅稱為電阻器。阻抗不是一個相量，因此不能通過把它乘以并取其實部把它轉(zhuǎn)換成時域形式。另一種方法是求出每個獨立源對變量的作用然后把它們進行疊加。（賓語從句）Electrons always move toward where the potential is 。（表語從句）You should determine which of the following functions is 。 stations are usually located near a river or lake because large quantities of cooling water are needed to condense the steam as it exhausts from the ，這是因為需要大量的冷卻水在蒸汽從汽輪機排出時將其冷凝。 illustrated in , the aggregated load represented at a transmission substation(bus A)usually includes, in addition to the connected load devices, the effects of su
