| 在上海世博會充滿異國風情的展館和園區背后，有許多不為人注目的高科技看點作為支持；正是這些“隱身”的科技確保了游客們安全便捷地參與這場千載難逢的盛事。 |
The exotic pavilions and parks of the Shanghai Expo are supported by invisible high technologies that will ensure visitors enjoy the experience of a lifetime in safety and convenience. |
| “心”在門票里跳動 |
Tickets with heart |
| 上海世博會主辦方預測，世博園區的日均客流量可能達到80萬人次；傳統的人工檢票方式無法應付這樣龐大的參觀人群。為了應對如此龐大的客流量，同時做好防偽工作，主辦方將采用“射頻識別技術”，在0.5毫米厚的世博門票中安裝微型芯片，依靠自動檢票門來識別門票。該技術于上世紀90年代在日本興起，屬于一種非接觸式的自動識別技術。 |
The organizers expect 800,000 people to visit the Expo every day – a number that traditional, manual ticket checking cannot handle. To cope with the huge numbers and filter out fake tickets, tiny microchips in the 0.5 mm thin tickets will use a technology called "radio frequency identification," developed in Japan in the 1990s, to allow turnstiles to validate tickets without touching. |
| 類似的技術在超市及物流配送公司也有所應用；然而專家表示，上海世博會將是有史以來最大規模的射頻識別技術應用案例，這次盛會將大大推動我國在該技術領域的創新和發展。 |
Similar technology is used in supermarkets and by delivery and logistics firms, but experts say the Shanghai Expo will be the largest ever application of the technology and will boost innovation in the field. |
| 垃圾在地底飛奔 |
Trash flies underground |
| 人們在世博園中游覽的時候，就在他們的腳下，無數垃圾將以20米/秒的速度在地底飛奔。一套由地下管道、渦輪機和真空管組成的垃圾輸送系統能夠自動將垃圾箱中的廢棄物吸入輸送管道并運送到垃圾站。 |
While people walk around the Expo Park, beneath their feet trash will be flying underground at a speed of 20 meters per second. A system of tunnels, turbines and vacuum tubes has been devised to automatically suck trash from dustbins and deliver it to trash stations. |
| 當垃圾箱中的廢棄物達到一定的臨界值時，中央控制系統會啟動渦輪抽氣裝置，產生負壓氣流，將垃圾箱中的垃圾吸入輸送管道內。所有廢棄物最終將被傳送至垃圾站，經過分離、壓縮、過濾、凈化、除臭等過程后排到戶外。 |
When the amount of trash in dustbins passes a defined threshold, a central control system will switch on turbines to cut air pressure in the tunnels and suck in the trash, which is then separated, compressed, filtered, purified, deodorized and ejected at a trash station. |
| 水霧在腳下升騰 |
Cool, clear water |
| 本屆世博會將經歷上海夏季最炎熱的時候，因此主辦者想方設法為園區降溫，通過世博園區局地氣候調控工程，確保游覽者的舒適。 |
As the Expo will take place at the height of Shanghai's sweltering summer, the organizers have made great efforts to keep the park cool. The Expo's weather adjustment project will ensure people enjoy their visit in comfort. |
| 重要的展區和展館周圍都安置了亮麗的白色傘篷，連綿一片，為游客們遮擋烈日。 |
Stretches of beautiful white parasols in every major exhibition area and around pavilions will shield visitors from the burning sun. |
| 園區內的建筑物廣泛地應用了綠色環保建筑材料。地面鋪設材料則經過特別改良，可以讓雨水迅速滲透進地下滋養樹木，還能將地表溫度向地下散發，而非反射到大氣中。 |
Environmentally-friendly building materials have been used throughout. Specially modified road surface materials will let rainwater pass through to tree roots, and transmit heat underground instead of reflecting it back into the atmosphere. |
| 水體降溫是世博園區主要的溫控技術。園內的噴泉、水幕、水池和小河都能通過水分的蒸發帶走空氣中的熱量。在露天廣場，小型噴頭將水霧化成細小的顆粒散布在空氣中，起到良好的降溫效果。 |
The Expo's temperature reduction technology relies mainly on water. Springs, water curtains, pools and brooks in the park will cool the air by evaporation. And in open spaces, ultra-fine water particles will be sprayed into the air to cool visitors down.
