加拿大發明「量子隱形」
Making oneself invisible has long been considered pure fantasy. From Athena’s cap of invisibility to Harry Potter’s invisibility cloak, mankind has often imagined what they could do with such magical objects.
數千年來，隱形一直被認為是純粹的幻想，從雅典娜的隱形帽到哈利波特的隱形斗篷，人類一直在想像若是能夠隱形，可以做到什麼事，
invisibility cloak隱形斗篷
Now, thanks to technological advancements, our fantasy has been brought one step closer to reality.
現在，科技的進步讓我們離夢想又更近了一步。
advancements=progress進步
Hyperstealth, a Canadian manufacturer of military camouflage uniforms, recently released a material called Quantum Stealth.
加拿大軍用迷彩服製造商Hyperstealth最近發表了一種名為「量子隱形」Quantum Stealth的材料，
camouflage(n.)(軍事)偽裝、掩護material(n.)材料;材質
This paper-thin technology can bend the light around an object, altering its perceived position or making it seemingly vanish.
是一款薄紙技術，可折射物體周圍的光線，改變其位置或使其看起來消失，
alter(v.)改變;微調perceive(v.)察覺;注意到;意識到vanish(v.)消失=disappear
In a video presented by Hyperstealth, a miniature tank covered with a sheet of Quantum Stealth does not come into view until the material is moved to the side.
在Hyperstealth發表的影片中，把「量子隱形」蓋在玩具坦克車上，從上往下也完全看不到坦克車，要把材料移開才會發現原來底下有東西。
miniature(adj.)微型的;小型的;微小的not…until…直到…才come into view映入眼簾
In another clip, the material is placed in front of what seems to be a tree, but it reveals a housing complex after it is moved.
在另一個影片中，「量子隱形」被放置在看起來像是一棵樹的物體前面，但移開後竟出現建築物。
what=the thing that or whicha housing complex建築群
This feature makes Quantum Stealth ideal for use on the battlefield, as it can conceal large entities from view to some extent, such as troops, artillery, tanks, and even buildings.
這個特點讓「量子隱形」成為理想的作戰裝備，因為它可以在一定程度上隱藏大型實體，例如部隊、火砲、坦克甚至建築物。
conceal(v.)隱藏=hidereveal(v.)顯露=showentity(n.)實體;獨立存在體object(n.)物體
While the visual effects are amazing, the physics behind the technology is actually quite straightforward.
儘管視覺效果令人驚嘆，但實際上物理學非常簡單。
straightforward(adj.)容易理解的、簡單的、(人)坦誠的、直率
Every material has a refractive index, a numerical value of the speed of light traveling in that material compared with its speed in a vacuum.
每種材料都有一個折射率，也就是光在真空中的傳播速度與光在該介質中的傳播速度之比，
refractive index折射率compared with~相較於vacuum(n.)真空
When light moves between two materials, the angle at which it is moving will change depending on the refractive index, making it possible to create something with a blind spot.
當光在兩種材料之間移動時，角度將根據折射率而變化，從而可以創造視覺盲點，
at…angle依照、按照…的角度depending on~視…而定blind spot盲點;視線盲區；(尤指)駕車時的視線死角
The principle is known as Snell’s law, and that is how the invisibility shield works.
這項原理被稱作「司乃耳定律」，就是「量子隱形」背後的原理。
shield(n.)
Hyperstealth has been developing Quantum Stealth for years but has only recently applied for patents.
Hyperstealth多年來一直在開發「量子隱形」技術，但直到最近才申請專利，
apply for~申請patent(n.)專利
It might not be long before the material finds application in the latest camouflage gear.
這項材料可望在不久之後應用於最新的迷彩服裝備。
It might not be long before…不久後…apply(v.)應用;申請application(n.)應用(程式)gear裝備
