hot and bothered antiprotons and positrons to couple is quite a task.───高溫與高速運動狀態的反質子和正電子進行結合是一樁非常困難的工作。
The antiprotons are then pushed into the same trap as the positrons and left to mingle for a second or so.───然后將反質子推入到裝有正電子的容器中,用大約一秒鐘的時間等待它們混合。
The process would also create large numbers of electrons and positrons at the core of the Milky Way.───這個過程也會在銀河中心產生大量的電子和反電子。
But the lightning flash detected by Fermi appeared to have produced about 100 trillion positrons: "That's a lot, " he said.───不過,費爾米發現的閃電似乎產生了一百萬億正電子,“那可是個天文數字,”他說。
To make cold antihydrogen, the experimenters must slow down the antiprotons to a temperature similar to that of the positrons.───要制作冷的反氫,實驗者必須將反質子減緩到與正子相近的溫度。
It needed some years of development by the experimenters before the fact of the existence of positrons was established.───確立存在正電子這個事實還需要幾年的實驗發展。
If the material being tested has no defects in it, the positrons react a little differently.───如果所探測的材料不存在缺陷,正電子則表現得稍有不同。
In the case of a material with a defect, the positrons are trapped at nano-sized defects in the material.───如果材料有缺陷,這些正電子可以捕捉到納米尺寸的材料缺陷。
Meanwhile, positrons from the decay of a form of radioactive sodium are separately slowed and accumulated.───同時,來自放射性鈉一種形式的衰減正電子被慢慢分開且累積起來。
Positrons and antiprotons can individually be stored in a device called a Penning trap, which uses a combination of magnetic and electric fields to hold charged particles in a vacuum.
For example, a cylindrical Penning trap that holds positrons will not hold antiprotons.
Electrons and protons are forms of ordinary matter, but positrons are antimatter particles.
The positrons are generated will move around in the material.
The Dark Era begins when space is dominated by tiny particles such as photons, electrons and positrons.
Instead they would produce gamma rays, neutrinos and antimatter such as positrons and antiprotons, Gondolo said.
