在 中文 中使用 正电子 的示例及其翻译为 英语

所有288名实验对象也接受了正电子发射断层扫描（PET）以跟踪大脑中的T蛋白水平，特别是在已知调节记忆的颞叶区域。
All 288 subjects also underwent positron emission tomography(PET) to track tau levels in the brain, particularly in a temporal lobe area known to regulate memory.

大脑成像：一些像正电子发射断层扫描（PET）和功能性磁共振成像（fMRI）的技术可以让人们监测大脑的活动。
Technologies such as positron emission tomography(PET) and functional magnetic resonance imaging(fMRI) allow the activity of the living brain to be monitored.

这里也是物理学家卡尔安德森发现正电子的地方。
This is also where physicist Carl Anderson discovered the positron.

反电子(称为正电子)的行为像电子，但带正电荷。
Anti-electrons(called positrons) behave like electrons but have a positive charge.

但是他们必须非常彻底地检查数据以确保正电子不是来自其他背景过程。
But they will have to check the data extremely thoroughly to make sure that the positrons didn't originate from other background processes.

当质子以140度撞击锂时，产生的电子和正电子比预期的更多。
When the protons hit against the lithium at 140 degrees, more electrons and positrons were created than were expected.

正电子的存在首先由Dirac提出，在20世纪30年代通过实验得到证实。
The existence of the positron, first predicted by Dirac, was experimentally identified in the 1930's.

最终，其中一条伽马射线遇到星光的光子，伽马射线转化为电子和正电子。
Eventually, one of the gamma rays encounters a photon of starlight and the gamma ray transforms into an electron and a positron.

电子和正电子很小很轻，因此FCC对它们进行加速和碰撞要容易得多。
Electrons and positrons are very small and light, so they're much easier for the FCC to accelerate and collide.

比如，香蕉也会产生反物质--它每75分钟会释放出一个正电子。
For example, bananas release one positron- the antimatter equivalent of an electron- roughly every 75 minutes.

在狄拉克的计算中，电子和正电子的相互湮灭始终产生光，不能传递其他电子的能量。
In Dirac's calculations, a mutual annihilation of an electron and positron always produces light and cannot impart energy on other electrons..

携带带电荷的正电子粒子很难在地球上探测到，因为它们可以被行星的磁场偏转。
Particles like positrons that carry an electric charge are difficult to detect on Earth since they can be deflected by the planet's magnetic field.

这是因为电子和正电子具有质量，这个新产生的质量必须来自碰撞粒子的能量。
That is because an electron and positron have mass, and this newly created mass must come from the energy of the colliding particles.

例如，正电子辐射断层扫描(PET)技术用于探测很多种癌症，准确率非常高。
For example, positron emission tomography(PET) is used to detect many kinds of cancer with great accuracy.

当电子和正电子之间有一个大角度时，他们发现了一个偏离他们期望看到的东西。
When they had a large angle between the electrons and the positron, they deviated from what they expected to see.

随着正电子冷却技术的最新发展，你将1000个正电子中的999个丢弃，因此效率非常低，”Weed解释道。
With the current state of the art in positron cooling, you throw away 999 out of 1,000 positrons, so it is very inefficient," Weed explained.

可以看出这些颗粒与狄拉克电子和正电子相似，只是它们的质量接近于零。
These particles may be viewed as analogous to the Dirac electron and positron, except that their mass approaches zero.

年C.D.安德森实验发现了正电子。
In 1932 the American physicist C. Anderson discovered anti-electrons experimentally.

PET扫描（正电子发射断层扫描）仅在俄罗斯的九个城市提供，“-注意IvanTolmachov。
PET scanning(Positron Emission Tomography) is available only in nine cities in Russia,”- notes Ivan Tolmachov.

此外，正电子似乎来源于宇宙空间的各个方向，而不是某个特定方向。
Furthermore, the positrons appear to come from all directions in space, and not a single source in the sky.
