Using Lorentz transformation, a momentum vectors diagram of the emitted particle in laboratory frame and center-of-momentum frame is given in relativistic two-body reaction.
利用洛伦兹变换，画出了相对论下二体反应实验室系和动心系出射粒子动量的关系图，并利用关系图，对不同情况下的出射粒子能量分布作了讨论。
Near some sprites, the team also found radio waves in 310-mile-wide (500-kilometer-wide) bands-and these radio waves were most likely being emitted by high-speed particle beams.
该小组还在一些气辉周围发现了310英里(500公里)波段的无线电波。这些无线电波很有可能就是由高速粒子束发出的。
There is even an outside chance that this unexpected effect is brought about by a previously unknown particle emitted by the sun.
存在一种极小的可能性，即这种意想不到的效应是由一种太阳发射出的不曾被了解的粒子造成的。
Light emitted from farther away, and thus older, quasars lacked this wavelength, because the light was getting absorbed by neutral helium as well as helium with a single ion-or charged particle.
光线的发射处越远，年龄越大，类星体的光谱会缺失，因为某些波长的光线会被中性氦及氦离子或带电粒子吸收。
The group also studied particle pollution levels emitted from these sources, which are made up of a mix of tiny solid and liquid particles in the air.
这个组织同样对从这些源头释放出的颗粒污染水平进行了研究。它们由极小的固体和液体颗粒组成。
Because of the light mass, the recoil effect is strong after the particle is emitted, so the recoil effect is must taken into account to maintain the energy balance.
由于轻核质量轻，发射粒子后反冲效应很强，理论计算中还严格考虑了反冲效应的影响，从而保证了能量守恒。
An electrically charged particle, especially an electron, emitted by a conducting material at high temperatures.
一带电粒子，尤指一电子，由导电材料在高温时发射出。
