The engineering of the electron - positron collider that we have completed also ranks among the world ' s most advanced technologies 我们的正负电子对撞机工程在全世界也是居于前列的。
Antimatter / matter reactions have practical applications in medical imaging , see positron emission tomography ( pet ) 反物质/物质反应在医学成像有实际应用,注意正电子放射断层摄影术( pet ) 。
The electron , for example , has negative charge , whilst its antiparticle , called the positron , has positive charge 举例说明,比如电子带负电荷,同时,它的反粒子被称作正电子?带有正电荷。
In march of this year , ipc acquired positron public safety systems , the montreal - based global provider of public safety solutions Ipc进行自主研发和生产,其系统的稳定性通常高达99 . 999 % 。
