| 1. | The athena experimenters say they still know very little about their antihydrogen atoms
雅典娜实验者说他们仍然对他们的反氢原子知之甚少。 |
| 2. | For example , any violation of the expected symmetry between hydrogen and antihydrogen would rock physics to its core
例如，任何违反氢和反氢之间对称的期望会动摇物理学的核心。 |
| 3. | Antihydrogen and hydrogen atoms should have the same properties , emitting the exact same frequencies of light , for example
反氢和氢原子应该有相同的特性,例如发出光的频率一模一样。 |
| 4. | Two international collaborations ( atrap and athena ) used these devices to produce thousands of slowly moving antihydrogen atoms in 2002
在2002年二个国际小组合作( atrap和athena )用这些装置生产数以千计慢慢移动的反氢原子。 |
| 5. | It is the goal of these collaborations to probe the energy level structure of antihydrogen to compare it with that of hydrogen as a test of the cpt theorem
探测反氢的能级结构把它与氢作比较如同一项cpt定理测试那样是这些合作的目标。 |
| 6. | They then observed the flashes of energy when the new antihydrogen atoms annihilated themselves in collisions with ordinary matter in the walls of the chamber
当新的反氢原子在房间墙壁中和平常物质碰撞湮灭它们自己的时候,然后他们观察到了能量的闪光。 |
| 7. | They say that in the spring , they hope to train a laser on the antihydrogen to make a preliminary measurement of the atom ' s spectrum so that it can be compared to regular hydrogen
他们在春天说,他们希望产生一束反氢激光制造出原子光谱的初步测量器以便它能与常态的氢相比较。 |
| 8. | While antihydrogen atoms have been glimpsed in cern experiments before , this is the first time they are being produced under circumstances that might eventually permit their detailed study , the scientists say
科学家说，虽然反氢原子以前在cern实验中被看见过,这是他们第一次在最终被允许他们详细研究情况下产生的现象。 |
| 9. | Once an antiproton and positron have joined forces , the resulting antihydrogen atom is electrically neutral and thus no longer caged by the electrical fields in the trap . " the atom drifts to where it wants to go , " said dr
一旦一个反质子和正电子具有了结合的力量,产生的反氢原子是中性的，结果在线圈中不再受电场束缚。 |
| 10. | In science fiction , antimatter , with its perfect convertibility to energy , is the ultimate rocket fuel , but the cern scientists see their antihydrogen atoms as a ticket not across the galaxy but in effect to a different mathematical universe , in which positive is negative and left is right
在科幻小说中,反物质,由于其可完全转变为能量,是终极火箭燃料,但是cern科学家除了不超出不同的数学宇宙的相互作用外认为他们的反氢原子不是一张银河入场券,在宇宙里正就是负而左就是右。 |
