| 1. | A historical review of einstein ' s introduction of cosmological constant
爱因斯坦引入宇宙常数的历史评述 |
| 2. | Traditional energy - momentum pseudotensors revisited with a cosmological constant
宇宙常数模型中传统能动量赝张量的修正 |
| 3. | In this recipe , the constant ' s density was half that of matter
为了达到这个目的，宇宙常数的能量密度必须是物质密度的1 / 2 。 |
| 4. | Both the cosmological constant and quintessence fall into the general category of dark energy
不管是宇宙常数还是第五元素，都属于暗能量的?畴。 |
| 5. | But its value could be explained if the universe was much , much older than most experts believe
但如果宇宙比专家所估算的还要老很多很多的话，宇宙常数的存在就足以影响了。 |
| 6. | In these contexts , the fields work because they are the simplest generalization of einstein ' s cosmological constant
在这样的情况下，由于纯量场是爱因斯坦宇宙常数最简化的归纳，因此它会产生作用。 |
| 7. | String theory , which unites gravity with quantum mechanics , offered the hope of explaining the attenuated cosmological constant
统合重力及量子力学的弦论，似乎能为微小的宇宙常数提供一个合理解释。 |
| 8. | But to produce the observed acceleration of the universe , the constant ' s density would have to be twice that of matter
但若想造成现今观测到的加速膨胀，则这个宇宙常数的能量密度须为物质密度的两倍。 |
| 9. | This finding revealed that cosmological constant factor cannot be neglected . it represents a repelling force , which fuels the universe s expansion
这个发现显示宇宙常数不但不可忽略，它还造成一个排斥力，促使宇宙加速膨胀。 |
| 10. | In principle , physicists might like to examine one or a few vacua having the right cosmological constant to see if they offer testable predictions
原则上，物理学家会想挑几个有正确宇宙常数的真空来检验，看看它们是否做得出可试验的预测。 |
