Scientists explain all of these manifestations of the arrow of time in terms of entropy—loosely, the “disorderliness” of a system.

时间箭头只能说明时间的方向性，它不能说明时间是直线的或一定指向未来。
But the particular aspect of time that I'm interested in is the arrow of time: the fact that the past is different from the future.
但是关于时间我感兴趣的一个方面是时间之箭：即过去与未来不同这一事实。
"Perhaps life clings to these patches where entropy is going up, since we need the arrow of time to exist," UC Davis's Albrecht said.
“也许生命需要熵值上升的这些地方，因为我们需要时光之矢存在，”加州大学戴维斯分校的阿尔·布雷特说。
To return to the arrow of time, there remains the question: why do we observe that the thermodynamic and cosmological arrows point in the same direction?
回头再说时间箭头，余下的问题是；为何我们观察到热力学和宇宙学箭头指向同一方向？
So inside those new universes, which move forward with the arrow of time, there are places where the laws of physics are different —anomalies in spacetime.
那些新产生的、沿着时间之箭前进的不同小宇宙里，存在物理定律不同的地方，比如时空异常。
So inside those new universes, which move forward with the arrow of time, there are places where the laws of physics are different — anomalies in spacetime.
那些新产生的、沿着时间之箭前进的不同小宇宙里，存在物理定律不同的地方，比如时空异常。
So if the arrow of time is based on our consciousness and our ability to perceive it, then do people like you who understand it more fully experience time differently then the rest of us?
如果时间之箭是基于我们的意识和感知它的能力，那么像你这样更充分地理解它的人与我们其他人相比是否有不同的时间体验？
The nub of the problem is that you cannot have a consistent “arrow of time” in the presence of closed timelike curves.
问题的关键在于在封闭的时间型曲线中没有一个连续一致的“时间箭头”。
To the right there's a drawing of Earth orbiting the Sun, with an arrow pointing to the right. The arrow means one year, the time of it takes the Earth to rotate around the Sun.
一个箭头指向球体右方，那儿有一个地球围绕太阳旋转的图样，这个箭头意味着一年，暗示地球围绕太阳旋转一圈的时间。
Another exception is the "cosmological arrow of time," which points forward from the Big Bang in the direction of the universe's expansion.
另一个例外是“时间的宇宙箭头”，该箭头从大爆炸指向宇宙膨胀的方向，其可能与热力学箭头相连，指向宇宙最终的热寂。
The apparent arrow of time emerges as a property of the macroscopic system, but it's not there in the laws that govern the individual particle interactions.
很显然时间箭头成为了宏观系统的一种性质，但没有定律来控制单个原子间的相互作用。
In that time when it's changing, there's an arrow of time, but once you reach equilibrium, then the arrow ceases to exist.
但一旦你达到均衡点时，那么时间之箭将停止存在。
The next time you want to run the project, click the arrow next to Run, as shown in Figure 7 and select the configuration with the name of your class containing the main method.
下一次需要运行项目时，单击Run旁边的箭头，如图7 所示并选择带有包???main 方法的类名的配置。
So that static universe in the middle has time as a coordinate but there's no arrow of time.
所以这个处于中间的静止的多元宇宙具有作为坐标的时间，但是没有时间之箭。
This serves as a crude model of entropy, Smolyaninov says, representing the thermodynamic arrow of time.
可以看作是熵的粗糙模型，斯莫连尼诺乌说，它代表了热力学时间之箭。
Time has three kinds of paces: the future comes slowly, the present is flying like an arrow, the past never stands still.
时间有三种步伐：未来姗姗来迟，现在象箭一样飞逝，过去永远静止不动。 翍——席勒。
There are three paces of time: the future long overdue, the present is flying like an arrow, the past never stand still.
时间的步伐有三种：未来姗姗来迟，现在象箭一般飞逝，过去永远静立不动。
There are three paces of time: the future is like an arrow flies be long in coming, now, the past is always at a standstill. - Schiller.
时间的步伐有三种：未来姗姗来迟，现在像箭一样飞逝，过去永远静立不动。--席勒。
The universe would be in a state of almost complete disorder. There would be no strong thermodynamic arrow of time.
宇宙将处于几乎完全无序的状态，这时就不会有强的热力学时间箭头。
The universe would be in a state of almost complete disorder. There would be no strong thermodynamic arrow of time.
宇宙将处于几乎完全无序的状态，这时就不会有强的热力学时间箭头。
