反物质

However, a negative-energy tachyon propagating backward in time could be reinterpreted as a positive-energy tachyon propagating forward in time; some physicists think that such a reinterpretation would be the loophole through which the principle of causality might be preserved. J. Richard Gott proposed in 1973 that, after the Big Bang, a tripartite Universe may have been formed, consisting of universes of matter, ANTIMATTER and tachyons.

然而，带有负能量的超光速粒子回到过去可以重新解释为，带有正能量的超光速粒子可以传送到将来；一些物理学家认为通过这样一个重新解释可以避开因果关系法则。J·理查德·高特在1973年提出，大爆炸之后，可能形成了一个三重宇宙，分别包括物质世界，反物质世界和超光速粒子构成的世界。

Electrons and protons are forms of ordinary matter, but positrons are antimatter particles.

电子和质子构成了普通物质，但正电子是反物质粒子。

Calculations suggest that when WIMPs and antiWIMPs meet, one product will indeed be a lot of positrons.

计算也表明，当WIMP的正物质形式和反物质形式相遇时，一个很可能的结果就是产生大量的正电子。

They think they have seen an abundance of high-energy positrons, the antimatter versions of electrons, coming from space, and they speculate that this, too, is a sign of dark matter.

他们认为他们在宇宙中发现了大量高能量的正电子。正电子是电子的反物质形式。他们推测这也是暗物质存在的一个证据。

The medium of strong force is a self-trapped electron between nucleons, it can be called the hadron.

核子间的强作用力的介质是一个自闭的电子，称为强子；正物质的强子带负电荷，反物质的强子带正电荷。

This did not happen, which is why there is so much more matter than antimatter in the universe.

而这并没有发生，这就解释了为什么宇宙中物质要远远多于反物质。

Evidently, however, matter won against antimatter, otherwise we would not be here.

但是，很明显，物质战胜了反物质，否则，我们也不会有了。

Antimatter is sort of like matter's evil twin.

反物质有点像物质的一个邪恶的双胞胎兄弟。

The observed imbalance between matter and antimatter is a puzzle yet to be explained.

在物质和反物质之间观察到的不平衡仍然是一个还没有解释的难题。

In the realm of particle collisions and quantum processes, antimatter is produced as often as ordinary matter.

在粒子碰撞和量子过程中，反物质和普通物质一样，经常被产生出来。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
