阅读暗物质的一些参考

奇奇齐齐七

今天用有道词典查 neutralino,  发现一些例句蛮有用，可以加深对文章的把握，拿来分享一下~

The name is somewhat unfortunate: "neutralino " sounds much like "neutrino , " and the two particles indeed share various properties , but they are otherwise quite distinct .
中性伴子这名词多少有些不恰当，因为它的发音很像微中子（neutrino）；即便这两个粒子确实有一些共通的性质，但它们在其他方面是相当不同的。

As the name implies, the neutralino has zero charge , so it is unaffected byelectromagnetic forces (such as those involving light ).
从中性伴子的命名可知，它的电荷为零，因而它不会受到电磁力（比如光）的影响。

In fact , based on the expected neutralino mass and its low tendency to collide , the total mass in neutralinos almost exactly matches the inferred mass of dark matter in the universe .
事实上，从中性伴子预估的质量及它不易碰撞的倾向可得出：中性伴子的总质量与我们推算宇宙中暗物质的质量几乎完全相同。

Although the neutralino is heavy by normal standards , it is generally thought to be the lightest supersymmetric particle .
虽然按一般标准，中性伴子的质量很大，但它是超对称粒子中最轻的。

If so , it has to be stable : if a super particle is unstable , it must decay intotwo lighter super particles , and the neutralino is already the lightest .
这样一来，它无疑是稳定的：假如一个超对称粒子不稳定，它必然会衰变成两个更轻的超对称粒子，而中性伴子已经是最轻的了。

The hypothesized mass , stability and neutrality of the neutralino satisfy all the requirements of cold dark matter .
中性伴子的质量、稳定性和电中性满足了冷暗物质所要求的各种性质。
