然而，通过光谱学测量，宇宙中氦的数量表明，宇宙中重子的数量要比基于星系光度所估计的要多得多。
However, the amount of helium in the universe, as measured by spectroscopy, suggests that there are far more baryons in the universe than estimates based on galactic luminosity indicate.
一些晶莹的雪花落在了千重子的头发上，很快就消融了。
Naeko did not look back. A few delicate snowflakes fell on Chieko's hair, then vanished.
对我们而言，重子的CP镜像对称需要被打破。“Buckley解释说。”
"For us, made of baryons, to exist, the mirror of charge-parity symmetry needs to be broken," Buckley explains.
结果表明，较高激发态的介子质量与实验符合较差，但基态重子的质量与实验符合得很好。
It is found that for mesons in their highly excited states the agreement between calculation and...

超荷一个量子量，等于一个粒子多重线谱的平均电极；或者相当于量子数和重子的数量的总和。
A quantum number equal to twice the average electric charge of a particle multiplet or equivalently to the sum of the strangeness and the baryon number.

A quantum number equal to twice the average electric charge of a particle multiplet or, equivalently, to the sum of the strangeness and the baryon number.
本文的主要目的和任务是求解基态八重态重子的光锥分布振幅，以及研究其在光锥求和规则中的应用。
The main aims of this thesis are to examine the distribution amplitudes of the octet baryons, and to investigate their applications.
这些星系可能为宇宙中长期存在的缺少重子质量这一谜题提供了答案。
These galaxies may constitute an answer to the long-standing puzzle of the missing baryonic mass in the universe.
天文学家长期以来都在推测，最终可能会在星际空间或者是在难以探测的大量星系中发现丢失的重子质量。
Astronomers have long speculated that the missing baryonic mass might eventually be discovered in intergalactic space or as some large population of galaxies that are difficult to detect.
最初的混合削减是“重子削减”。
暗物质：这一般是指“外来的”非重子物质，与普通物质只有较弱的的相互作用。
Dark matter: this generally refers to "exotic" non-baryonic matter that interacts only weakly with ordinary matter.
强子（例如由夸克组成的微粒，包括中子和质子这样的重子）只有在宇宙大爆炸发生百万分之一秒后才得以形成。
Hadrons (i.e. particles made from quarks; including baryons like neutrons and protons) were only allowed to form 10-6 seconds after the Big Bang.
这些被称为重子声学振荡的东西为测量随时间变化的宇宙的膨胀速度和对暗能量的值施加限制提供另一尺码。
These so-called baryon acoustic oscillations offer another yardstick for measuring the expansion rate of the universe over time and putting limits on the value of dark energy.
大型强子对撞机是同样道理。庞大的实验场横跨两个国家，但研究的亚原子粒子(重子和介子)却微小至极。
Such is the case with the Large Hadron Collider (LHC), an experiment so grand that it spans two countries in its quest for subatomic particles so tiny that they are literally almost nothing.
额外的收获是，“X”粒子还能解决另一个困扰已久的宇宙谜题：为什么宇宙中物质多于反物质？(物理学家称之为“重子不对称”。)
As an added bonus, an "x" particle could solve another perplexing cosmological mystery: why is there more matter than antimatter in the universe? (It's known as "baryon asymmetry" among physicists.)
布鲁克海文国家实验室的大型重子对撞机内---科学家制造宇宙最高温度的地方

科学家把这些常见物统称为“重物质”，因为质子和中子都属于亚原子结构的重子。
Scientists call ordinary matter "baryonic matter" because protons and neutrons are subatomic particles called baryons.
在过去的几年，中国全钢载重子午线轮胎的需求量和产能都快速的增长，行业景气度非常高。
During the past several years, the demand and supply of All Steel Radials Tire in China market increased very quickly.
在标准模型中重子数是绝对守恒的。
The baryon numbers are absolutely conserved in the Standard Model.
而大统一理论则预言在原子核中的核子将衰变，重子数守恒将被破坏。
However, the nucleons in nucleus will decay and baryon-number conservation may not be absolute according to the Grand unified theory.
结果显示，非重子暗物质背景的存在将对引力系统的不稳定性产生重要影响。
The results show that the existence of non-baryonic dark matter background influences seriousely the instability of a gravitational system.
所有与中子、质子放在一起的粒子统称为重子。
All particles which are together with the neutrons and protons are called baryons.
所有与中子、质子放在一起的粒子统称为重子。
