查询词典 antiparticles

Itwas found that the"out-group"antiparticles of Bose type, which came into being because of CP ( charge conjugation-parity conservation) violation in the early universe and became heavier due to the phase transformation from low temperature to high temperature, are the supersymmetry companionsof the"in- group"particles of Fermi type.

研究了编内粒子和"编外"粒子的对称性，发现因宇宙早期CP破坏导致从低温到高温的相变而变重的玻色型"编外"反粒子是费米型编内粒子的超对称伴子。

However, although antiparticles can be and are created in the laboratory, this has never been done in sufficient quantity (less than one trillionth of a gram to date) to form what we would think of as antimatter.

然而，尽管反粒子可以而且已经在实验室中创造出来，却没有得到充足的质量（到目前为止所得仍小于一万亿分之一克）以形成我们所谓的反物质。

In the "indirect" process, first observed in neutral kaon particles in 1964, quantum mechanics allows particles to change into their antiparticles and back again in a process known as "mixing". In 2001, The BaBar team, working at the Stanford Linear Accelerator -- and independently the Belle collaboration at the KEK laboratory in Japan -- were the first experiments to detect this in a B meson. BaBar observed "direct" CP violation in 2004 by showing that the number of decays observed for B mesons was higher than for their antiparticle equivalents.

在&间接&过程中，量子力学允许粒子在一种被称为&混合&的过程中，在自身与其反粒子之间相互转变。1964年人们第一次在中性K介子上观测到这种现象。2001年，在斯坦福直线加速器中心工作的BaBar研究组和另一个日本高能加速器研究中心的Belle研究小组各自独立地第一次在实验中观测到这种现象发生在B介子上。2004年，BaBar小组观测到了&直接&电荷宇称不守恒，他们发现观察到的B介子的衰变数量要高于其对应的反物质。

It is in no sense a provisional theory and is largely compatible with quantum theory; it not only led to the idea of matter waves but is the origin of 'spin' and underlies the existence of the antiparticles.

这是没有意义的理论和临时主要是与量子理论兼容，它不仅导致了物质波的想法，但就是'原产地旋转'和基础的反粒子的存在。

The electric mechanism of α-cypermethrin based microemulsion formed by polyoxyethylene styrenyl phenyl ether and dodecyl benzenesulfonic salt combined with different kinds of antiparticles, and the phase behavior were investigated.

研究了结合不同反离子的十二烷基苯磺酸盐与苯乙烯苯酚聚氧乙烯醚(NR600)形成的高效氯氰菊酯微乳液的导电机理，以及反离子对体系相行为的影响。

Antimatter is matter that is composed of the antiparticles of those that constitute normal matter.

反物质是由那些常态物质构成的反粒子组成的物质。

As a consequence, the contributions of antiparticles are very small under our consideration.

还研究了反粒子的贡献，他们确实很小。

Paul Dirac's theory has been experimentally verified and today a wide range of antiparticles have been detected.

保罗·迪拉克理论已经得到实验验证，而且今天大范围的反粒子已经被发现。

Fewer than zero particles being present usually means that you have antiparticles instead.

出现比0要少的粒子通常说明了你有了反粒子。

But there is no such thing as an antiphoton (photons are their own antiparticles, and are pure energy in any case), so that cannot apply here.

但是，没有反光子这种物质（光子是他们自己的反粒子，在任何情况下，都是纯粹的能量），所以这里并不适用这一原理。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
