粒子

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

粒子少于零通常意味着这里存在着反粒子。

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

粒子少於零通常意味著这里存在著反粒子。

The energy can appear directly as gamma rays or can convert back to particles and antiparticles

湮没时会有γ射线从碰撞处辐射出来或还原为粒子与反粒子。

A similar visualization works for CPT violation, but in this case the effects occur because particles and antiparticles have different couplings to the background fields.

同样的具象化也可运用在CPT违逆上，在此情形下，粒子与反粒子对于背景场有不同的耦合作用。

Antiparticles are created elsewhere in the universe where there are high-energy particle collisions, such as in the center of our galaxy, but none have been detected that are residual from the Big Bang, as most normal matter is [1] (http://science.nasa.gov/headlines/y2000/ast29may_1m.htm).

有高能粒子碰撞的宇宙其它地方产生了反粒子，例如在我们的银河中心，但是没有发现来自大爆炸剩余物质，如大多数常态物质是[1]。

The concept in PHYSICS that forms of matter may exist composed of antiparticles, opposite in all properties to the particles which compose ordinary matter, has a special appeal to sf writers.

物理中有个概念对科幻作家有独特的吸引力：物质可以由属性与组成物质的粒子完全相反的反粒子组成。

Due to the complicated nature of the coupling processes between polar ionosphere and magnetosphere as well as thermosphere, however, here still remain lots of questions need to be further studied, such as the relationship between convection electric field and polar ionosphere, the mechanism of auroral particle precipitation, the origin of magnetospheric particles and so on.

如，极区电离层背景变化的气候学特征，对流电场与极区电离层的相互作用关系，以及极光区粒子沉降的机制和磁层粒子起源等等。

Transmissions at 0.75 and 1.65 μm can also be used to retrieve τ and re. 2. Study the impact of cloud inhomogeneity on the satellite retrieval simultaneously. Two 3D cloud fields, cumulus and stratocumulus fields are used in our study. The two cloud fields are generated with LES model and are adopted by the I3RC phase II. The BRDF at the wavelengths of 0.65 and 2.13 μm are calculated with SHDOM, and then the cloud optical thickness and effective particle radius are simultaneously retrieved using the MODIS algorithm. We studied the impact of cloud inhomogeneity on the satellite retrieval at high and medium resolutions. Some conclusions have been made, such as the BRDF abnormal phenomenon, the reverse relationship between τ and re, the clustering effect of over and under estimation in the retrieval of τ and re .

我们选用为I3RC所采用的由LES模式给出的具有明确物理属性的两个高分辨率三维云场－积云场与层积云场，利用SHDOM三维辐射传输模式来模拟卫星观测的辐射值，并采用MODIS算法进行反演，同时研究了在高分辨云场及中低分辨率云场下，云的非均匀性对反演云光学厚度及有效粒子半径的影响，并得到了云的非均匀性会造成的双向反射率异常，反演结果中光学厚度与有效粒子半径的负相关关系，高估或低估现象是成&簇&出现的等结论。

If scientists shine a single particle of light on a screen, the particle does something strange: It shows up in two places at once.

如果科学家将单个的光粒子投影在屏幕上，光粒子有奇怪的反应：它会同时在两个地方显像。

The study of strange particle production has consistently played an important role in revealing the production mechanisms in relativistic heavy-ion collisions.

奇异夸克的质量和理论预言的相变温度相当，奇异粒子的产生一直是研究相对论重离子碰撞中粒子产生机制的重要手段。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
