物质粒子

Results show that the nanometer particles are in spherical shape, the size of particles is homogenized and controllable, no agglomeration. The particle size changes with the processing condition; the maximum particle size is in the range of 80~90 nm, and the minimum particle size is in the range of 25~30 nm. The ice performance test in indoor cloud chamber shows that the nanometer silver iodide particles as catalyst for artificial weather modification have great application prospect.

结果表明：纳米碘化银粒子成球形，粒径均匀可控，无明显团聚现象，不同工艺条件下获得的碘化银粒径不同，最大粒径范围在80~90 nm，最小粒径范围在25~30 nm，因为碘化银具有类冰结构，是最佳成冰物质，故纳米碘化银粒子作为人工影响天气催化剂具有极大的应用前景。

The Sino-Italy collaborative DAMA experiment aims to search for WIMPsusing NaI crystal detector. It has the same ultimate goal with L3＋Cosmics.

According to special relativity mass-energy relation E = mc2 (where E particles with the energy, m the particle mass, c is the speed of light) we can see the energy E and quality of material m can not be divided.

根据狭义相对论的质能关系E＝mc2（此处E粒子所具有的能量，m为粒子的质量、c为光速）可知物质的能量E与质量m是不可分的。

In the coarse size range, calcium ions were the largest, and the water extract of the coarse particles showed alkaline reaction.

结果显示：在广州大气粒子中，NO3-主要存在于粗大粒子中，而且和其他物质结合在一起；在粗大粒子中，溶液呈碱性，而且钙离子的含量最大。

For this project, in virtue of the experimental observations on the vertical vibrator,the invert torsion pendulum and the vertical pipe with capillary outlet,and by using numerical simulations of the discrete element method, the mixing and segregation of granular materials of spherical and neraly spherical shape with the different size and different density under the vertical vibration or parallel shear motion have been researched, and the relationship between the macroscopic segregation properties and the microscopic characteristics of granular materials and the outer actions has also explored. The theoretical model and method describing the mixing and segregation of granular materials is developed.

本项目通过在垂直振动台、倒扭摆、带毛细出口的竖直玻璃管等装置上进行实验观测，并采用以离散元方法为主的数值模拟，研究了具有不同粒子尺寸、密度的球形或近球形颗粒物质在具不同结构形状容器中垂直振动和剪切运动时的粒子混合和偏析情况，探索颗粒材料流的宏观偏析特性与微观特征量及外部作用间的关系，发展描述颗粒物质混合和偏析的理论模型和方法。

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。

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。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
