查询词典 gammar radiation

The Cherenkov radiation is caused by an electron moving faster than the speed of light in a medium, such as gas.

Cherenkov辐射是由速度超过介质内光速的电子在介质里运动所产生。

Cherenkov radiation in a plasma-filled dielectric coaxial waveguide.

填充等离子体的介质同轴波导中的切伦科夫辐射。

Eight UNSC ships dropped from Slipstream space into black interstellar vacuum and there was a fireworks show of blue Cherenkov radiation and spiraling subatomic particle decays.

八艘UNSC飞船从跃迁断层空间跳入黑暗的星际真空，形成了蓝色切伦科夫辐射光和螺旋形的亚原子粒子衰减。

It was clear that the Cherenkov radiation is result of the coupling between the slow TM mode propagated along the waveguide and the negative-energy space-charge mode propagated along the beam, and the coupling strength is proportional to the beam density.

分析结果表明：切伦科夫辐射是由沿介质同轴波导传播的慢波与沿薄环形相对论电子注传播的负能空间电荷波耦合所致，且其耦合强度与电子注的密度成正比；输出频率和波增长率随着填充等离子体密度的增大而提高；保持一定的输出频率，增大电子注的束流可得到高的微波输出功率。

Meanwhile Pierre Colin of the Max Planck Institute for Physics in Munich and his colleagues reckon that the shadow of the moon could be used to help work out whether the abundance of positrons actually does come from annihilating dark matter, using telescopes that look for Cherenkov radiation —flashes of light in the sky—that are created when cosmic rays, in the form of high-energy electrons and positrons, hit the upper atmosphere.

同时，在慕尼黑的马普物理研究所的皮埃尔·科林和他的同事们指出：可以用望远镜观测月球阴影下的切伦科夫辐射现象来判断大量的正电子是否的确来自湮灭的暗物质。切伦科夫辐射现象，是指带有高能量的电子和正电子的宇宙射线，撞击外层大气层时在天空中产生的闪光现象。

They were going to remain stealthed, no matter what the cost, and fissile materials exiting Slipspace lit up with Cherenkov radiation—a signal flare to any Covenant ship within light-minutes.

他们要保持秘密行动，不论付出什么代价，分裂物质在离开断层空间时会由于切伦科夫射线闪烁——任何有光记录仪的圣约人飞船都能发现信号一样的闪光。

"Explorer 1, the first satellite sent into orbit by the U.S., discover ed the innermost Van Allen radiation belt."

探险家1号」是美国第一枚进入太空轨道的卫星，它发现了最内层的范艾伦辐射带。

The measurements made by Van Allen's experiment led to an unexpected and startling discovery -- an earth-encircling belt of high energy electrons and ions trapped in the magnetosphere now known as the Van Allen Radiation Belt.

Van Allen的实验测得的结果找到了意想不到、令人吃惊的发现—在地球磁气圈外截流了一条环绕地球的高能电子和离子环，现在被称为 Van Allen辐射带。

Characteristics of return strokes in Hefei Area measured by a VLF/VHF radiation recording system is presented.

根据观测资料，分析了利用闪电辐射场信号大容量采集系统观测到的合肥地区地闪回击特征。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
