反中微子

This property, often called "helicity," serves to differentiate the neutrino from its antiparticle.

这种性质通常称为"螺旋性"，可以用来区分中微子和它的反粒子。

Each flavor has its own antineutrino or antimatter and forms from the opposite beta decay.

每一种味的中微子有与其对应的反物质——反中微子，其中相反的β衰败而来。

Based on the physics goals and the requirements of different neutrino experiments, this paper analyzed the features of the inverse beta decay reaction chain of anti-electron-neutrino used in the neutrino detection.

论文从不同类型中微子物理实验研究的目的和要求出发，分析了在中微子探测中所采用的反电子中微子反β衰变反应链模式的特性。

The neutrino was first postulated in 1930 by Wolfgang Pauli to preserve the conservation of energy, conservation of momentum, and conservation of angular momentum in beta decay—the decay of an atomic nucleus into a proton, an electron and an antineutrino.

中微子是1930年由沃尔夫冈泡利为了保持能量守恒，动量守恒和β衰变---一个原子核（那时还没有认识到是中子）衰变成一个质子、一个电子和一个反中微子的角动量守恒，。

One hypothesis is that the neutrino and antineutrino could be the same particle just measure from different inertial frames.

一个假说认为，中微子与反中微子是相同的粒子，只不过是在不同的惯性系中被检测到。

This will provide a guideline for the future development of neutrino physics, and in particular for the understanding of the absence of anti－matter in the universe.

这将对中微子物理的未来发展提供方向性指导，特别是对理解宇宙中"反物质消失之谜"具有重要意义。

There is a good chance that this outward diffusion of neutrinos and antineutrinos plays a crucial role in the supernova explosion.

中微子和反中微子的这种向外的散射很可能在超新星爆发中起着关键的作用。

To solve this problem, the paper has developed a new forced trigger technique to provide a coincident detection on both the prompt positron signal and the delayed neutron from the inversed decay.

在该实验已有的触发系统基础上添加了强制触发模块，使探测器在纯水环境中具有识别反电子中微子的反β衰变反应链的能力。

For instance, the electron neutrino is created from the change from proton to neutron while the electron antineutrino is formed from the change of a neutron to a proton.

例如，电子中微子是由质子转变成中子时产生的，儿电子反中微子则有中子转变为质子是产生。

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。
