Based on the standard blast-wave model, we study some aspects of afterglows, including the jet effect, reverse-shock radiation, early afterglows of short bursts, and neutrino emissions in afterglows, etc.

基于标准的冲击波模型，本论文就余辉的各个方面进行了研究，包括喷流效应、反向激波辐射、短暴早期余辉和余辉中的中微子辐射。

Analogously, putting these changing regular time after time to the known transformation of various elemental particles from electron and positron to neutrino, to various meson, to various hyperon, to proton, to neutron, to various atom, can all be agree well with actual observation results.

类似地，将这种变换规律逐次用于已知的，由电子、正电子到中微子，到各种介子，到各种超子，到质子，到中子，到各种原子的，各种基本粒子的转化情况，都能与实际观测结果很好地相符。

It turns out that the 3×3 neutrino mixing matrix V, which appears in the leptonic charged-current weak interactions, must not be exactly unitary.

结果表明，在轻子带电弱流中出现的3×3中微子混合矩阵V必须不是严格幺正的。

But the relatively low-energy muons produced in the atmosphere can travel only a few kilometres. So by building neutrino arrays like ANTARES and IceCube deep under water or ice, astronomers can make sure that most of the muons they detect were actually produced by cosmic neutrinos.

在大气层中产生的能量较低的μ介子穿梭距离只有几公里，也就是说，制造类似&心宿二&和&冰块&这样深埋水下或冰层下的中微子望远镜阵列，能够确定探测到的绝大多数μ介子是否由宇宙中微子产生。

For the first time, we investigated the possibility of using non-minimal coupled scalar field (include Real and Complex scalar fields) as the candidate of dark energy---Quintessence or Phantom. A cosmological model droved by real scalar field with accelerating and decelerating, forever cycling and expanding was constructed. Classical and quantum wormholes with Tachyon fields were discussed in detail. The entropy of sphere symmetric black holes due to arbitrary spin fields was studied, and the proportional relations between entropy and fields degeneracy was derived. For the first time, we investigated the neutrino quasinormal modes of stationary black holes in the background of de Sitter space-time, and the quasinormal modes of Schwarzschild black holes with arbitrary spin fields. We also studied the quantum teleportation in the background of curved space-time for the first time.

中文摘要：我们首次研究了非最小耦合标量场作为宇宙暗能量－Quintessence、Phantom的可能性；构造了一个实标量场驱动的加速－减速无限循环，永恒膨胀的宇宙模型；详尽讨论了具有Tachyon场的经典和量子虫洞；研究了一般球对称黑洞缘于任意自旋量子场的熵，给出了熵与量子场简并度之间的正比关系；首次研究了deSitter背景时空下具有中微子场的稳态黑洞的似正规模与具有任意自旋场的Schwarzschild黑洞的似正规模问题；首次研究了弯曲时空背景下的量子通讯问题。

No apparatus can detect neutrinos unless it is extremely massive, because great mass is synonymous with huge numbers of nucleons, and the more massive the detector, the greater the probability of one of its nucleon's reacting with a neutrino.

没有仪器可探测到中子除非它非常之大，巨大的同时会产生很多合子，探测器越大，其合子同中子发生反应的几率也就越大。

In July 2000, Fermilab experimenters announced the first direct observation of the tau neutrino, the last fundamental particle to be observed.

2000年7月，费米实验室的实验宣布首次直接观测中微子的头，最后基本粒子待观察。

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。

The goal of the Dayabay reac-or antineutrino experiment is to determine the unknown mixing angle13 with a sensitivity of 0.01 or better in sin2θ13, an order of magnitudeetter than the current experimental limit.he detection mechanism is to detect both positron and neu-ron generated from inverse β decay of anti-neutrino.

大亚湾的目标是想要找出比现今已知的实验数据更精确的测量。探测机制是利用反微中子造成的反衰变中的正子与中子。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
