湮没

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。

It was found that the spectra contained two intense components and a weak one; the long lived component corresponds to the positronium.

配合时域介电谱方法用正电子湮没技术对硫酸三甘肽的铁电相变过程进行了测量，发现正电子寿命谱有两个较强的成份和一个很弱的成份，后者相应于正电子偶素，各分量在相变点附近很窄的温区出现奇异性质，对其起因作了解

The reaction kinetics of positronium o-Ps on MoNi/Al2O3 hydrotreating catalyst was studied by using the positron annihilation spectroscopy for chemical analysis.

采用化学分析正电子湮没谱技术研究正电子素在MoNi/Al2O3加氢催化剂上的反应动力学。

The correlation between the positronium annihilationmechanism to the microstructure indicates that PALS is novel useful tool to study thecalixarene and its supramolecule system.

讨论了三个o-Ps湮没成分与其结构的对应关系，并说明了当杯[8]芳烃与〓形成超分子结构后对正电子寿命的影响，由此拓展了研究超分子体系的新工具。

The relative small o-Ps lifetime (1.48—1.63ns) can beexplained by the rigidity and high packing density of molecule chain, due to theintrachain and interchain hydrogen bond interaction respectively, whereas in 〓-containing chitosan, the grafted 〓 that play a significant chemical inhibition andquenching role on positronium formation and annihilation is first observed.

CS的相对小的尺寸和较低的自由体积浓度归因于氢键作用而致分子链较为致密的堆砌，在〓-CS中首次发现了〓基团对正电子素湮没的抑制和猝灭作用，此时〓和〓不再直接对应于自由体积尺寸和浓度。

But floods occur in many other ways, heavy rains and thawing snowfall can overwhelm rivers, storm surges caused by hurricanes and tsunamis inundate the coastline, landslides and mudflows can displace large volumes of water.

然而洪水往往也会以许多其他方式发生，倾盆大雨和积雪消融能湮没河流，飓风和海啸引发的风暴会潮席卷海岸，滑坡和泥石流也会引起洪水的泛滥。

Sunking among the crowds and feeling that my existence turns not clean,not light and not lovely back.

在人群中湮没，感觉到存在又变得浑浊，凝重，不可爱起来。

The annealing behavior of double-space in the neutron irradiation Czochralski silicon is studied by Fourier transform infrared spectrometer technique and positron annihilation spectroscopy.

利用傅立叶红外吸收光谱和正电子湮没技术对快中子辐照直拉硅中的双空位(V2)的退火行为进行了研究。

The volcano has had more than 20 eruptions since 1616, the most destructive eruption of Mayon occured on February 1, 1814 when it buried the nearby town.

从1616年以来，爆发过二十多次，造成最大灾害的一次是1814年2 月1日，曾湮没了附近小镇。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
