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。

According to the variations of positronium annihilation lifetimes as a function of temperature, two secondary transition temperatures T(subscript β) and T(subscript γ) could be identified.

此外还发现，这种次级松弛转变温度随纳米蒙脱土含量的增加而增加。

The longest lifetime component in PALS results is ascribed to the annihilation of positronium in cavities of PS sample. It is found that 80% of the positrons implanted in PS film have formed positronium atoms. PALS results show that the lifetime of ortho-Positronium has small value when the sample was in oxygen gas medium compared with those in other medium.

正电子湮没寿命谱测试结果表明，样品中存在长达40ns的电子偶素湮没成分，并且进入多孔硅膜层的正电子约有80%形成电子偶素，具有非常高的电子偶素产额；在氧气气氛下，由于气体导致o-Ps发生自旋转化猝灭是使多孔硅样品中电子偶素寿命缩短的主要原因。

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。

In the 1990s the language of otherness, of 'the enemy', reintroduces into everyday German culture distubingly familar images of genocide, annihilation and dismemberment.

在20世纪90年代的差异性语言的'敌人'，重新引入到日常德国文化的种族灭绝，消灭和肢解distubingly听，说能力的图像。

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 ratio of final baryon to meson and baryon antibaryon correlation in e +e - annihilation are considered as sensitive observables to test the hadronizition models,because among the results obtainted in different popular hadronizition models,only those from JETSET event generator can fit experimental data by adjusting extra ad hoc parameters.

在e+e-→h′s反应中，末态重子介子比及重子反重子关联，在流行的强子化模型中，仅有JETSET事件发生器能通过调节专用附加参数较好拟合实验，被认为是检验强子化模型的最敏感可观察量。

Von Rauch points out that in the field of foreign policy "the change from Zhdanov's policy to that of Molotov and Vyshinsky, simply meant that a strategy of annihilation was replaced by one of attrition."

冯Rauch指出在田野的外交政策的改变Zhdanov&的政策，Vyshinsky莫洛托夫和策略，仅仅意味着毁灭的被人。&

Thus Empedocles said that a coming into existence from a non-existence, as well as a complete death and annihilation, are impossible; what we call coming into existence and death is only mixture and separation of what was mixed.

所以，恩培多柯勒认为，从非存在生成存在、全然消亡与毁灭是不可能的；我们所说的生成与死亡只不过是混合与混合东西的分离。
