Which we are unable to attend, because we're going to a symposium on molecular positronium given by Dr. Emil Farmanfarmian.

我们去不了因为我们要去参加有关分子电子偶素的学术研讨会，研讨会将由 Emil Farmanfarmian 博士主讲。

It has been known for many years that an electron and its antiparticle, the positron, may together form a metastable hydrogen-like atom, known as positronium or Ps ref.

多年前科学家就已经知道，一个电子和它的反粒子，即正电子，能够结合形成一个亚稳态的、像氢原子一样的原子，被称为positronium。

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

It has been known for many years that an electron and its antiparticle, the positron, may together form a metastable hydrogen-like atom, known as positronium or Ps ref.

多年前科学家就已经知道，1个电子和它的反粒子，即正电子，能够结合形成1个亚稳态的、像氢原子1样的原子，被称为positronium。

It has been known for many years that an electron and its antiparticle, the positron, may together form a metastable hydrogen-like atom, known as positronium or Ps ref.

核心提示：多年前科学家就已经知道，1个电子和它的反粒子，即正电子，能够结合形成1个亚稳态的、像氢原子1样的原子，被称为positronium。

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 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 labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
