查询词典 positronium

And look for the seminar on molecular positronium, well then, bippity, boppity, boo-- our pants are metaphorically on fire.

找分子电子偶素的讨论会，然后吡噼吡噼咘，我们就火烧屁股了。

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。

Even bellow the energy threshold for positronium formation, the laser can supply the extra energy to form a Ps atom.

对于激光辅助正电子对原子的重排反应，电子偶素的形成伴随着多光子过程发生，即使入射能量低于Ps形成阈值，辐射场可提供额外的能量形成电子偶素。

Positronium atoms,[168] synthetic Penicillin,[169] synthetic self-replicating molecules,[170] and the genetic bases for Lou Gehrig's disease and Huntington's disease were first discovered at MIT.

此外，正电子原子，人工合成盘尼西林，人工合成的自我复制分子以及鲁格里克式病，亨廷顿式病的基因根源等成果均是在麻省理工掀开了面纱。

AMOC results reveal that S parameter of three lifetime components in oxygen are all bigger than that in nitrogen atmosphere. These are probably caused by the oxygen making the spin-conversion of positronium atoms.

结合正电子寿命-动量关联谱测量结果，本工作分析了不同气氛下多孔硅样品中电子偶素湮没寿命及动量变化关系，讨论了多孔硅中电子偶素的湮没机制以及气氛对孔径计算理论模型的影响。

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。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
