光子

Producing laser photons is too expensive to make most compounds economically.

产生激光光子的费用太高，因此，不能用它很经济地制造出大多数化合物。

Highly reactive and delocalized electrons would react with photons.

高度活性和非定域的电子应该能够与光子起反应。

The two photons go off together as coherent radiation.

这两个光子一起发射出去，形成相干辐射。

Such photons will excite the higher vibrational levels of the OH molecule.

这种光子会激发OH分子的较高振动能级。

Two photons are created in the decay of the neutral pion.

双光子是在中性兀介子衰变中产生的。
