Meteors in annual showers stem from comets, and the radiant point is the point in the sky where we cross the comet's orbit. It's kind of like the point in the distance where train tracks converge.
狮子座流星群的得名是由于它们流星辐射点位于狮子座。根据你所处的地理位置，狮子座一般会在凌晨1点到3点左右出现在地平线上的东北方向。
The Leonids are so named because they seem to radiate from the constellation Leo, the lion, which rises above the northeastern horizon between 1 a.m. and 3 a.m., depending on your location.

如果你连蓝牙无线耳麦也没有的话，将电话拿离耳朵稍微远一点，也会有很大的不同，辐射的强度会随着距离的拉远而迅速减少。
If a headset isn’t feasible, holding your phone just slightly away from your ear can make a big difference; the intensity of radiation diminishes sharply with distance.
热辐射密度以核爆点距离平方倒数的速度衰减，爆炸、冲击波、致电离辐射效应的衰减速度则更快。
The intensity of thermal radiation decreases only as the inverse square of the distance from a nuclear detonation, while blast, shock, and prompt ionizing radiation effects decrease more rapidly.
下午的热辐射反作用力就大于上午，因此，始终有那么点力作用于下午一侧，逐渐地就使小行星偏离轨道。
The reaction to this radiation is greater on the afternoon side than on the morning side and there is thus a small force pushing on the afternoon side that gradually distorts the asteroid's orbit.
只要将这些辐射中的百分制二点五转化成电能就可以满足一个国家在2006年的全部的能源消耗。
Converting only 2.5 percent of that radiation into electricity would match the nation's total energy consumption in 2006.
南极天文台三大观测宇宙的天文台之一，旨在检测由宇宙大爆炸而产生的大量存在于微光辐射中的扭曲现象，利用天文望远镜对宇宙射线背景进行筛选，再利用星系群的特点确定一个点，即当宇宙射线穿过极热气体时会产生轻微混乱，混乱的那一刻就是所要找的那个点。
The telescopes sift through the background cosmic radiation to find spots where it has been slightly perturbed as it passes through extremely hot gas, a hallmark characteristic of galaxy clusters.
最近的观察点是在200米以外的一个石室上，能很清楚地看到事故发生的中心，而不会让游客暴露在过高的辐射中。
The nearest observation point is 200 metres from the sarcophagus, and offers a good view of the epicenter of the accident without exposing visitors to "excessive" levels of radiation.
其中的一个方法是测量行为类似于针对某个点的单元，并记录辐射率温度读取器。
One way is to measure a cell that behaves similarly with a point and shoot emissivity temperature reader.
一点点奇思怪想可能对人有好处，但迄今为止，还没有人这样看待辐射。
A little bit of what you fancy may do you good but nobody, until now, has said that about radiation.
两点问题：太阳的微波辐射强度非常弱；更关键的是，影响微波辐射的并不是地球磁场！
Two problems: The sun is a very weak emitter of microwaves, and worse, microwaves are not affected by magnetic fields!
今天下午4点辐射将到达菲律宾。
我们是在事故发生数年之后才了解到当时核燃料融化的情况，因为那个时候反应炉的辐射才衰变至足以安全开炉的程度，这一点很重要。
It is significant that we did not learn the degree of melting until several years later, when the reactor vessel’s radioactivity had decayed sufficiently to open it.
第二点，即使不坍塌，他们说会存在辐射问题。
Second, even if it didn't collapse, they said you've got a radiation problem.
小指的是物理维度和其辐射的声波相比很小，或者其外形不会和该点声源指向性响应发生干扰。
"Small" means that the physical dimensions are small compared to the wavelength being radiated or that the shapes do not interfere with the polar response of the point source.
