1: The experimental animals in question were ten people, eight dogs and eight ferrets. 2: Dr Raichlen had them run or walk on the treadmill for 30 minutes. 3: Since running and walking speeds differ from species to species, the speed at which the treadmill moved was varied so that it raised the heart rates of the different participants to the same level. 4: Running speeds were thus set at 2.5 metres a second for people, 1.83 for dogs and 0.84 for ferrets. Walking speeds were set at 1.25 metres a second for people and 1.1 for dogs. 5: The ferrets proved too easily distracted to walk consistently on the treadmills and were thus left to sit quietly in their cages for this part of the study. 6: Each participating animal ran for one session and walked for one other, and did so on separate days, to avoid exhaustion. 7: Before and after each session, blood was drawn from each and the endocannabinoid levels in it were measured.

1:被考虑用来进行实验的动物有以下三种：十个人，八条狗和八只雪貂。2:Raichlen博士先让他们在跑步机上行走或奔跑30分钟。3:由于不同的动物速度不一，所以跑步机的传送带速度设置是以使不同动物的心率达到同一水平为依据。4:这样设置的结果便为：奔跑速度为人类2.5米/秒，狗1.83米/秒，雪貂0.84米/秒；行走速度为人类1.25米/秒，狗1.1米/秒。5:雪貂由于太易分心，没办法让它持续在跑步机上行走，所以在进行该部分实验时它们被留在了笼中静静地坐着。6:每只动物会跑一段走一段，为了避免动物们出现筋疲力尽的情况，实验是分成几天进行的。7:在实验前和试验后，动物们都会被抽血以检验其中的endocannabinoid水平。

1: In time the NU, with its 40m members, became his own power base. 2: He reformed it, as well as removing it, in 1984, from party politics, in order to focus its energies on raising the pesantren to the level of secular schools. 3: Though a deep believer in mysticism and the spirit world, secularism never offended him. 4: Selamat pagi, “Good morning”, did as well for him as the believer's assalamu alaykum; both, as he pointed out, meant “Peace be to you”. 5: He accepted the constitution's doctrine of pancasila—national unity and social justice with freedom of religion—as a useful creed for fissiparous Indonesia. 6: More surprisingly, he kept on cordial terms with Suharto, despite pushing against the strongman both as the hugely popular head of the NU and, from 1998, as leader of his own non-sectarian National Awakening party.

1:经过一段时间，有着4000万成员的伊斯兰教士联合会成了他的权力基础。2:他改革了伊斯兰教士联合会，同时也于1984年从政党政治中移出了该组织，为了使其更好地专注于将经学院提升为普通学校。3:尽管他是神秘主义和精神世界的忠实信徒，却从未觉得世俗主义有何不妥。4:四拉玛巴基的“早晨好”对他来说同信徒的穆斯林的“早安”一样，如他指出的这两者都寓意着“带给你平和”。5:他接受宪法关于“潘查拉希（五戒）”的条文——民族团结，社会公正和宗教自由——这对于四分五裂的印尼是一个有用的纲领。6:无论是担任德高望重的伊斯兰教士联合会主席，还是自1998年以来，领导其自创的非宗教性质的民族复兴党，他与铁腕人物苏哈托针锋相对，尽管如此，他与苏哈托的关系却一贯保持融洽，这更加让人出乎意料。

1: Their results, published in Environmental Pollution, show that as radiation levels in an area rose to 35 microsieverts per hour, the average number of birds dropped by almost a third compared with the areas where radiation levels were only 0.5 microsieverts per hour. 2: This makes sense: in those areas with a high level of radiation, living things would tend to die or sicken and fail to reproduce. 3: However, when researchers looked at the 14 bird species that lived in both regions, they found that the same level of radiation was associated with twice as large a drop in bird numbers in Fukushima as in Chernobyl.

1:研究结果发表在《环境污染》杂志上：在辐射水平为35毫西弗/小时的地方，鸟类平均数量比0.5毫西弗/小时的地方少了将近1/3。2:这是合情合理的：辐射水平高的地方，生物更容易生病死亡，更难繁衍后代。3:但是，当研究者比对两地共有的14种鸟类时，发现在同样的辐射水平下，福岛的鸟类下降数量几乎达到了切尔诺贝利的两倍。
