他们利用红外线激光束捕获超冷锂原子气团，将其冷却到仅比绝对零度高亿分之十五开尔文。当逐渐增加原子间斥力时，研究人员观察到的几个现象表明气体已经变得具有强磁性。
When they gradually increased the repulsive forces between the atoms, they observed several features indicating that the gas had become ferromagnetic.
通常这种热-电转化方式是利用热电偶实现的。 热电偶由两层不同的金属构成，其中一层比另一层温度高时就在两层金属间产生电流。
The usual way to do this is with a thermocouple—a sandwich of two metals that produce a current when one side of the sandwich is hotter than the other.
而固定利率一般比同一期间到期的美国国债收益率高。
The fixed-rate element normally carries a higher yield than that of Treasury bonds with the same maturity.
研究人员在25年间对七千多名公务员进行了跟踪调查。 调查结果发现，那些称生活无聊的人在研究结束前死亡的可能性比生活愉快的人高近40%。
Of more than 7,000 civil servants who were monitored over 25 years, those who said they were bored were nearly 40 per cent more likely to have died by the end of the study than those who did not.

基于薄板的弹性稳定理论，确定了在纯弯状态下空腹受弯钢构件孔口上方腹板和孔间腹板的最大高厚比。
Based on elastic stability theory of thin plate, the maximum high-depth ratio of these two kinds of web under bending is deduced.
在厄瓜多尔下榻的饭店里，厨师间甚至展开了竞争：一名德国厨师和一名厄瓜多尔厨师在两国球队比赛尚未开始前先来了个竞争上岗—比谁的煎蛋质量高。
There's been an especially fierce rivalry in the Ecuador team hotel – where one chef's German and the other Ecuadorian! So we challenged them to make the perfect omelette.
针对萨中高台子油层进入高含水后期，区块间压力差异较大，油水井数比偏高，井网密度低，计算了合理注采井数比及井网密度，评价了目前的注采压力系统。
Having entered into the later period of high water cut in Gaotaizi reservoir, pressure difference between blocks is bigger, oil-to-water-well ratio is higher and pattern density is lower.
研究结果表明，在塑性区掘进回采巷道引起的应力转移比在高应力的弹性区掘进回采巷道引起的应力转移要小得多，减轻水采矿压显现的关键是在低应力区掘进回采巷道和实行区段间交替回采。
The research results show that the stress change caused by excavating roadways in the plastic zone is much less than that in the elastic zone with high stress. The key for reducing mining press...
