The arrest of two US citizens gave North Korea huge political capital just as its actions blasting a missile over Japan in April and detonating an atomic warhead in May were raising tensions with the international community.

这两名美国公民的被捕在当时给了朝鲜巨大的政治资本。今年4月，朝鲜向日本上空发射了一枚导弹，5月份又引爆了一枚核弹头，这些行动加剧了朝鲜与国际社会的紧张关系。

Diplomacy with nuclear-armed North Korea, which this year launched a missile over Japan and detonated an atomic warhead, hinges on the success of bilateral talks between Kim Jong-il, North Korean leader, and the US.

韩国与拥有核武器的朝鲜之间的外交关系，取决于朝鲜领导人金正日(Kim Jong-il)与美国双边谈判能否成功。朝鲜今年发射了一枚飞越日本上空的导弹，同时引爆了一枚核弹头。

The Tibetan tropopause is obviously different from the other regions at the same latitudes, c.a. 0.7 km higher in average, and the seasonal height variation of tropopause over Tibet is distinguished, in amplitude and phase, over the corresponding latitudes.

青藏高原上空对流层顶与同纬度其它地区间存在较大差异，该地区对流层顶比同纬度其它地区高约0.7 km，流层顶高度的季节变化与同纬度其它地区也明显不同，表现为振幅远大于同纬度其它地区，位相也明显不同。

The particles with higher energies can penetrate into the magnetosphere with larger distribution of the pitch angle, but only those with directions along the magnetic field lines can reach the ground.

能量越高的粒子进入到地球磁层上空的角度范围越大，但仍然只有沿着磁力线入射的粒子才能到达地球表面。

This artificially induced plasma depletion can then be used to investigate other space phenomena, such as the growth of the plasma instabilities or the modification of radio propagation paths. The 47 second OMS burn of July 29, 1985, produced the largest and most long-lived ionospheric hole to date, dumping some 830 kg of exhaust into the ionosphere at sunset. A 6 second, 68 km OMS release above Connecticut in August 1985, produced an airglow which covered over 400,000 square km.

这一人工诱导离子损耗之后能够被用于研究其他的太空现象，比如离子不稳定性的增长或者无线电传播通道的改变。1985年7月29日47秒的轨道操纵系统的燃烧产生了迄今为止最大和最长期的电离层空洞，将大约830公斤的废气在日落时倾倒入电离层。1985年8月康涅迪格上空6秒种、68公里的轨道操纵系统的排放产生了覆盖40万平方公里的气辉。

However, it was not long before five other buildings topped the Woolworth Tower.

一个新的冠军，高 1250 英尺，102 层的帝国大厦直插纽约上空。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
