By mid-August, we had already shattered all previous records for ice extent.

& 8月中旬，我们已打破了以前的纪录，为冰的程度&。

Even more gratifying is that we have applied a combination of digital and analog technology, successfully developed an international leading level, the frequency can reach near 2MHZ, good repeatability, temperature coefficient of only 5 millionths per unit and can be long-term stability of the voltage frequency converter, which will enable new power meter can be achieved without long-term adjustment.

更可喜的是，我们已应用数字和模拟相结合的技术，成功研制出具有国际领先水平、频率可达近2MHZ，重复性好，温度系数仅每度百万分之五和能长期稳定的电压频率变换器，这将使新的电能表可做到长期不需调整。

The acceleration mobilities of rotor and fuselage subsystem and coupled system are key parameters for determining natural frequencies of the rotor/fuselage coupled system by using mobility matching method. We have deduced the analytical expressions. In order to verify the feasibilities of the expressions, it is necessary to measure those mobilities.

直升机旋翼和机身子系统以及其耦合系统的导纳是用动柔度匹配法确定直升机旋翼／机身耦合系统固有频率必要的数据，我们已推导了它们的分析表达式，为验证分析表达式的可用性，须进行试验测试与研究。

In the above example we have used im for the modifiers.

在上面的例子中，我们已用于改性即时消息。

We had reached the station at ten o'clock.

在10点钟的时候，我们已到达了车站。

We have synthesized a series of 4,4′ perfluoro-alkylated bipyridine ligands[4,4′- bis(RfCH2OCH2)-2,2′-bipyridine , Rf=HC4F8(1a), HC8F16(1b), C3F7(1c) and C10F21 (1d)] by nucleophilic substitution reactions. The reaction of fluorinated alkoxide on 4,4′-bis-2,2′-bipyridine results in the systheses of these four fluorinated ligands. These reactions are high yieldings and purification is easy. The structures are analyzed by GC-MASS、NMR、FT-IR etc.

中文摘要我们已合成出一系列在联吡啶的4，4′位置有两个氟化烷基侧链的联吡啶配位基[4，4′-bis(RfCH2OCH2)-2，2′-bipyridine ， Rf=HC4F8(1a)， HC8F16(1b)， C3F7(1c)及C10F21(1d)]，经由亲核取代反应，由4，4′-bis-2，2′-bipyridine反应而得，并具有不错的产率，其纯化也简易可行，所合成之产物并可用GC-MASS、NMR、FT-IR鉴定其化学结构。

In all these years we've made a lot of friends and met some great vocalists.

在这三年，我们已结交了很多朋友，也见了一些杰出的歌手。

Ramon Vinas, head of the civil aviation authority, said Friday."By the way it crashed we can determine there are no survivors," he said.

Gen.Ramon Vinas，民航总局负责人于星期五称&另外，我们已可判定这场事故没有生还者。&

In 1799 he resigned his tutorships, devoted himself for a couple of years to the study of philosophy and wrote some small works on education including appreciations of Pestalozzi's writings.

一种新观念的体会必须用旧有的其它观念来解释，譬如&海湾&这个词，是靠我们已有&水&、&颜色&和&声音&的旧观念来体会其含义。

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。
