在过去

In the past several years, liner DSP technology had made great achievement in aspects of theory and application.

Now, the FIA World Motor Sport Council is on the brink of rubber-stamping that plan--and Loeb is ready to walk away from the sport he has dominated for the past five years.

现在FIA 还在决定这项计划的边缘----勒布已经准备离开这项在过去5年他所统治的比赛。

In the past, the high frequency resonance technique is usually applied in the envelope detection for a vibration signal with amplitude modulation. When applying the Hilbert transform in the high frequency resonance technique for the envelope detection of vibration signals, the computing burden is very high. On the other hand, when applying the linear least squares analysis method, the computing burden is lower. When applying the envelope detection in the lowest vibration mode, an accelerometer with the low-pass filtering cutoff frequency at 4kHz should be choose.

在过去的研究方法中，振动讯号之振幅调变通常以高频解调分析法应用於包络讯号侦测，而高频解调方法应用希尔伯特转换的包络分析，所需要的计算量是非常的高，若以线性最小平方分析法应用於高频解调分析法中，则所需要的计算量较小，如果以最低模态来估测包络讯号时，可以适当的选取加速规来代替低通滤波器，而加速规的截止频带必须在4kHz左右。

Darwin studied evolution in the context of Charles Lyell's geology, but our present understanding of Earth history includes some critical advances made during the last half-century.

达尔文是在查尔斯·莱尔地质学的背景中研究进化，但我们目前对地球历史的了解包括一些在过去的半个世纪里取得的重大进展。

Our magnetic field is known to be rapidly declining (10% in the last 150 years), and the magnetic North pole is moving around at an accelerating pace - it has been predicted it will move from Canada to Siberia in the next 50 years.

我们的磁场是已知在过去150年来急剧下降（10％）和北磁极正在以越来越快的步伐前进-它已经预言，将从加拿大在未来50年到西伯利亚。

In the past 50 years, MAGNETO has built her leading position both in market and technology, and provided high-quality products across the world.

在过去的50多年中，MAGNETO已经树立了在世界钛阳极高端市场和技术领域的领先地位，向全球的客户提供高品质的产品及服务。

I was fed by grandma ,and grew up in so kinds of a family :parents are very rusticity ,while know much of principle of people's behave .So this family inherit lots of traditional virtue of china ,and create a family circumstance fill with good public praise to my grow up ;my parents have never been magnifico nor earned lots of money ,just kept me away from hunger by their hardworking and simple life in the past years .

我从小被姥姥一手带大，成长在这样的一个家庭：父母质朴至极，但是深谙做人的道理，因此这个家庭沿袭了中国诸多传统美德，也为我自小就赢得了一个充满良好口碑的成长环境；父母二人都没有当过大官，也没有挣过大钱，只是用他们的勤劳和朴实保证了我在过去那些年岁里的衣食无忧。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
