在...的控制下

A parametric model of shoe last is built with commercial CAD software by using two main parameters to control the model.

在通用CAD软件环境下，建立了面向个体的鞋楦参数化模型，实现了两个主参数对整个鞋楦体的控制。

It is also hard to see how he can fulfil his promise to be a post-partisan president while he continues to give so much power to Democratic barons. Back in 1962, when he tried to rank America's presidents according to their merits, Arthur Schlesinger concluded that mediocre presidents believe in negative government, in self-subordination to the legislative power.

他要如何在不损害国会利益的前提下控制开支目前还不得而知；同样无法预料的是，他如何一边将大权交给民主党中的权贵，一边履行自己&超越党派之争&的承诺。1962年，Arthur Schelesinger在为美国的总统排定等级时曾总结道：平庸的总统对执政权持否定态度，他们会对立法权俯首称臣。

The pipelined CORDIC architecture is very suitable for FFT butterfly operation because of its high throughput and regularity, but it will consume lots of resources,this article presents an improved architecture of CORDIC pipeline,starting with the property that the FFT rotary factor is fixed but not arbitrary,and according to the mapping between the basic rotational angle of CORDIC and scale factor and the rule for transform among the scale factors.On the condition that the velocity of FFT butterfly operati...

CORDIC流水线结构因其高吞吐率及规整性，而很适合于FFT蝶形运算，但其缺点是耗资源多，本文从FFT中旋转因子固定不任意的特点出发，根据CORDIC基本旋转角度与缩放因子的对应关系和缩放因子之间的转换规律，对CORDIC流水线结构进行了改进，在蝶形运算速度不变的情况下，进一步减少所耗资源，在字长为16位的FFT中，每个旋转因子可用25位的控制序列来替代，从而使每个旋转因子的存储空间由32位减少到25位。

The designed controller can operate at fixed frequency without an internal oscillator,which has better output voltage ripple.

AOT控制保证了转换器在无需内部振荡器的条件下，工作于固定频率脉冲宽度调制模式，并改善了输出电压的纹波特性。

It is indicated that only a single resonance peak appears in the amplitude versus frequency curve without spurious resonance peaks during the procedure. The direct actuation enables to improve the tuning accuracy, weaken the possible sample damage by the tip, and enhance the atomic force microscope bandwidth and imaging rate.

研究表明，采用压电探针的直接激振方法在探针振动的幅频曲线中仅有单一谐振峰，可以避免在压电陶瓷管激振方法下由液体振动造成的寄生谐振峰，因此使用压电探针不仅提高了探针振动频率的控制精度，而且减小了针尖对样品的损坏，还提高了仪器的带宽和成像速度。

A setting sun casts a fiery glow over a crop duster spreading pesticides in a Brawley, California, field. In addition to controlling insects, bacterial diseases, and weeds, crop dusting can be used to apply fertilizers, delay fruit ripening, increase or decrease the number of fruit a plant produces, and defoliate plants to facilitate harvest.

How to effectively control sand flow in the oil wells is a key technology in sand control operations.

引言 如何在不影响油井产能的情况下有效地控制油井出砂成为防砂技术的关键。

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。
