A step-up transformer with an air core; used to produce high voltages at high frequencies.

有一个空气中心的升压器；常用来在高频率中产生高电压。

The experimental characterisation is intended to point out a complete high frequency low signal model of high power IGBT modules that includes the RF voltage amplification effects.

此实验的特点在于指出了一个完整的包含了RF电压放大效应的高功率IGBT模块的高频率低信号模型。---大概就是这样，有些名词可能不太准确，楼主再参详参详。

A new mechanical structure with winch、staff and gimbal is used to develop a gyrometer test table to realize the high frequency of the operation. A "soft-measurement" is used to reach the high precision and this idea enhances the reliability too. By controlling the servo amplifier the control system is designed simply.

为了使测量双轴摇摆台实现高频率的运动，机械结构上设计采用了一种新型的曲柄、连杆、万向节机构；为保证系统的高精度和可靠性提出了&软测量&补偿方法；通过伺服放大器直接控制电机，简化了控制系统的设计。

These samples were collected along a main street across the urban area and a mountain route from foot to the top. Results demonstrate that the main magnetic minerals in the street dust are magnetite, maghaemite and haematite with some paramagnetic minerals. Plots of Mrs/Ms vs. Bcr/Bc and Xfd % vs. X ARM/SIRM indicate that the main grain size of magnetic minerals in the street dust are pseudo single domain. The results reveal that the Lanzhou city is more polluted in spring than in summer. The main pollution sources are anthropogenic activities （81.9%） and natural dust （18.1%）, especially the former. The spatial distribution of pollution is controlled by the topography and weather conditions.

结果表明，兰州市街道尘埃中磁性矿物含量较高，主要磁性矿物是铁磁矿、磁赤铁矿和赤铁矿，并伴有少量顺磁性矿物；磁性矿物粒度主要是准单畴；市区污染春季较夏季严重，春季高频率的强沙尘暴可能带来了更多的磁性矿物；兰州市污染物的沉积和分布在很大程度上受到气象条件和地形地貌格局的影响，市区每个盆地东端高于其它地区；兰州市污染以人为活动产物为主，人为活动贡献约为81.9％，其中包含交通约22.6％的贡献，自然降尘贡献约为18.1％；特殊的地形和气象条件，使得兰州市区的大气环境容量比平原城市的环境容量小得多，进而导致严重的大气污染。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
