高频

There is much high order harmonics from the inverter, so the high frequency model of the step-up transformer is established to study the influence of the stray capacitors.

同时由于变频器向该系统注入了大量的高频分量，为此建立了变压器高频分布模型，以评估变压器分布电容对全系统的影响。

After multivariable adjustment, consumption of tuna or other broiled/baked fish was associated with specific HRV components, including indices suggesting greater vagal predominance and moderated baroreceptor responses (eg, higher root mean square successive differences of normal-to-normal intervals [P=0.001]; higher normalized high-frequency power [P=0.008]; and lower low-frequency/high-frequency ratio [P=0.03]) and less erratic sinoatrial node firing (eg, lower Poincaré ratio [P=0.02] and higher short-term fractal scaling exponent [P=0.005]) but not measures of circadian fluctuations (eg, 24-hour standard deviation of normal-to-normal intervals).

经过多因素校正，鲔鱼或其他烤鱼的摄入与HRV某些特异性指标相关，包括了反映更强的迷走神经张力的指数和适当的压力感受器影响如更高的正常-正常均方根连续差[P=0.001；更大的正常化高频功率[P=0.008]；更小的低频/高频功率比［P=0.03］以及更少的窦房结电冲动游走（如，更低的Poincaré比［P=0.02］和更高的短期分形定标指数［P=0.005］），但不测量昼夜波动（如24小时正常-正常间期的标准差）。

Moreover, the protein level of pERK in the ACC was transiently increased after LTP induction, starting at 5 min and returning to basal at 1 h after tetanic stimulation.

取高频刺激后不同时间点的脑片进行免疫组化检测，结果显示，高频刺激后5 min时，pERK 表达显著升高，在10 min达到最高峰，1 h后回复到基础表达水平。

This paper analyses the wave trapper presents test methods according to the condition of actual work.

高频通道作为高频保护信号的传输通道，它能否正常的工作对于电网的安全可靠运行起着非常重要的作用。

High frequency and ultra high frequency measurements are adoptedin on-line partial discharge monitoring for power transformer.

变压器局部放电在线监测通常采用高频检测法和特高频检测法。

High Frequency and Ultra-high Frequency Financial Data is a brand new research area in financial econometrics.

金融高频数据和超高频数据的研究是金融计量学的一个全新的研究领域，研究的基本动因在于，一是对金融高频数据和超高频数据本身所具有的特征的关注，二是对理解金融市场的微观结构来说相当重要。

During ion source operating, alternating axial magnetic field and azimuthal electric field in discharge tube ionize hydrogen gas purified by hot palladium pipe, and form plasma. In fifties year, research reports studied on RF ion source are numerous however most of them are concerned about application, and research reports relevant to discharge theory or experiment model are unfrequent.

离子源工作时，放电空间交变的轴向磁场和涡漩电场激发放电管中经钯管纯化后通入的氢气电离，形成等离子体。50多年来，关于高频离子源的研究报告很多，但是，这些研究主要都集中在应用研究方面，有关高频无极环形放电离子源的理论与实验模型研究不是很多。

The curve obviously declined from the low frequency to the middle frequency section, and was reduced to zero in the high frequency section, which objectively showed the change in imaging characteristics of the eyes from the low to high frequency areas.

PSF分析系统可直接采用屈光系统MTF曲线表达人眼的成像特征，该曲线MTF值从低频至中频迅速下降，高频趋向缓和至零，定量并客观地表达了人眼成像质量从低频至高频的改变。
