查询词典 Ac

First, it discusses the impact of the number of dimensions on rating results and the four meta-dimensions in AC. Second, it introduces the indexes of rating accuracy in AC and expounds different types of rater training programs and their impact on rating accuracy. Third, although AC has proved good criterion-related validity, the research on its construct validity has not yet reached an agreement.

There are no sufficient holes to follow the negative AC bias stress when high frequency is chosen. Due to the operation of the flat panel displays is under AC signal, therefore we discuss the degradation under DC and AC bias stress which include positive and negative bias stress on gate and drain of TFTs. What's more, we discuss asynchronous gate and drain bias stress on TFTs, and study the degradation mechanisms.

因为实际面板在运作时就是闸极与汲极采用交流方式操作，所以接著探讨在闸极上与汲极上给予直流正、负偏压与交流正、负偏压应力测试，来比较非晶矽薄膜电晶体在闸极与汲极分别有偏压下，电晶体的最大衰退变化量，再加上闸极与汲极给予非同步偏压的状况，探讨此一非同步状况对於电晶体的影响，以及了解是哪些机制造成如此差异。

AC:ac coupling,block the DC signal of input signal only AC signal pass into attenuator.

AC：交流耦合，阻断输入信号的直流信号，只有交流信号通入衰减器。

Four sorts of sex pheromones that were mixed at different ratios with three kinds of main sex pheromone components of seabuckthorn carpenter moth:-7-tetradecenyl acetate (Z7-14:Ac),-3-tetradecenyl acetate (E3-14:Ac) and-7-tetradecenyl acetate (E7-14:Ac), were experimented in the field. The results showed that four kinds of pheromones all had strong, attractive effects on male moths.

为比较沙棘木蠹蛾性信息素不同配方的诱集效果，该文利用人工合成的性信息素组分顺-7-十四碳烯乙酸酯(Z7-14：Ac)、反-3-十四碳烯乙酸酯(E3-14：Ac)和反-7-十四碳烯乙酸酯(E7-14：Ac)按照不同比例配置的4种配方进行了野外诱集试验。

Now the company's main business has: AC-DC, AC-AC, voltage converters, choke, inductor coil, filters, transformers, power transformers, all types of special transformers, the total frequency, high-frequency transformers and various types of switching power supply, etc.; and in the domestic set up a sound distribution network of electronic components.

现公司的主要经营项目有：AC-DC 、 AC-AC，电压转换器、扼流圈、电感线圈、滤波器、互感器、电源变压器、各类特种变压器，共频、高频变压器及各类开关电源等；并在国内建立了完善的电子元器件分销网络。

The term AC electrokinetics refers to the movement of particles using AC electric fields. An AC field induces a frequency-dependent dipole on a polarizable particle. The interaction of this dipole and a non-uniform field can give rise to dielectrophoresis.

根据电动力学理论，当施加一交流电场时，可使其中可极化粒子产生出一与频率相关的电双极，藉由与周围介质在非均匀电场下交互作用，可产生介电泳现象。

Measurement of conducted emissions on cabinets containing multiple items of equipment Where the EUT is a cabinet or rack that contains multiple items of equipment that are powered from an AC power distribution strip and where the AC power distribution strip is an integral part of the EUT as declared by the manufacturer, the AC power line conducted emissions should be measured on the input cable of power distribution strip that leaves the cabinet or rack, not the power cables from the individual items of equipment.

当EUT为包含多台设备的机柜或机架且这些设备通过一个交流电源接线板供电，且制造商申明该交流电源接线板为EUT的一个部分时，其交流电源传导发射的测量应在离开机柜或机架的交流电源接线板输入电缆上进行，无需对每台设备的交流电源分别进行。

All iliac hone graft fused well and a great deal of bony callus was found the vertebral body surface. Lucency area was in seen surrounding the hone graft, titanium and AC-AFF on the X-ray films, and there wan new bone formation in the interface of internal union and bone. The central region of titanium and AC-AFF became vague and new bone formation was found in the intracavitary aim of implants by CT scan. And port of the new hone transited the parietal reticulation and connected with normal ones at titanium and AC-AFF.

髂骨植骨组融合情况良好，融合界面上有较多的骨痂生成。X线摄片见植骨块、钛网、AC-AFF中空区域模糊且有骨组织生长，内植物周围无透光带存在，植骨界面上有骨桥形成；CT扫描在钛网及AC-AFF组可见内植物腔内形成的新骨通过其四壁的网眼结构与周围骨质相接，说明所有标本均达到骨性融合，但其中以AC-AFF组形成的新骨数量为多，且较为成熟。
