您要查找的是不是：
- Plug in the AC adapter and restart your notebook. 插入交流电适配器并重新启动笔记本电脑.
- the AC in the DC 交流串入直流
- The DC and AC attenuator circuits provide ranging for the AC and DC functions. 直流和交流衰减器电路提供直流和交流功能的量程切换。
- Insert the DC coupler attached to the AC Adapter or a fully charged battery into the battery compartment. 插入电源适配器或充满电的电池。
- MHD propulsion types are classified into the AC MHD propulsion and the DC MHD propulsion by supplied magnetic field. 根据外加磁场特性的不同,磁流体推进可分为直流和交流两种方式。
- It should be noted that the DC transmission system does not contribute to the fault current flowing in the AC system5 during the AC faults. 应注意到,直流输电系统并不会增加交流系统故障时的故障电流。
- The converter units generate harmonics which flow in the AC and DC lines. 换流器单元产生的谐波会流过交流和直流线路。
- The battery chargers maintain a charge on the station batteries, which supply power to the DC system if the AC system fails. 蓄电池充电器持续对变电站蓄电池充电。若交流系统发生故障,就由直流系统供电。
- If the AC voltage at the input is large, part of this signal is rectified, producing an error in the DC signal being measured. 如果输入端的交流电压很大，其一部分信号被整流，于是在被测的直流信号中产生了误差。
- When the DC magnetic field is maintained at a fixed value,there is a good linearity between the output signal and the AC magnetic field which is below 1 kA/m. 在恒定直流磁场及调制磁场强度小于1kA/m的条件下,系统输出信号大小随调制磁场强度线性增加;

- A cloud is a mass of vapor in the sky. 云是天空中的水汽团。
- A fire was burning in the grate. 火在壁炉中燃烧着。
- F the keeping things, do spot test check usually to keep the ac in accdance with the materials as well as the all acs. 对所保管的物品，平时做到勤抽查，勤核对，保证做到帐物相符，帐帐相符。
- You didn't embarrass me in the slightest. 你一点也没让我为难。
- Through suita-bly selecting the control variables of the DC subsystem and reasonably treating the converter equations, the DC network calculation and the AC network calculation are completed independently, and so are the corresponding Lambdas. 适当地选取直流系统控制变量以及妥善处理换流器转换方程,不仅可以使直流网络方程与交流网络方程解耦,而且可以使拉格朗日乘子也相应地解耦。
- I groped for the light switch in the dark room. 我在黑暗的房间里摸索着找电灯开关。
- In power converters, unbalances generate undesirable DC ripple and non characteristical harmonics in the AC side. 在电力变换器中,不平衡会产生不希望的直流波动以及交流侧无特征的谐波。
