Should that prove successful, it'll be followed later by a joint mission with humans -- that is, if the robots don't find a way to take over before then and deny the spacemen their planetary visas.

拥有一个扩大器、2个扬声器，一个Line输入，可以用来输入其他音频设备，当然还配有可以在雪崩状态发射求救型号的装置（这个酷，不过听iPod时会发现雪崩来袭吗？），售价200美元（约新台币6，700元）。

I used about 6 years with a couple of TDL Nucleus 1 Loudspeakers to amplify a computer soundcard with great success.

In addition to 9 realistic guitar sounds, there are 8 bass guitar sounds, banjo, shamisen and grand piano.

此外该吉他内置有扬声器同时附带耳机接口，可用于连接外置放大器。

Carbon nanotubes, it turns out, can be used to make paper-thin loudspeakers.

碳纳米管，它的出现，能用来制造像纸一样薄的扬声器。

Software acts as a virtual user, remotely controlling and operating the devices, pressings keys using electrical signals, listening to ringers and speakers using audio capture and streaming, and viewing displays using video capture and streaming.

软件作为一个虚拟的用户，进行远程控制和操作设备， pressings键使用电信号，听林格和扬声器使用音频捕捉和分流教育，并观看显示器用视频捕捉和流媒体。

The monitor EDGE15CXPB is a highly efficient 2 way low profile system. The bass frequencies are reproduced by a high excursion 15" woofer with a 4" voice coil. The woofer is equipped with a copper ring on the pole piece to achieve the lowest distortion in the critical vocal range.

EDGE15CXPB 是一个高效率的二分频紧凑型多功能返送扬声器，低频采用15英寸远射程单元配备 4 英寸音圈，这种低频单元在中心极上装配有铜圈，可将语音频段的失真降到最低。

Lead al oys as solder for transducers used in high-powered (designated to operate for several hours at acoustic power levels of 125 dB SPL and above) loudspeakers.

用作大功率扬声器（用在长时间操作125分贝以上的音响系统）的传感器中焊料的铅合斤。

At one moment, it might appear to be 6 ohms, and a moment later, it might appear to be 40 ohms.

而扬声器运动的时候，其实际阻抗就会发生变化。在某一时刻，它可能是6欧，而在另一时刻，就变成40欧。

Microcontroller through the infrared sensor part and the voice-activated sensor part of the coming changes in the signal to determine whether there are outsiders, if sent through the speakers or the diode to the police; infrared sensors, infrared emission through the launch tube to the receiving tube, two between elements of a connecting via infrared, when there are objects stand in the middle, they then pass on the changes in level microcontroller; Similarly, voice-activated sensor is converted into electrical signals into acoustic signals and then transmitted to the microcontroller; keyboard is used to set the alarm trigger conditions.

单片机通过红外传感部分和声控传感部分的传来的信号的变化来判断是否有外来者，如有则通过扬声器或者发给二极管来报警；红外传感器是通过发射管发射红外线到接收管，两个元件之间通过红外线进行连接，当有物体挡在中间时，便把电平的变化传给单片机；同理，声控传感器是把声音信号转换为电信号然后传送给单片机；键盘是用来设置报警触发的条件。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
