查询词典 Ac

Objective To investigate the characteristics of the AC/A ratio in children with intermittent exotropia.

目的 探讨间歇性外斜视儿童AC/A比率的特点。

Methods The AC/A ratio was measured in 142 cases of children with intermittent exotropia using a type 2001 synoptophore manufactured by the British CCAS company.

用英国CCAS公司生产的2001型同视机测量142例间歇性外斜视儿童AC/A比率，根据屈光性质和平时有无戴镜分组。

Results based on experiment and measurement data indicate that, when 244 nm argon ion laser emits 40 mW UV light, the curve of refractive index changes in single mode hydrogen loading fiber is exponential type (Ac=1.632×10-6 t 0.76912), exponential growth is obvious in the beginning, a very good linear region is following, and then refractive index increments reach saturated.

结果表明， 244 nm氩离子倍频激光器输出光功率为40 mW时，普通载氢光纤光致折射率变化量随曝光时间总体上呈现指数分布关系Ac=1.632×10-6 t 0.76912；在曝光时间较短时，造成的光栅强度较弱，光致折射率变化量有明显的指数增长趋势，之后是一段较好的线性区域，这时两个测量模型的结果得到了很好的印证，随着曝光时间的继续增加，光致折射率变化量达到饱和。

The charger automatically compensates for low AC line voltage or extension cord use.

充电器自动补偿低交流线路电压或延长线使用。

It operates on standard AC power, or you can GO cord-free with industry-standard Anton-Bauer field battery packs.

它运行于AC电源标准，或者您也可以使用工业标准的Anton-Bauer电池盒。

Permanent magnet synchronous motors have been widely used as AC drives over the last two decades due to their high efficiency, high power density and no dc field winding in the rotor. It is well known motion control of PMSM requires accurate position and velocity signals to realize field orientation.

永磁同步电动机由于无需励磁电流、运行效率和功率密度都很高，在过去的二十年里已被广泛地应用在交流调速传动中，但它的高性能控制需要精确的转子位置和速度信号去实现磁场定向。

In new structure, magnetic field in winding window area is distributed more uniform than that of simple lumped air-gap structure, resulting in reduction of AC winding loss greatly.

新结构通过在开集中气隙的高磁导率磁芯柱与线圈间加入低磁导率磁材料，为电感器的磁压分布构造一辅助磁路，进而使电感器线圈窗口内的磁场分布均匀化，大大减小了线圈涡流损耗。

The system can be widely used in belt weighing and batching process control,etc.
