(18分)如图所示,空间存在垂直纸面向里的两个匀强磁场区域,磁感应强度大小均为B,磁场I宽为L,两磁场间的无场区域为II,宽也为L,磁场III宽度足够大。区域中两条平行光滑金属导轨间距为l,不计导轨电阻,两导体棒ab、cd的质量均为m,电阻均为r。ab棒静止在磁场I中的左边界处,cd棒静止在磁场III中的左边界处,对ab棒施加一个瞬时冲量,ab棒以速度开始向右运动。

 
 

 

(1)求ab棒开始运动时的加速度大小;

(2)若ab棒在区域I运动过程中,cd棒获得的最大速度为,求ab棒通过区域II的时间;

(3)若ab棒在尚未离开区域II之前,cd棒已停止运动,求ab棒在区域II运动的过程中产生的焦耳热。

People from East Asia tend to have more difficulty than those from Europe in   42  facial expressions – and a new report published online in Current Biology explains why.
Rachael Jack, University of Glasgow researcher, said that rather than scanning evenly (均匀地) across a face as Westerners do, Easterners   43  their attention on the eyes.
“We show that Easterners and Westerners look at different face features to read facial expressions,” Jack said. “Westerners look at the eyes and the mouth in equal measure, whereas Easterners favor the eyes and   44  the mouth.”
According to Jack and her colleagues, the discovery shows that human   45  of emotion is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used to   46  convey emotion in a cross-cultural situation.
The researchers studied cultural differences in the   47  of facial expressions by recording the eye movements of 13 Western people and 13 East Asian people while they observed pictures of   48  faces and put them into categories: happy, sad, surprised, fearful, disgusted, angry, or neutral (中立的). They compared how accurately participants read those facial expressions using their particular eye movement strategies.
It turned out that Easterners focused much greater attention on the eyes and made   49   more errors than did Westerners. “The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions,” Jack said. “Our data suggest that whereas Westerners use the whole face to convey emotion, Easterners use the eyes more and mouth less.”
In short, the data show that facial expressions are not universal signals of human emotion. From here on,   50  how cultural factors have differed in these basic social skills will help our understanding of human emotion. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.
