瑜伽为何要“加热”？

The village was always very quiet.The people lived there.  小题1:          

were busy working in their fields during the day ,and           小题2:           

went to bed early at night,tiring after a long day’s hard          小题3:           

work.All of them had lived in a village for all their            小题4:            

life and have never left for more than one day at a time.         小题5:           

On these days they left,they got up early in the morning.        小题6:           

They filled their carts with fruit and vegetables and sheeps,        小题7:           

and went on the market in the town beyond their valley.           小题8:           

They came back in the evening and with some money and perhaps a 小题9:            

present for their children.That was their left-hard yet            小题10:          

simple,but not unhappy.

目前对ⅡB期宫颈癌推荐的标准治疗方法是（）

腹泻患儿体重6kg，精神萎靡，呼吸深长，唇樱桃红色。COCP20vol％。纠正酸中毒，按体液总量计算，需用碱性液的mEq数是（）

A.84mEq

B.72mEq

D.36mEq

E.24mEq

如图所示K与虚线MN之间是加速电场。虚线MN与PQ之间是匀强电场，虚线PQ与荧光屏之间是匀强磁场，且MN、PQ与荧光屏三者互相平行。电场和磁场的方向如图所示。图中A点与O点的连线垂直于荧光屏。一带正电的粒子从A点离开加速电场，速度方向垂直于偏转电场方向射入偏转电场，在离开偏转电场后进入匀强磁场，最后恰好垂直地打在图中的荧光屏上。已知电场和磁场区域在竖直方向足够长，加速电场电压与偏转电场的场强关系为U=Ed/2，式中的d是偏转电场的宽度且为已知量，磁场的磁感应强度B与偏转电场的电场强度E和带电粒子离开加速电场的速度v₀关系符合表达式v₀=E/B，如图所示，试求：

（1）画出带电粒子的运动轨迹示意图；

（2）磁场的宽度L为多少？

（3）带电粒子最后在电场和磁场中总的偏转距离是多少？
