      Hello, boys and girls, please listen to me carefully. There's something important for you to remember.

It's about our geography trip. First, on Friday, we'll meet at the school gate because that's where the bus

will be. We'll start out at seven thirty, but I want you to be there at a quarter past seven, so we'll have

enough time to put the luggage on the bus. 　

      Talking of luggage, don't bring too much-we'll only be away for two nights! Just take a small bag.

That should be enough. 　

      For the project work itself, you'll need to take photos, so you can take cameras with you. You also

need a notebook, so you can write down what you find. 　

      Now we've booked into the Knellsmere Hotel, that's K-N-E-double L-S-M-E-R-E and, by the way,

they have a public phone if you want to ring your parents and don't have a mobile phone. When we stay

in the hotel, we should get back to the hotel before 9:00 p.m., so after dinner you'd better not go far away

from the hotel. In the hotel there's a gym and I know lots of you will enjoy using that. It's free for you.

Well, I wish all of you can have a wonderful time.

根据量子理论，光子具有动量，光子的动量等于光子的能量除以光速，即p=E/C，光照射到物体表面并被反射时，会对物体产生压强，这就是“光压”．光压是光的粒子性的典型表现．光压的产生机理如同气体压强：由大量的气体分子与器壁的频繁碰撞产生了持续均匀的压力，器壁在单位面积上受到的压力就是气体的压强．

①激光器发出的一束激光的功率为P，光束的横截面积为S．当该激光垂直照射在物体表面时，试计算单位时间内到达物体表面的光子的总动量．

②若该激光束被物体表面完全反射，证明其在物体表面引起的光压是2P/CS．

③设想利用太阳的光压将物体送到太阳系以外的空间去，当然只有当太阳对物体的光压超过了太阳对物体的引力才行．现如果用一种密度为1.0×10³kg/m³的物体做成的平板，它的刚性足够大，则当这种平板厚度较小时，它将能被太阳的光压送出太阳系．试估算这种平板车的厚度应小于多少？设平板处于地球绕太阳运动的公转轨道上，且平板表面所受的光压处于最大值，不考虑太阳系内其它各行星对平板的影响，已知地球公转轨道上的太阳能量为1.4×10³J/m²·s(即在单位时间内垂直辐射在单位面积上的太阳光能量)，地球绕太阳公转的加速度为5.9×10^－3m/s²．

以下是H3C无线控制器和AP间数据转发原理的有（）.

A.在无线交换机和AP之间建立IPinIP隧道，无线交换机将这些隧道看做虚拟物理端口

B.无线客户端STA的任何数据报文都将由AP通过IPinIP隧道交给无线交换机，由无线交换机统一转发

C.无线交换机从IPinIP隧道接收到用户的数据后先解隧道封装，然后做数据交换，如果出接口为隧道则对数据报文再次加上隧道封装，直到交换到最远端
