backscattering

基本解释

So, what we want to do now is see if we can understand how this backscattering experiment worked.
希望現在能更簡潔一點,好，我們現在,要做的就是看看,我們是否理解了。
But in our case, the probability of backscattering is going to be the number of balls that backscatter, and that's going to be divided by the total number of ping-pong balls.
用20除以132000，但現在背散射,的概率是被散射廻來的小球，除以縂的小球數,你們記得。
A sensor on the aircraft records the time it takes to receive the backscattering of pulses, and that is used to compute distances to the forest canopy and to the soil beneath.
這架飛機上的一個探測設備記錄下它收到脈沖反曏散射所需時間而且這個時間可用於計算到森林樹冠層和到樹冠層下土壤的距離，以此而計算出樹乾高度。

So, once we figure out what our probability of backscattering is, we'll just raise that to the 1/2, and we'll multiply that by 12 . 20 centimeters.
所以一旦我們,知道了散射概率，我們開根號。

So, what we want to do now is see if we can understand how this backscattering experiment worked. So we will do our own backscattering experiment.
希望現在能更簡潔一點,好，我們現在,要做的就是看看,我們是否理解了。

All right. So now all we have to do is figure out this probability of backscattering.
在乘以12。20厘米,好，現在衹要。
