1.希腊字母表的第八个字母
1.the eighth letter of the Greek alphabet, represented in the English alphabet as "th"
1.And then, you would be looking at a piece of that spherical shell corresponding to small values of phi and theta.
然后在这个夹壳中找出一小块，它跟φ和θ有关。
2.If an anti-Y particle collided with a proton, said proton would turn into a theta particle and a kaon.
如果用一个反”Y“粒子碰撞一个质子，该质子将衰变成一个”θ“粒子和一个K中介子。
3.So, I cannot ask myself just how will it change if I change theta and do random things with a and b?
因此我无法提问下面这样的问题，如果我改变θ，同时对于a和b做随机的改变，它会怎样变化？
4.Of course, r goes all around the z axis, but I'm just doing a slice through one of these vertical half planes, fixing the value of theta.
当然，r可以围绕z轴转圈，但我只做了一个垂直的半平面，对于一个确定的θ来说。
5.So, it is possible to treat -1 as a constant input whose weight, theta, is adjusted in learning, or, to use the technical term, training.
所以，我们可以把-1看成一个常量输入，它的权系数theta在学习（或者用技术术语，称为培训）的过程中进行调整。
6.Well, let's look at a small piece of our cylinder corresponding to a small angle delta theta and a small height delta z.
考虑圆柱表面的一个小块，它由一个极小的角δθ，和一个极小的高度δz表示。
7.Well, you could call that the rate of change of theta with respect to theta with a constant.
你可以称之为，保持a不变，θ关于θ自身的变化率。
8.What you will do is you will look for a given theta what are the bounds of r to be in the region.
你要做的是，在给定θ的情况下，找出这个区域r的上下限是什么。
9.And, because the equation does not involve theta, it's all the same if I rotate my vertical plane around the z axis.
由于等式没有包含θ，所以可以任意旋转这个垂直平面，绕着z轴。
10.And of course, if you remember what x and y were in terms of r and theta, you can also keep doing this to figure out, oops.
如果你记得x、y对r、φ的转化方式，就可以继续往下了。
