Flux looks quite different in the plane and in space because, in the plane, it is just another kind of line integral, while in space it is a surface integral.
平面中的通量和空间中的通量有很大区别，在平面中，通量仅仅是线积分的另一种形式，而在空间中，它表现为曲面积分。
But another place where this comes up, if you remember what we did in the plane, curl also came up when we tried to convert line integrals into double integrals.
除了这些，旋度还有一个用处，如果你还记得，我们讨论平面的时候,当把线积分转换成二重积分的时候。
In the line integral in the plane, you had two variables that you reduced to one by figuring out what the curve was.
在平面上的线积分中，有两个变量，可以通过了解曲线的形成规律，从而去掉一个变量。
I can move in the line, in the line in a plane.
可以沿着曲线移动，在平面内的曲线移动。
So, you see that's actually a pretty easy way of finding where a line on the plane intersects each other.

So, indeed our line could have been parallel to the plane or maybe even contained in the plane.
实际上，此时直线平行于平面，或者就在平面之上。
OK, that's what would happen if a line is in the plane.
这就是直线在平面上所发生的事情。
It's the dot product between the normal vector of a plane and the vector along the line.
这是平面法向量，和沿直线向量的点积。
Two plus t will be two and a half of five halves, So, this is where the line intersects the plane.
2 +t得到2。，这就是直线与平面的交点了。
So, let's say that we take still the same line up there, x+2y+4z=7 and let's consider the plane with the equation x+2y+4z = 7.
我们还是看之前的那条直线，同时考虑平面。
That means the line really does not hit the plane ever.
也就意味着直线不可能击中平面。
Stealth aircraft rely on shapes that prevent radar waves from bouncing back to their sources and on materials that absorb radar energy (stealth-plane time line).
隐形飞机依赖其外形来逃避雷达，这种外形能避免雷达波从机体资源上反射信号、且含有能吸收雷达能量的物质。
OK, so that's what would tell you that the line is actually parallel to the plane.
也就是说直线，实际上是平行于平面的。
Line detection algorithm based on random sample theory make the plane measurement more precise and quicker.
基于随机采样理论的直线检测算法使得平面测量更为精确、快速。
The bright horizontal line running the full length of the image is the galaxy's main disc - the plane in which the Sun and the Earth also reside.
贯穿整张图片的明亮水平线是银河系的主盘，太阳和地球就处于其中。
Surface is a kind of space can be defined three-dimensional formation, surface or plane space is the two forms of the line body.
面体是一种可以对空间进行限定的立体构成方式，曲面或平面空间是线体的两种体现形式。
Three dimensional form plane line called the line body, characteristic line body includes not only the plane all the lines, but also has its own unique form.
平面线条的三维化形式称为线体，线体不仅包含平面线全部的特征，而且的还拥有自身独特的形式。
Point, line, surface are all the factors belong to the plane constitution.
点、线、面都是属于平面构成的因素。
