Counting the number of intersection points in  the diagram is a little bit trickier.

计算图中交点的数量有点棘手。

My meemaw, my professor — who's in the middle of that Venn diagram?

我的姥姥，我的教授——你们两个人的交点是谁呢？

It's where marginal--it's where the marginal cost and the demand curve intersects.

它是边成本和需求曲线的交点。

Because there are two points where the moon’s orbit crosses the sun’s plane, called nodes.

因为月球轨道太阳平面的交点有两点，称为交点。

When I do that the relevant intersection  point actually sits outside of the triangle.

当我这样做时，相关的交点实上位于三角形的外部。

The analysis showed that  the peaks of the lunar nodal cycle coincided with the cover of the mangrove canopy.

分析表明，月球交点周期的峰值红树林树冠的覆盖时间一致。

No other choice of two intersection points is guaranteed to get all the robo-ants within five minutes.

有他选择的两个交点可以保证在五分钟内得到所有的机器蚂蚁。

Now that we have a set of intersection  points on separate planes, we find whether the point is inside each corresponding triangle.

现在我们有了一组位于不同平面上的交点，我们会找到该点是否位于每个相应的三角形内。

To summarize, the force on the electron is equal to its charge, Q, times V or the electron's velocity vector crossed with B, the magnetic field vector.

总而言之，电子上所受的力等于电荷 Q 乘以 V，或电子的速度矢量磁场矢量 B 的交点。

But of course that can't happen, whether you're looking at it from one side, or looking at it from the other, those intersection points are all the same.

但当然不可能发生这种情况，无论你从一侧看，还是从另一侧看，那些交点都是一样的。

So far we have established the preliminary conclusion that the volume of employment is determined by the point of intersection of the aggregate supply function with the aggregate demand function.

至此，我们初步建立了就业量由总供给函数总需求函数的交点决定的结论。

Maybe if you're a little bit lucky,   here's one thing you might notice; every intersection point is uniquely associated  with a quadruplet of points on the exterior.

也许如果您幸运一点，您可能会注意到以下一件事：每个交点都外部的四组点唯一关联。

By correlating the active column with when voltage is received on the  input row, we can determine the exact intersection of column and row and thus which key is pressed.

通过将活动列输入行上接收到的电压关联起来，我们可以确定列和行的确切交点， 从而确定按下了哪个键。

This light is called indirect illumination, and in order to calculate it, we take the  intersection point from the primary ray and generate a secondary ray that bounces off it.

这种光被称为间接照明，为了计算它， 我们取主射线的交点并生成从该点反射的次级射线。

In September itself  there were floods, albeit minor ones, but it was only when heavy rain combined with the strength of  the lunar nodes a couple of months later that the real damage was inflicted.

九月本身就发生了洪水，尽管规模很小， 但直到几个月后大雨月交点的强度相结合才造成了真正的损害。

And we'll say that the  point where these two intersect is P. And now like, a lot of Euclid-style proofs,   we're just going to draw some new lines, figure out what things must be equal, and get some  conclusions.

我们会说这两者的交点是 P。现在就像很多欧几里得式的证明一样， 我们只是要画一些新的线，弄清楚什么东西必须相等，并得到一些结论。
