It can fire off only the events that were registered by the current process. This design pattern illustrates these two points.
它可以只释放出当前进程所注册的事件。
Now there many ways I can connect these two points together. The simplest way is to draw a straight line. It's called the linear interpolation. My line is not so straight, right here. You could do a different kind of line.
最简单的办法是,像这样画一条直线,这叫线性插值,不过我的这条线画得不太直,你也可以用别的办法,比如一条抛物线。
So let's reflect these two points.
那我们就把这两个点对称过去
I don't know how well you can see it in this figure here, is the slope of a straight line connecting these two points, and as the points come closer and closer, the straight line would become tangent to the curve.
我不清楚你们对于这个图像的理解,这条连接两点的斜线,随着两点距离逐渐缩小,两点连线会变成曲线的切线
