The new method is called welded line tangent method which forms a kinematics model for the robot operating in the bent degree based on the judgment of the tacking system.
该方法是根据焊缝跟踪系统判断焊缝的弯曲程度,确定机器人的运动学模型。
If the two level curves are tangent to each other that means they have the same tangent line. That means that the normal vectors should be parallel. Let me maybe draw a picture here.
如果两个等高线相切,说明它们的切线相同,也就是说他们的法向量应该平行,我再在这里画个图。
Show me a place where that's not true where the tangent line will be really bad.
请给我个这个原则不对的例子,也就是说切线没起到相应作用的例子。
That means that you want to pick, ultimately, a point on this-- this line is tangent to the efficient portfolio frontier with all the other assets in it.
那意味着你会最终会在这上面选一个点-,这条直线是与有效边界相切的,后者包含了所有的资产组合。
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
