Here, the distance between the line and the line is 3 times the line width. You can do the same for 3 h. But Here H refersLine width. It is not media thickness. To reduce the number of cablesCrosstalkEnsure that the line spacing is large enough. If the center distance of the line is not less than three times the line width, the line can be kept between 70%.The electric field does not interfere with each other.It is called a rule. 98% r
delegation, this method is delegated to the corresponding workflow. The workflow processes the parameters and data according to the specified steps. It is a bit similar to the template method.

It is also equivalent to the decoupling of process processing and implementation, and suddenly feels quite good.
Besides, I am confused when studying such a new technology, especially when there are not man
