What is the difference between a MathType similarity symbol and a wave number?

the difference between a MathType similarity symbol and a wave number.

Many people in the editing of similar symbols, will directly click on the MathType toolbar template "relationship symbol" template, select the wave inside, but in the use of this symbol must be noted that the MathType edit window at the bottom of the status bar under the description is "operator Tilde", Obviously it doesn't mean something like that.

The correct way to edit similar symbols is as follows:

1. Click the "edit"-"caret" command in the MathType menu bar.

Select the edit-caret command in the MathType menu

2. In the caret window, set view to description, then pull the symbol panel scroll bar, find the "similar symbol" and click Insert. When we click on similar symbols, we can see that the description of the next face symbol is "similar", so this is the correct similarity symbol.

We can put the two symbols together for comparison, the direction of the two symbols is not the same, a downward bend, one is up, and the two bending degree is not the same, similar symbols of the degree of curvature is significantly larger, it is actually a horizontal s. So the two must be differentiated when using.
