Ok, I think I understand a little better, but when you say you "can't see" the equations, surely you don't mean they are totally invisible, right? Because that's what "can't see" means. (I realize English isn't your first language, so I'm not bashing you for that; I'm just saying that's the reason for our miscommunication.)
Here's what I see when I insert a "display equation" (i.e., an equation in its own paragraph) directly beneath paragraph 4; I'm assuming you're seeing something similar:

This is a fairly common occurrence in Word -- the page/template designer sets the paragraph leading (the vertical distance from one line in a paragraph to the other) to an exact point value, rather than simply
Single, which is the default. In your template, for example, whoever designed the template set the paragraph line spacing to be 12.2pt -- which is normal for 10pt text, which the template uses. The trouble comes when you put something larger than 10pt -- an equation for example -- into the paragraph or into a new paragraph.
The way around this is to leave the paragraph spacing set to this value except for paragraphs where it cuts off part of the equation. To change it, in the Paragraph group of the Home tab, click the "dialog box launcher" (that's the small triangle in the lower-right corner of some groups). This will bring up the Paragraph dialog. You'll notice in the Spacing section, the
Line spacing is set to
Exactly 12.2pt. Change this to
At least 12pt (setting it to Single will probably work just as well). Click OK and you're on your way. You
can do this for every paragraph that uses the Normal style, but that will probably make a change the journal doesn't want, so it's best to just change the paragraphs you need to. (BTW, these instructions are for Word 2010, and may vary slightly for other versions, but the same basic procedure will work in any version of Word.)
Here's the same paragraph & equation with spacing set to "At least 12pt":

Thanks so much. My problem is solved. As you said, my first language is not English. I am sorry for my poor English. I am trying to be stronger in English.
