How to get more external page links

This sort of follows yesterdays post on page-views. This time the topic is on external page links. An external link is a site other than interfacebus that links to a particular page.

A page with low external pages linking in will receive a low page rank, and so will receive a lower amount of visits. So this is a list of a few pages with only one external page link, and that also has a page rank of zero [in most cases]. In most if not all cases the only external link pointing to the site would be the sitemap for this website.
Definition of Antenna Terms. ['P']
Definition of Radar Terms.
Engineering Acronyms. [He]
Dictionary of Terms.
Capacitor Terms.
VXI Board Manufacturers.
Data Highway.
And on and on it goes. I'm not sure why so many pages now have only one external link. I'll need to keep watching this issue.

So by listing a few of these pages here, they receive another incoming external link. Maybe some day they may even also receive a page rank. Of course if they do get a page rank than they may pass some of that page rank to another page that they point to.
