Cross-References

Capture links internal to the book in a <xref> element.

Each <xref> element must have an @rid attribute which matches the @id attribute of the element being linked to. It must also contain a @ref-type attribute with the value determined by the type of element being linked to according to the table below:
Table 1. Ref-type values

Example

<p>Illustration of the principle of operation of a <italic toggle="yes">Flodex</italic> powder flowability tester. Panel
(a) shows the case of a disc possessing an orifice size <italic toggle="yes">D</italic>
<sub>
  <italic toggle="yes">a</italic>
</sub> suitably large to allow the consistent flow of material.
Panel (b) illustrates the case in which bridging, jamming or
cohesion effects [<xref ref-type="bibr" rid="bk978-0-7503-3071-8ch4bib143">143</xref><xref ref-type="bibr" rid="bk978-0-7503-3071-8ch4bib145">145</xref>]
cause the orifice to become clogged, preventing flow. If the
testing system in question possesses no intermediary sizes between
<italic toggle="yes">D</italic>
<sub>
  <italic toggle="yes">a</italic>
</sub> and <italic toggle="yes">D</italic>
<sub>
  <italic toggle="yes">b</italic>
</sub>, then a measure of flowability will be determined using
<italic toggle="yes">D</italic>
<sub>
  <italic toggle="yes">a</italic>
</sub>. Panel (c) shows an image of a real <italic toggle="yes">Flodex</italic> flow tester (reproduced with permission from
