The two-phase system is characterized by a single length scale, the correlation length, which is a measure of the average spacing between regions of phase 1 and phase 2. The model also assumes smooth interfaces between the phases and hence exhibits Porod behavior (I ~ Q-4) at large Q (Q*correlation length >> 1).</p> … … 5060 5061 <p style="text-align: center;" align="center"><img id="Picture 77" src="img/image183.jpg" alt="" /></p> 5061 5062 <p style="text-align: center;" align="center"><strong>Figure. 1D plot using the default values (w/200 data point).</strong></p> 5062 <p style="margin-left: 0.55in; text-indent: -0.3in;"><strong><span style="font-size: 14pt;">3.7.</span></strong><strong><span style="font-size: 7pt;"> </span></strong><strong><span style="font-size: 14pt;"> <a name="Teubner Strey"></a>Teubner Strey (Model)</span></strong></p>5063 <p style="margin-left: 0.55in; text-indent: -0.3in;"><strong><span style="font-size: 14pt;">3.7.</span></strong><strong><span style="font-size: 7pt;"> </span></strong><strong><span style="font-size: 14pt;"> <a name="TeubnerStreyModel"></a>Teubner Strey (Model)</span></strong></p> 5063 5064 <p style="margin-left: 0.25in;">This function calculates the scattered intensity of a two-component system using the Teubner-Strey model.</p> 5064 5065 <p style="margin-left: 0.25in;"><strong><span style="font-size: 14pt;"> </span></strong></p>
