Intensity profile of transmitted x-ray confirmed the location of the neck-drawing point. Obtained diffraction images had a time-resolution of several milliseconds, which still leaves a great capacity for improvement. Crystal diffraction appeared in the wide-angle x-ray images almost instantaneously about 20 ms after necking, whereas a four-point SAXS pattern appeared immediately after necking. with the elapse of time after necking, the four-point scattering pattern changed to a merridional two-point shape., Article, 先進ファイバー工学研究教育拠点研究成果報告書 11: 113-114(2005)}, title = {15-5-3 : レーザー加熱延伸による繊維構造形成過程の解析}, year = {2005} }
