1、ta analysisWe analyzed fixation duration and count and the total fixation time in regions of interest(ROIs)within the multimedia presentation.In this study,we defined ROIs as areas where there were significant differences between the decorative imagetion count,and total fixation time in each ROI for both the decorative image and non-decorative image groups.Table 1.Descriptive statistics of fixation measuresROI Group Mean Fixation Duration(ms)Standard Deviation(ms)Mean Fixation Count Standard Dev。
2、否则浆料容易凝固结块。 ()涂片大量使用可用涂布器涂布。 简单的涂布方法是将两片在玻片用肥皂水和水洗涤干净,再用碎滤纸吸干玻片上的水分,然后将其重叠在一起,用手夹住片的上端,慢慢地浸入已调好的浆液浸涂s左右(上端留一些不浸涂),然后缓慢地将载玻片从浆液中取出,要求版面均匀平滑,载片边缘上的浆料用抹布轻轻地擦去,小心将两片分开,放在磁盘中。 待浆料自然干燥后放入烘箱,在下活化,约min就制成了薄层板,取出来进行点样。 ()点样在活化好的薄层板下端约cm处的边上轻轻地用铅笔点一个标记作为起始线。 用一根内经。
