前言在“薄层分析中斑点面积测量方法的研究(I)”一文中,用量半径计算方法和小方格计数法量斑点面积再计算出百分含量来进行比较,二者无显著差异。为了证明量半径法对部分下端凹入斑点亦适用,我们特别用两种方法直接量出斑点面积来进行比较。 Foreword In the article “Study on the measurement method of speckle area in thin layer analysis (I)”, the calculation method of the usage radius and the area of ​​the small squares method to calculate the percentage of the speckle area are used to compare the percentages. There is no significant difference between the two. In order to prove that the gravitational radius method is also applicable to the concave spot at the bottom of the part, we use two methods to directly measure the spot area for comparison.
