| 摘要:为了解决标准匀度测试方法对试样尺寸的限制，在现有光透射匀度测试仪器的基础上，进行简单的改进，得到一种基于叠加法的匀度测试方法。两种纸样在4种尺寸条件下、并结合背景纸样，用新的测试方法进行匀度测试实验，研究了试样尺寸、纸张匀度对测试结果的影响，分析了新方法的可行性。结果表明，新方法能一定程度上代替标准测试方法的测试结果；新方法对本身匀度较差的测试纸样更加适用；改变背景纸样，新方法所测得的纸样匀度指数总体变化趋势基本一致，证明了其普适性。 |
| Abstract:In order to solve the limitation in dimension of test sample in traditional formation test, a new test method with simple improvement on the current formation test instrument, was proposed based on superposition rule. Comparing the traditional and new methods, the effects of sample dimension and paper formation of two paper sample with four dimensions on the test results were studied. The feasibility of the new method was analyzed. The results showed that the measured results of new method could replace that of traditional method in some degree, the new method applied to the paper sample with poor formation. Changing the background sample, the variation tendency of sample formation index were similar when using the new method. |
