针对《T》文所说的线计法存在忽略4.5ф以下的细颗粒,导致曲线形态畸变,提出用粗略筛折法“杂基处理”来修改线计法资料,使其与筛析资料形态符合等问题,本文分析了《T》文所示资料,通过正反两方面的对比、剖析,证明问题的产生是由于其计量方法不当,与抽样方法本身无关,线计法资料是可信赖的。粗略筛析法“杂基处理”的提出是不必要的。而且无论在理论上、方法上都存在许多问题,它是粒度计量错误基础上畸生出来的产物。因此,不宜采用。
For the “T” text line method there ignore 4.5ф below the fine particles, resulting in distortion of the curve shape, proposed a rough sieve method “miscellaneous treatment” to modify the line count method data to make it with the sieve data morphology This paper analyzes the data shown in “T”, through the comparison and analysis of the positive and negative aspects, proves that the problem is generated because of its improper measurement method, has nothing to do with the sampling method itself, the data of the line count method is reliable . Rough sieve analysis of “miscellaneous treatment” is not necessary. Moreover, there are many problems in theory and method, which are the product of abnormality based on the measurement error of granularity. Therefore, should not be used.
