Discusses the feasibility of applying "Classification Theory of Raw Silk Sampling Inspection" to tussah silk.

本文意在将《生丝抽样检验分级理论》应用于柞蚕丝领域。

On the basis of the theory, analyses and grade interval classification are conducted on the size deviation indices in the standard for water-reeled tussah silk. The precision assessment of the classification results between the new and old standards is expected to be helpful to the formulation of a State standard for water-reeled tussah silk.

The key technologies of Grid Method including grid divided in basin, impact radius of rainfall and number of reference rainfall stations have been discussed with example. The parameters of Grid Method have been selected through trial and error. Using simple random sampling to simulate the failure to collect rainfall, the relation between surface rainfall calculation error and station density, station distribution, uneven spatial distribution of rainfall has been sought.
