Based on the mathematical theory,the mathematical models of the cooking technologyin ramie degumming are established by utilizing the 4 factors'central rotatal experimetnal de-sign of Box-Hunter and by means of electronic computer.

This paper discusses the problem of measuring high residual gum content in degummed ramie fibre by analysing the transference of ramic gum in alkali cooking process.

In this study,the influence of the tresis vulnus quantity on the gum output and the growth of trees was tested.

The causes for particle formation on the cathodic surface in copper electrolytic refine were analysed based on the experimental results and the amount of additives were optimized to be: hydrochloric acid 25 mg/L, thiourea starting with 5 6 mg/L and comsuming 73 g per ton of metallic copper, glue starting with 8 mg/L and comsuming 120 g per ton of metallic copper.

Compared with other materials and tools,glue and kalinite have attracted less attention.
