通过仪器分析和数理统计表明 ,丝胶的胶粘特性依存于分子结构的变化 ,丝胶的胶粘强度与丝胶分子 β结构比率 (%)的变化呈“S”型曲线 ,其关系式为 : y[丝胶分子 β结构比率 (%) ]=59 701 +4 0 0 2e- 0 0 0 1X[胶粘强度 (N/mm2 ) ] .“,”Based on the instrument analysis and mathematical statistics,it shows that the adhesive properties are dependent on the structural change of sericin molecules.The curve of relationship between the adhesive strength and the molecular structure of sericin is the shape of “S”.Its formula is: y[ratio of β structure(%)]=59.701+40.02e -0 001X[adhesive strength (N/mm 2)]
