在传统煮茧工艺的调整段和保护段之间增加超声波处理工序,通过模糊正交法及夹角余弦赋权法,得出解舒率、光折和千米茧丝的疵点数等主要评价指标的权重向量,依据正交实验的模糊运算法则,用模糊综合评判模型得出微波煮茧的最优工艺:超声波功率75 W,超声时间90 s,超声温度60℃,超声浴比1∶27。试缫结果表明,超声波辅助煮茧优于直接煮茧工艺,在最优的超声波辅助煮茧工艺下的光折为262.75 kg、解舒率为64.41%、千米疵点数为0.355 6个。采用超声波辅助煮茧工艺操作简单、煮茧效率高、耗能小、清洁性好,研究可为超声波辅助煮茧技术的进一步研究和应用提供依据。

The temperature effects on the evolution and self-deflection of bright spatial optical solitons in photo-voltaic photorefractive media were investigated by taking into account diffusion effects. The numerical results show that the evolution of the bright solitary beam depends strongly on the crystal temperature. It is also found that the bending distance of the bright solitary beam centre increases and reaches its maximum value at a characteristic temperature, and then decreases as temperature rises and ap-proaches zero at low and high temperatures. Both the maximum value and characteristic temperature increase with the input power density. The self-deflection of bright solitary beam is further studied by a perturbation technique, and the results are found to be in good agreement with that obtained by the numerical method. The diffusion process and the dark irradiance dominate the temperature depend-ence of bending distance in most values of temperature besides at the characteristic temperature and in the higher temperature regime. The diffusion process will mainly dominate the temperature dependence at the characteristic temperature and the dark irradiance will dominate in the higher tem-perature range.

系统地研究微波煮茧工艺,并首次通过模糊正交法及夹角余弦赋权法,得出主要评价指标解舒率、光折及千米茧丝的疵点数的权重向量,依据正交实验的模糊运算法则用模糊综合评判模型得出微波煮茧的最优工艺为:微波煮茧水初始温度80℃,3min,微波火力为中火,浴比为1:40。通过试缫可知,利用微波进行煮茧可以显著的提高缫丝的解舒率,降低光折和千米米茧丝的疵点个数。
