Donghua steel continuous casting-rolling(DSCCR)production line is an endless rolling production line independently integrated and developed by a Chinese *** solve the problem of out-of-control shape caused by insufficient adjustment ability of work roll bending force of DSCCR finishing mills,the backup roll contours of the finishing mill were optimized considering multi-objectives,and varying contact length backup roll(VCR)contours matching the concave work rolls were designed based on the rapid rolls-strip deformation calculation model,which integrated the elastic deformation of the rolls and the fast plastic deformation of the rolled *** simulation results showed that VCR configuration can significantly enhance the control efficiency of the work roll bending force and increase the transverse stiffness of rolling mill compared with the conventional roll *** addition,VCR backup roll can improve the contact state between backup roll and work *** industrial production showed that the bending force setup value was more reasonable and the strip crown control accuracy was improved.

Objective: To evaluate the value of identifying and diagnosing mammary carcinoma and non-lactation mastitis lump (NLM) by multicolor Doppler ultrasonography. Methods: We compared and analyzed the examination results of 69 cases of mammary carcinoma proved by surgical pathology and 22 cases of NLM before surgery by multicolor Doppler ultra-sonography. Results: The detection rates of mammary carcinoma and NLM focus by ultrasonic examining were 100%. The shape, envelope, foul line, blood stream between sound and image of two diseases were similar. Of the two diseases, the representation with slight calcification in lump, lower echo in low echo, bloodstream distribution and resistance were different. Conclusion: By analyzing the sound and image representation of mammary lump, we find color Doppler ultrasonography has significant value in identifying and diagnosing mammary carcinoma and non-lactation mastitis lump.

关键词： mammary carcinoma non-lactation mastitis lump (NLM) color Doppler ultrasonography
