This study aims to reduce the work-affected layer of the machined surface by carrying out the grinding at the speed over static pr o pagation speed of plastic wave of ductile materials and also aims to clarify suc h super high-speed machining mechanism.This paper reports on the result obtain ed through the molecular dynamics simulations and experiments on the super-spee d grinding below and beyond static propagation speed of aluminum.From the simul ation results,it is verified that the plastic deformation is reduced when the m a chining speed exceeds the material static propagation speed of plastic wave and its mechanism is completely different from that of the ordinary grinding process .Experimental results also show the improvement of the surface integrity when t he machining speed exceeds the material static propagation speed of plastic wave . 展开更多

Objective:To explore the clinical efficacy of plastic surgery of asymmetric double eyelid.Methods:The clinical data of 70 patients with asymmetrical double eyelid who underwent plastic surgery in our hospital from April 2018 to December 2019 were retrospectively analyzed.The patients were divided into different groups based on different plastic surgery procedures.The control group(n=35 cases)were the patients who underwent double eyelid incision method,and the patients who used embedding double eyelid method were included in the observation group(n=35 cases).The operation time,intraoperative blood loss,incision size,healing time of incision,satisfaction of p1astic surgery and occurrence of complications were compared between the two groups.Results:The operation time and incision healing time of the observation group were shorter than those of the control group.The intraoperative blood 1oss and incision were less than those of the control group,and the satisfaction was higher than that of the control group.The difference was statistically significant(P<0.05).The incidence of complications in the observation group was slightly lower than the control group,but the difference was not statistically significant(P>0.05).Conclusion:For asymmetric double eyelid,it should undergo embedding double eyelid plastic surgery,because the operation time and incision healing time are shorter.And intraoperative blood 1oss and incision size are smal1er,which can improve patient satisfaction and reduce the incidence of complications. 展开更多
