The heat-treatment characteristics,mechanical properties,and wear behavior of four cold-forged-roll steels were studied and their microstructural characteristic
With reference to the testing standard ASTM D1894,the sliding-friction coefficient of the aluminumzinc-plated post-treatment plate was measured.To reduce the de
In this article,we introduce a notion of nonuniform wavelet frames on local fields of positive characteristic.Furthermore,we gave a complete characterization of
To fulfill the high-quality surface requirements of the Fe-36% Ni cold-rolled strip used in liquid natural gas carriers,corrosion tests were conducted on alloy
Using the method of construction,with the help of inequalities,we research the Muntz rational approximation of two kinds of special function classes,and give th
