The Barzilai and Borwein (BB) gradient method has achieved a lot of at-tentions since it performs much more better than the classical steepest descent method.In this work,we analyze a positive BB-like gradient stepsize and discuss its possible uses.Specifically,we present an analysis of the positive stepsize for two-dimensional strictly convex quadratic functions and prove the R-superlinear convergence under some assumption.

双电层电容器(EDLC)的原理1.依靠电极与电解析质界面上形成的双电层来储存电荷,一个双电层电容器可以看作由两个界面双电层电容串联二成.2.由于界面双电层的正负电荷之间距离很小,且界面的面积可以做的很大,因此双电层电容器具有非常高的容量.
