电解 0.1 mol/L CuSO4 溶液 阴极反应（-）：Cu2+ + 2e ＝ Cu 阳极反应（+）：2H2O ＝ O2  + 4H+ +4e 电池反应：2Cu2+ + 2H2O = 2Cu + O2 + 4H+

Stationary Stochastic Process e A stochastic process is stationary if for every collection of time indices 11 e Thus, stationarity implies that the x,'s are dentically distributed and that the nature of any correlation between adjacent terms is

We will now approach the function A(a) from an entirely different point of view, i.e.,we will interpret the S-fabric in terms of strain1. (1.) We assume that the initial fabric is defined by a random orientation of surface, i.e.,that the ODF of the surface is uniform;
