The second chapter is the main part of this paper, in which the formulation of the Riemann boundary value problem of non-normal type on the real axis, the solution method of homogeneous problem, the relation between the two kinds of different derivatives and the inhomogeneous problem will be thoroughly given. In this paper, the solution and the solvability of the Riemann boundary value problem of non-normal type on the real axis will be given.

Operations are given and testified in this paper. The research methods of intrinsical linear nonholonomic dynamics are similar to those of holonomic dynamics.The rationality and equivalence of Chetaev model and Vacco model in the intrinsical linear nonholonomic system are testified from the mathematic and mechanical aspects. The essential reason is the nonlinear property of intrinsical nonlinear nonholonomic constrain that bring on Chetaev model and Vacco model inequivalent. Chetaev model is a linear approximate method in intrinsical nonlinear nonholonomic system. Vacco dynamical equations are not satisfied to the ideal constraint force conditions, but it gives a significative ponderation on the realizations of intrinsical nonlinear nonholonomic constrain.

The correct rates and the mean response latencies were subjected to ANOVA with repeated measures. Result:In both supraliminal and subliminal affective priming tasks, the mean response latencies were significantly longer for affectively incongruent trials, as compared to those for affectively congruent and control trials. The correct rates for affectively incongruent trials were the lowest.Subjects were relatively slower to respond to positive target pictures than to negative target pictures(96.9%/95.3%,97.6%/95.8%).In subliminal affective priming task, there were no differences of correct rates and latencies between alexithymics and nonalexithymics. In supraliminal priming task, the latency of alexithymics was longer than that of nonalexithymics (536.3ms/496.4ms).
