The adaptor is a must for numerous computer peripherals. As an important computer exporter worldwide, the dc power supply industry is bloomy in Taiwan. In today's dc power supply market, the switch power supply has replaced the linear adaptor as main stream in the industry globally for its compact size. However, SPS has a serious problem of high frequency electromagnetic interference and causes harmonic feedback for the AC power source compared with linear adaptor. The energy consumption is also worse for SPS than linear adaptor.

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.

Linear CO desorbs earlier and quicker than twin and bridged CO with the progressive heating from 25 to 300°C at 0.1MPa, and the three types of adsorption disappear at 265℃.At 205℃ the adsorption amount of linear CO and bridged CO increases with the pressure from 0.1 to 3.0MPa, but the adsorption amount of bridged CO is more than that of linear CO. At 0.1MPa and 25℃, CO2can decompose into CO and then CO adsorbs quickly, namely, CO2→CO+O, but the wave numbers of the adsorptive CO from decomposed CO2 are different from the pure CO, which demonstrates the effect of on CO adsorption. With the pressure of CO2 from 0.1 to 3.0MPa at 25℃, the total adsorption amount increases and the band at 2052cm^(-1) shifts towards higher frequency.
