In addition,the experimentalresults of the order parameter,correlation length,magnetic susceptibility[34] andthermal expansion given[36] show that the critical behavior in the Peierls transitioncan be described by three dimensional XY model.However,whether the specificheat behavior belongs to the universal class or not is not clear.

It shows that the critical exponents of conductivity, u, are in good agreement with the mean-field percolation value and in clear disagreement with the universal value in three dimension. This nonuniversal behavior can be interpreted as a result of the interaction between CB and polymer. The influences of the property and volume fraction of CB and radiation crosslinking on conductivity and critical exponent were also studied.

在表征表面超疏水性时，除常用的θ、α外，接触角滞后Δθ、斜面上液滴滞留在材料表面上的最大半径Rc、两种状态转化时的临界压力Δp以及液滴落下后能反弹的临界撞击速度Vc也是非常重要的参数。

Distinguishing from the former researches about CR service communication interruption, only spectrum handoff times exceed a certain number, communication interruption will occur. This strategy can reduce the COP of CR services.(3) Some coexistence issues between WRAN and DTV system are studiedFirstly, the network architecture, system parameters, and self-coexistence of Wireless Regional Area Network are investigated, and convergent performances among overlapping Base Station are simulated and validated. Then, a simple coexistent scenario between WRAN and Digital TV is designed to analyze the interference from WRAN BS to DTV receiver.

As the plastic region expansion on circle plate under extemal pressure is smaller than that under equal internal pressure, it can be qualitatively reckoned that the critical pressure of in-plane instability under external pressure is higher than that under internal pressure with the same axial displacement load.

由于外压增量导致环板内塑性区域扩展的范围小于等值内压的影响，因此可以定性的认为，在同样的轴向压缩量下，波纹管的平面失稳外压临界压力大于内压临界压力。
