Meanwhile, compared to the calcium nitrate treated for 4 h and 8 h, the discs treated for 12 h were more apparently promoted or inhibited based on above maturation and consenescence physiological parameters; however, with the prolonging of treated time to 24 h, the activities of POD, SOD and CAT dropped markedly, as well as the inhibition of synthesis of soluble protein, and the increased speed of electrical conductivity and LOX activity were reduced markedly.

Analysis of dynamical simulation data shows as follows: Wheel tread LMA is able to satisfy the requirements of the 300 km/h~350 km/h high-speed wheel-rail technology, and wheel tread XP55 is able to reach 250 km/h~300 km/h; the main issue of Wheel tread LM is that the larger equivalent conicity may cause the bigger lateral wheel-rail force, and wheel tread S1002 has the severe problem of harmful wheel-rail wear.

动态仿真数据分析表明：LMA型车轮踏面可以满足300 km/h~350 km/h高速轮轨技术要求，而XP55型踏面则可以满足250 km/h~300 km/h速度的要求；LM型踏面的主要问题是等效锥度比较大，从而造成轮轨横向力也比较大，S1002型踏面对轮轨存在比较严重的有害磨耗问题。

Their seasonal variations were related with vegetation characteristics such as leaf area index and canopy height as well as wind speed.d had a close linear relationship with h,and the variations of Z0 with h could be expressed by quadric curves.d/h and Z0/h were nearly correlated with LAI,and multiple correlation coefficient could be 0.99 and 0.78,respectively.

In addition, the changes of molecular geometry, atomic natural charge and IR spectra of the reaction system during the crucial step of O to attack H showed that the rupture of C—H bond and the formation of O—H bond were concerted stepwise. Obvious changes of atomic natural charge happened to atoms C(1), H(11), O(28), O(29) and N(27). The bond lengths and bond angles related to these atoms were also varied greatly.
