It is the key factor regulating programmed cell death in pathogen,evocator and hormone responses.H_2O_2 has also been proved to play the signal role in defensive response to environmental stresses.H_2O_2 is known of directly regulating the expressions of numerous genes and some of these genes relate to plant defense and hypersensitive response.H_2O_2 also interacts with other signal systems,especially hormone signal system,and forms upstream or downstream components of hormone-mediated signal-transmitting passageways;more importantly,H_2O_2 also work to exert influence on or modify other secondary signals such as calcium signal between which and H_2O_2 many interactions take place;and both of these two signals regulate interactive tolerances of plants.
已知H2O2直接调节无数基因的表达,其中有些基因与植物防御和超敏反应有关。H2O2还与其它信号系统特别是激素信号相互作用,是激素介导的信号传导通路上的上游或下游组分;更重要的是H2O2还影响和修饰其它第二信使如钙信号的作用,在H2O2信号和钙信号之间发生众多的交互作用且这两种信号分子都调节植物对多种胁迫的交互耐性。

In the analysis, firstly, the flux boundary condition is used to simulate the frictional heat resource between wheel and rail. The non-steady heat transfer between the contacting surfaces of the wheel/rail, heat-convection and radiation between the wheel/rail and the ambient were all taken into consideration. Therefore, a heat coupling model of the wheel/rail in rolling/sliding is put forward to calculate the frictional temperature rise in the wheel and rail. Secondly, after the temperature distribution of wheel/rail, due to friction, is calculated, substitute the thermal load with equivalent fictitious body force and boundary distributed force loaded on the nodes of the corresponding elements. The wheel-load is applied to the center of the wheel.
