查询词典 plant factor

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 order to improve the reliability of the nuclear Generating Sets and the stabilization of the power system, prevent the long time low frequency oscillation caused by the disturbed of the outside electrical net, assured improving the stabilization margin of the nuclear generating sets in the precondition of enough transient stability, validate the sensitivity of the parameter to the damping of Generating Sets of the MEC5220 digital excitation adjustor produce in Japan that used in the Second Project of Qinshan Nuclear Power Plant, confirm the parameter rationality of the digital excitation adjustor, optimize the parameter of PSS, in this paper, we put up a in-depth study to the principle of MEC5220 digital adjustor produce in Japan by the PSS/E software that develop by the PTI Company in the USA, completed the modeling of the excitation adjustor, PSS, generator, excitor, described the performance of this excitation adjustor, analyzed the essential reason that caused the low frequency oscillation, illuminated the factor that influence the damping characteristic of the MEC5220 digital excitation adjustor. Based on model and emulate, this paper optimized the primary parameter of the excitation adjustor, make a reasonable regulation to the PSS parameter.

为提高核电机组的运行可靠性和接入系统的安全稳定性，防止在外电网的干扰下核电机组发生长时间的低频振荡，保证机组在暂态稳定的前提下提高其稳定裕度，验证秦山核电二期核电机组所配日产MEC5220型数字式励磁调节器参数对机组阻尼的灵敏性，确定数字式励磁调节器的参数的合理性，优化PSS整定参数，本文利用美国PTI公司研发的PSS／E软件对日产MEC5220型数字调节器的原理进行进行了深入细化的研究，完成了励磁调节器、PSS、发电机、励磁机的建模，描述了该型励磁调节器的性能，分析了产生低频振荡的根本原因，阐明了影响阻尼特性的因素。
