摄动参数 meaning in English
perturbation parameter
Examples
- In this chapter , the stability judgements are proposed for the sps in four conditions respectively . they can offer the upper bound of the dead - time and the perturbed parameter . an application example shows that the judgements are easy to use
本章通过对一类奇异摄动时滞不确定系统的研究，给出了该类系统在四种情况下出现参数范数有界摄动时保证系统稳定的时滞t和奇异摄动参数。 - Its biquadratic finite element approximation is considered and under the appropriately graded meshes , quasi - optimal order error estimates in the - weighted h ^ 1 - norm , up to a logarithmic factor in the singular perturbation parameter , are proved
然后，考虑此方程在分层网格剖分上的双二次有限元逼近，在-加权h ^ 1 -模意义下得到了至多相差一个关于摄动参数对数因子的拟最优阶收敛的误差估计。 - However , it is difficult to choose proper perturbation parameter in the process of applying this method . even in present day , there have not a dependable norm to confirm certain parameter and researcher often search it through engineering experience
但选择摄动参数却是正则摄动法求解过程中的一个比较困难的问题，现在对于这一问题仍然没有一个一般的原则，而主要是利用经验对该问题进行处理。 - In the last , the problem of the perturbation of fuzzy reasoning is discussed in detail , and the maximum perturbation parameters for various methods of fuzzy reasoning is estimated according to the choice of conjunctive operator and implication operator
根据椎理规则中合取算子与蕴涵算子的不同选取方式，对各种模糊推理方法的最大摄动参数进行了评估，为实际应用中选择恰当的模糊推理方法提供了一个准则 - By this method of analysis , researcher can get all of elastic characters without choosing proper perturbation parameter to create perturbation solution . since this method of analysis reduce the experience factors in the process of analysis , the results of it can be more reasonable
采用该方法求解板以及壳体的大挠度问题，研究者无须具体选择摄动解的摄动参数就能够得出问题的全部弹性特征，减少了在摄动过程中的先验因素，使得求解结果更趋于合理。
