主要的表现是：第一，Reynolds stress 张量和磁扰动张量的径向分量贡献给压强，引起太阳内部流体静力学平衡方程和太阳内部热力学变量的改变，从而导致温度、密度、内能、绝热指数以及绝热温度梯度等的变化。

For the uniformly ergodic Markov processes, which is a classic framwork established by Deuschel-Stroock for studying the LDP for empirical measures, the LDP of f_n~* in the weak topology and the uniform weak*-LDP in the strong topology ||·||_1 for f_n~* are established. Furthermore, we prove that f_n~* is asymptotic optimal in the sense of Bahadur. These results are obtained for the first time in the dependent case. For this generalization from the i.i.d.

在此框架下，我们建立了f_n~*在弱拓扑下的大偏差原理以及在L~1-拓扑下对初始点一致的弱*大偏差原理，另外，我们还证明了f_n~*在Bahadur意义下是渐近最优的，这些结果在相依情形下是全新的，为了做这样本质性的推广，我们需要克服许(来源：ABC论文6d网www.abclunwen.com)多技术上的困难和应用不少特殊的工具，诸如Harnack型不等式，Cramèr型偏差不等式，一致可积算子，线性算子的扰动理论，Bishop-Phelps定理等等(它们都是首次用于处理这样的问题)。

Also, during this process, the water content in vegetation increases and keeps stable gradually, and the water environment in ecosystem will become suavely.

摘 要：本文以南亚热带常绿阔叶林为基本，同时探讨了热带南亚热带森林演替系列中8种生态系统类型的水分结构，发现植被水分结构的恢复与土壤水分结构的恢复是不同步的，50a以上没有受扰动的土壤，其土壤水分结构在时空上才趋于稳定；植被水分结构的时空稳定性基本上与生态系统的演替状况一致；为满足植被蒸腾的需要，植被中水分的月更新次数随着群落向顶极系统的演替而逐渐减少。

In the full paper which outlines our special design strategy; the two subtopics of topic 2 are the establishment of multi-models and switch conditions （subtopic 2.1） and the analysis of stability（subtopic 2.2）; in subtopic 2.2, based on the book written by Wang et al, we explain how all the controllers can have dynamic performances that are very similar in topic 3, we point out that eq.

首先建立作动器故障参数模型；然后根据故障的随机性，设计一系列并行的辨识模型，每个模型对应一种故障，同时对应于每个辨识模型建立一个控制器；最后根据飞行品质的要求，设计鲁棒跟踪控制器，由于控制器采用了积分项，可很好地抑制扰动。

Borel summation finds application in perturbation theory where physicists frequently require the sum of a series even though it is divergent.

应用 Borel 总和在，即使它是的，物理学家经常需要系列的总和。扰动理论方面发现应用。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
