These methods can make use of redundant switching status in order to make capacitors of different cells connect in parallel and to make energy transfer between adjacent cells in different switching status. Carrier phase-shifted PWM methods are further studied.

最后，本章提出了载波移相PWM方法对于新型拓扑的特殊意义，即采用移相控制，充分利用新型拓扑的各种开关冗余状态，通过变流器各级单元电容之间的并联状态补充能量，可以有效改善基波周期内各级单元的电容电压平衡问题。

In this dissertation, we develop the research work of the following three aspects based on existed work.First, using the scale-invariant property of multiscale model, i.e. Markovian among scales, a method of qth-order tree-based for multiscale representation of a class of 1-D stochastic process is presented. The multiscale stochastic model is established. The representation forms of parameter matrices, such as, the state transition matrix, the disturbance matrix, the initial state and the corresponding covariance matrix are deduced in detail. The multiscale sample paths based on distinctive order tree are presented by computer simulation.

本文在已有工作的基础上，开展了以下几个方面的研究工作： 1、根据多尺度模型尺度不变性，即利用尺度间的Markov性，给出了一类1-D随机过程基于一般q阶树的多尺度表示方法，建立了相应的多尺度动态模型，详细推导了多尺度模型中的状态转移阵、扰动阵、初始状态和相应的协方差阵，并通过计算机仿真给出了不同阶树的多尺度采样路径。

Based on a general parametric eigenstructure assignment result proposed for descriptor linear systems via proportional plus partial derivative state feedback and a result for generalized eigenvalue sensitivity problem of matrix pairs, parametric representation of the closed-loop eigenvalue sensitivities to the perturbed elements in the open-loop system matrices is obtained. An effective algorithm for eigenvalue assignment with minimum sensitivity in descriptor linear systems via proportional plus partial derivative state feedback is then proposed.

摘要基于广义线性系统比例与部分状态导数反馈参数化特征结构配置结果和矩阵对广义特征值灵敏度结果，得到了关于开环系统矩阵中摄动元素的闭环特征值灵敏度的参数表达式，并在此基础上提出了广义线性系统比例与部分状态导数反馈最小灵敏度特征值配置的有效算法。

Borkovec and Hu (1990) examined the inhibition of heart rate variability by worry, and argued that this inhibitory effect reflected the suppression of the parasympathetic nervous system.

实徵研究发现，个体在忧虑状态下相对於非忧虑状态，其心跳变异(heart rate variability；HRV)明显受抑制，从而支持此一负增强假设，并推论此一现象是来自副交感神经受到抑制。

The Parol basis is : with the development of 90's ermcononiy and the culture transmission, literature has changed a lot and given us a new appearance, which is different from the 80's developing tendency, viewing various parts of literature as a whole.

这个命名所依据的话语言说基础是：文学出现了新状态，指伴随着九十年代社会经济——文化转型而发生的广泛而多样的"新状态"，一个不同于八十年代文学景观的、新的整体性的文学发展趋势。

The article intends to start from the new crisis of description caused by the social change, the breakdown between authority and knowledge Parol, to analyse the background of the new state literatural birth, the posvibility of the new Paroll resultant, and through the analysis of the texts, to induce the features of appreation, Value and insufficiency of New Dynamic literature.

本文拟从九十年代社会转型，权力——知识话语断裂，造成新的表征危机入手，分析新状态文学诞生的背景，新的话语生成的可能，通过对本文的解析总结新状态文学的美学特征、价值和不足。

Firstly,different control strategies for sensor management are modeled by the real language measure. The legal behavior of control strategy modeled by FSA can generate a partially ordered set of controlled languages. Then an identification method of the language measure parameters based on an FSA model is proposed. The language measure creates a total ordering on the performance of the controlled languages.

首先，建立传感器管理控制策略的有限状态自动机模型，通过对可控制事件的非使能设定，描述不同控制策略；提出语言测度参数的递归估计方法与停止规则，并根据有限状态自动机模型产生语言的测度获得各种传感器控制策略的性能指标。

It is the repose of the soul, a passionless condition of body and spirit, and absolute rest obtained by the absorption of the soul into itself.

这是灵魂的安静，身体和精神的宁静状态，将灵魂融入它自身的绝对的宁静状态。

IGF2, which encodes a protein functioning as a fetal growth factor and a cell mitogen, is expressed only from paternally allele in most tissues but from both alleles in adult liver. H1 9, which acts as an RNA, is a gene of unknown function and expressed only from maternally allele.

IGF2编码的胰岛素样生长因子-2是一种胚胎生长因子及细胞有丝分裂原，在人体内大多数组织中特异地表达父系来源的等位基因，而母源等位基因处于印记状态。H19表达一种功能尚不清楚的RNA，其印记状态与IGF2相反，目前发现H19在正常组织内均为母源等位基因表达，父源等位基因印记。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
