存在状态

• By means of linear matrix inequalities , a sufficient condition is given such that a prescribed discrete singular system is admissible and strictly passive . moreover , under certain conditions , a static state feedback control law is designed such that the resulting closed - loop system is both admissible and strictly passive
  利用线性矩阵不等式，给出离散广义系统容许且严格无源的充分条件，并且基于此条件在一定假设下给出存在状态反馈控制器，使得闭环系统容许且严格无源的充分条件。
• The robust h control problems of nonlinear systems with state perturbations are studied . the corresponding sufficient conditions for the solvability of h control problems via the state feedback control , the output control and the output control based on observers are put forward , while the design methods of these kind controller are proposed . then the performance criteria design is discussed for a class of nonlinear uncertain systems with state perturbations and state ' s derivative perturbations as well
  探讨了仅存在状态摄动的不确定非线性系统的鲁棒h _控制问题，给出了此类系统的状态反馈、输出反馈以及基于观测器的输出反馈的h _控制问题有解的充分条件和控制器的设计方法；在此基础上，进一步探讨了同时含有状态摄动和状态导数摄动的不确定非线性系统的鲁棒性能准则设计问题。
• People ' s attitudes to the hardcore of higher education have changed . they no longer regard it as " self service " and " special talent - service justness " . as a matter of fact , it forces higher education to change its model of elitism , to accept the lanitation of the old model of the tvay and methods of higher education
  同时，人们对高等教育的核心? ?知识原有的“自为”存在状态和“才本位公正”的获取状态的看法出现了不同认识，由此它要求改变高等教育的精英培养模式并打破接受高等教育在途径和方法等许多方面的旧有限制，这又导致高等教育体制在内生环境的催动下“不能不”变革。
• The author finds that the consumption phenomena is a sort of communication phenomena which has a widen connotation and a macroscopic field of vision . the innovation of this thesis is that it compounds the communication theories with the consumption theories , in order to analyze each essential factor through consumption communication courses . it succeeds in achieving the cognizance of existence state and existence form of message , and drawing the outline of consumption communication zoology
  本文的创新之处在于,将传统的传播学理论和消费社会的相关理论合理的运用到阐释和剖析消费传播的全过程,并逐一地对整个消费传播各个要素环节及其相关关系进行分析,在对消费传播细致考察的过程中,成功的完成了对于信息存在状态、存在方式和流通过程的考察和认定,具体分析了消费传播的状态特征,简要地勾勒出整个消费传播生态谱系的框架和特征,基本使消费传播学体系的构架拥有了较为系统的展现。
• Low temperature plasma can create kinds of active particles ( some carry electric charge , some not ) , some activities that are difficult or not able to carry out below normal condition will be very easy to deal with , it is a kind of low temperature with high energy dry technique
  等离子体有着诸多特殊的性质，是物质的一种存在状态。低温等离子体能高效产生各种活性粒子（中性的或带电的） ，常规条件下不能或不易发生的反应，在等离子体的环境中较容易发生，是一种低温高能的干式工艺。
• In this book , liu xin has not only successfully summarized the existence of the chinese in the transitional period as " the otherness of self " but also brought up some enlightening views on the development of ethnographical methods in the new period as follows : the analysis of the characters should develop into a special method in anthropology for understanding a given society or history ; there should be a re - xamination of the concept of " truthfulness " in the classical ethnographies ; a historical standpoint should be adopted to avoid taking subjectivity as a kind of entity or nature in ethnographies
  其不仅成功地将转型时期中国人的存在状态概括为“自我的他性” ，而且对人类学民族志方法在新时期的发展提出了极具启发性的见解：对人物的分析应当发展成为人类学理解社会和历史的特殊方式；经典民族志所呈现的“真实”的概念需要重新加以审视；反对在民族志中将主体性当作一种类似实体或本质的东西，而应采取历史主义的立场。
• After identifying the parameters , because of the multiplication terms of state variables , the induction motor model is still the non - linear state equations . to estimate the state variables of motor model and gain the rotor flux and velocity signals , the paper proposes a method to estimate them using extended kalman filter
  在电机参数进行辨识以后，电机状态方程由于存在状态变量的乘积项，仍然是非线性方程，为了对电机状态方程进行状态估计，得到电机的转子磁链和转速信号，本文采用扩展卡尔曼滤波进行状态估计。
• This thesis , from the point view of the theory of communication and feminism , taking the mass media ' s analysis of the female as an object of study , tries to analyze how today ' s mass media present the female image , and the current condition and the speech dilemma of the women in mass media ; it also from the angle of news communication and feminism makes some discussion and meditation about the communicator ' s psychological and cultural sediment , the improvement of feminine consciousness , and other levels like these . all of which is trying to adds a new module for the study of today ' s feminism
  本文以当代大众传媒对女性的解读为考察对象，试图从传播理论和女性主义角度出发，对当代大众传媒在表现女性形象、女性在大众传媒传播中的存在状态及话语困境进行分析，通过对媒体有关女性诸多表征的解读，从新闻传播视角和女性主义视角，在传播者心理文化沉淀、女性意识发展等层面进行一些探讨和思考，为当代女性主义研究增添一个新的模块。
• Pure materials exert a grip on the subconscious as they exist between consciousness and the absence of . through the artists conception , colour and texture of light and the characteristics of photography , these materials adopt a unique existence and state , representing the inner mind of the artist
  纯粹的物料在意识和无意识之间，并发出一种潜意识的执著：物料通过作者的内在思维，利用光线的颜色和质感，通过摄影的特性，形成一种独特的存在状态，象徵著作者的内在思维。
