To put the icing on the cake , say this vendor starts to charge someone perhaps the merchant and , indirectly , the consumer every time its servers are used for authentication by this client 窃贼使用小薄片或其它类似工具来开锁，或者打碎窗户，或者可能用枪劫持并偷车，或者等待机会看哪辆车没锁或处于不安全状态。
The decoupling control system designed on this theory is not robust . 3 . the decoupling control theory based on eigenstructure assignment is studied , also includes two cases : full state feedback and output feedback 3 、进行了线性定常系统基于特征结构配置的解耦控制研究，分别考虑了全状态反馈和输出反馈两种情况。
A team of researchers has identified a new genetic mutation responsible for osteogenesis imperfecta ( oi ) , a condition that makes bones much more likely to break , according to a study published today in the journal cell 今天的细胞学杂志说：一个研究团队鉴定出导致成骨不全( oi )的一种新的基因突变，而成骨不全状态可导致骨骼更易折断。
Based on cause analysis of numerous accidents , it is seen that accidents are caused just by the unsafe behavior of the people and the unsafe state of the thing , and the unsafe state of the thing is caused exactly by human factors 分析众多事故的原因，无外乎是由人的不安全行为和物的不安全状态造成的，而物的不安全状态归根到底也是人的因素造成的。
The auxiliary modulating signals of the current controller at the rectifier and the extinction angle controller at the inverter , and the reference voltage of exciter are chosen to be control variables . then the all - state feedback linear optimal controller is designed 以直流系统整流侧电流控制器的辅助调节信号、逆变侧关断角控制器的辅助调节信号以及励磁系统参考电压作为控制变量,设计了系统的全状态反馈线性最优控制器。
Construction safety management and construction the safe technique is two basic factors to realizes safety produce target manage . although the safe technique of the continuous changes and improvements can dissolve the safe hidden trouble of the equipments tool gets the blemish with the environmental insecurity in homework appearance , but the safe machine tool in innate character design principle is then further to guarantee homework the employee ' s life safety 施工安全管理与施工安全技术是实现安全生产目标管理的两个基本因素。虽然日新月异的安全技术可以消除设备工具的隐患缺陷和作业环境的不安全状态，而本质安全的机具设计理念则更进一步保障作业员工的生命安全。
In this paper , the present research and development of the engine vibration control is summarized . in theory , this paper analyzes energy distribution of the engine vibration and discusses the active global - state - feedback control system and the partial - state - feedback control system , and presents the method in selecting the partial feedback states . at the same time , associated with one category of engine , it builds the mathematical model of the engine active control system , provides the lq optimal control strategy and makes a simulation analysis 本文总结了发动机振动控制的研究和发展现状，从理论上，分析了发动机振动的能量分布情况，阐述了发动机的全状态反馈施控系统和部分状态施控反馈系统，并提出了部分施控的状态选取方法，同时结合某具体型号的发动机，建立了发动机的振动主动控制模型，采用以二次型性能指标的最优控制律，进行了整机振动主动控制模拟分析。
It says deficiencies of management system , including ( but not limited ) company management system for safe operations and maritime safety administration system , is the root cause of accident causation . it causes crew " s quality deficiencies , unfitness of cargo , and dangerous navigation circumstances , which further more cause unsafe behavior of crew members , unsafe condition of ship and cargo onboard , and / or high risks of circumstances , that lead to undesired event ( s ) . those may or may not result in initial loss , depending on circumstances 该理论认为，包括航运公司船舶管理体系和海事机构监督管理体系缺陷在内的管理缺陷是水上交通事故发生的根本原因，它产生船员的素质缺陷、船舶不适航和货物不适运、以及航行环境的不良，进而造成船员的不安全行为、船舶、货物的不安全状态和或不安全的航行环境，因此造成事故的发生，产生初始损失，如由于应急措施不当，则导致最终损失。
From the view of safety system engineering , unsafe human behavior and unsafe state of object in road traffic system could be eliminated by formulating scientific and rational urban road traffic safety management plan , perfecting urban traffic accident emergency rescue system , reinforcing traffic participants ' safety awareness and comprehensively coordinating the relationship among roads , traffic flaw and road administrators 从安全系统工程的角度，提出通过制定科学合理的城市道路交通安全管理规划和建立健全城市交通事故紧急救援系统、加强交通参与者的交通安全意识、综合协调道路交通流管理者之间的关系，以消除道路交通系统中人的不安全行为和物的不安全状态。
Firstly , based on backstepping and the supervisory control strategy , a robust adaptive fuzzy controller is designed for a class of nonlinear systems . the first type fuzzy logic system is used to approximate the unknown part of the process . the adaptive compensation term of the optimal approximation error is adopted 本文首先针对一类不确定非线性系统，基于backstepping方法，利用监督控制，引入最优逼近误差的自适应补偿项，并利用型模糊逻辑系统逼近系统的未知部分，提出了一种鲁棒自适应模糊控制器设计方案，运用李亚普诺夫第二方法，先证明了闭环模糊控制系统全状态有界，再证明了跟踪误差收敛到零。
