查询词典 angle iron

Then, aerodynamic parameters in different flight conditions are used to imitate the uncertainty of the system, and the digital simulation of closed-loop system designed is performed. The results show that the system can accomplish asymptotic decoupling of roll angle, sideslip angle and head-on angle for aircraft, and the system is provided with the function for restraining uncertainty in the system. This illustrates that the flight control system designed has not only good decoupling characteristic, but also better robustness.

然后用不同飞行条件下的空气动力参数变化来模拟系统的不确定性，并进行闭环系统数字仿真，结果表明，所设计的控制律不仅可实现对飞机滚转角、侧滑角、迎角等的渐近解耦控制，而且对系统不确定性具有较强的抑制作用，说明系统具有较好的解耦性和较强的鲁棒性。

The system can automatically seek north when the vehicle is immobile. And the time consumption is no more than 5.5 min. Besides, the system can keep azimuth angle and provide tilt angle and pitch angle of the vehicle.

Firstly, the control of reentry phase and the model of RCS jets are presented. Then the flight control system is divided into two subsystems based on the time-scale separation principle. The fast states subsystem corresponds to the three body-axis angular rates, the slow states subsystem controls the angle-of-attack, sideslip angle and the rate of the bank angle about the velocity vector. Lastly, the proportional-plus-integral feedback is designed to increase the system robustness.

首先，分析了SRLV再入段的数学模型，并给出了反作用推力控制系统的控制模型；其次，将非线性动态逆方法与时标分离原则相结合，考虑飞行器姿态控制系统的外环角回路的慢变特性和内环角速度回路的快变特性，独立设计了两个回路的控制律；最后，为了增强系统的鲁棒性，分别在两个回路中引入了比例－积分反馈，有效地抑制了干扰力、力矩和非线性对消带来的逆误差。

内容摘要在冶金工业生产中经常见到轧钢过程中的跑钢现象造成人体的贯通性烧伤，因为烧伤损伤深而创口小，即为临床治疗带来了极大的困难。

The biomass of iron bacteria in the BAC filter column was abundant, the number in the top was 7.60×10~3cfu/g. A pure bacterium was obtained through three times separation and purification, and bacterium maybe was Gallionella ferruginea, which was the high efficiency bacterium of removal iron.

宝钢现场的BAC成熟滤柱内铁氧化细菌量丰富，滤柱上部的数目为7.60×10~3cfu/g干炭，分离纯化三次后可得到一株纯菌，该菌可能为嘉氏铁柄杆菌，为除铁的高效菌。

It is reported that domestic steel mills have agreed with Rio Tinto chief in accordance with the Association last year, 6.7 fold in advance the price of iron ore price, as Nippon Steel and Rio Tinto iron ore reached a comprehensive long-HS price drop about 33%, the fluid control experts believe that a senior, this means that Rio Tinto approved in disguise starting price, but the China Steel Association has always stressed that China will not follow the initial price of Rio Tinto.

据悉，国内已有钢厂同意力拓按照去年长协价格6.7折预付铁矿石货款，由于新日铁与力拓达成的铁矿石长协价格综合降幅约33％，因此资深流体管专家认为这等于变相认可力拓的首发价，但中钢协一直强调，中方不会跟随力拓的首发价格。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
