查询词典 closed system

Closed system architecture. Neither the traditional system architecture, nor the noticeable backbone architecture can supply system with enough flexibility. Also they can not create a neutral platform to integrate other systems conveniently.

系统结构方面：无论是传统的独立运作系统，目前广泛使用的套件配置模式，还是倍受注目的主干结构，都不能为系统提供一个全面开放的系统结构或完全中立的集成框架。

More attention is being focused on the deepburial closedsystem dolomitization. Some dolomitization of practical significance to the oil/gas reservoir and to the stratabounded deposits mainly occurred in closed system, which is different from the open system in the contribution to the change of reservoir space and the corresponding geochemical index.

3深埋藏条件下封闭系统的白云化作用受到关注：一些对油气储集空间和层控矿床有较大意义的白云化作用主要是在相对封闭条件下发生的，在对岩石储集空间的变化的贡献上以及在相应的地球化学指标上不同于开放条件下的白云化作用。

The hydraulic loading system is developed and used to study the frost heaving characteristics of the subgrade soils under dynamic loading in closed system and open system . On the base of these work, the conclusions are as follows:1. Because of the the fine-grained fill, the frost deformations of Beijing-Baotou railway subgrade and Baotou-Lanzhou railway subgrade are holistically irregular, and great discrepancies exist among the frost heavings of subgrade at different sections.

本文根据冻害较严重的京包铁路、包兰铁路的气候、地质条件的调查和路基冻胀变形监测，结合路基土的性质对京包铁路、包兰铁路的冻害给出了评价；为了模拟振动荷载作用下土的冻胀，研制了液压动力加载系统；在室内采用实验方法对列车动荷载作用下包兰线路基粉质土在开敞、封闭系统下的冻胀特性进行模拟。

The simulation of the vector control system for rotor flux orientation is studied in this paper. The modeling and simulation of the vector control system of speed and flux closed-loop with the torque inside loop are completed by applying electrical principles and the toolbox of Simulink and Power System in the Matlab software. The paper mainly introduces the modeling of the speed adjustment system and the setting of parameters of the controller. The obtained results of the simulation are close to actual situation, which proves the correctness of the modeling.

参照开式系统9.14。

Moreover, based on small signal analysis method, the equivalent small-signal model of the main circuit is achieved, and the system transfer function is established by predigesting the double control loop to a single one. On the basis of transfer function, the frequency characteristic of the system is analyzed and the compensator is designed. Emulation results show a good dynamic characteristic of the closed system.

同时，采用小信号分析的方法，建立了开关电源主电路的等效小信号模型，并通过将电流电压双环控制系统转化为单环控制系统获得了开关电源系统的传递函数，在分析系统频率特性的基础上设计了系统的补偿器，仿真结果表明，补偿后的系统具有良好的动态特性。
