查询词典 number system

In the non dimensioned time domain,the generalized quadratic performance criterion of error state transits into the optimal problem of structural parameters,thus gets an optimal parameter system—optimal damping control system with big margin for stability,little number for oscillation,small overshoot,and small setting time.

In view of the system complexity, it is difficult for a number of previous methods to consider the embedded cap effects on the dynamic pile-soil interaction system. As a result, the dynamic impedance of a pile group with embedded cap was rarely reported.

由于系统的复杂性，以往桩-土动力相互作用研究的很多方法难以考虑承台的埋置作用，因此有关埋置承台群桩动力特性的研究报道很少。

The quorum cluster including only three quorums is a small quorum system; every two quorum clusters intersected only one quorum. Circle quorum system used self-adaptive fault-tolerant protocol, which decided to use voting protocol or mutual exclusion protocol based on the failure probability and number of points of one quorum.

Circle Quorum系统采用了自适应容错协议，根据quorum内部节点的非等失效概率和失效个数决定采用选举协议还是互斥协议。quorum中所有节点组成选举quorum，其中，具有高可靠性的若干节点组成高性能响应子quorum。

Based on the given probability distribution of a system mode, the F-discrepancy or quasi F-discrepancy representative points and the mean square error representative points representing the probability distribution of system mode are selected by means of number-theoretic method. The model-set used in a multiple-model approach is then constructed.

在已知系统模式的概率分布条件下，由数论方法获得代表其概率分布的F-偏差或伪F-偏差代表点和均方差代表点，利用这些代表点构成覆盖系统模式空间的模型集合。

If it be shown in a reasonable number of well-authenticated cases that these conditions — exogamy as tribal law, and hostility as the prevailing relation of separate tribes towards each other — exist or have existed, accompanied, as might have been expected, by a system of capturing wives, we shall be justified in concluding — failing the appearance of any phenomena inconsistent with such an explanation — that the same conditions have existed in every case where the system of capture prevailed, or where the form of capture has been observed as a ceremony of marriage. Nothing more than this is necessary to satisfy the conditions of a sound hypothesis.We are in a position to do this and more.

并且如果它被证明在一个合理数目的被充分鉴别的案例中这些条件（异族结婚为部落法律，以及对抗是分离的部落相互对待的主要关系）存在或曾经存在，伴随着似可预期的一种猎妻制度，我们将被证明在做出结论时是正确的（舍弃与这样一种假设不协调的现象的出现）这些相同条件存在于流行劫掠制度、或者劫掠形式在婚礼中被观察到的地方的每一个案例。

对系统实现所涉及的技术做了研究，包括网络数据库的体系结构及实现技术，CAD图形的处理方法。

In this thesis, we contrast and study a number of new driving-principles and driving-modes of robot, then propose a new working principle and electromagnetic driving-system of the new wall-climbing micro-robot, and analyzed the power of the robot's driving-system.

论文首先对现有机器人的各种新型驱动原理及驱动方式进行了大量的分析对比研究，提出了一种适用于微小步行爬壁机器人的新颖工作原理和电磁直接驱动方式。

A conventional two-circle diffraction system is set up. The work includes the design of light route, the establishment of control system for step motor and data collection, and the adjustment of the facility. A number of multilayers are measured using the diffractometer and a lot of useful experimental data are obtained.

作者在一台12KW转靶X光机的基础上，从光路设计到步进马达、数据采集等一套控制系统的建立，搭置了一台二圆衍射系统，并利用它做了大量的多层膜样品测量工作，并取得了一批有用的实验数据。

The system is based on geographic information, ecology and tobacco leaf quality, flue-cured tobacco production and infrastructure management, three-dimensional visualization, WEB information composed of 5 sub-systems, with the objective of tobacco-growing areas of Qujing weather, soil, geomorphological features, tobacco production, infrastructure and basic tobacco-related information management, query and spatial statistics to show the application of tobacco-depth analysis of the topic, the establishment of expert decision support system,"the number of tobacco."

该系统由基础地理信息、植烟生态及烟叶品质、烤烟生产与基础设施管理、三维可视化、WEB信息查询5个子系统组成，目标是实现对曲靖烟区气象、土壤、地物地貌、烟叶生产、基础设施及基本烟田管理等相关信息的查询统计和空间展现，并对烟草专题应用进行深入分析，建立专家辅助决策系统，实现&数字烟草&。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
