查询词典 zero line

The criterion is formed and the fault line is detected according to the analysis of correlation degree of measured waveform and simulated waveform of each feeder line's zero sequence current.

对各馈线零序电流的实测波形和由测后模拟法所求解的波形在一定数据窗下进行相关度分析，籍此形成选线判据，实现选线。

From the perspective of minimum transmission losses, an instantaneous reactive power theory for systems with any number of phases and with or without neutral line is developed. Under the new definition, each quantity has its own physical meaning, and the zero sequence current can be decomposed into active and reactive components. Furthermore, a generalized compensation method for zero sequence current is developed.

从输电损耗最小的角度出发，提出了任意相无中性线或有中性线系统的瞬时无功功率理论，在新的理论下，每个量都有清晰的物理意义，且能分解出零序电流的有功分量和无功分量，并给出了通用的零序电流补偿方法，揭示了瞬时无功功率理论与传统平均意义下的无功功率理论的联系及本质区别，从而为研究HVDC-VSC及各种FACTS装置的无功功率控制奠定了理论基础。

A line considered a limit to a curve in the sense that the perpendicular distance from a moving point on the curve to the line approaches zero as the point moves an infinite distance from the origin.

渐近线与曲线极限相关的一条直线，当曲线上某动点沿该曲线的一个分支移向无穷远时，动点到该直线的垂直距离趋于零

A line traced by a point traveling in a constant direction; a line of zero curvature.

一个点在一个方向上移动所产生的线；有零个弯曲的线。

Line scale is engraved on the front of a carved-foot line as the ruler's zero, as Figure 6-1-1b shows, when measured at a distance of access to high accuracy.

刻线尺是以尺前端的一条刻线作为钢尺的零点，如图6-1-1b所示，在距离丈量时可获得较高的精度。

This invention relates to a cascade multiple zero-type matrix rectifier, in which, a general input filter is connected between a net and a step-down transformer to get sine-wave input current, the step-down transformer includes n secondary windings with Yn spliced mid lines, the phase of all the three-phase windings is the same, the rectifier array is arrayed in a 1 row x n lines by n zero-matrix rectifier units, each line of which is connected with the seconday winding of the step-down transfornmer, and the outputs of the rectifier units are serial orderly to form a DC output, the general controller is responsible for regulating work of the entire system and connected with the branch controllers by signal cables to control the work of the rectifier units in the array.

本发明涉及一种级联多重化零式矩阵整流器，总输入滤波器连接在电网与降压变压器之间，滤波得到正弦波形的输入电流，降压变压器有n个Yn接带中性线的次级绕组，所有三相绕组相位相同，整流器阵列由n个零式矩阵整流器单元排成1列×n行的阵列，阵列中每一行与降压变压器的一个次级绕组对应连接，阵列中整流器单元的输出依次串联，形成一路直流输出，总控制器负责控制调节整个系统的工作，并通过信号电缆与各个分控制器联络，控制整流器阵列中每个整流器单元的工作。本发明由低压小功率的变换器串联得到幅值可调的高压直流电源，同时在电网侧得到位移为零的输入电流，具有网侧四象限运行能力等优点，适用于中高压直流供电领域。

If the specified line is out of range, the start line is set to zero.

如果指定行超出范围，起始行则设为零。

As a general rule, no more that 15 consecutive zeros can be transmitted without violating the ones density rule. B8ZS (Binary 8 with Zero Substitution), the newer line coding technique used in T-1 circuits, substitutes alternating bipolar pulses for the eighth zero in a string of eight consecutive zeros. B8ZS also supports clear channel communications of 64 Kbps per channel.

作为一种通用规则，不存在连续15个以上0序列被发送而又没有违反信号密度规则。T-1电路中使用的最新的线路编码技术B8ZS（二进制八0替换法）在信号传输中出现连续8个0时，将使用交替双极脉冲替换这8个0.B8ZS也支持64kbps信道的纯信道传输。
