象限

In order to save the CPU time, the approach of searching its nearest generator for a grid was developed, which was based on the quadrantal location of generator grids in a raster space.

为了减少计算时间，设计了一种搜索某个栅格所属最近发生元的方法，它是根据对于该栅格而言发生元栅格所处的象限位置来计算的。

The Quadrantid and Delta Aquarid meteor showers may also be involved.

另外，象限仪座流星雨和宝瓶δ流星雨也可能和它们有关。

The Quadrantid meteor shower and the meteor speed during the period of this meteor shower are successfully observed using the Wuhan meteor radar for the first time, and then the correlative questions of observing meteor shower using the all-sky meteor radar are also discussed.

利用武汉流星雷达，首次成功地观测了象限仪座流星雨及流星雨期间的流星速度，讨论了利用单站全天空流星雷达观测流星雨的相关问题。

The observational result shows that this Quadrantid meteor shower occurs between 0000 to 0800 local time in January 4, 2004, with meteor echoes peaking at 0400 local time. Moreover the meteor shower radiant derived from the meteor echoes plane, which is formed by the whole meteor echoes observed by the meteor radar during this shower, accords well with the theoretic radiant of this meteor shower.

从观测结果可以发现此次象限仪座流星雨发生在2004年1月4日的0000-0800LT，其中流星峰值出现在0400LT，而且通过流星雷达观测到的流星雨期间的流星回波平面推测得到的流星雨辐射点也与该流星雨的理论辐射点位置对应非常好。

Other astrologers believed that by adding one aspect to another the sesquiquadrate, a square plus a semi-square, and the quincunx, a square plus a sextile, could be created. Some thought that the quincunx was made up of five semi-sextiles, or that it was the inversion of the semi-sextile.

其他的占星家相信在另一个半象限差加上一个相位，可以创建新的相位，一个4分加上一个8分，以及梅花形，一个4分加上一个6分。

If, for example, you major in‵mathematics, you're going to wander into class one day ｜and the professor will say:①"Define the cosine integer｜of the quadrant of the rhomboid ‵binary axis, and extrapolate your result to five significant vertices."

例如，你主修数学，一天，你闲逛着走进教室，老师说：①"请定义菱形二元坐标象限的余弦积分，并将结果推广到五个有效顶点的情形。"

For square mesh point and round dot, this is used in a quadrant in can no longer cause the fourth ideal point of view, the worst angles to it.

对于不方形网不面和方形网不面来说，当在一个象限洋无法再安插第四个抱负角度时，最不对的角度不离给了它。

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。
