second quadrant

Magic-T1 connection first and second quadrant of the feed waveguide, and the magic-T2 connecting the third and fourth quadrant of the feed waveguide.

魔T1连接第一、二象限的馈电波导，魔T2连接第三、四象限的馈电波导。

As to the design of the second-stage I-O stable, that the third quadrant should increase the vector of labor income and the government consumption should reserve at the second quadrant, etc are put forward.

针对二阶段投入产出表的设计，提出了第三象限应增加劳动报酬剩余行向量、政府消费保留在第二象限等新构想。

Second, the light to see what quadrant is not enough.

其次, 光看哪个象限还不足够.

The line AB lies in the second quadrant.

线段AB是处在第二象限中.

The analysis indicates that the stable easterly stream provided by the second quadrant of the outside of the typhoon and its disturbance constitute the mesoscale easterly stream convergence line synoptic system which results in heavy rain.

经综合分析表明：暴雨期间，在台风外围第二象限稳定的东风气流，并发生扰动，构成产生特大暴雨的中尺度东风辐合线天气系统。

The EIS behaviors were different which obtained at various polarization potentials. The capacitance semi-circles with negative differential resistance transfer from the first quadrant to the second quadrant had been observed which marked the nature of passivation.

不同极化电极电位下的电化学阻抗行为不同，EIS图谱观察到的由第一象限向第二象限转移且具有负电阻的容抗弧，标志着钝化的本质。

The rapid optimal switch curve of second order system is in the second and the fourth quadrant
