A new method for precursory information extraction, i. e. slope difference information method is proposed in the paper for the daily mean value precursory data sequence.

Therefore, the normalized slope of difference pattern arrives at 1.4 with a particular monopulse feed.

因此，使用特殊设计的单脉冲馈源可望将归一化差斜率提高到1 .4。

There is little difference between the two mean temperature fields, except that the slope of the isotherms appears to be somewhere greater in the right panel.

这两个平均温度场没有什么差异，除了右图等温线的坡度似乎略为大一些之外。
