Can know from Figure 1, the growth media from a disadvantaged position the media, the strategy can go no more than two paths, one from the quadrant III Quadrant IV as the first arrival of the first I quadrant, that is, to raise the audience to reach, and then to raise the audience loyalty achieved; the second from the first quadrant III arrived by the first article I Quadrant II Quadrant, which is to raise the audience loyalty, and then raise the audience to reach to achieve.

由图1 可以知道，从一个弱势媒体成长为强势媒体，可以走的策略路径无非两条，其一由第III象限经第IV象限到达第I象限，即先提高观众到达，再提高观众忠诚来实现；其二由第III象限经第II象限到达第I象限，即先提高观众忠诚，再提高观众到达来实现。

According as different projection of point of fall for Rocket in XOZ quadrant, the correction points are searched with the method along OX axle for errors point of fall, first correction point is searched in first quadrant, second t correction point is searched in second quadrant, third t correction point is searched in third quadrant and so on.

该方法以炮弹落点在XOZ象限投影的不同，沿落点偏差轴OX 寻找推冲点：第一象限一次可寻找到第一修正点，第二象限则应寻找第二点，以至第三点。

The invention refers to a method to correct universal frequency of electric communication technique, its character: make signal index quantization on the complex number of cross product, to directly reflect the quantized numerical value of tangent value and the located quadrant of imaginary and real parts, use inverse tangent ROM table to discriminate the processed result, then make loop filter and phase accumulation on the discriminated result to obtain error-correcting angle, and use digital controlled oscillator to make table look-up and quadrant adjustment to obtain correcting factor; use the relationship of trigonometric function in each quadrant to compress inverse tangent look-up table ROM and digital controlled oscillator look-up table ROM.

一种涉及电通信技术的通用频率纠正的方法，其特征在于：它采用如下步骤：经过叉积的复数进行信号指数量化处理，通过该复数虚、实部信号的指数量化结果的差值及其极性直接反映虚、实部的正切值的量化数值以及所处象限，将处理后的结果通过反正切ROM表进行鉴频，鉴频后的结果经环路滤波和相位累加，得纠偏角度，通过数控振荡器针对纠偏角度进行查表和象限调整，得到纠正因子；通过个象限之间的三角函数关系来压缩反正切查表ROM和数控振荡器查表ROM的大小，本发明资源耗费小，效率高，可极大地节省内存资源。
