intercept point

Intercept point size and body mass index, neck circumference-negative correlation, but smaller correlation coefficient.

阻塞点截面积与体重指数、颈围呈负相关性（P0.05），但相关性系数较小。

Based on this, two rational measurement methods for the third-order intercept point are brought forward.

探讨了三阶截点与三阶互调以及三阶截点与1dB压缩点之间的相互关系，给出了三阶截点的两种合理测试方法。

The dissertation also shows some methods used for charactering nonlinearity of devices, such as AM-AM, AM-PM, Intermodulation Distortion and Third-order Intercept Point.

同时也介绍一些表征器件非线性特性的方法，如AM-AM、AM-PM、交调失真以及三阶截交点等理论。
