It is proved by the analytical and numerical method that the modulus of the Z transform of a finite impulse response sequence has no extreme values at poles (with maximums along imaginary axis and no extreme values along real axis), and the negative second order derivative of the modulus normalized along frequency axis with respect to angular frequency has maximums at the poles.

根据实测瞬态电磁脉冲响应，较好地反演了导体球和导体长椭球的冲激响应，测得了它们的雷达截面和谐振频率。用解析与数值相结合的方法证明了有限冲激响应序列Z变换的模在极点无极值（沿虚轴有极大值，沿实轴无极值），而沿频率轴的归一化值对角频率的负二阶导数在极点有极大值。

Picker-wheel support structure was used in strip label papers of tobacco industry, but it had appeared some problems: picker-wheel vibrates easily, label paper was picked insecurely, and double-shafts generated deformation and linear bearings wear easily. The ultimate cause was founded by analyzing linear bearings stress from statics and dynamics. The original structure of double-shafts one-side support was replaced by two-side support with one fixed end and one free end.
