查询词典 Z

The material parameters in the hyperbolic sine constitutive equation were determined with regression analysis, and the DRX activation energy was thus obtained to be 269 kJ/mol. The relationship between critical strain, peak strain/stress and the dimensionless parameter Z/A were established by linear regression.

To detect more targets, the whitened data Z are projected onto the orthogonal subspace of w using the orthogonal subspace projector P⊥= W I .W.1WT, to eliminate the detected target, where I is an L×L identity matrix and W =.

为了要发现较多的目标，被数据白的 Z 被在 w 的直角次空间之上使用直角的次空间投光器 P 第一⊥= W 计画。W。，除去那发现了我是 L × L 身份点阵式和 W=的目标。

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。

Based on the low-velocity impact test, 4 major modes of low-velocity impact damage including delamination and matrix cracking were taken into account FEM simulation. By using appropriate failure criterion, the low-velocity impact damage of z-pin reinforced laminates can be identified.
