相位角

Gastaldi and co-workers have observed two types of contrasts in Al-Pd-Mn IQCs: black-white double-lobe and loop-shaped, by using X-ray topography, and the facetted dodecahedral pores by phase-sensitive radiography.

Gastaldi领导的小组在结合利用X射线形貌术以及相位敏感成像术研究Al-Pd-Mn二十面体准晶单晶中的缺陷时发现两种衬度，其中已知黑白双瓣衬度是由于准晶中的五角十二面体空洞引起，而对于环形衬度则除了知道退火行为不同于位错从而不太可能是位错圈外，基本上对其缺陷的几何及性质不甚了解。

Our studies showed that the PADs in few-cycle laser pulses were determined by the kinetic energy of photoelectrons, the absolute phase of the carrier wave, and the ellipticity and the duration of the short pulses.

The view was acquired at a Sun-Enceladus-spacecraft, or phase, angle of 73 degrees.

这幅景观是在太阳－恩克拉多斯－太空船这样的角度下拍摄完成的，或者用相位来讲，以73度角拍摄。

A new algorithm for linear array position calibration is presented. In the case of source direction-of-arrival is uncertain, by using the least square algorithm, the source DoA is estimated based on the unwrap phase of the steering vector.

Methods Six normal volunteers were examined with 1.5 T MRI scanner, and stimulated with the pattern of phase-encoded polar angle with clockwise or counterclockwise rotating wedges, and the pattern of eccentricity with concentric expanding or contracting rings.

方法采用1.5T超导MR设备，运用2种具有相位编码信息的投影刺激：离心外散和向心内聚的光环刺激，以及顺时针和逆时针方向旋转的极角刺激，对6名正常人进行血氧水平依赖的fMRI。

Using CHAMP observational data samples, the profiles of atmospheric bending, refractivity, pressure, and temperature were retrieved in turn by the series of signal noise ratio.

Since the first discovery of pulsar in 1967, static dipole field has been used for a long time to represent pulsar magnetic field in the study of rotating vector model, which is used to interpret the variation of linear polarization position angle with pulse phase.

1967年发现第一颗脉冲星以来，在用于解释线偏振位置角随脉冲相位变化曲线的旋转矢量模型中，脉冲星磁场通常被近似为静态磁偶极场。

The algorithms estimate the DOA of the broadband distributed source fron the secondary diagonal elements of the covariance matrices generated from every frequency domain of the received broadband signal s, thus avoiding unwrapping of phases.

该类算法首先将阵列接收的宽带信号变换到频率域，然后对于每个频率形成阵列接收信号协方差阵，最后由该协方差阵的次对角线元素估计宽带分布源的到达角，其主要特点是避免了相位展开。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
