查询词典 phase angle

The scattering properties of particles with different shape parameters are simulated respectively in the modes of reflection and refraction. Both in the modes of reflection and refraction, the phase difference of non-spherical particle's PDA signal is the unbiased estimate of the corresponding phase difference of ideal spherical particle, and the standard deviation of angle roughness scale on particle surface impacts little on the distribution of phase difference.

Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron, and there is an emergence angle in which the electron has the maximum trajectory length and impact energy, Impact energy will increase and return time will reduce as increasing the amplitude of electric field, and both parameter would oscillate with the phase of electric field, which can essentially explain that multipactoring electron number oscillates in twice the frequency with the increase of microwave frequency, electron trajectory will change from parabolic-like movement to complex oscillation.

研究发现：电子出射角度对其运动状态有显著影响，电子存在运动轨迹最大的某一出射角度，该角度下电子拥有最大的撞击能量；微波电场幅值的增加将使电子撞击能量增加，返回时间减小，微波电场相位的变化使电子的撞击能量和返回时间呈周期振荡，这从本质上解释了电子数量在二次电子倍增过程中以微波频率两倍周期振荡的原因；随着微波频率的增加电子将由简单的类抛物线运动转变为复杂的振荡运动。

再生型切削颤振是切削颤振的主要形态，通常所说的切削颤振控制技术从某种意义上说就是控制再生型切削颤振孕育成长的技术。

The definition of generator angle is proposed in this paper. A new method to deduce generator angle by using rotor rotation signal is illustrated, which compares the phase difference between GPS timing pulse and RRS. Using only mechanical signal, the technique unfreezes limitation of zero-cross of generator terminal voltage during transient process. Automatic correction of initial generator angle is also proposed .

本文介绍了同步发电机绝对转子角的定义，提出了一种测量绝对转子角，进而获得高精度的相对转子角的方法；此方法不使用机端电压过零整形脉冲，而是将机组键相脉冲与GPS 定时脉冲比相，并能够自动整定初始位置角，因此，测量结果不受发电机运行状态的影响，能够在各种运行方式和扰动情况下获取高精度的绝对转子角。

Shoulder angle in sagittal view was increase sustained, but elbow angle in sagittal view was from increase to decrease in second pull phase of snatch. This result indicated that the upper arm was leaving forward the trunk, and the movement of elbow was from extention to flexion, in second pull phase of snatch.

肩关节矢状面角度在发力过程中持续增加时，肘关节矢状面角度则是先增加而后减少，这意谓著参与者的上臂在发力的过程中是有向前逐渐偏离躯干的情况产生，并且肘部的动作是先伸展而后屈曲。

Firstly, the control of reentry phase and the model of RCS jets are presented. Then the flight control system is divided into two subsystems based on the time-scale separation principle. The fast states subsystem corresponds to the three body-axis angular rates, the slow states subsystem controls the angle-of-attack, sideslip angle and the rate of the bank angle about the velocity vector. Lastly, the proportional-plus-integral feedback is designed to increase the system robustness.
