The amplitude of a complex number.

复数的辐角

is applied to construct the three-dimension model for finite element analysis. Short circuit and open circuit of the field winding and the teeth and slots structure of the rotor are discussed. An appropriate three-dimensional mesh is made. The corner point problem of conductor is eliminated. Furthermore, a new memory structure for sparse complex matrix and a PCCG method based on it are introduced to save memory and computation time.

在汽轮发电机失磁异步运行转子三维涡流场数值计算模型中，应用了〓法建立了三维有限元计算模型，考虑了转子绕组的开、短路状态及转子齿槽结构，形成了合适的三维剖分网格，解决了三维电磁场有限元计算中角点奇异的问题，创立了一种新的稀疏矩阵的存储格式以及基于该格式的预处理复数共轭梯度法从而减少内存开销和加快了求解速度。

Then the MUSIC-like algorithm based on the hypercomplex eigenvalue decomposition is used to estimate the direction of arrival of signals.

在此基础上应用基于超复数奇异值分解的超复数MUSIC算法进行波达角估计并进行计算机仿真。

Received the asphalt mixture mechanics performance index with frequency through FSCH test, it point out that the complex shearing modulus: G*, G*/sind can appraise the high-temperature performance of different asphalt mixture well. But phase angle: d can't relatively produce quality of high-temperature performance of every asphalt mixture obviously.

通过FSCH试验得到不同频率下沥青混合料力学性能指标，指出复数剪切模量G*、G*/sinδ能较好地评价不同沥青混合料的高温性能，而相位角δ不能明显地比较出各沥青混合料高温性能的优劣。

The angle made with the positive horizontal axis by the vector representation of a complex number.

幅'。''角代表一个复数的矢量与正实轴之间的夹角

Based on the estimation of the directions of arrival and the Doppler frequencies of the sources, a quaternion model was proposed, which made the estimation of the DOA and the Doppler frequencies similar to that of one-dimensional azimuths so as to avoid direct and indirect pairing with the complex model.

针对阵列信号处理中方向角、多普勒频率的同时估计问题，提出了方向角、多普勒频率的四元数模型，使估计方向角、多普勒频率二维问题与估计一维问题相类似，从而避免了在经典的二维复数模型估计中直接或间接的配对。
