In this work,the gyrokinetic eigenvalue code LIGKA,the drift-kinetic/MHD hybrid code HMGC and the gyrokinetic full-f code TrIMEG-GKX are employed to study the mode structure details of reversed shear Alfvén eigenmodes(rSAEs).Using the parameters from an ASDEXUpgrade plasma,a benchmark with the three different physical models for rSAE without and with energetic particles(EPs)is carried *** agreement has been found for the mode frequency and the growth *** structure symmetry breaking(MSSB)is observed when EPs are included,due to the EPs’non-perturbative *** is found that the MSSB properties are featured by a finite radial wave phase velocity,and the linear mode structure can be well described by an analytical complex Gaussian expressionФ(s)=e^(-σ(s-s_(0))^(2))with complex parametersσand s_(0),where s is the normalized radial *** mode structure is distorted in opposite manners when the EP drive shifted from one side of qminto the other side,and specifically,a non-zero average radial wave number with opposite signs is *** initial EP density profiles and the corresponding mode structures have been used as the input of HAGIS code to study the EP *** parallel velocity of EPs is generated in opposite directions,due to different values of the average radial wave number,corresponding to different initial EP density profiles with EP drive shifted away from the qmin.

气流状态对纺纱准备工艺过程有巨大影响，因为气流的状态不仅会影响纤维的运动关系和实际工艺过程，而且会影响到杂质的去除。纤维状物质和非需要的杂质粒子的分离需要由气流来实现。研究人员采用新的测试技术，如使用ＬＤＡ（激光多普勒测速仪）已经能够研究气流和纤维的速度。ＬＤＡ技术通过非接触式方法在生产状态下测定纤维速度而且不会影响气流状态。由于这种测试斩传感器小而且容易操作，故可应用于难以接触的环境中。因而。

人为因素是对工程学、实验心理学、神经科学、计算机科学和人类工程学的一种折中组合，按照字面意思来看，即为“工作科学”。它是应用科学的方法和原理来研究、设计、维修和操作复杂的人一机器系统。人为因素不但针对个体、小组和团体，而且针对控制、显示和作业。人为因素工程的首要目标，一是通过使人适应机器来优化系统的性能，例如，通过培训使操作人员熟悉机器；二是通过使机器适应人来优化系统的性能，例如，通过应用诸如“控制一显示兼容”的设计原理使机器适用于操作人员。简而言之，人为因素是系统工程的一个关键的中心组成部分。
