Specifies the angle of the orientation of the device screen that can be accessed by the 属性访问的设备屏幕的取向角。
The settling behaviors of the rectangular particle were affected significantly by the initial orientation angle and length - width ratio 粒子的初始取向角和长宽比对其沉降过程有较大影响。
The settling behaviors of a rectangular particle with different initial orientation angles and length - width ratios were simulated by using distributed lagrange multiplier / fictitious domain method 摘要为了对方形粒子在二维垂直通道中的沉降运动特性进行研究,应用了拉格朗日乘子虚拟区域方法对不同初始取向角、不同长宽比情况下方形粒子的沉降运动进行了直接数值模拟。
With the increasing initial orientation angle and length - width ratio , the drifting distance , the fluctuation of the orientation angle , lateral drifting velocity and rotation velocity all increase , while the final settling velocity decreases with the increasing length - width ratio 初始取向角和长宽比增大,则粒子的横向漂移以及取向角、侧向漂移速度和转动角速度的振荡幅度都增大;同时随着长宽比的增大,粒子的沉降速度相应减小。
