The larger the absolute value of sensitivity in the location of the disperse phase medium and the size of the disperse phase medium , and the greater the difference of conductivity between the disperse phase and continuous phase medium , the greater the effect of the disperse phase medium on the sensitivity distribution 同时离散相介质所在处灵敏度的绝对值、所占区域、其电导率值与连续相介质的电导率的差值越大,对灵敏场分布的影响也越大。
Under the same restriction of a universal sdr hardware platform , the demodulation of linear modulated waveform , continuous phase ( no - linear ) modulated waveform , and multi - carrier modulated waveform , are investigated . corresponding to those three modulation schemes , bust mode mpsk , omsk , and ofdm signals are taken as the examples to implement a multi - mode sdr receiver , and results are presented 本文在软件无线电通用硬件平台结构下,分析了线性调制方式、非线性连续相位调制方式和多载波调制的软件接收机实现问题,分别以突发模式mpsk调制、 gmsk调制、 ofdm调制模式为对象,给出了具体的多模式接收实现方法和仿真结果。
Two kinds method of design binary subwavelength diffractive microlenses are illustrated with emphasis . i obtained the result that the method of subwavelength pulse - width modulation is better than the method of linear approximation for continuous phase piece in designing binary subwavelength diffractive microlenses by comparing them 重点说明了二台阶亚波长衍射微透镜的两种设计方法,并对两种方法作了比较,得出了亚波长结构的脉冲宽度调制法优于连续位相的线性进似法的结论。
Result of numerical simulation shows that the grads of continuous phase " s velocities decreases with the presence of microbubble of which the diameter is 100 / / w , the profiles of air volume fraction in the boundary layers is similar to triangle or echelon , affected by interaction among the particle , there is a saturated air fraction , within the scope of saturated air fraction , increasing the air injection ratio can accrete the friction reduction ratio , under the condition of same air injection ratio , the free - steam velocity is larger , the effect of friction reduction is worse 计算结果表明,直径为100 m的微气泡能减小近壁面连续相的速度梯度;微气泡在边界层中的浓度分布近似为三角形或梯形分布;受粒子间相互作用的影响,存在一饱和浓度;减阻率随喷气量的增大而增大,直至饱和喷气量,此后,增大喷气量,壁面摩擦阻力变化不大;相同喷气量下,来流速度越大,减阻率越低。
By means of a detailed analysis to the interaction between droplet and its carrying fluid for horizontal stratified / atomization two - phase flow , a theoretical model is proposed to calculate the droplet axial velocity profile and the relative slip between dispersed phase and continuous phase 摘要通过对水平分层雾化流中液滴和其携带流体间交互作用的分析,提出了一个预则水平分层雾化流中轴向液滴速度分布以及弥散相和连续相之间相对滑移的理论模型,通过计算获得了两相速度参数及相对滑移参数。
