定位几何学
Examples
- Radix 2 fft algorithms is analyzed , and fixed geometry configuration and blocking floating format of data is used to implement 256 points 12 bit complex numbers fft
并在分析了基2fft算法的基础上,采用固定几何结构和块浮点数据格式,实现了256点12位复数点的fft运算。 - The numerical results of the dispersion relation show some nonlinear effects : for a fixed geometry of a waveguid , beam parameters and plasma density , the increment of the modulation parameter may lead to a slight increment of the operating frequency , however , as the modulation parameter increases further , saturation may occur and the dispersion relations are hard to be separated , it is due to the overmodulation of the microwave power , this phenomenon itself belongs to the nonlinear effects
对于一定的波导、电子注参量和等离子体密度值，等离子体调制系数的增加，使工作频率略微升高。但是，随着等离子体调制系数的进一步增加，色散曲线变得彼此之间不可分辨，可以认为是等离子体的过调制导致了栅的饱和。这一现象是非线性的，可见，等离子体栅和调制场中文摘要是非线性关系，等离子体栅是非线性j 。 - In this paper , maccormack explicit time - split scheme , baldwin - lomax algebraic turbulent model and two - steps hydrogen - air nonequilibrium chemical kinetics model are employed to simulate the 2 - d flow fields in a fixed geometry scramjet combustor in different injecting way of fuel in different flight conditions . the results show , in the same entrance condition , the operating mode of scramjet combustor is influenced by the control of fuel
本文采用maccormack显式时间分裂法、 b - l代数涡粘性湍流模型及氢-空气两步非平衡化学动力学反应模型，模拟了在不同的飞行马赫数条件下，固定几何的双模态燃烧室在不同供油规律下的二维燃烧流场。
