Microfluidics is the minitiarization of fluid - based biochemistry to very small volumes such that a large series of chemical reactions can be performed in parallel in a microarray format ( see microarray ) 显微流是将液相生化反应缩小至非常小的量,这样大系列的化学反应可以在相同的微点阵状态下进行。
The dominating scattering of the aircraft is from the engine inlet , so the analysis and reduction of the electromagnetic scattering from the interior of jet engine inlet cavity have been an important research area 进气道终端为发动机涡轮,结构非常复杂,在波长或更小的量级上有复杂的几何尺寸变化,一般的高频技术不再适用。
This paper also discussed the factors that influenced the diffraction efficiency of scattering object , and proposed the amount of refraction index modulation was very small , the diffraction efficiency was mainly determined by chemical treatment 并指出体积光栅效应对透射全息衍射效率是有贡献的,讨论了影响散射物体全息衍射效率的问题,最后指出在一般情况下,调制折射率是一个很小的量,化学处理对它起着关键性的作用。
