流動再壓縮 的英文怎麼說
中文拼音 [liúdòngzàiyāsuō]
流動再壓縮
英文
flow recompression-
In this work, we detailedly introduced the whole ideas of rkdg finite element method and the theory of constructing gas - kinetic schemes based on boltzmann equation. and then presented a kind of new computational method for solving id and 2d compressible euler equations, i. e. firstly, we discretize euler equations in the space with discontinuous galerkin finite element method ; secondly, we discretize temporal variable t with runge - kutta formula ; thirdly, for numerical fluxes constructing, we give two kinds of different numerical fluxes - kfvs and bgk numerical fluxes by using gas - kinetic schemes
本文分別對rkdg有限元方法的整個思想和基於boltzmann方程的分子動力學格式的構造思想給予了詳細的介紹,並分別結合rkdg有限元方法與kfvs數值通量和bgk數值通量的構造方法,給出了一種求解一維、二維可壓縮流體力學方程組新的計算方法,即,我們先用間斷有限元方法進行空間離散,然後再對所得到的半離散格式使用runge - kuttatvd方法進行時間離散,得到全離散格式。The algorithm study is in detail that one channel of video - stream is recompressed by mpeg - 2 standard so that its bit - rate will be changed lower. then, multi - date streams will be processed by the technology of statistical remultiplex. the dynamic signals of every single data - stream " output can drive the values of bit - rate of the corresponding single data - stream
本次演算法研究具體地說就是按照mpeg - 2的標準對單路mpeg - 2視頻流再次壓縮,將其碼率變的更低,並且提出對多路碼流進行統計復用,根據單路碼流的輸出動態信息對碼流進行動態的調整的框架。
