查询词典 null hypothesis

It can be used in SDTV or HDTV stream multiplex in real time. Furthermore the technology of CBR multi-program multiplexing is researched. It presents inserting the PSI information and designwith the input and output buffer. It proposes the methods of using reconstructed the null packet to recover the PCR information when demultiplex and by utilizing modification PCR to remove the dithering of PCR when multi-program multiplex processing.

研究了基于CBR方式的多节目复用技术，给出了多节目复用PSI信息的维护和输入输出Buffer的设计，提出了采用空包重建的方式将多节目TS流解复用为单一的携有原有PCR信息的TS流以及利用PCR修正实现多节目复用PCR抖动的校正，并对帧平移法统计复用进行了研究，给出了仿真结果及性能。

The main problem studied in this thesis are properties of positive solutions to a semi-linear parabolic system with non-local nonlinear sources and null Dirichlet boundary conditions.

中文摘要：本论文主要研究了具有非局部源的半线性抛物系统并附加Dirichlet零边值的解的性质，得到了系统古典解的渐近性分析：blow-up速率、blow-up集、边界层估计等问题。

The main problem studied in this thesis are properties of positive solutions to a semi-linear parabolic system with non-local nonlinear sources and null Dirichlet boundary conditions. We give the analysis about asymptotic property: blow-up rate, blow-up set and blow-up profiles.
