We analyze the statistical characteristics of bimodal noise thoroughly , that provides theoretical basis for models transformations & precise estimations of noise & signal parameters 深入分析了双模噪声模型的统计特性，为模型转换及精确估计噪声和信号参量提供了理论依据。
It adopts double extrusion - dies with compounded double - roller to make even compounding . its finished products are all high intensity and good performance both in application and appearance 采用挤出双模头，复合双胶棍使制品复合均匀，剥离强度大，整体力学性能好外形平整美观。
In the introduction the review of the research on a dual - mode scramjet combustor both abroad and domestic is presented and the main work of this paper is also presented briefly 第一章为引言，简要回顾了国内外双模态冲压发动机燃烧室研究的现状，并在结尾介绍了本文的主要工作。
On the estimation of signal & bimodal noise parameters , some foreigners give out approximate estimation , which is applicable only on some condition ; we give out the precise estimation 对于双模噪声与信号参量的估计，国外给出了近似估计，只在一定条件下适用：本文给出了精确估计。
Not only the quantum entanglement between the atom and two - mode squeezing vacuum state is studied , but also the quantum entanglement between two modes of the two - mode light field state is studied 这里不但讨论了原子和双模压缩真空态的纠缠，而且讨论了双模缩真空态在与原子作用过程中两个模间的纠缠。
