The representation of aaf and its resolution not only enriches relative theory of radar signal processing and is instructive in radar parameter design and performance analysis , but also provides a practical method to quantitatively evaluate the acceleration effects on signal processing 加速度模糊函數(shù)及其分辨力的概念不僅豐富了雷達(dá)信號(hào)理論的有關(guān)內(nèi)容,為雷達(dá)參數(shù)設(shè)計(jì)和性能分析提供了一定的指導(dǎo)意義;而且也為實(shí)際工作中定量地衡量加速度對(duì)信號(hào)處理的影響提供了分析手段。
All these indicate the transformation of scientific and technological system from state - owned to enterprise - owned , from high intensive to harmony . in the end , from the viewpoint of the integration of science & technology and economy , the thesis demonstrates the positive acceleration effect of the scientific and technological system transformation on the development of economy 這些特征昭示著我國(guó)科技體制從政府型科技體制向企業(yè)主體型科技體制的變遷,從高度集中型科技體制向集中協(xié)調(diào)型科技體制的變遷。最后,論文從科技與經(jīng)濟(jì)一體化發(fā)展的角度,論證了我國(guó)科技體制的變遷對(duì)經(jīng)濟(jì)發(fā)展的促進(jìn),肯定了這種變遷趨勢(shì)對(duì)促進(jìn)科技成為經(jīng)濟(jì)增長(zhǎng)和經(jīng)濟(jì)發(fā)展的關(guān)鍵要素的意義。
In order to know the relationship between gas - content and pipeline ' s pressure drop , the thesis deduces the pressure drop calculating equations based on uniform flow pattern and separating flow pattern . the equations show that pressure drop is made up of three parts , that is , friction resistance effect , gas acceleration effect and the gravity effect . and the research has shown that the gas has little effect on pressure drop . in the horizontal pipeline , the resistance effect must be overmatched the acceleration effect 為探討加入的氣體對(duì)管道壓力的影響,本文基于分相流和均相流兩種模型分別推導(dǎo)了三相流管道的壓降公式,表明無論是分相流模型,還是均勻流模型,管道內(nèi)流體總的壓降是由三項(xiàng)組成的,即摩擦項(xiàng)、加速項(xiàng)和重力項(xiàng),并得出了加氣對(duì)管壓變化不大的結(jié)論,所以認(rèn)為在水平管道中,要獲得有效的減阻,則要使摩擦阻力分量的減小效應(yīng)大于漿體加氣的加速效應(yīng)。
The formation of holographic gratings accompanied by 532 nm irradiation was studied in detail . it was found that the effect of 532 nm laser to the holographic grating lay in two aspects : the acceleration effect of 532 nm laser to the formation of holographic grating is predominant when the intensity of 532 nm laser is low ; while at relatively high intensities of 532 nm laser , the erasure is the main factor to the holographic grating 論文詳細(xì)研究了在伴隨光532nm照射下全息光柵的形成過程,發(fā)現(xiàn)532nm激光對(duì)于光柵的形成存在兩方面的影響:當(dāng)532nm激光功率較低時(shí),對(duì)于全息光柵的形成起主要作用;當(dāng)532nm激光功率較高時(shí),對(duì)于光柵的擦除作用為主。
